## 1. The Fundamental Business Paradox

No other class of healthcare provider operates the way DMEPOS suppliers do.

A physician bills after the visit. A hospital bills after discharge. A pharmacy
fills a prescription and collects at the counter. But a DMEPOS supplier —
whether providing a CGM system, a wheelchair, or an insulin pump — must first
**purchase the equipment, deliver it to the patient, and then hope the claim
gets paid** on the back end.

The financial exposure is not theoretical. It is structural.

```
DMEPOS CASH FLOW MODEL vs. OTHER HEALTHCARE PROVIDERS
──────────────────────────────────────────────────────────────────────

  Physician / Hospital / Pharmacy
  ─────────────────────────────────
  Service Rendered → Claim Submitted → Payment Received
  ▶ No capital at risk until claim is submitted

  DMEPOS Supplier
  ─────────────────────────────────
  Equipment Purchased ──▶ Supplier Pays (Day 0)
         │
         ▼
  Equipment Delivered to Patient ──▶ Patient Has Product
         │
         ▼
  Claim Submitted ──▶ Payer Reviews
         │
         ├──▶ APPROVED → Payment received (30–90 days later)
         │
         └──▶ DENIED   → Supplier absorbs full product cost
                          + delivery cost
                          + staff time on appeal
                          + often provides continuity product anyway
                            (see Section 5)

──────────────────────────────────────────────────────────────────────
Capital risk window: Day 0 through Day 90+ on every single order.
```

This model exists because Medicare Part B (which covers DMEPOS) was designed
around a "reasonable and necessary" determination that happens *after* delivery.
Suppliers are not hospitals with credit lines and cost-shifting mechanisms. Most
are small businesses — often 5 to 50 employees — absorbing full product cost
risk on every shipment.

The practical consequence: **documentation problems in the referring physician's
office or payer system become the supplier's financial liability, not the
physician's.** The supplier delivered the product in good faith; the payer
denies the claim for reasons entirely outside the supplier's control.

```

A 38% decline over a decade is not attrition — it is structural contraction.
The causes are layered: competitive bidding rate reductions, documentation
burden increase, payer audit escalation, fraud-related moratoria, and the
general inability of small operators to absorb increasing overhead without
scale. Section 8 covers this in detail.

## 3. The Denial Crisis — Industry-Wide

```

### Why DMEPOS Feels This Disproportionately

For hospitals and physician groups, a denied claim is a revenue cycle problem —
painful, but recoverable through appeals, write-offs, or renegotiation.
For a DMEPOS supplier, a denied claim on already-delivered equipment means:

- **Revenue not received** on a product already paid for
- **Staff time** spent on appeals (often $25–$118 per appeal attempt)
- **Patient continuity pressure** — the product is already in the patient's hands
- **No cost-shift mechanism** — unlike hospitals, suppliers cannot adjust charges

---

## 4. CGM-Specific Denial Anatomy

CGM claims are particularly denial-prone because coverage requires a documented
chain of events that spans multiple parties: the patient, the prescribing
physician, the DME MAC (Medicare Administrative Contractor), and the supplier.
A failure at any link — none of which the supplier controls — lands as a
supplier liability.

### CGM Improper Payment Breakdown (Medicare 2024)

  │ Insufficient documentation      │  26.6%   │ ████████

────────────────────────────────────────────────────────────────────
94.2% of CGM improper payments trace directly to documentation
failures — not fraud, not medical necessity disputes, not billing
code errors. Missing paperwork.
```

### The Specific Documentation Chain CGM Requires

Every CGM claim requires all of the following to survive Medicare review:

```
CGM CLAIM DOCUMENTATION CHAIN
────────────────────────────────────────────────────────────────────

  INITIAL ORDER (one-time):
  ✓  Written Order Prior to Delivery (WOPD)
  ✓  Face-to-face practitioner visit WITHIN 6 months before order
  ✓  Diagnosis documentation (diabetes type, insulin use)
  ✓  Treating practitioner NPI — active, enrolled, correct
  ✓  Standard Written Order (SWO) with required elements
  ✓  Prior Authorization (required for all CGMs since Sept. 1, 2024)

  REFILL / CONTINUED COVERAGE (every 6 months):
  ✓  In-person or Medicare-approved telehealth visit with practitioner
  ✓  Documentation of patient adherence to CGM regimen
  ✓  Documentation of diabetes treatment plan review
  ✓  Renewed prescription if prescriber has changed
  ✓  Confirm NPI is still valid/active at time of claim

  SUPPLIER-SPECIFIC:
  ✓  Patient eligibility confirmed
  ✓  Prior auth obtained and current
  ✓  Correct HCPCS code for device model
  ✓  Quantity within allowable per billing period
  ✓  No duplicate claim for same billing period

────────────────────────────────────────────────────────────────────
Every item above is a potential denial trigger. The supplier
is responsible for assembling this chain — but most of the
information originates with people who are NOT the supplier.
```

### The 6-Month Visit Problem

The Medicare 6-month visit requirement for continued CGM coverage is, in
practice, the single largest source of preventable CGM denials for ongoing
patients. Here is why:

- The requirement lives in the physician's schedule, not the supplier's workflow
- Physicians do not automatically notify the supplier when a visit has or hasn't
  occurred
- The supplier ships a refill order, the claim goes in, and weeks later it is
  denied because the visit that was supposed to happen in month 5 actually
  happened in month 7 — or did not happen at all
- The patient has already been using the CGM supplies. Stopping them mid-cycle
  is a clinical safety issue.

**Signal CGM directly addresses this gap.** The coverage clock flags the
upcoming 6-month visit window *before* the refill order ships, giving the
supplier enough lead time to confirm with the prescriber's office.

---

## 5. The Hidden Cost: Free Product and Write-Offs

When a claim denies and a patient genuinely needs CGM supplies to manage
insulin-dependent or otherwise CGM-qualifying diabetes, suppliers face a
clinical and ethical bind that has a direct dollar cost:

### The Continuity of Care Obligation

Medicare billing rules explicitly state: *"If a Medicare beneficiary requires
additional items during the billing period, the DME supplier must provide them
at no charge to the beneficiary or to the Medicare program."*

This means that if a supplier ships CGM sensors in month 6 and the claim
subsequently denies because the 6-month physician visit was not documented,
**the supplier cannot go back and charge the patient** — they absorb the cost.

```
COST EXPOSURE MODEL — SINGLE DENIED CGM REFILL ORDER
────────────────────────────────────────────────────────────────────

  Typical monthly CGM supply order:
  ┌──────────────────────────────────────┬──────────────┐
  │ CGM sensors (1 month supply)         │ ~$150–$250   │
  │ Transmitter (amortized)              │ ~$50–$75     │
  │ Delivery + handling                  │ ~$15–$25     │
  │ Billing staff time (pre-denial)      │ ~$20–$35     │
  │                                      ├──────────────┤
  │ TOTAL cost at time of delivery       │ ~$235–$385   │
  └──────────────────────────────────────┴──────────────┘

  On denial:
  ┌──────────────────────────────────────┬──────────────┐
  │ Appeal preparation (staff time)      │ ~$25–$118    │
  │ Continuity product (if needed)       │ ~$150–$250   │
  │ Write-off on denied order            │ ~$235–$385   │
  │                                      ├──────────────┤
  │ TOTAL exposure per denied order      │ ~$410–$753   │
  └──────────────────────────────────────┴──────────────┘

  Supplier billing 500 CGM patients/month at a 25% improper
  payment rate = 125 at-risk orders/month = $51,250–$94,125
  in monthly exposure.

────────────────────────────────────────────────────────────────────
At a 25.2% CGM improper payment rate, a mid-size supplier
is essentially running a charity program for one in four
CGM patients — involuntarily.
```

The phrase "free product" is not hyperbole. Suppliers regularly continue
shipping CGM supplies to patients mid-appeal, mid-payer-review, and even after
initial denials, because:

1. The patient is insulin-dependent and cannot safely gap their CGM use
2. Stopping shipment triggers patient complaints and potential HIPAA/ADA issues
3. Restarting a stopped CGM patient requires a new order cycle — more cost

This dynamic does not exist in pharmacy. A pharmacy simply declines to fill
a prescription if insurance does not pay. DMEPOS suppliers often cannot do that
with a patient who is actively managing insulin.

---

## 6. Payment Model Disruption: CGM Goes Rental

### The Old Model (Pre-2028)

Under the traditional Medicare DME benefit structure:
- **CGM receivers**: One-time purchase payment (supplier gets paid once, patient
  owns the device after the initial claim)
- **Insulin pumps**: Capped rental (Medicare pays monthly for 13 months, then
  the beneficiary owns the device)
- **CGM sensors/supplies**: Billed monthly as a "supply allowance"

### The New Model (Effective 2028)

CMS finalized in the November 2025 DMEPOS CBP Final Rule a fundamental
reclassification:

> *CMS finalizes reclassifying all continuous glucose monitors and insulin
> infusion pumps under the **frequent and substantial servicing** payment
> category, to be paid on a **monthly rental basis** under the DMEPOS
> competitive bidding program.*

```
CGM PAYMENT MODEL: BEFORE AND AFTER
────────────────────────────────────────────────────────────────────

  BEFORE 2028:
  Month 0  │ [$$$] One-time device purchase claim → Medicare pays once
  Month 1  │ [$] Monthly supply claim
  Month 2  │ [$] Monthly supply claim
  ...
  Month 12 │ [$] Monthly supply claim
             Patient owns device outright at some point

  AFTER 2028 (Competitive Bidding Contracts):
  Month 0  │ [$] Monthly rental claim (device + supplies bundled)
  Month 1  │ [$] Monthly rental claim
  Month 2  │ [$] Monthly rental claim
  ...
             Patient never "owns" device — can upgrade technology more
             frequently, but supplier carries perpetual billing relationship

────────────────────────────────────────────────────────────────────
The shift to rental increases monthly billing volume and
complexity but also means more recurring denial opportunities
at each monthly claim cycle.

CMS rationale: CGM technology changes too fast for a 5-year
ownership model. Patient benefit is flexibility to upgrade.
Industry objection: Administratively complex; compresses margins
further when combined with CB rate reductions.
────────────────────────────────────────────────────────────────────
```

### What This Means for Suppliers

The rental model creates **12 individual claim events per year per patient**
where the old model had fewer high-value events. Each monthly rental claim
carries its own documentation window, its own prior auth cycle, and its own
denial risk. For a supplier managing 500 CGM patients, this is potentially
6,000 individual billing cycles per year — each one a potential denial if the
6-month visit isn't confirmed, the PA isn't current, or the NPI has changed.

**This multiplies the value of Signal CGM's worklist by a factor tied to monthly
billing frequency.**

## 7. The UHC / Synapse Health Wrinkle

In a development that has fundamentally altered the managed care landscape for
DME suppliers, UnitedHealthcare — the largest Medicare Advantage insurer in the
country — has been systematically transferring DME order management to a
third-party intermediary called **Synapse Health** since 2024.

### What Synapse Health Is

Synapse Health is not a payer and not a traditional pharmacy benefit manager.
It functions as a **capitated DME management vendor** — UHC enters into a
capitated arrangement with Synapse, which then manages order routing, network
credentialing, and fulfillment logistics for standard DME items for UHC
Medicare Advantage members.

### The Rollout Timeline

```
UHC / SYNAPSE HEALTH GEOGRAPHIC ROLLOUT
────────────────────────────────────────────────────────────────────

  2024        │ Initial pilots: Georgia (C-SNP), North Carolina (HMO/PPO)
              │

  Oct 1, 2025 │ HMO/PPO expansion:
              │   Illinois, Indiana, Kentucky, Michigan, Ohio, West Virginia
              │ C-SNP: Illinois added
              │
  Apr 1, 2026 │ HMO/PPO expansion:
  (NOW LIVE)  │   Arkansas, Iowa, Kansas, Minnesota, Missouri, Nebraska,
              │   North Dakota, Oklahoma, South Dakota, Wisconsin
              │ C-SNP expansion:
              │   Indiana, Iowa, Kansas, Kentucky, Michigan, Minnesota,
              │   North Carolina, North Dakota, Ohio, Oklahoma, Wisconsin
              │ D-SNP:
              │   North Dakota, South Dakota, West Virginia
              │
  Future      │ Additional states expected — pattern suggests national
              │ rollout is the strategic endpoint

────────────────────────────────────────────────────────────────────
Suppliers must join the Synapse Health network to continue
serving UHC MA members in these states. Non-enrolled
suppliers cannot receive orders for covered UHC MA members.
────────────────────────────────────────────────────────────────────
```

### What This Means for a DMEPOS Supplier

1. **Network credentialing is now layered.** To serve a UHC Medicare Advantage
   member, a supplier must be credentialed with UHC *and* separately enrolled
   with Synapse Health. Non-enrollment = lost patient.

2. **Reimbursement rates are set by Synapse's capitated contract with UHC,**
   not negotiated directly between supplier and UHC. Suppliers accept Synapse
   terms or exit the UHC MA market segment.

3. **Order workflow changes.** Orders no longer come through UHC's standard
   channels — they route through Synapse's platform (mydme@synapsehealth.com,
   1.888.336.9363). Suppliers who haven't updated their intake workflow will
   experience order processing failures.

4. **Geographic expansion is ongoing.** A supplier who is compliant today may
   have a new compliance requirement with each quarterly expansion.

5. **UHC MA is not a niche book.** UHC is the largest Medicare Advantage
   insurer. For many small and mid-size DME suppliers, UHC MA patients represent
   20–40% of their CGM patient population. Disruption to this channel is a
   material revenue risk.

```
SYNAPSE HEALTH IMPACT DIAGRAM
────────────────────────────────────────────────────────────────────

  BEFORE:
  Patient → Prescriber → [UHC approval] → DMEPOS Supplier → Ship

  AFTER (Synapse states):
  Patient → Prescriber → [UHC] → [Synapse Health routing] →
    └── Is supplier in Synapse network?
          YES: Order routed → DMEPOS Supplier → Ship
          NO:  Order routed → Different supplier → Patient lost

────────────────────────────────────────────────────────────────────
UHC paused implementation in NC and GA briefly in early 2025
due to supplier pushback, then resumed. The program has not
been rescinded — it has only expanded since the pause.
────────────────────────────────────────────────────────────────────
```

The Synapse wrinkle is separate from — and in addition to — the traditional
PA/documentation denial risk. It is a **patient access gatekeeping mechanism**
that operates before the claim is even submitted.

---

## 8. Systematic Squeeze: Are Small Suppliers Being Pushed Out?

The evidence is consistent: the structural environment for small and independent
DMEPOS suppliers has deteriorated materially over the last decade, and the
compression is accelerating in 2026.

### The Compression Forces

```
PRESSURE VECTORS ON SMALL DMEPOS SUPPLIERS
────────────────────────────────────────────────────────────────────

  MARGIN COMPRESSION
  ──────────────────
  Competitive Bidding (CB) rate reductions → Below-cost bids required
  to win CB contracts. Earlier CB rounds caused widespread closures.

  CB 2028: CGMs, insulin pumps, OTS braces, ostomy, urological all
  included. Bidding window opens late Summer/Fall 2026. Margins will
  compress further for contract winners; losers exit the market.

  DOCUMENTATION BURDEN
  ────────────────────
  PA required for all CGMs since Sept. 1, 2024.
  Prior authorization expansion effective April 13, 2026.
  Annual accreditation surveys now required (previously every 3 years).
  36-month ownership change restrictions added in 2026.

  Each new compliance layer costs staff time that small suppliers
  absorb at a higher per-patient rate than large ones.

  PAYER RESTRUCTURING
  ───────────────────
  UHC/Synapse model effectively requires dual-network credentialing.
  Other large MA plans watching UHC's model closely.

  ENROLLMENT CONTROLS
  ───────────────────
  CMS nationwide Medicare DMEPOS enrollment moratorium: Feb. 27, 2026.
  Florida Medicaid DMEPOS moratorium: March 20, 2026.
  Explicitly framed as a "fraud crackdown."
  Practical effect: New entrants blocked; consolidation accelerates.

────────────────────────────────────────────────────────────────────
```

### Supplier Count Trajectory

```
THE ATTRITION MATH
────────────────────────────────────────────────────────────────────

  Traditional HME locations: ~13,000 (2013) → ~8,005 (2024)
  Net loss over 10 years: ~5,000 supplier locations
  Rate: ~500 supplier locations per year

  Post-CB Round 2021 + PA expansion + Synapse + 2026 moratoria:
  Rate is likely accelerating, not stabilizing.

  Who exits first?
  ┌─────────────────────────────────────────────────────────────┐
  │ Small suppliers (<$3.5M revenue)                            │
  │   → Cannot absorb CB bid bond requirements ($50K per CBA)   │
  │   → Cannot staff PA workflows at competitive cost           │
  │   → Cannot complete Synapse credentialing without IT staff  │
  │   → Cannot survive a 3–5 month denial + appeal cycle        │
  │                                                             │
  │ Mid-size suppliers ($3.5M–$20M revenue)                     │
  │   → Under margin pressure but have scale to adapt           │
  │   → Often the Signal CGM buyer profile                      │
  │                                                             │
  │ Large regional / national suppliers                         │
  │   → Win CB contracts, absorb Synapse requirements with ease │
  │   → Consolidators — acquiring smaller suppliers' books      │
  └─────────────────────────────────────────────────────────────┘

────────────────────────────────────────────────────────────────────
The US healthcare system is not killing DMEPOS suppliers
directly — it is creating conditions where only those with
scale survive, which is functionally equivalent for small
operators.
────────────────────────────────────────────────────────────────────
```

### The Story the Numbers Tell

The DMEPOS sector is experiencing what might be called a **regulatory ratchet**:
each new compliance layer is individually justifiable (PA reduces waste; CB
reduces Medicare cost; moratoria prevent fraud enrollment), but the cumulative
effect on small operators is insurmountable overhead. Large suppliers can hire
the billing staff, purchase the compliance software, and complete the network
credentialing. Small ones cannot.

The paradox is that the suppliers most likely to exit are also the ones most
likely to be providing personalized, community-level service to the patients who
need it most. CGM patients receiving supplies from a local independent supplier
— who knows them by name, calls when shipments are due, and troubleshoots
device issues — lose access to that relationship when the supplier closes.

---

## 9. Patient Outcomes: Why DMEPOS Channel Matters

The most important counterargument to the consolidation trend — and a key Signal
CGM positioning asset — is the clinical evidence on patient outcomes by sourcing
channel.

### DME Channel vs. Pharmacy: The Study

A 2024 peer-reviewed retrospective claims analysis published in *Clinical
Diabetes* (American Diabetes Association) and JMIR Diabetes compared CGM
adherence and healthcare costs for patients sourcing CGMs from DME suppliers
versus pharmacy channels.

```
CGM ADHERENCE: DME CHANNEL vs. PHARMACY CHANNEL (12-MONTH DATA)
────────────────────────────────────────────────────────────────────

  Adherence Rate at 12 Months:
  ┌──────────────────────────────────────────────────────────┐
  │                                                          │
  │  DME Channel    78% ████████████████████████████████░░  │
  │  Pharmacy       64% ██████████████████████████░░░░░░░░  │
  │                                                          │
  │  DME advantage: +14 percentage points                    │
  │  DME patients: 23% MORE likely to adhere                 │
  │                                                          │
  └──────────────────────────────────────────────────────────┘

  Healthcare Cost at 12 Months:
  DME Channel patients paid 35% LESS in overall healthcare costs
  compared to pharmacy-sourced CGM patients.

  Reinitiation Rate:
  DME-sourced patients were MORE likely to restart CGM use after
  a gap period compared to pharmacy-sourced patients.

  Physician Preference:
  73% of endocrinologists prefer DME suppliers over other
  distribution models due to superior end-user support.

────────────────────────────────────────────────────────────────────
The DME channel produces better clinical outcomes because
DME suppliers specialize in equipment management, patient
education, and ongoing support — services a pharmacy counter
cannot replicate.
────────────────────────────────────────────────────────────────────
```

### Why This Matters for Signal CGM

The patient outcome evidence is a strategic asset for DMEPOS suppliers in two
directions:

1. **Legislative / advocacy context:** DMEPOS suppliers can legitimately argue
   that policies driving them out of the market (CB margin compression, Synapse
   gatekeeping, enrollment moratoria) harm patients, not just suppliers. The
   data supports this.

2. **Signal CGM ROI argument:** A supplier who uses Signal CGM to prevent
   coverage gaps keeps patients on their CGM continuity, which produces the
   adherence advantage. Helping a patient stay covered is not just a billing
   optimization — it is a clinical outcome driver.

## 10. The Regulatory Stack — 2026 Urgency Drivers

```
ACTIVE REGULATORY PRESSURES AS OF APRIL 2026
────────────────────────────────────────────────────────────────────

  LIVE NOW
  ────────
  ● PA Required for ALL CGMs (since Sept. 1, 2024)
    Every initial CGM order must have prior authorization.
    New supply codes (A4238) added to Master List Jan. 2026.

  ● PA Expansion — April 13, 2026 (this month)
    7 additional HCPCS codes added to required prior auth list.
    New exemption process: suppliers with ≥10 requests and
    ≥90% provisional affirmation rate may qualify for exemption.
    First exemption cycle begins June 1, 2026.

  ● Nationwide Medicare DMEPOS Enrollment Moratorium (Feb. 27, 2026)
    No new supplier enrollments for 6 months.
    New/change-of-majority-ownership applications denied.
    Incumbent suppliers have protected market position —
    and rising per-patient management burden.

  ● Florida Medicaid Moratorium (March 20, 2026)
    6-month moratorium on new Medicaid DMEPOS supplier enrollment.
    Incumbent Florida suppliers face rising patient load.

  ● Annual Accreditation Surveys (effective Jan. 1, 2026)
    Previously required every 3 years; now annual.
    36-month majority ownership change restrictions added.
    Administrative overhead up across the board.

  ● UHC/Synapse Health Expansion (April 1, 2026)
    10 additional states now require Synapse enrollment.
    Suppliers not in network lose access to UHC MA patients.

  COMING
  ──────
  ● CB 2028 Bidding Window (opens late Summer/Fall 2026)
    CGMs, insulin pumps, ostomy, urological, OTS braces included.
    Suppliers must bid competitively or exit CB contract areas.
    18–24 months to prepare cost structures and denial workflows
    before rates compress further.

  ● CGM Monthly Rental Reclassification (effective Jan. 1, 2028)
    All CGMs move to "frequent and substantial servicing" category.
    Monthly billing replaces purchase-based model.
    12× annual claim events per patient vs. current model.

────────────────────────────────────────────────────────────────────
Every item above increases the documentation burden, the billing
complexity, or the margin pressure on DMEPOS suppliers — and
increases the value of a tool that automates coverage tracking.
────────────────────────────────────────────────────────────────────

## 11. The Workload Impact Model

This is the core Signal CGM value visualization for sales and discovery calls.

```
SUPPLIER STAFF TIME: REACTIVE vs. PROACTIVE WORKFLOW
────────────────────────────────────────────────────────────────────

  Staff Hours/Week
  │
  │  REACTIVE (without Signal CGM)
  High │
       │ ██████████████████
       │ ████████████████████████
       │ ██████████████████████████████
       │ █████████████████████████████████████
       │ ████████████████████████████████████████████
  ─────┼────────────────────────────────────────────────────▶ Month
       │ ↑ Appeals backlog grows as denials compound
       │   Each unresolved denial breeds the next
       │   Staff is reactive — putting out fires, not preventing them

  PROACTIVE (with Signal CGM)
  │
  Low  │ ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓
       │  Flat, predictable outreach workload
       │  Staff works off a sorted worklist each morning
       │  Highest-urgency patients at the top
       │  Outreach happens before the claim, not after the denial

────────────────────────────────────────────────────────────────────

  THE TWO CURVES (Discovery Call Visual)

  Staff Time
  │\
  │ \      CURVE A: Reactive appeals/denials workload
  │  \     Starts HIGH — every backlogged denial requires staff time
  │   \    Trends DOWN as proactive management takes hold
  │    \
  │     \  ← Crossover = ROI moment (typically Month 3–5)
  │      \_____________________________________
  │
  │      ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓
  │      CURVE B: Proactive Signal CGM outreach workload
  │      Starts MANAGEABLE — sorted worklist, predictable volume
  │      Stays FLAT — does not grow with patient count
  │
  └──────────────────────────────────────────────▶ Month
       1    2    3    4    5    6    7    8    9   10  11  12

────────────────────────────────────────────────────────────────────
The crossover is the ROI moment to anchor on discovery calls.
Signal CGM does not eliminate work. It restructures it —
from uncontrolled reactive fire-fighting to controlled,
predictable outreach.

## 12. Contrary Opinions — The Other Side of the Story

A fair research document must include the legitimate criticisms of the DMEPOS
sector. These are real, documented, and used by payers and regulators to
justify the compliance burden suppliers carry.

### The Fraud Record Is Real

The OIG and DOJ have documented a consistent pattern of DMEPOS fraud over
decades, and it is not trivial:

| Enforcement Action | Details |
|--------------------|---------|
| OIG improper payments | $22.7M in improper payments over 7 years for DME during inpatient stays |
| Overpayment (2015–2017) | $34M in supplier overpayments found in audit |
| Continued overpayment | $4.5M overpayments found in 2020–2024 follow-up audit |
| Annual Medicare DME spend | $7B+ annually — the size of the target |
| 2026 moratorium framing | CMS explicitly frames as "major crackdown on fraud" |

### The Specific Fraud Patterns That Taint the Sector

**Billing for items never delivered.** Some suppliers have submitted Medicare
claims for DME that was never actually provided to the beneficiary, or submitted
bills without the patient's knowledge or consent.

**Kickback arrangements.** Some providers accepted kickbacks from suppliers to
prescribe DMEPOS items that were not medically necessary. This polluted the
prescriber-supplier relationship that honest suppliers depend on.

**Identity theft and patient data exploitation.** In some cases, patient
information was used to open fraudulent DME accounts entirely without the
patient's involvement.

**Credential farming.** Newly enrolled suppliers with no actual patient
population billed extensively and then folded — a pattern that drove the
enrollment moratorium model.

### The Counterargument (Structural, Not Exculpatory)

The fraud that exists in DMEPOS is real but concentrated. It is predominantly
perpetrated by:
- **Shell companies** with no operational patient base
- **Organized fraud rings** exploiting the lag time between claim submission
  and audit detection
- **Referral kickback networks** involving physicians and marketers, not
  frontline clinical suppliers

Legitimate, established DMEPOS suppliers — particularly those serving
real patient populations with real clinical needs like CGM — bear the
compliance cost of the fraud perpetrated by bad actors they have nothing to do
with. The documentation requirements, prior authorization rules, enrollment
scrutiny, and audit risk that legitimate suppliers navigate daily exist, in
large part, because of fraud committed by entities that were never legitimate
suppliers in the first place.

### Legitimate Criticism: Documentation Burden as Competitive Barrier

A more structural criticism comes from health economists and patient advocates:
the complexity of DMEPOS billing documentation has become so high that it now
functions as a barrier to *legitimate* competition, not just fraud prevention.
Suppliers who cannot afford billing staff or compliance software exit the
market — not because they are fraudulent, but because compliance overhead
consumes margin. The result is consolidation toward large operators who can
absorb the overhead, which is arguably the opposite of the competitive outcome
policymakers claim to want.

### The Other Side of "Patient Outcomes"

While the DME channel does show superior CGM adherence (Section 9), critics
note:

- **Selection bias:** DME-sourced CGM patients may be more engaged in their
  care to begin with (they navigated the DME intake process vs. a simple
  pharmacy pickup)
- **Pharmacy channel improvements:** Retail pharmacies have invested heavily
  in diabetes services and clinical pharmacist programs; the 2024 data may
  not fully reflect these improvements
- **Consolidation quality risk:** The DME channel advantage is attributed to
  personalized support from specialized staff — but as consolidation replaces
  local suppliers with national operators, that personalization advantage may
  erode, making the channel comparison less favorable over time

## 13. Signal CGM Positioning Summary

```
SIGNAL CGM VALUE STACK
────────────────────────────────────────────────────────────────────

  PROBLEM (proven, data-backed)
  ├── CGM improper payment rate: 25.2% / $278.5M annually
  ├── 94.2% of those failures: documentation errors, not fraud
  ├── Supplier bears full cost on already-delivered product
  ├── 6-month visit requirement: predictable, trackable, preventable
  ├── Monthly rental model (2028): 12× annual billing events = 12×
  │   denial opportunities per patient per year
  └── UHC/Synapse: new credentialing layer creating patient access risk

  SOLUTION (Level 1 scope)
  ├── Coverage clock per patient: tracks wear-day rules by device/payer
  ├── 6-month visit flag: surfaces BEFORE refill ships, not after deny
  ├── Daily sorted worklist: OUT_OF_COVERAGE, VISIT_DUE, REFILL_WINDOW
  ├── Minimal PHI surface: patient_id only, no names/SSNs/DOBs
  └── Self-hosted: data never leaves supplier's environment

  URGENCY (why act now, not later)
  ├── PA expansion: live April 13, 2026
  ├── CB 2028 bidding window: opens late Summer/Fall 2026
  ├── Enrollment moratoria: incumbents have protected position but
  │   rising per-patient burden — tools are the only scale lever
  └── Monthly rental model coming: front-load compliance infrastructure
      before billing complexity doubles

  TARGET BUYER
  ├── Mid-size supplier: 200–2,000 CGM patients/month
  ├── Currently managing coverage in spreadsheets or Brightree fields
  └── Feels the denial problem but doesn't have a systematic fix

## 14. Verified Stat Index — May 2026

*Stat verification completed May 23, 2026. Use this table before citing any Signal-related statistic. The "usable" column reflects what is citable with a direct source URL.*

### What Is Verified With Direct Citations

| Stat | Source | What It Measures | Usable for Signal |
|------|--------|-----------------|-------------------|
| 32.8% error rate on glucose monitor claims | CERT 2019 annual report | Random sample of PAID claims reviewed post-payment | Yes — locked stat. "Nearly 1 in 3." |
| 68.6% of those errors from insufficient documentation | CERT 2019 annual report | Share of error-rate claims with doc problems | Yes — locked. "Over two-thirds from docs." |
| 25.2% CGM improper payment rate | CMS 2024 MLN compliance page (direct URL) | Claims paid that had documentation problems — post-payment audit exposure | Yes — audit exposure narrative |
| 67.6% absent documentation | CMS 2024 MLN compliance page (direct URL) | Share of those improper payments with no docs at all | Yes — use for whitepaper/gate framing |
| **30.86% pre-pay review error rate** | **CGS MAC Jurisdiction B Q2 2024** | **Claims reviewed before or at payment — near submission** | **Best source for denial prevention pitch** |
| 18.52% TPE error rate | MAC B/C 2025 | Claims reviewed at audit | Strong supporting evidence |
| $1.9B DMEPOS improper payments FY2024 | OIG (URL exists) | All DMEPOS categories, not CGM specifically | Market context only |
| DMEPOS 22.5% vs 7.38% overall Medicare | Post-payment comparison | DMEPOS vs. all Medicare improper payment rate | Market context |
| 63.9% MA appeal success at Level 2 | KFF 2024 (direct URL) | Medicare Advantage only — not FFS | MA context only, qualify if used |

### What Is Derived or Not Directly Citable

| Stat | Problem | What to Use Instead |
|------|---------|-------------------|
| "94.2% of CGM denials are documentation failures" | Derived sum of two CMS MLN line items — not stated directly by CMS | CERT 2019: "over two-thirds from docs" |
| "35–45% of CGM claims denied" | Scenario-based, not universal | "First-pass denial rates vary significantly by supplier documentation maturity" |
| "63% of denied CGM claims are written off permanently" | Derived model, not citable | Do not use as a standalone stat |

### Why CGS MAC Pre-Pay Wins for Signal's Pitch

The CGS Jurisdiction B pre-pay review measures claims being stopped and reviewed near submission — not years later in a post-payment audit. Every top-10 denial reason in the CGS data is a documentation failure. This is the only publicly available source that measures documentation risk at the point Signal addresses it: before supplies ship and before the claim is filed.

The CERT and CMS MLN stats measure what happened after the fact. The CGS pre-pay stat measures the same problem Signal solves, at the same point in the workflow Signal operates.

**Use CGS MAC pre-pay for denial prevention framing. Use CERT 2019 for LinkedIn and public-facing stats.**
