TL;DR: The Centers for Medicare & Medicaid Services modified NCD 207, the National Coverage Determination governing Sykes Hernia Control devices, effective March 7, 2026. Here's what changes for billing teams.
CMS has reaffirmed — with this modification — that the Sykes Hernia Control device (a spring-type, U-shaped, strapless truss) gets reimbursed only at the rate of a conventional truss, not at whatever the manufacturer or supplier charges. NCD 207 falls under the Medicare benefit category for Leg, Arm, Back, and Neck Braces (orthotics). No specific CPT or HCPCS codes are listed in this policy, which creates a documentation challenge you need to get ahead of before the March 7, 2026 effective date.

| Field | Detail |

| Payer | CMS (Centers for Medicare & Medicaid Services) |
| Policy | Sykes Hernia Control |
| Policy Code | NCD 207 |
| Change Type | Modified |
| Effective Date | 2026-03-07 |
| Impact Level | Low–Medium (niche device, but reimbursement cap has real revenue exposure for DME suppliers billing above conventional truss rates) |
| Specialties Affected | DME suppliers, general surgery billing, orthotics billing |
| Key Action | Cap your billed charges for Sykes Hernia Control at the reasonable charge rate for a conventional truss — anything above that will be adjusted down by Medicare |
CMS Sykes Hernia Control Coverage Criteria and Medical Necessity Requirements 2026
The core of this CMS coverage policy is straightforward: the Sykes Hernia Control is not considered functionally superior to a conventional truss. That determination came from professional clinical review, and CMS has built it directly into NCD 207. Medical necessity for the device exists only where an ordinary truss would itself be covered — and that's a narrower window than you might expect.
Trusses in general — and the Sykes device specifically — are only appropriate for reducible hernias. If the hernia is irreducible (incarcerated or strangulated), neither the Sykes Hernia Control nor any conventional truss qualifies for Medicare reimbursement. That's not a gray area. Bill one anyway and you're looking at a claim denial.
The coverage policy does not require prior authorization for the Sykes device, but the underlying medical necessity criteria must be met and documented. The treating physician's recommendation and documentation of a reducible hernia diagnosis need to be in the record before the claim goes out.
On reimbursement: when the billed charge for the Sykes Hernia Control exceeds what's reasonable for a conventional truss treating the same condition, Medicare will base payment on the conventional truss reasonable charge — not your submitted charge. That's a hard ceiling, not a guideline. If your billing team is pricing this device at a premium over conventional truss rates, that delta is unrecoverable under this policy.
The cross-reference in NCD 207 points to the Medicare Benefit Policy Manual, Chapter 15, §130. If you're reconciling this with your own LCD or local carrier guidance, pull that chapter alongside NCD 207.
CMS Sykes Hernia Control Exclusions and Non-Covered Indications
Coverage is denied outright for trusses — including the Sykes Hernia Control — when the hernia is not reducible. Full stop.
If the Sykes device is billed in a context where a conventional truss would not be covered, the Sykes claim fails on the same grounds. The CMS billing guidelines here don't introduce a new category of coverage; they peg the device entirely to the existing conventional truss coverage rules. That means any scenario where a truss is excluded — irreducible hernias, cases lacking documented medical necessity — carries over directly to the Sykes Hernia Control.
There's no pathway under NCD 207 to bill the Sykes device as a superior or alternative technology that warrants a higher coverage tier. CMS explicitly rejected that framing.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Reducible hernia, where a conventional truss would be covered | Covered | No specific codes listed in NCD 207 | Reimbursement capped at conventional truss reasonable charge rate |
| Reducible hernia, Sykes charged substantially above conventional truss rate | Covered (adjusted) | No specific codes listed in NCD 207 | Medicare pays at conventional truss rate only; excess charge not reimbursable |
| Irreducible (incarcerated/strangulated) hernia | Not Covered | No specific codes listed in NCD 207 | Applies to Sykes Hernia Control and conventional trusses equally |
| Sykes device billed where conventional truss would not be covered | Not Covered | No specific codes listed in NCD 207 | Coverage eligibility follows conventional truss rules entirely |
CMS Sykes Hernia Control Billing Guidelines and Action Items 2026
| # | Action Item |
|---|---|
| 1 | Audit your fee schedule for the Sykes Hernia Control now, before March 7, 2026. If your DME billing team has this device priced above your local Medicare allowable for a conventional truss, that's the gap you're losing revenue on — or worse, that you'll need to refund if audited. |
| 2 | Confirm your documentation includes a reducible hernia diagnosis before submitting any claim for this device. Medical necessity documentation must establish that the hernia is reducible. A vague diagnosis code or a chart note that doesn't address reducibility won't hold up under a post-payment review. |
| 3 | Pull the physician's recommendation and make sure it's in the record. NCD 207 explicitly ties coverage to professional advice/prescription. Claims without a documented physician order are vulnerable to denial. |
| 4 | Cross-check NCD 207 against any applicable local coverage determinations (LCDs) in your MAC jurisdiction. NCD 207 sets the national floor; your MAC may have additional documentation or prior authorization requirements layered on top. Check your MAC's website before the March 7, 2026 effective date. |
| 5 | Confirm which HCPCS code your team is billing for the Sykes Hernia Control. NCD 207 doesn't list specific codes — which means your coding team needs to verify the correct HCPCS code against the DME fee schedule and confirm it maps to truss coverage. If you're not certain your code selection is correct, loop in your billing consultant or compliance officer before the effective date. |
| 6 | Train your DME billers on the reimbursement cap logic. This isn't a standard coverage denial — it's a reimbursement adjustment. The claim doesn't necessarily deny outright; it pays at the conventional truss rate. Your team needs to understand the difference so they don't waste time appealing a correct payment adjustment. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Sykes Hernia Control Under NCD 207
Covered HCPCS/CPT Codes
NCD 207 does not list specific CPT or HCPCS codes. The policy does not provide code-level assignments for the Sykes Hernia Control device or conventional trusses.
To bill correctly under this coverage policy, your billing team must identify the appropriate HCPCS code for the Sykes Hernia Control through the DMEPOS fee schedule and your MAC's guidance. Do not assume a code — confirm it. An incorrect code selection here directly affects your reimbursement calculation and your exposure to claim denial.
Key ICD-10-CM Diagnosis Codes
NCD 207 does not enumerate specific ICD-10-CM codes. However, the policy restricts coverage to reducible hernias, so your diagnosis code must reflect that. Review the ICD-10-CM options for inguinal, umbilical, and other hernia types, selecting the code that specifically indicates the hernia is reducible — not obstructed, not gangrenous.
The real issue here is that a diagnosis code for an irreducible hernia will contradict the medical necessity standard in NCD 207 and trigger a denial. Code selection has to match the clinical picture precisely.
