TL;DR: The Centers for Medicare & Medicaid Services modified NCD 368 for gender reassignment surgery, effective January 9, 2026. No national coverage exists — your MAC makes the call, case by case.
This update to NCD 368 Medicare policy confirms that gender reassignment surgery for Medicare beneficiaries with gender dysphoria carries no national covered or non-covered designation. The Centers for Medicare & Medicaid Services originally reached this determination on August 30, 2016, and this 2026 review leaves that framework intact. No specific CPT or HCPCS codes are listed in the policy. Coverage decisions fall entirely to your local Medicare Administrative Contractor.

CMS Gender Reassignment Surgery Coverage Criteria and Medical Necessity Requirements 2026
Here is the core reality of this policy: CMS has no nationally covered indications and no nationally non-covered indications for gender reassignment surgery. That is not a gap in the policy document — that is the policy.
Under NCD 368, the CMS gender reassignment surgery coverage policy explicitly defers to local Medicare Administrative Contractors. Each MAC evaluates claims under Section 1862(a)(1)(A) of the Social Security Act, which is the standard medical necessity requirement that applies across Medicare. What qualifies as medically necessary in one MAC jurisdiction may not qualify in another.
This matters for your billing team because there is no single answer to "is this covered?" The answer depends entirely on which MAC processes your claims. If you bill in a region covered by Palmetto GBA, Noridian, or any other MAC, you need that contractor's local coverage determination — not this NCD.
Prior authorization requirements, documentation standards, and medical necessity criteria all vary by MAC. NCD 368 does not establish a federal floor. It establishes a vacuum, and the MACs fill it differently.
If you are billing gender reassignment surgery billing for Medicare patients and you have not pulled your MAC's LCD on this topic, stop and do that first. The reimbursement outcome of your claims depends on it.
CMS Gender Reassignment Surgery Exclusions and Non-Covered Indications
This section is where NCD 368 gets genuinely unusual. Most NCDs include at least some nationally non-covered indications — procedures CMS has reviewed and explicitly excluded from Medicare coverage nationwide.
NCD 368 lists none. There are no nationally non-covered indications.
That sounds better than it is. The absence of a national non-coverage determination does not mean these procedures are broadly covered. It means CMS declined to make a federal decision either way. Some billing teams read "no non-covered indications" as a green light. It is not.
What it means in practice: your MAC can cover, restrict, or deny these services entirely within its jurisdiction, and there is no national policy to appeal to when a denial comes back. The coverage policy gives you nothing to cite in your favor at the federal level.
If your MAC has not issued a local coverage determination on gender reassignment surgery, claims go to case-by-case review. That is unpredictable territory. Document medical necessity thoroughly on every claim — more than you think you need.

| Nationally Covered Indications | N/A | N/A | CMS made no national coverage decision |

CMS Gender Reassignment Surgery Billing Guidelines and Action Items 2026
The effective date for this modified policy is January 9, 2026. Here is what your billing team should do now.
| # | Action Item |
|---|---|
| 1 | Pull your MAC's current LCD or coverage article on gender reassignment surgery. Do this before billing any procedure in this category. Your MAC's position — not NCD 368 — determines whether your claim pays or denies. Find your MAC at the CMS website and search their coverage database directly. |
| 2 | Document medical necessity at the claim level as if no coverage policy exists in your favor. Because at the national level, none does. Use the treating physician's clinical notes, DSM-5 diagnosis documentation, any letters of support, and prior treatment history. Make your medical necessity argument complete before the claim leaves your system. |
| 3 | Check whether your MAC requires prior authorization for these procedures. NCD 368 does not address prior authorization. Your MAC might. Call the provider services line or check the MAC's published billing guidelines for surgical procedures tied to gender dysphoria diagnoses. |
| 4 | Flag any pending claims for gender reassignment procedures and confirm they align with current MAC guidance. If your MAC updated its LCD in the past 12 months, prior claim submissions may not reflect the current standard. Audit your open claims against the MAC's current documentation requirements. |
| 5 | Build a denial response process specific to this policy. Because NCD 368 provides no national authority to cite, claim denials in this category require MAC-level appeals. Know your MAC's appeals timeline, the correct appeal level for medical necessity denials, and what clinical documentation the reviewer needs to overturn a denial. |
| 6 | Loop in your compliance officer before billing complex or high-cost cases. The lack of a national coverage determination creates legal and billing ambiguity. If you are unsure how your MAC's local coverage determination applies to a specific patient or procedure, get your compliance officer involved before the claim goes out — not after the denial. |
| 7 | Do not rely on historical approval patterns as current coverage guidance. MAC coverage positions on gender reassignment surgery have shifted in multiple jurisdictions over the past several years. A claim that paid in 2023 under the same MAC may face different scrutiny today. Verify current guidance directly. |
| 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 Gender Reassignment Surgery Under NCD 368
Covered CPT Codes
NCD 368 does not list any specific CPT or HCPCS codes. The policy makes no code-level coverage decisions.
Not Covered / Experimental Codes
NCD 368 does not designate any specific codes as non-covered or experimental at the national level.
Key ICD-10-CM Diagnosis Codes
NCD 368 does not list specific ICD-10-CM codes. Diagnosis code selection for gender dysphoria — typically from the F64.x category — should align with your MAC's LCD requirements and the treating physician's documented diagnosis.
What this means for your charge capture: There is no code-level guidance in this policy. Your charge capture setup, medical necessity mapping, and diagnosis-to-procedure linking all need to be built from your MAC's local coverage determination, not from NCD 368. If your MAC has published an LCD, that document is your actual billing reference. If your MAC has not published an LCD, case-by-case review applies, and your documentation needs to be airtight.
This is one of the few NCDs where the policy document itself gives billing teams almost nothing operationally useful. The real work is at the MAC level.
