TL;DR: CMS modified NCD 129 governing Medicare coverage for the treatment of actinic keratosis, effective March 7, 2026. Here's what billing teams need to know.
The Centers for Medicare & Medicaid Services updated NCD 129 — the National Coverage Determination governing Medicare coverage for actinic keratosis (AK) destruction. The coverage policy itself is favorable: Medicare covers AK destruction without restrictions based on lesion or patient characteristics, for services performed on and after November 26, 2001. This modification formalizes and clarifies that standing policy under NCD 129 in the CMS Medicare system. No specific CPT or HCPCS codes are enumerated in this policy document, which means your billing team will need to cross-reference current claims processing instructions and applicable local coverage determinations to confirm code-level guidance.

CMS Actinic Keratosis Coverage Criteria and Medical Necessity Requirements 2026
NCD 129 sets a broad standard. Medicare covers the destruction of actinic keratoses without restrictions based on lesion characteristics or patient characteristics. That's the CMS actinic keratosis coverage policy in plain terms.
The effective date for this coverage standard is November 26, 2001 — this modification on March 7, 2026 updates the policy record without narrowing that coverage. The practical effect is that you don't need to document specific lesion size, number, location, or histologic grade to establish medical necessity for AK destruction under this NCD.
That said, "no restrictions" at the NCD level doesn't mean your Medicare Administrative Contractor can't impose tighter standards through a local coverage determination. Many MACs have active LCDs that add documentation requirements on top of NCD 129. If your MAC has an LCD for AK destruction, those local rules govern your claims. Check your MAC's LCD portal now — before the effective date of March 7, 2026 — to confirm what's required in your region.
Medical necessity documentation still matters even when coverage is unrestricted. Your records should reflect that the provider evaluated the lesion, confirmed the AK diagnosis, and selected an appropriate treatment. The policy notes clinicians should base treatment selection on the patient's medical history, the lesion's characteristics, and the patient's preference. Document all three. An audit or claim denial is much harder to fight when that clinical rationale isn't in the chart.
Prior authorization is not mentioned as a requirement under NCD 129 for standard AK destruction. However, if your practice performs less common AK treatments — dermabrasion, chemical peels, laser therapy, or photodynamic therapy — check with your MAC and any applicable commercial payers. Those modalities carry more scrutiny and may require prior authorization depending on the payer and clinical context.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Destruction of actinic keratoses (any lesion, any patient) | Covered | Not specified in NCD 129 — see MAC LCD and claims processing instructions | No restrictions on lesion or patient characteristics; effective November 26, 2001 |
| Cryosurgery with liquid nitrogen for AKs | Covered | Not specified in NCD 129 | Commonly performed; document clinical rationale |
| Topical drug therapy for AKs | Covered | Not specified in NCD 129 | Confirm reimbursement under applicable drug benefit category |
| Curettage for AKs | Covered | Not specified in NCD 129 | Document treatment selection rationale |
| Dermabrasion for AKs | Covered (less common — verify LCD) | Not specified in NCD 129 | Less commonly performed; MAC LCD may impose additional criteria |
| Excision for AKs | Covered (less common — verify LCD) | Not specified in NCD 129 | Less commonly performed; confirm medical necessity documentation |
| Chemical peels for AKs | Covered (less common — verify LCD) | Not specified in NCD 129 | Less commonly performed; high scrutiny — check for prior auth requirements |
| Laser therapy for AKs | Covered (less common — verify LCD) | Not specified in NCD 129 | Less commonly performed; verify LCD and document thoroughly |
| Photodynamic therapy for AKs | Covered (less common — verify LCD) | Not specified in NCD 129 | Less commonly performed; check MAC LCD and prior auth |
| Observation/watchful waiting for AKs | Not a destruction service — not a covered "treatment" under NCD 129 | N/A | Observation is an alternative approach, not a billable destruction service under this NCD |
CMS Actinic Keratosis Billing Guidelines and Action Items 2026
NCD 129 is good news for your reimbursement picture — broad, unrestricted coverage is a billing team's friend. But "unrestricted" doesn't mean "undocumented." Here's what to do before and after the effective date of March 7, 2026.
| # | Action Item |
|---|---|
| 1 | Pull your MAC's LCD for AK destruction right now. NCD 129 sets the floor — no restrictions — but your Medicare Administrative Contractor can layer local requirements on top. Go to your MAC's website, search for any active LCD covering destruction of benign or premalignant skin lesions, and compare those documentation requirements to your current workflow. If there's a gap, close it before March 7, 2026. |
| 2 | Confirm the correct CPT codes with your MAC's claims processing instructions. NCD 129 does not list specific CPT or HCPCS codes. That's the most operationally important thing to understand about this policy. Pull the cross-referenced claims processing instructions from CMS directly, and verify with your MAC which destruction codes apply to AK services. Common destruction codes exist in the CPT surgery section, but confirming the exact codes your MAC expects is non-negotiable for clean claim submission. |
| 3 | Update your documentation templates to reflect NCD 129's three-factor treatment rationale. The policy is explicit: treatment selection should be based on patient medical history, lesion characteristics, and patient preference. Build those three elements into your encounter note template. That documentation supports medical necessity and protects you in a post-payment audit. |
| 4 | Audit recent AK destruction claims for compliant coding. Pull three to six months of AK-related claims. Confirm the diagnosis codes used are accurate, that the service codes match the actual destruction method performed, and that documentation supports the claim. If you find inconsistencies, correct them now. A proactive audit before March 7, 2026 is far less painful than a retrospective one triggered by a claim denial. |
| 5 | Flag less-common AK treatments for secondary review. Dermabrasion, excision, chemical peels, laser therapy, and photodynamic therapy are covered under NCD 129 — but the policy itself calls them "less commonly performed." That language is a signal. These services draw more scrutiny from MACs and commercial payers alike. For each of these modalities, confirm your MAC's LCD position, check whether prior authorization applies under any relevant plan, and make sure your documentation is airtight before billing. |
| 6 | Talk to your compliance officer if your practice bills photodynamic therapy for AKs. Photodynamic therapy (PDT) for AKs exists in a gray zone across payers — covered under NCD 129 for Medicare, but frequently questioned at the MAC level and often scrutinized by commercial payers. If PDT is a material part of your revenue, have your compliance officer review your current billing guidelines against the updated NCD 129 policy and applicable LCDs before the effective date. |
| 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 Actinic Keratosis Treatment Under NCD 129
NCD 129 does not enumerate specific CPT, HCPCS, or ICD-10 codes. This is a known limitation of this policy document, and it has real operational consequences for actinic keratosis billing.
What This Means for Your Billing Team
CMS directs billers to the cross-referenced claims processing instructions for code-level guidance. You need to retrieve those instructions directly from CMS or your MAC to confirm which codes are recognized under this NCD.
Do not assume a code is covered under NCD 129 simply because it describes an AK treatment. The absence of an explicit code list means your MAC's LCD — and your MAC's claims processing instructions — carry significant weight in determining which codes pass through cleanly.
Where to Find the Applicable Codes
- CMS Claims Processing Instructions: Cross-referenced in NCD 129. Pull directly from the CMS Medicare Coverage Database.
- MAC LCD: Search your MAC's policy portal for destruction of premalignant skin lesions. Most MACs with active LCDs for this service list covered CPT codes explicitly.
- CMS Medicare Fee Schedule: Once you've confirmed the applicable CPT codes through the above sources, verify reimbursement rates for your locality in the Medicare Physician Fee Schedule.
If your billing team isn't sure which CPT codes your MAC recognizes for AK destruction, call your MAC's provider relations line before March 7, 2026. This is not a step to skip — submitting claims with unsupported codes under an NCD that doesn't list codes is a fast path to claim denial and potential takebacks.
