Summary: The Centers for Medicare & Medicaid Services modified its thermography coverage policy, effective May 15, 2026. Here's what billing teams need to know before that date.
CMS thermography coverage policy has long been one of the more straightforward non-coverage positions in Medicare — thermography is not covered. This modification doesn't reverse that position. But it's worth understanding exactly what the policy says, why CMS keeps revisiting it, and what your billing team should do to avoid claim denial on any thermography-adjacent services.
The policy does not list specific CPT or HCPCS codes in the available data. That's noted clearly below.

CMS Thermography Coverage Criteria and Medical Necessity Requirements 2026
The Centers for Medicare & Medicaid Services does not consider thermography medically necessary for any diagnostic or screening indication under Medicare. That position has been consistent for decades, and this 2026 modification does not change it.
Thermography — which uses infrared imaging to detect heat patterns in tissue — has been studied for breast cancer screening, vascular disease, and a range of other conditions. CMS has repeatedly reviewed the evidence and concluded it does not meet the standard for Medicare coverage. The clinical evidence base is not strong enough to support reimbursement.
This matters for your billing team because the conversation around thermography has gotten louder in recent years. Direct-to-consumer marketing has pushed patients toward thermography as an alternative or adjunct to mammography. When those patients have Medicare, they sometimes arrive at your practice expecting coverage. They won't get it.
The CMS coverage policy does not support prior authorization as a path to reimbursement here. There's no prior authorization process that unlocks thermography for Medicare patients — the service is excluded at the coverage level, not the authorization level. That's an important distinction. Prior auth applies when a service is covered but requires advance approval. Thermography doesn't clear the first hurdle.
CMS Thermography Exclusions and Non-Covered Indications
CMS excludes thermography across indications. This isn't a narrow exclusion for a specific body part or clinical scenario — it's a blanket non-coverage position.
The most commonly billed applications where you might encounter this:
Breast thermography. Patients sometimes present after seeing marketing that positions thermography as a "safer" or "radiation-free" alternative to mammography. Medicare does not cover it for breast screening or diagnosis.
Peripheral vascular disease assessment. Some practices use thermography to assess circulation. CMS does not cover this application either.
Musculoskeletal and pain assessment. Thermography has been marketed for evaluating pain syndromes and soft tissue injury. Again, not covered under Medicare.
Integrative and functional medicine applications. Practices offering thermography as part of a broader "wellness" workup should know that Medicare will not reimburse any component billed as thermography.
The real issue here is patient liability. If your practice offers thermography and bills it to Medicare, you'll get a claim denial. If you haven't issued an Advance Beneficiary Notice of Noncoverage (ABN) before the service, you likely can't collect from the patient either. That's a complete revenue loss.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Breast cancer screening via thermography | Not Covered | Not specified in available policy data | No prior auth pathway; ABN required to bill patient |
| Peripheral vascular disease assessment via thermography | Not Covered | Not specified in available policy data | ABN required to bill patient |
| Musculoskeletal / pain syndrome evaluation via thermography | Not Covered | Not specified in available policy data | ABN required to bill patient |
| General diagnostic thermography (any indication) | Not Covered | Not specified in available policy data | CMS position is blanket non-coverage; no covered exceptions noted |
CMS Thermography Billing Guidelines and Action Items 2026
This policy modification has a clear effective date of May 15, 2026. Your action items before that date:
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for any thermography services. If your practice has been billing thermography to Medicare — under any code — pull those claims now. Identify what's going out and how it's being coded. |
| 2 | Confirm your ABN workflow is in place before May 15, 2026. If your practice offers thermography to Medicare patients, you must issue a valid ABN before the service. Without it, you can't collect from the patient after a claim denial. Make sure your front desk and clinical staff understand when an ABN is required. |
| 3 | Train your billing team on the non-coverage position. Thermography billing for Medicare patients ends at claim denial. There's no appeals path that will reverse a denial based on CMS's non-coverage determination. Your team should know not to spend time appealing these. |
| 4 | Review any bundled or hybrid service offerings. Some practices offer thermography alongside covered services. If you're billing a covered service and a non-covered service in the same encounter, make sure you're not inadvertently contaminating a clean claim. Document the distinction clearly. |
| 5 | Update patient-facing communications. If your practice markets thermography as a service, your patient intake materials should clearly state that Medicare does not cover thermography. Set expectations before the appointment, not after. |
| 6 | Check for any local coverage determination (LCD) guidance from your Medicare Administrative Contractor (MAC). CMS sets national non-coverage, but your MAC may have issued additional local guidance. Search your MAC's LCD database to confirm there are no local variations that affect your billing guidelines. |
| 7 | If your practice has significant thermography volume or questions about specific coding scenarios, talk to your compliance officer before May 15, 2026. The boundary between a covered imaging service and a non-covered thermography application can get blurry in documentation. Don't guess. |
| 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 Thermography Under This Policy
The available policy data does not list specific CPT, HCPCS, or ICD-10 codes for this coverage policy. This is worth noting because it means CMS is applying non-coverage broadly — not tying it to a narrow set of codes.
What This Means for Thermography Billing
Because no specific codes are enumerated in the available data, your billing team should treat any thermography service billed to Medicare as non-covered, regardless of how it's coded. The clinical description of the service — not the code — drives the coverage determination here.
If your billing team is uncertain whether a specific code falls under this non-coverage policy, that's exactly the scenario where you should loop in your compliance officer or a billing consultant before the claim goes out. A wrong assumption here costs you twice: once on the claim denial, and once if the patient hasn't signed an ABN.
A Note on Code Research
If you need to identify specific CPT codes associated with thermography for your own internal mapping, the AMA CPT code set includes codes for thermography services. Search your encoder for "thermography" to pull those codes and cross-reference against this policy. But understand that the CMS non-coverage position covers the service, not just the code — recoding thermography as something else doesn't create coverage.
