TL;DR: The Centers for Medicare & Medicaid Services modified NCD 147 governing scalp hypothermia during chemotherapy, effective March 7, 2026. The core rule: scalp cooling supplies are covered as incidental supplies — but no separate charge is recognized.
If your oncology billing team has been submitting separate line items for scalp cooling equipment or supplies, this policy puts a hard stop on that. The CMS scalp hypothermia coverage policy does not list specific CPT or HCPCS codes, which creates its own set of billing problems. Here's what you need to know before claims start hitting the floor.

CMS Scalp Hypothermia Coverage Criteria and Medical Necessity Requirements 2026
NCD 147 is the National Coverage Determination governing Medicare coverage of scalp hypothermia during chemotherapy. The Centers for Medicare & Medicaid Services has confirmed that scalp cooling — whether done with ice-filled bags, cold bandages, or purpose-built devices — may be covered under Medicare. But the mechanism of coverage is everything here.
Coverage falls under two benefit categories. First, incident to a physician's professional service. Second, outpatient hospital services incident to a physician's service. That framing tells you exactly how to handle this in your charge capture.
The policy treats scalp hypothermia supplies as "supplies of the kind commonly furnished without a separate charge." That phrase is doing a lot of work. It means these supplies ride along with the underlying chemotherapy service — they do not stand alone as separately billable items. Medical necessity for the scalp cooling itself is implied by the chemotherapy administration, not independently established through prior authorization or separate diagnosis coding.
This coverage policy does not require prior authorization for scalp hypothermia supplies. They're subsumed into the chemo visit. But that also means you cannot drive separate reimbursement for them. If your team has been billing a cold cap device or ice pack supplies as an add-on, stop. CMS will not recognize a separate charge.
Whether scalp hypothermia is covered under Medicare depends entirely on how it's positioned on the claim. It cannot generate its own payment. It's an incidental supply attached to a covered chemotherapy encounter — full stop.
CMS Scalp Hypothermia Exclusions and Non-Covered Indications
The policy is clear on one exclusion: separate charges for scalp hypothermia supplies will not be recognized by Medicare. That applies regardless of what device is used — ice bags, chemical cold packs, or commercial scalp cooling systems.
There's no pathway in NCD 147 to bill scalp cooling as a standalone service or durable medical equipment item. The policy does not address home-use scenarios, which means if a patient uses a scalp cooling device outside of the clinical encounter, coverage is not established here. Talk to your compliance officer before attempting to bill any home-use scalp cooling under this NCD.
The policy also does not differentiate between manual cooling methods (ice packs) and technology-based systems (purpose-built chemical cooling devices). Both are treated identically — covered as incidental supplies, not separately billable.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Scalp hypothermia using ice-filled bags or bandages during chemotherapy | Covered (as incidental supply) | None specified in policy | No separate charge recognized; bundled with chemo encounter |
| Scalp hypothermia using specialty cooling devices during chemotherapy | Covered (as incidental supply) | None specified in policy | No separate charge recognized; bundled with chemo encounter |
| Separate billing for scalp cooling supplies or devices | Not Covered | None specified in policy | CMS explicitly states no separate charge will be recognized |
| Home-use scalp cooling outside the clinical encounter | Not Addressed | None specified in policy | No coverage established under NCD 147; consult your compliance officer |
CMS Scalp Hypothermia Billing Guidelines and Action Items 2026
The scalp hypothermia billing picture under NCD 147 is simple in principle and messy in practice. Here are the steps your billing team needs to take before and after the March 7, 2026 effective date.
| # | Action Item |
|---|---|
| 1 | Audit your outpatient oncology charge master now. Look for any line item — supply code, HCPCS code, or miscellaneous code — that has been used to bill scalp cooling supplies separately. If it's there, flag it for removal or suppression on Medicare claims. |
| 2 | Review claims submitted after March 7, 2026 for improper line items. If your team has already submitted claims with separate scalp cooling charges, pull those claims. A claim denial or post-payment audit is coming if CMS processes them and finds a separate line. Correct before they do. |
| 3 | Do not create a workaround using miscellaneous HCPCS codes. NCD 147 does not list specific codes, and that void tempts some billers to use unlisted or miscellaneous codes to capture the cost. CMS's position is that no separate charge is recognized — period. A miscellaneous code doesn't change that. |
| 4 | Confirm your charge capture workflow treats scalp cooling supplies as bundled. The supplies should be absorbed into your cost center for the chemotherapy infusion visit. They are not separately payable, so they should not appear as a separate revenue line on the claim. |
| 5 | Document the clinical encounter correctly. The chemotherapy administration must be properly coded and documented. Scalp hypothermia is incidental to that service. If the underlying chemo encounter isn't properly supported, you lose coverage for the entire visit, including the cooling supplies. |
| 6 | Train your oncology coders on the incident-to rules. The two benefit categories in this policy — incident to a physician's professional service and outpatient hospital services incident to a physician's service — have specific billing guidelines under Medicare. Make sure your team knows how these apply to infusion center workflows. |
| 7 | Check with your Medicare Administrative Contractor if you have edge-case scenarios. NCD 147 does not address every clinical situation. If your facility has questions about specific device types or unusual clinical settings, your MAC is the right call before the effective date of March 7, 2026. |
The real risk here isn't a complex medical necessity battle. It's operational — billing teams running on autopilot who haven't checked whether a supply charge is bundled or separate. A claim denial for an improper separate charge is avoidable. Audit now.

CPT, HCPCS, and ICD-10 Codes for Scalp Hypothermia Under NCD 147
This is where the policy creates a practical headache. NCD 147 does not list specific CPT codes, HCPCS codes, or ICD-10-CM diagnosis codes.
That is unusual for a National Coverage Determination. Most NCDs anchor their coverage rules to specific procedure codes. This one does not. The absence of codes in NCD 147 is itself important billing information — it means there is no approved billing vehicle for scalp hypothermia as a standalone service under Medicare.
No Covered Procedure Codes Listed
The policy does not provide covered CPT or HCPCS codes for scalp hypothermia. Scalp cooling supplies are bundled into the chemotherapy administration encounter. The procedure codes driving reimbursement are the chemotherapy administration codes — not scalp hypothermia codes.
No Excluded or Experimental Codes Listed
NCD 147 does not enumerate excluded codes either. The exclusion is structural: separate charges are not recognized. Any code submitted for a separate scalp cooling charge falls outside policy coverage, regardless of what code is used.
No ICD-10-CM Codes Listed
The policy does not specify diagnosis codes. Scalp hypothermia is incidental to chemotherapy — the underlying cancer diagnosis and chemotherapy administration codes drive the encounter. No separate diagnosis coding pathway exists for scalp cooling under this NCD.
What this means for your billing team: Do not fabricate a code pathway for scalp hypothermia billing under Medicare. The policy's silence on codes is deliberate. If you're billing for chemotherapy administration under Medicare and using scalp cooling, the cooling is already covered — invisibly, as a bundled supply. Trying to surface it as a separate billable item creates a claim denial exposure without any upside.
If your facility invested significantly in commercial scalp cooling systems and is looking for a reimbursement path beyond bundled supplies, that conversation requires your compliance officer, your CFO, and likely your MAC. NCD 147 as written does not provide one.
