Aetna modified CPB 0423 for alopecia areata, effective September 26, 2025. Here's what billing teams need to know before claims go out the door.
Aetna, a CVS Health company, updated its alopecia areata coverage policy under CPB 0423 Aetna system. The revision clarifies medical necessity criteria for mild versus extensive disease and adds topical immunotherapy — diphenylcyclopropenone (DPCP/DCP) and squaric acid dibutyl ester (SADBE) — as a covered option for extensive alopecia areata after conventional treatments fail. Primary affected codes include CPT 11900, 11901, and 96912, plus a broad set of HCPCS J-codes for corticosteroid injections. If your practice sees dermatology patients on Aetna plans, review your charge capture and authorization workflows before September 26, 2025.

Aetna Alopecia Areata Coverage Criteria and Medical Necessity Requirements 2025
CPB 0423 splits alopecia areata coverage into two clinical tracks. The dividing line is 50% scalp hair loss. Get that documentation right, or you'll face claim denial before you ever get to treatment arguments.
Mild alopecia areata — less than 50% scalp hair loss. Aetna considers two treatments medically necessary in this category: topical anthralin and glucocorticoids administered topically or intralesionally. Intralesional injections bill under CPT 11900 (up to seven lesions) or CPT 11901 (more than seven lesions), with HCPCS codes J3301 (triamcinolone acetonide, 10 mg), J1010 (methylprednisolone acetate, 1 mg), J1100 (dexamethasone sodium phosphate, 1 mg), or J2919 (methylprednisolone sodium succinate, 5 mg) for the drug itself. Medical necessity documentation here is straightforward: confirm diagnosis, measure affected surface area, and select an approved agent.
Extensive alopecia areata — greater than 50% scalp hair loss. The covered treatment list expands here. Aetna covers topical anthralin, glucocorticoids (oral, topical, or intralesional), and PUVA photochemotherapy (CPT 96912). Oral corticosteroids billing through the HCPCS J-code set also falls under this track. If you're billing 96912 for PUVA, cross-reference Aetna's CPB 0205 (Phototherapy and Photochemotherapy), which governs that specific service — the coverage policy for alopecia does not stand alone here.
Topical immunotherapy for extensive disease — the new wrinkle. This is the change that will actually affect your workflows. Aetna now covers DPCP/DCP and SADBE for patients with greater than 50% scalp hair loss, but only after conventional therapies fail. The policy specifically names a short course of systemic glucocorticoids, oral baricitinib, or oral ritlecitinib as the required prior treatments. Neither oral baricitinib nor oral ritlecitinib has a dedicated HCPCS code in this policy — the code tables note "no specific code" for both. That matters for alopecia areata billing because you'll need to document the failure of those agents through chart notes and prior authorization, not through a clean HCPCS claim line.
The real issue here is the step-therapy requirement. Aetna is saying: try the JAK inhibitors or systemic steroids first. If those fail, then topical immunotherapy becomes a covered option. Your prior authorization request for DPCP or SADBE needs to show that trial-and-failure clearly. If it doesn't, expect denial.
Aetna Alopecia Areata Exclusions and Non-Covered Indications
The code tables in CPB 0423 are blunt about what Aetna won't pay for. A large group of CPT and HCPCS codes appear under labels tied to "Interleukin-12, interleukin-17, interleukin-18 gene polymorphisms" and other investigational markers — these represent treatments Aetna considers experimental or not medically necessary for alopecia areata.
Specifically excluded services include:

Aetna Alopecia Areata Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Document disease severity before the September 26, 2025 effective date. The mild/extensive split at 50% scalp hair loss drives everything in this policy. Your chart notes need to quantify affected surface area — not just a general "alopecia areata" diagnosis. Without severity documentation, Aetna has grounds to deny any claim under this coverage policy. |
| 2 | Audit current charge capture for excluded services. Pull claims from the last 12 months where you billed CPT 0232T, 0481T, 0552T, or HCPCS P9020 for alopecia patients on Aetna plans. If those claims paid, you may have overpayments sitting in your accounts. Talk to your compliance officer before the effective date — this is the kind of thing that surfaces in audits. |
| 3 | Build a step-therapy documentation template for topical immunotherapy. If you plan to bill for DPCP or SADBE after September 26, 2025, your prior authorization request needs to show failure of at least one conventional therapy. The policy names systemic glucocorticoids, oral baricitinib, and oral ritlecitinib. Create a standard template that captures drug name, dose, duration, and reason for discontinuation. Vague notes like "patient did not tolerate steroids" won't hold up. |
| 4 | Update your prior authorization workflow for PUVA referrals. CPT 96912 is covered for extensive alopecia areata, but Aetna's coverage policy ties it to CPB 0205 for the full phototherapy criteria. If your practice refers patients out for PUVA, make sure the receiving provider has the right prior auth in place under both CPBs. A gap here is a common source of claim denial in phototherapy billing. |
| 5 | Confirm pharmacy versus medical benefit routing for oral agents. Oral baricitinib and oral ritlecitinib have no specific HCPCS code in this policy. They're listed as prior conventional treatments — not separately billable services under the medical benefit. If your team has been trying to bill these through J-codes or infusion codes, stop. Route them through the pharmacy benefit and document them as part of the treatment history for step-therapy purposes. |
| 6 | Remove excluded services from your alopecia areata order sets. If your EHR order sets for alopecia include PRP (CPT 0232T), low-level laser (CPT 0552T), or micronutrient labs (CPT 82306, 82652, 83540, 83735, 84255, 84630), remove them or flag them as non-covered under Aetna plans. Ordering these services and billing them sets up avoidable denials and patient balance disputes. |
