Tracheostomy Supplies — CPB 0074 | AETNA Coverage Update

Aetna modified CPB 0074 covering tracheostomy supplies, effective September 26, 2025. Here's what billing teams need to do.

Aetna, a CVS Health company, updated Clinical Policy Bulletin CPB 0074 governing tracheostomy supply coverage. The policy covers 25 HCPCS codes — from inner cannulas (A4623) and tracheostomy tubes (A7520–A7522) to heat and moisture exchange system components (A7504–A7509) — and explicitly excludes two codes: A7523 (shower protector) and A7527 (tube plug/stop). If your practice or DME supplier bills tracheostomy supplies to Aetna patients, this coverage policy update affects your charge capture and claim submission processes now.

Quick-Reference Table

Aetna Tracheostomy Supplies Coverage Criteria and Medical Necessity Requirements 2025

The Aetna tracheostomy supplies coverage policy covers 25 HCPCS codes when selection criteria are met. "When selection criteria are met" is the operative phrase. It means medical necessity documentation must support each item billed.

For tracheostomy supply billing, the relevant ICD-10 anchors are Z93.0 (tracheostomy status), Z43.0 (encounter for attention to tracheostomy), and the J95.x family (J95.0 through J95.9) covering tracheostomy complications. Your claims need one of these codes on the face of the claim. Missing that linkage is one of the fastest routes to a claim denial.

Medical necessity means the patient actively requires the specific supply billed. Billing a tracheostoma valve (A7501) or replacement diaphragm (A7502) requires documentation that the patient uses a tracheostoma valve system. Billing heat and moisture exchange components — A7504 through A7509 — requires documentation of HME system use. Aetna does not reimburse for supplies sitting in a closet.

Prior authorization requirements for tracheostomy supplies under CPB 0074 are not explicitly detailed in the current bulletin text. That does not mean prior auth is never required. Check the patient's specific plan benefits before billing, particularly for higher-cost items like tracheostoma valves (A7501) and stainless steel tracheostomy tubes (A7522). Some Aetna plan designs layer additional prior authorization requirements on top of the base CPB.

The policy covers both new tracheostomy care kits (A4625) and established tracheostomy care kits (A4629). That distinction matters for billing. A4625 is appropriate for new tracheostomy patients. A4629 is for ongoing, established care. Billing A4625 repeatedly for a long-term tracheostomy patient will draw scrutiny.

Aetna Tracheostomy Supplies Exclusions and Non-Covered Indications

Two codes are explicitly not covered under CPB 0074 regardless of indication:

A7523 — Tracheostomy shower protector, each. Aetna does not cover this item. Full stop. If your charge capture includes A7523 as a routine add-on for tracheostomy patients, remove it. Billing this code to Aetna produces a denial.

A7527 — Tracheostomy/laryngectomy tube plug/stop, each. Also not covered. This is worth flagging for ENT and speech-language pathology billing teams who sometimes include plugs as part of speaking valve trials or decannulation protocols. Aetna will not reimburse A7527.

If you bill A7523 or A7527 today, update your charge capture before submitting any claims against this updated policy. These are not "covered with restrictions" — they are listed as non-covered for indications listed in the CPB. The financial exposure here is straightforward: every claim with these codes goes to denial.
