Bathroom and Toilet Equipment and Supplies — CPB 0429 | AETNA Coverage Update

Aetna modified CPB 0429, its bathroom and toilet equipment coverage policy, effective January 11, 2026. Here's what changes for billing teams.

Aetna, a CVS Health company, updated Clinical Policy Bulletin 0429 covering durable medical equipment (DME) for bathroom and toilet equipment and supplies. This update covers a large set of HCPCS codes — from E0163 and E0165 for commode chairs to E0240 for bath/shower chairs and E1301 for walk-in whirlpool tubs — and adds detailed criteria for rehab shower chairs and bathing systems. If your team bills DME for home health, rehabilitation, or complex neurological patients, this coverage policy affects you now.

Aetna Bathroom and Toilet Equipment Coverage Criteria and Medical Necessity Requirements 2026

CPB 0429 Aetna's updated policy draws hard lines around what qualifies as medically necessary. These aren't soft suggestions — missing one criterion means a claim denial.

Commode Chairs (E0163, E0165, E0168)

A standard commode chair — billed as E0163 (fixed arms) or E0165 (detachable arms) — requires the member to be physically incapable of using a regular toilet. That alone isn't enough. One of three additional conditions must also be met:

#	Covered Indication Copy
1	The member is confined to a single room, or
2	The member is confined to one level of the home and no toilet exists on that level, or
3	The member is confined to the home and no toilet facilities exist in the home at all

The detachable arms upgrade (E0165) adds one more layer. You need to show that the detachable arms are required for transfers or that the member's body configuration requires extra width. Don't bill E0165 as a default — document the transfer need or body configuration explicitly.

Commode Chair with Seat Lift (E0170, E0171)

E0170 (electric) and E0171 (non-electric) for commode chairs with integrated seat lift mechanisms require the member to meet both the commode chair criteria above and the separate medical necessity criteria in CPB 0459 for seat lifts. Here's the practical issue: a commode with seat lift is intended for someone who can walk after standing. If the member can ambulate, they'll rarely meet the full medical necessity standard for a commode. Your billing team needs to document ambulation status carefully here, or you're setting up a denial.

Bathing Systems / Rehab Shower Chair / Commode

This is where the policy gets complex — and where your prior authorization risk is highest. For members 12 months or older, a bathing system or rehab shower chair/commode is medically necessary only when all six of these criteria are met:

Six criteria. All six. Missing any one of them gives Aetna grounds to deny the claim. The ATP home assessment and the documented trial of the device are the two most commonly missed on claims we see. If your referral sources aren't capturing those, your reimbursement will stall.

Aetna Bathroom and Toilet Equipment Exclusions and Non-Covered Indications

Aetna's coverage policy draws a clear line at general convenience and safety. Codes like E0244 (raised toilet seat), E0245 (tub stool or bench), E0240 (bath/shower chair), E0247 and E0248 (transfer benches) appear in the policy code set for both HMO-based and traditional plans. Plan-specific applicability for these codes differs — verify individual member plan type and confirm coverage before billing.

Whirlpool equipment — E1300 (portable overtub), E1301 (walk-in portable), and E1310 (nonportable built-in) — is listed in the policy code set but is generally excluded. Verify plan-specific exclusions before billing these.

Sitz baths (E0160, E0161, E0162) and bed pans (E0275, E0276) are in the code set but have narrow covered indications. Don't assume coverage because the code is listed.

CPT, HCPCS, and ICD-10 Codes for Bathroom and Toilet Equipment Under CPB 0429

Covered HCPCS Codes (When Selection Criteria Are Met)

Key ICD-10-CM Diagnosis Codes

These diagnoses support medical necessity for bathing systems, rehab shower chairs, and commode coverage under CPB 0429. This is not the complete list — Aetna's policy includes 213 ICD-10 codes total.

Map to the most specific code the documentation supports. A generic paraplegia code when the record supports a spinal cord injury-specific code is a documentation gap Aetna will use against you.
