Home Health Aides — CPB 0218 | AETNA Coverage Update

TL;DR: Aetna modified CPB 0218 covering home health aide services, effective January 5, 2026. Here's what billing teams need to know before submitting claims under CPT 99509.

Aetna, a CVS Health company, updated its home health aide coverage policy under CPB 0218 Aetna system on January 5, 2026. The core change codifies the medical necessity criteria that must be met before Aetna pays for home health aide services billed under CPT 99509. If your practice or agency submits home health aide claims to Aetna, this policy sets the two-part test your documentation must clear—and it draws a sharp line between what qualifies and what gets denied.

Aetna Home Health Aide Coverage Criteria and Medical Necessity Requirements 2026

The Aetna home health aide coverage policy under CPB 0218 uses a hard two-part test. Both criteria must be satisfied for Aetna to consider services medically necessary. Neither alone is enough.

Criterion 1: The home health aide must work alongside intermittent skilled home health care. That skilled care must come from a licensed practical nurse, registered nurse, occupational therapist, physical therapist, or speech therapist. No concurrent skilled care means no coverage for the aide.

Criterion 2: The aide's services must directly support the skilled care being delivered. Aetna lists six permitted service types under this criterion:

This is the piece that trips up the most claims. The aide isn't just there to help the member get dressed. Every service must tie back to the skilled plan of care. If you can't show that connection in the documentation, Aetna will treat the aide's services as custodial—and deny reimbursement.

CPT 99509 is the primary code for home visit assistance with ADLs and personal care. It's the only code listed under "covered if selection criteria are met." Your prior authorization requests and your claims both need to reflect the skilled care relationship explicitly. Don't assume the reviewer will infer it.

There's also a narrow carve-out for Aetna's Beginning Right maternity program. Members on prescribed bed rest may qualify for home health services to cover routine household chores. This is the one situation where the policy loosens slightly—but it applies only within that specific program, not to general home health aide cases.

Aetna Home Health Aide Exclusions and Non-Covered Indications

Aetna draws three hard exclusions in CPB 0218. These are not gray areas. Claims for these services will face claim denial regardless of how the documentation is structured:

Babysitting services. Childcare in any form is not covered. If an aide is watching children while the member is receiving care elsewhere in the home, that time isn't billable.

House cleaning. General housekeeping is excluded. The policy creates one narrow exception: maintaining the member's immediate area. That means the space the member occupies during care—not whole-home cleaning.

Transportation. Driving members to appointments or errands is not a covered service under this policy.

These exclusions exist because home health aide services are defined by Aetna as non-skilled care that supports the skilled plan of care. Babysitting, cleaning, and transportation don't support a clinical plan. They're convenience services, and Aetna treats them that way.

The real issue here is documentation creep. An aide who does a little of everything—some ADL support, some light housekeeping, some childcare—exposes your agency to a recoupment demand if Aetna audits. Keep visit notes focused on what directly supports the skilled care. Everything else should stay out of the record.

Covered CPT Codes (When Selection Criteria Are Met)

Code	Type	Description Copy
99509	CPT	Home visit for assistance with activities of daily living and personal care

Other CPT Codes Related to CPB 0218

These codes appear in the policy as contextually related—either for the concurrent skilled services that must be present, or for the broader home health episode. They're not independently covered under CPB 0218's aide criteria, but they may appear on the same claim or in the same authorization request.

The policy data includes 24 additional CPT codes in the 99500 series and 399 HCPCS codes. See the full CPB 0218 policy on the Aetna provider portal for the complete code list.

Note on ICD-10 codes: The policy data provided for CPB 0218 does not list specific ICD-10-CM diagnosis codes. Coverage determinations under this policy are driven by medical necessity criteria and service type—not by diagnosis code alone. Check member-level plan documents and confirm with Aetna provider relations if your claims require diagnosis-level specificity for prior authorization.
