Prenatal Care Provided by Primary Care Physicians — CPB 0047 | AETNA Coverage Update

Aetna modified CPB 0047 governing prenatal care by primary care physicians, effective September 26, 2025. Here's what billing teams need to do.

Aetna, a CVS Health company, updated CPB 0047 to clarify the billing guidelines and program enrollment requirements for family physicians providing prenatal care to Aetna members. The policy directly affects how you bill CPT codes 59425 and 59426 — the antepartum-only visit codes — and sets strict operational rules your practice must follow to get paid. If your family medicine or primary care practice provides any prenatal services to Aetna members, this coverage policy applies to you.

Aetna Prenatal Care Coverage Criteria and Medical Necessity Requirements 2025

The Aetna prenatal care coverage policy under CPB 0047 is narrower than most family physicians assume. Aetna members can choose to stay with their primary care physician (PCP) for prenatal care — but that doesn't mean the PCP can bill freely without meeting specific conditions first.

To establish medical necessity and get reimbursement, your practice must formally identify itself to Aetna as a prenatal care provider and agree to follow Aetna's policies for this care. This isn't optional. If you haven't completed that step, your claims for CPT 59425 and 59426 are at risk of claim denial regardless of the care you delivered.

The policy also requires that the member be offered a real choice between staying with the primary care practice and seeing a participating obstetrician. You need to document that the member made an informed decision to remain in your practice. That documentation supports medical necessity if a claim gets questioned later.

Prior authorization requirements for genetic testing are handled through the Aetna Beginning Right Maternity Program — not through the standard prior auth process. All genetic testing must be coordinated through that program. If you order genetic testing and route it outside of Beginning Right, expect a denial.

The co-management requirement is the other critical piece. Even when a member stays with the PCP for prenatal visits, she must have a participating obstetrician named as a co-manager of her care. The member's complete prenatal record must be available at the handoff visit. And that handoff to the OB must happen no later than the 28th week.

Aetna Prenatal Care Billing Guidelines and Action Items 2025

Here's what your billing team and practice administrator need to do before billing prenatal services under CPB 0047.

If you're not sure how these requirements interact with your existing prenatal billing workflow, loop in your compliance officer before the September 26, 2025 effective date.

CPT, HCPCS, and ICD-10 Codes for Prenatal Care Under CPB 0047

Covered CPT Codes (When Selection Criteria Are Met)

Note: Coverage for these codes requires that the practice is registered with Aetna, the member has chosen PCP-based prenatal care, and a participating OB is named as co-manager. Codes 59025 and 76801–76818 are covered under this policy but must be performed by — or referred to — the selected OB, not the PCP.

Key ICD-10-CM Diagnosis Codes

The policy covers a broad range of pregnancy supervision diagnoses. The O09 code family covers supervision of both normal and high-risk pregnancies. Use the most specific code available based on the member's pregnancy status and risk factors.

The full policy lists 188 ICD-10-CM diagnosis codes spanning the O09 pregnancy supervision code family. The policy data provided includes the first 55 codes. Review the full CPB 0047 policy document at app.payerpolicy.org/p/aetna/0047 for the complete ICD-10 list before updating your charge capture.

The Real Billing Risk in CPB 0047

Here's the honest take on this policy: it's operationally demanding for a primary care practice. Aetna prenatal care billing under CPB 0047 has eight distinct procedural requirements — registration, member choice documentation, OB co-management, Beginning Right enrollment, consent forms, referral timing, record transfer, and program-specific routing for genetic testing. Miss any one of them and you've created a claim denial vector or a compliance exposure.

The fee schedule reimbursement for CPT 59425 and 59426 only makes sense if your billing team executes cleanly against all eight requirements. Otherwise you're absorbing administrative cost and claim risk for a relatively low-dollar service line.

If you have a meaningful volume of Aetna prenatal patients in your family medicine practice, this is worth a formal workflow review — not just a quick update to the charge capture.
