What practices need to know

Transition date and billing date are not interchangeable.

A transition date can determine how prenatal services beginning in 2026 are handled, while the billing date identifies when the payer says the new claim approach takes effect. Records without confirmed 2027 guidance remain clearly labeled and should not drive a billing change.

Scope and operational notes

Evidence scope: parent payer guidance; product applicability must be verified

Transition guidance: For EDD in 2027, preventive prenatal visits on/after 2026-09-01 may transition when three or fewer visits occur before 2027; four or more 2026 visits follow current antepartum billing.

Evidence standard

How this directory is maintained

Each record requires a matched payer or plan plus a direct policy source, the upstream page where that source was found, and a payer policy-index link. General CPT guidance is not treated as proof of a payer's implementation.

Confirmed guidance, proposals, and current-policy-only evidence are separate. Dates shown as “not published” remain unknown; they are not estimated from another payer. Before claim submission, verify the member's exact payer, plan, state, line of business, current source language, and date of service.

Research note: This resource is operational policy intelligence, not legal, medical, or coding advice.

Frequently asked questions

2027 OB/GYN payer billing questions

When do 2027 OB/GYN maternity billing changes begin?

There is no single payer-wide transition date. This directory separates each payer's published transition date from its billing effective date and labels proposed or current-policy-only evidence so it is not mistaken for a final 2027 requirement.

Does every payer require individual maternity-service billing in 2027?

No. The evidence differs by payer, plan, state, and line of business. Some payers published confirmed 2027 guidance, some sources are proposals, and other records only document current maternity policy without a matched 2027 implementation rule.

How should practices use this payer policy directory?

Search the exact payer and member product, review the direct policy and upstream policy page, confirm the transition and billing dates, and recheck the source before submitting claims. This is policy intelligence, not coding or legal advice.

Can I download policies for multiple payers?

Yes. Select payer rows and download an offline source packet containing the policy summary and direct, upstream, policy-index, and Substrate payer-page links. The source documents remain on each payer's website.
