The Service Line

Medicare chose one obstetric billing system, not two, and the choice landed yesterday. The Centers for Medicare & Medicaid Services (CMS) released the final 2027 Medicare Physician Fee Schedule on November 4 without the 15 Medicare-only HCPCS G-codes it proposed in July to preserve the global delivery package, according to the American College of Obstetricians and Gynecologists (ACOG) as reported by Medical Economics. On January 1, Medicare adopts the American Medical Association’s unbundled maternity codes: separate codes for prenatal care, labor management, delivery and postpartum care, with each prenatal and postpartum visit billed as its own evaluation and management visit. ACOG had warned the G-codes would split patients into two billing tracks depending on who pays, and the final rule removes that risk for Medicare. We covered the fight on October 22, when the final rule was still pending. So what: the contract fallback clauses we flagged last time can now be collapsed to the new-code scenario for Medicare, though Medicaid managed-care plans and commercial payers still decide their own timelines. Confidence: High on the G-code removal (ACOG statement and trade report agree); Med on details, because I did not retrieve the CMS final rule text and ACOG’s page was not readable this run.

Reimbursement

Pregnancies that start in 2026 and end in 2027 get a transition path, but only for health plans. ACOG reports that the Department of Health and Human Services will allow health plans to use the 2026 CPT maternity care codes in 2027 for pregnancies whose services begin in 2026 and end in 2027, per Medical Economics. The article does not say whether the same relief applies to Medicare. Who it hits: every practice with patients mid-pregnancy on January 1, which is every practice delivering in the first nine months of 2027. So what: ask each payer in writing which code set governs a delivery in February for a patient whose first prenatal visit was in October, and decide now how your billing system splits the global fee for those patients.

Enforcement

Nothing obstetrics-specific surfaced from the Justice Department, HHS Office of Inspector General (OIG) or state Medicaid Fraud Control Units in this window. The standing reference remains the July 30 Justice Department settlement of $36.4 million over genetic-testing kickbacks and unnecessary testing, which is not described as prenatal. OIG’s June audit of Medicaid maternal health network lists has a CMS implementation update due December 10.

Who’s Buying

A children’s hospital system is buying an obstetrics practice just as the billing model changes. Akron Children’s announced in July that it will acquire the Stark Women’s Center in Canton, Ohio, which has six physicians and two nurse practitioners, with completion expected by February 2027. Terms were not disclosed. So what: the closing falls after the January 1 code change, which means the employment contracts and wRVU pay plans for those physicians will be written against per-visit billing from day one. For context, LevinPro HC counted eight OB/GYN physician group acquisitions in 2026 as of mid-June. Confidence: High on the announcement as stated by the hospital; Low on any price, which is undisclosed. Sources: Akron Children’s, LevinPro HC.

Clinical Policy

No clinical-policy shift in this vertical changed utilization or staffing economics this window. The live access thread is unchanged: the Center for Healthcare Quality and Payment Reform’s rural maternity tracker still counts 146 rural hospitals that have stopped delivering or announced they will since the end of 2020, as of July 2026, and local outlets continue to report unit closures such as MaineHealth’s Lincoln Hospital, effective December 18.

The Operator Metric

The number to track this week: about 4 fewer work relative value units (wRVUs) per vaginal delivery, against the 37 the global delivery code credits today. Consulting firm PYA’s modeling, cited by Medical Economics, assumes 8 prenatal and 2 postpartum visits for an uncomplicated vaginal delivery. The payment change is meant to be budget neutral overall, but PYA’s Carol Carden noted that does not mean neutral for each provider. The effect falls hardest on hospital-employed obstetrician-gynecologists paid partly on wRVUs, because midwives and advanced practice providers now bill their own visits and the physician loses credit for that work. Private practices paid on collections will see the shift in cash timing instead. Some employers plan to freeze OB pay at 2026 levels, with reconciliation at 3, 6 and 9 months. Confidence: Med; one consultancy’s model reported through trade press, and the dollar effect was not published. Source: Medical Economics.
