A major maternity coding change is due January 1, 2027—and it is much more than a routine annual update. The American Medical Association (AMA) is deleting the traditional global obstetric CPT structure and moving to separate reporting for four phases of care: antepartum, labor management, delivery, and postpartum. In total, 35 codes are affected (12 new, 17 deleted, 6 revised) and while the added detail should improve visibility into team-based maternity care, it also creates new opportunities for improper billing.
What to Look For
Pregnancies spanning both calendar years will require special attention. Antepartum services performed in 2026 may still be reported with CPT codes 59425 or 59426. However, in 2027 all antepartum encounters will be reported using office, hospital, telemedicine, or other appropriate E/M codes. Code selection must be based on the medical decision-making or time associated with each individual encounter—not on the overall risk level of the pregnancy.
Four new codes will distinguish initial-day from subsequent-day labor management and straightforward from complex care: 59080 and 59081 for Initial-day labor management and 59082 and 59083 for Subsequent-day labor management. Only one labor management code should generally be reported per calendar day.
Vaginal delivery will be reported with either 59431, or 59432 if the patient had a previous cesarean delivery. Cesarean delivery will be reported with 59502 for a primary cesarean and 59503 for a repeat cesarean. Remember though – only one cesarean delivery code is reported regardless of the number of fetuses delivered while vaginal delivery codes may be reported once for each fetus delivered.
HCFS Has You Covered
With the global CPT structure disappearing, prioritizing reviews will need to follow the patient across the full pregnancy rather than evaluating each claim line in isolation, thus requiring a layered approach. The HCFSPlatform™ supports this work using both AI and targeted alerts helping payers identify unusual billing trends, prioritize outlier activity, and focus investigative resources on areas with the greatest potential impact.
