Global maternity packages like 59400 and 59510, split-billed antepartum visits after transfer of care, and OB ultrasound coding each carry their own payer rules, and one wrong modifier can bundle away thousands. MedTaskly's AAPC-certified OB-GYN billing team captures every antepartum, delivery, and gyn charge so you get paid faster with fewer denials.
Book Free RCM AuditOB-GYN medical billing is harder because most maternity care is paid through a single global package, such as CPT 59400 for vaginal delivery or 59510 for cesarean, covering antepartum visits, delivery, and postpartum care. When a patient transfers care mid-pregnancy or changes insurance, practices must split-bill antepartum visits with codes like 59425 or 59426, and getting that wrong means denied or underpaid claims.
Bundled deliveries, split-billed visits, and ultrasound edits quietly erode collections.
OB-GYN revenue runs through the global maternity package. CPT 59400 covers antepartum care, vaginal delivery, and postpartum care as one payment, while 59510 does the same for cesarean deliveries. That structure creates traps: bill an office visit that belongs inside the package and it denies, but miss a legitimate split-bill when a patient transfers care, and you leave money behind. Codes 59425 (4-6 antepartum visits) and 59426 (7 or more) exist for exactly those transfer-of-care scenarios, yet many practices never use them correctly.
Ultrasounds add another layer, since payers apply different rules to 76801, 76805, and 76817 and often deny repeat scans without documented medical necessity. Gyn procedures and well-woman exams bring their own modifier and frequency edits. MedTaskly's AAPC-certified coders handle OB-GYN billing for practices nationwide, part of the 1,500+ providers we serve, and our 98% clean-claim rate means claims go out right the first time, so you get paid faster with fewer denials.
