OB/GYN Medical Billing Services in California
AMS Solutions provides specialized ob/gyn medical billing for practices across California. Whether you’re in Los Angeles, San Francisco, San Diego, Sacramento, or anywhere statewide, our AAPC-certified billers handle the full ob/gyn code set (the maternity global package (59400, 59510, 59610, 59618), the full ultrasound set (76801-76817), and GYN procedures) and the complex California payer landscape including Medi-Cal Managed Care that California practices encounter.
California-specific payer landscape
California OB/GYN billing crosses Medi-Cal Managed Care (Anthem Blue Cross Partnership, Blue Shield Promise, Health Net, L.A. Care, Inland Empire Health Plan), commercial Blue Shield and Anthem, Kaiser (when out-of-network), UnitedHealthcare, Cigna, and Aetna. Noridian is the MAC for CA Medicare Part B with its own LCDs.
Where California ob/gyn revenue leaks
- Medi-Cal Managed Care patient transfers mid-pregnancy — antepartum-only splits (59425/59426)
- Multi-gestation ultrasound coding (76802, 76810) on twins/IVF pregnancies
- Same-day GYN procedure + E/M bundling without Modifier 25
- Medi-Cal Family PACT enrollment and billing for family planning services
- 21-day Medi-Cal claim submission window — late = denied
