Overview
SOMB code 03.03B is paid for a prenatal follow-up visit in the office. It is strictly prenatal: it cannot be used for general office visits. Pair the initial prenatal visit with 03.04B, and use 03.03B for subsequent routine prenatal follow-ups.
Billing Requirements
- In-office prenatal follow-up with the patient
- Gestational-age-appropriate assessment performed and documented
Common Audit Traps
⚠️ Alberta Health auditors specifically look for these mistakes when reviewing 03.03B claims:
- Billing 03.03B for non-prenatal office visits
- Using 03.03B for the initial prenatal visit (use 03.04B instead)
Clinical Example
Routine prenatal follow-up at 28 weeks — BP, fundal height, fetal heart rate, relevant history. Bill 03.03B.
Documentation Tips (Audit-Proof)
- Record gestational age and routine prenatal parameters
- Document any concerns raised and follow-up plan
