Code
O7
Description
Initial prenatal visit already billed - paid as subsequent prenatal visit

Explanation

Updated October 26, 2026

O7 means the initial prenatal visit was already claimed, so this visit was paid as a subsequent prenatal visit.

What it means

O7 means the initial prenatal visit was already claimed, so this visit was paid at the subsequent prenatal visit fee.

A prenatal general assessment (P003) starts antenatal care. Later routine visits are minor prenatal assessments (P004) (Schedule K2 and K4).

Common causes

  • A second P003 billed for the same pregnancy

How to fix it

  1. Check whether a P003 was already paid for this pregnancy.
  2. If the reduction is correct, there is nothing to fix.
  3. If you believe the decision is wrong, send a Remittance Advice Inquiry (RAI) through eSubmit, or on form 0918-84, within 7 months of the RA date, with supporting details.

Don't resubmit if

  • P003 was already paid for this pregnancy.
  • The line is already on your RA. Question it with an RAI, not a new claim.
