OB/GYN Medical Billing & Coding Alert

Question: What defines a post-term pregnancy in OBGYN coding, and how should it be accurately reported?

Answer: Pregnancies extending beyond 40 weeks are classified as either "post-term pregnancies" (40 to 42 weeks) or "prolonged pregnancies" (over 42 weeks).

Specifically, if the physician notes that the pregnancy is between 40 and 42 weeks (from 40 weeks and 1 day to 42 weeks exactly), you should use code O48.0. If the pregnancy goes beyond 42 completed weeks (from 42 weeks and 1 day onwards), you should report it with code O48.1.

For these situations, the applicable diagnosis codes are:

  • O48.0 (Post-term pregnancy)
  • O48.1 (Prolonged pregnancy)

Additionally, don’t forget to include a Z3A diagnosis code that specifies the gestational week at the time the pregnancy is reported as late.
