Supervision of high risk pregnancy, unspecified, first trimester

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Medical supervision of a high-risk pregnancy with an unspecified risk factor during the first trimester (weeks 1-13).

Coding Tips

  • Use the fifth character '1' to indicate first trimester; this code is appropriate when high-risk status is documented but the specific condition is not clearly identified
  • Consider querying the provider to identify the actual high-risk condition for more specific coding
