Z98.870Personal history of in utero procedure during pregnancy

Billable / specific codeICD-10-CMPOA exempt

Z98.870 is a billable, specific ICD-10-CM code for personal history of in utero procedure during pregnancy. It is valid for submission on a claim.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • complications from in utero procedure for current pregnancy (O35.7)
  • supervision of current pregnancy with history of in utero procedure during previous pregnancy (O09.82-)

Risk adjustment

Z98.870 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How Z98.870 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Z98.870.
