Q92.0
Q92.0 — Whole chromosome trisomy, nonmosaicism (meiotic nondisjunction)
Billable / specific codeICD-10-CMPOA exempt
Q92.0 is a billable, specific ICD-10-CM code for whole chromosome trisomy, nonmosaicism (meiotic nondisjunction). It is valid for submission on a claim.
Risk adjustment
Q92.0 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 Q92.0 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 Q92.0.
- Trisomy›whole chromosome›meiotic nondisjunction
- Trisomy›chromosome specified NEC›whole›meiotic nondisjunction
