Q83.0 — Congenital absence of breast with absent nipple
Q83.0 is a billable, specific ICD-10-CM code for congenital absence of breast with absent nipple. It is valid for submission on a claim.
Other codes that can never be billed with Q83.0
These codes carry an Excludes1 note pointing at Q83.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q83.0 alone.
- N64.82Hypoplasia of breast
Risk adjustment
Q83.0 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 Q83.0 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 Q83.0.
- Amastia›with absent nipple
- Agenesis›breast›with absent nipple
