Q52.1 — Doubling of vagina
Q52.1 is a non-billable header ICD-10-CM code for doubling of vagina. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- doubling of vagina with doubling of uterus and cervix (Q51.1-)
Risk adjustment
Q52.1 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 Q52.1 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 Q52.1.
