C52 — Malignant neoplasm of vagina
C52 is a billable, specific ICD-10-CM code for malignant neoplasm of vagina. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- carcinoma in situ of vagina (D07.2)
Other codes that can never be billed with C52
These codes carry an Excludes1 note pointing at C52. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C52 alone.
- C44Other and unspecified malignant neoplasm of skin
Risk adjustment
C52 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 22 Bladder, Colorectal, and Other Cancers0.363 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
