- Billable — Valid for Submission
- Risk Adjusts — HCC 23
- Chronic Condition
C63.2 is a billable ICD-10-CM diagnosis code for malignant neoplasm of scrotum. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 715 through 716, 722 through 724. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Male reproductive system cancers - all other types.
For Medicare Advantage risk adjustment, C63.2 maps to CMS-HCC Category 23 (Prostate, Breast, and Other Cancers and Tumors) under the V28 model, adding a risk factor of about 0.186 for a community, non-dual, aged beneficiary in payment year 2027.

Notes
General instructions on how these codes are used.
- Functional activity
- All neoplasms are classified in this chapter, whether they are functionally active or not. An additional code from Chapter 4 may be used, to identify functional activity associated with any neoplasm.
- Morphology [Histology]
- Chapter 2 classifies neoplasms primarily by site (topography), with broad groupings for behavior, malignant, in situ, benign, etc. The Table of Neoplasms should be used to identify the correct topography code. In a few cases, such as for malignant melanoma and certain neuroendocrine tumors, the morphology (histologic type) is included in the category and codes.
- Primary malignant neoplasms overlapping site boundaries
- A primary malignant neoplasm that overlaps two or more contiguous (next to each other) sites should be classified to the subcategory/code .8 ('overlapping lesion'), unless the combination is specifically indexed elsewhere. For multiple neoplasms of the same site that are not contiguous, such as tumors in different quadrants of the same breast, codes for each site should be assigned.
- Malignant neoplasm of ectopic tissue
- Malignant neoplasms of ectopic tissue are to be coded to the site mentioned, e.g., ectopic pancreatic malignant neoplasms are coded to pancreas, unspecified (C25.9).

Is C63.2 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report malignant neoplasm of scrotum on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does C63.2 group to?
When malignant neoplasm of scrotum is the principal diagnosis on an inpatient stay, it groups to MS-DRG 716, 723, 724, 715, 722, with relative weights from 0.5709 to 2.2896 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of C63.2?
Under the General Equivalence Mappings, malignant neoplasm of scrotum converts to ICD-9-CM 187.7 (malign neopl scrotum). The mapping is a direct match.
What HCC is C63.2?
C63.2 (malignant neoplasm of scrotum) maps to CMS-HCC Category 23 (Prostate, Breast, and Other Cancers and Tumors), commonly written as HCC 23, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 12 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 22.
Does C63.2 risk-adjust for Medicare Advantage payment?
Yes. When documented and reported on a Medicare Advantage encounter, C63.2 adds a risk adjustment factor of about 0.186 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.186 to 0.237 depending on the payment segment). A more severe related category (HCC 17, HCC 18, HCC 19, HCC 20, HCC 21, and HCC 22) supersedes it when both are reported. See the full factor table on the HCC 23 category page.
