C60.8
BillableMalignant neoplasm of overlapping sites of penis
Last updated: FY2026 ICD-10-CM (Oct 1, 2025 – Sep 30, 2026) | CMS-HCC V28 (100% phase-in, PY2026)
Is C60.8 an HCC code?
Yes. C60.8 maps to Melanoma and Other Skin Cancers under the CMS-HCC V28 risk adjustment model (and Breast, Prostate, and Other Cancers and Tumors under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for C60.8
For C60.8 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically — it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed C60.8 during that encounter — not just copy-forwarded from a problem list.
What This Code Means
C60.8 is the ICD-10-CM diagnosis code for malignant neoplasm of overlapping sites of penis. Cancer that involves multiple overlapping areas of the penis or cannot be assigned to a single specific site. This code is used when the tumor spans across different penile regions. C60.8 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering malignant neoplasms of male genital organs (c60-c63).
Under the CMS-HCC V28 risk adjustment model, C60.8 maps to Melanoma and Other Skin Cancers (HCC 23) with a community, non-dual, aged base RAF weight of 0.251. Under the older CMS-HCC V24 model, C60.8 maps to Breast, Prostate, and Other Cancers and Tumors (HCC 12) with a community, non-dual, aged base RAF weight of 0.150. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Use this code only when the tumor clearly involves more than one distinct anatomical site of the penis. Because C60.8 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for C60.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the tumor clearly involves more than one distinct anatomical site of the penis
- •Document all involved sites in the medical record to support the overlapping sites designation
Clinical Significance
This code is used when a penile cancer involves two or more contiguous anatomical subsites (e.g., glans extending into shaft, or prepuce and glans) and the point of origin cannot be determined. It indicates a larger tumor burden spanning multiple penile structures, which typically implies more advanced disease requiring aggressive treatment.
Documentation Requirements
- ✓Documentation identifying which specific penile subsites are involved (e.g., glans and shaft)
- ✓Pathology confirming that the tumor spans contiguous sites
- ✓Statement that the primary point of origin cannot be determined
- ✓TNM staging with tumor size and depth
- ✓Lymph node involvement assessment
