HCC Category Mapping

What This Code Means

A type of skin cancer involving abnormal T-cells that are CD30-positive and have responded well to treatment with no signs of disease remaining.

Coding Tips

• •This code specifically indicates remission status; use C86.60 if remission status is unknown or not achieved
• •Document the specific type of cutaneous lymphoma and current treatment response in the medical record

Clinical Significance

Primary cutaneous CD30-positive T-cell proliferations in remission indicates the skin lymphoma has responded to treatment with resolution of active lesions. The generally favorable prognosis of primary cutaneous CD30-positive disease means remission is achievable in many patients. However, some entities in this spectrum (particularly lymphomatoid papulosis) have a characteristically relapsing-remitting course requiring ongoing dermatologic surveillance.

Documentation Requirements

• ✓Provider must explicitly document remission with evidence of resolved skin lesions on clinical examination.
• ✓The original diagnosis confirming CD30-positive T-cell proliferation must be in the record.
• ✓Dermatologic surveillance plan and any concern for transformation to a more aggressive lymphoma should be documented.
