What This Code Means

A rare skin lymphoma caused by abnormal T-cells with CD30 markers that has not achieved remission.

Coding Tips

• •Verify CD30-positive status is confirmed in pathology report
• •Ensure active disease status is documented and remission has not been achieved

Clinical Significance

Primary cutaneous CD30-positive T-cell proliferations represent a spectrum of skin lymphomas including lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma. These disorders are characterized by CD30 antigen expression on the malignant T-cells and generally have a more favorable prognosis than systemic CD30-positive lymphomas. Non-remission status indicates ongoing active skin disease that has not responded fully to therapy.

Documentation Requirements

• ✓Documentation must include skin biopsy with immunohistochemistry confirming CD30 positivity on T-cell infiltrates.
• ✓The specific entity within the CD30-positive spectrum should be documented if identified.
• ✓Extent of skin involvement, treatment modality (radiation, methotrexate, brentuximab), response assessment, and active disease status must be recorded.
