0.000What This Code Means
Sézary disease that is currently in remission, meaning the cancer is controlled and symptoms are not active.
Coding Tips
- •Only assign this code when documentation explicitly states the disease is in remission or complete response
- •This code indicates the patient has had Sézary disease but it is currently controlled
Clinical Significance
Sezary disease in remission indicates this aggressive leukemic T-cell lymphoma has responded to treatment with resolution of circulating Sezary cells, skin involvement, and lymphadenopathy. Remission in Sezary disease is relatively uncommon given its aggressive nature, and patients require intensive surveillance due to high relapse rates. This code captures the ongoing complexity of managing a patient in remission from this high-mortality lymphoma.
Documentation Requirements
- ✓Explicit provider documentation of remission status
- ✓Resolution of circulating Sezary cells on peripheral blood analysis
- ✓Clear skin examination documenting resolution of erythroderma
- ✓Resolution of lymphadenopathy on imaging
- ✓Ongoing surveillance plan with blood work and skin monitoring
Commonly Confused Codes
C84.10-C84.19 — Active Sezary disease by site: Use only when disease is activeC84.0A — Mycosis fungoides, in remission: Distinct diagnosis; verify the correct cutaneous T-cell lymphoma subtypeZ85.79 — Personal history of lymphoid malignancies: Rarely appropriate for Sezary disease given its high relapse rate
