0.000What This Code Means
Mantle cell lymphoma that is currently in remission, meaning cancer cells are no longer detectable.
Coding Tips
- •Only use when documentation explicitly states remission status
- •Verify remission is complete; do not use if patient has relapsed or partial response only
Clinical Significance
Mantle cell lymphoma in remission indicates treatment response with no detectable disease. Given mantle cell lymphoma's tendency to relapse, ongoing surveillance is critical. Patients may be on maintenance rituximab or other agents. This code captures continued risk adjustment value during surveillance while accurately reflecting the patient's current disease status.
Documentation Requirements
- ✓Explicit provider documentation of remission (complete or partial specified)
- ✓Date of remission achievement
- ✓Surveillance imaging schedule and results (PET/CT or CT)
- ✓Current maintenance therapy if applicable (rituximab, lenalidomide)
- ✓Monitoring laboratory studies (CBC, LDH, beta-2 microglobulin)
Commonly Confused Codes
C83.10 — Active mantle cell lymphoma, unspecified; do not use when remission is documentedZ85.79 — Personal history of lymphoid malignancy; use only when no longer under active surveillance, not during remission monitoringC83.11-C83.19 — Active site-specific codes; replace with C83.1A once remission is documented
