0.000What This Code Means
A type of B-cell cancer that is currently in remission, meaning the cancer is not actively growing or has responded well to treatment.
Coding Tips
- •Use this code only when documentation explicitly states the patient is in remission or has achieved complete or partial response
- •Do not use this code if there is any evidence of active disease or recurrence
Clinical Significance
Unspecified B-cell lymphoma in remission indicates a patient with a B-cell neoplasm that has responded to treatment but whose specific subtype was never fully characterized. Even in remission, these patients require ongoing surveillance with periodic imaging and laboratory monitoring. The unspecified nature of the B-cell subtype should prompt a query to determine if more specific classification is possible.
Documentation Requirements
- ✓Explicit provider documentation of 'remission' or 'complete response' — not just 'off treatment'
- ✓Original pathology report showing B-cell lineage (CD20+, CD19+, or other B-cell markers)
- ✓Date remission was achieved and method of assessment (PET/CT, bone marrow biopsy)
- ✓Surveillance plan including follow-up imaging and laboratory schedule
Commonly Confused Codes
Z85.79 (Personal history of other malignant neoplasms of lymphoid tissue) — Use history code when cancer is fully eradicated; use C85.1A when patient is in remission but still being monitoredC85.10 (Unspecified B-cell lymphoma, unspecified site) — C85.1A is specifically for remission status; C85.10 is for active disease with unknown siteC83.30-C83.3A (Diffuse large B-cell lymphoma) — If the B-cell subtype is known as DLBCL, use the specific C83.3 code series
