0.000What This Code Means
A type of non-Hodgkin lymphoma affecting follicle center cells that is currently in remission (no active disease).
Coding Tips
- •Only assign this code when remission status is explicitly documented by the physician
- •Verify the duration and type of remission (complete vs. partial) if available
Clinical Significance
Diffuse follicle center lymphoma in remission indicates the disease has responded to treatment with no current evidence of active disease. Despite remission, patients require ongoing surveillance due to the risk of relapse. This code continues to capture the cancer diagnosis for risk adjustment purposes because the patient remains under active oncologic management. Documentation of remission type (complete vs. partial) and surveillance plan is essential for ongoing clinical management.
Documentation Requirements
- ✓Physician documentation explicitly stating remission status
- ✓Most recent imaging (PET/CT) confirming no active disease
- ✓Type of remission documented (complete response vs. partial response)
- ✓Date remission was achieved
- ✓Ongoing surveillance schedule and monitoring plan
- ✓Any maintenance therapy being administered
Commonly Confused Codes
C82.50 — Diffuse follicle center lymphoma, unspecified site: Use C82.50 for active disease; use C82.5A when in remissionZ85.72 — Personal history of non-Hodgkin lymphomas: Use Z85.72 only when treatment is fully completed with no ongoing surveillance; C82.5A is for active remission under monitoringC82.4A — Follicular lymphoma grade IIIb, in remission: Different histologic subtype — verify pathology
