0.000What This Code Means
A slow-growing cancer of lymph cells (follicular lymphoma, grade II) at an unspecified location in the body.
Coding Tips
- •Grade II follicular lymphoma has a slightly higher growth rate than grade I but is still considered indolent
- •Use this code only when the specific anatomical site of involvement is not documented; query the provider if possible
Clinical Significance
Follicular lymphoma grade II at an unspecified site represents intermediate-grade follicular lymphoma where the anatomic site of involvement is not documented. Grade II has a slightly more aggressive biology than grade I with 6-15 centroblasts per high-power field. This unspecified site code should prompt a query to the provider for site specification.
Documentation Requirements
- ✓Pathology report confirming follicular lymphoma grade II (6-15 centroblasts per HPF)
- ✓Query provider for specific anatomic site of involvement
- ✓Ann Arbor staging documentation
- ✓Current treatment status and plan
- ✓FLIPI prognostic score if available
Commonly Confused Codes
C82.00 — Grade I, unspecified site; verify pathology grade — grade I has 0-5 centroblasts, grade II has 6-15C82.20 — Grade III unspecified, unspecified site; grade III has >15 centroblasts and different treatment implicationsC82.11-C82.19 — Site-specific grade II codes; always prefer these over C82.10 when site is documentedC85.10 — Unspecified non-Hodgkin lymphoma, unspecified site; use when subtype is not yet determined
