Buddy Insight
Cutaneous follicle center lymphoma involving the spleen is a very unusual presentation that should strongly prompt reconsideration of the primary cutaneous diagnosis.

Common Mistakes
Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.
Is C82.67 an HCC code?
Yes. C82.67 maps to Breast, Prostate, Colorectal and Other Cancers and Tumors under the CMS-HCC V28 risk adjustment model (and Lymphoma and Other Cancers under V24).
HCC Category Mapping
RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.
MEAT Criteria for C82.67
For C82.67to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed C82.67 during that encounter, not just copy-forwarded from a problem list.
What This Code Means
C82.67 is the ICD-10-CM diagnosis code for cutaneous follicle center lymphoma, spleen. A type of lymphoma (blood cancer) that starts in the skin and affects the spleen, characterized by abnormal growth of follicle center cells. C82.67 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering malignant neoplasms of lymphoid, hematopoietic and related tissue (c81-c96).
Under the CMS-HCC V28 risk adjustment model, C82.67 maps to Breast, Prostate, Colorectal and Other Cancers and Tumors (HCC 21) with a community, non-dual, aged base RAF weight of 0.545. Under the older CMS-HCC V24 model, C82.67 maps to Lymphoma and Other Cancers (HCC 10) with a community, non-dual, aged base RAF weight of 0.675. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Verify documentation specifies cutaneous (skin) involvement and spleen location before assigning this code. Because C82.67 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for C82.67 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies cutaneous (skin) involvement and spleen location before assigning this code
- •Check for remission status - if patient is in remission, use C82.6A instead
Clinical Significance
Cutaneous follicle center lymphoma involving the spleen is a very unusual presentation that should strongly prompt reconsideration of the primary cutaneous diagnosis. Splenic involvement implies disseminated disease that is more consistent with systemic follicular lymphoma. If the primary cutaneous designation is maintained, comprehensive staging and pathologic review should document why the cutaneous classification remains appropriate despite this unusual spread pattern.
Documentation Requirements
- ✓Original skin biopsy confirming cutaneous follicle center lymphoma
- ✓Imaging documenting splenic involvement (splenomegaly, focal lesions)
- ✓Clinical rationale for maintaining cutaneous primary classification despite splenic disease
- ✓Pathology review confirming diagnosis concordance
- ✓Complete staging evaluation
- ✓Hematologic assessment for cytopenias related to splenic disease
