What is ICD-10 code C82.69?

C82.69 is the ICD-10-CM diagnosis code for Cutaneous follicle center lymphoma, extranodal and solid organ sites. It belongs to the ICD-10-CM chapter for neoplasms (c00-d49). C82.69 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. C82.69 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. C82.69 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. C82.69 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

What is the V28 vs V24 difference for C82.69?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. For C82.69, V28 maps to Lymphoma and Other Cancers at RAF 0.671 while V24 mapped to Lymphoma and Other Cancers at RAF 0.675. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting C82.69?

Verify documentation specifies both the cutaneous (skin) location AND extranodal/solid organ involvement to justify this specific code rather than C82.60 (nodal sites only) Identify and document which specific extranodal or solid organ sites are affected, as this information supports medical necessity and may be required for staging and treatment planning Because C82.69 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Cutaneous follicle center lymphoma, extranodal and solid organ sites

This is a type of skin cancer (lymphoma) that starts in hair follicles and has spread to organs or tissues outside the lymph nodes. It is a slow-growing cancer that primarily affects the skin but may involve other body sites.

Buddy Insight

Cutaneous follicle center lymphoma involving extranodal and solid organ sites represents the most advanced presentation of what is typically an indolent primary skin lymphoma.

Original skin biopsy confirming cutaneous follicle center lymphoma diagnosis

Multidisciplinary pathology review confirming the primary cutaneous designation

Audit Caution

HCC Buddy guidance

Maintaining a cutaneous primary classification when extranodal spread to solid organs is present — this pattern almost always represents systemic disease

Not ensuring biopsy confirmation of extranodal organ involvement

Coding extranodal sites without documenting which specific organs are affected

Failing to reclassify as systemic follicular lymphoma when clinical behavior is inconsistent with cutaneous type

Common Mistakes

HCC Buddy guidance

C82.59 — Diffuse follicle center lymphoma, extranodal and solid organ sites: Systemic disease is far more likely with extranodal involvement

C82.89 — Other types of follicular lymphoma, extranodal and solid organ sites: Different follicular subtype

C82.68 — Cutaneous follicle center lymphoma, lymph nodes of multiple sites: Nodal vs. extranodal distinction

Is C82.69 an HCC code?

Yes. C82.69 (Cutaneous follicle center lymphoma, extranodal and solid organ sites) maps to Lymphoma and Other Cancers under the CMS-HCC V28 risk adjustment model (and Lymphoma and Other Cancers under V24), with a community non-dual aged RAF of 0.671. It is billable for payment year 2026.

Coder answer: C82.69 is billable and maps to V28 HCC 21, Lymphoma and Other Cancers. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. 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 C82.69

For C82.69 to 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 C82.69 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

C82.69 is the ICD-10-CM diagnosis code for cutaneous follicle center lymphoma, extranodal and solid organ sites. This is a type of skin cancer (lymphoma) that starts in hair follicles and has spread to organs or tissues outside the lymph nodes. It is a slow-growing cancer that primarily affects the skin but may involve other body sites. C82.69 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, C82.69 maps to Lymphoma and Other Cancers (HCC 21) with a community, non-dual, aged base RAF weight of 0.671. Under the older V24 model, C82.69 mapped to the same category but with a base RAF weight of 0.675, V28 recalibrated weights across the entire model. 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 both the cutaneous (skin) location AND extranodal/solid organ involvement to justify this specific code rather than C82.60 (nodal sites only). Because C82.69 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 C82.69 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Verify documentation specifies both the cutaneous (skin) location AND extranodal/solid organ involvement to justify this specific code rather than C82.60 (nodal sites only)
•Identify and document which specific extranodal or solid organ sites are affected, as this information supports medical necessity and may be required for staging and treatment planning

Clinical Significance

Cutaneous follicle center lymphoma involving extranodal and solid organ sites represents the most advanced presentation of what is typically an indolent primary skin lymphoma. Involvement of solid organs (liver, bone marrow, lungs, GI tract) in the setting of a primary cutaneous lymphoma is extremely rare and should prompt thorough reassessment of the diagnosis. This may actually represent systemic follicular lymphoma with cutaneous involvement rather than the reverse.

Documentation Requirements

✓Original skin biopsy confirming cutaneous follicle center lymphoma diagnosis
✓Documentation of specific extranodal organs involved with biopsy confirmation
✓Multidisciplinary pathology review confirming the primary cutaneous designation
✓Complete staging evaluation with PET/CT and bone marrow biopsy
✓Clinical justification for maintaining cutaneous primary classification
✓Assessment of organ function at involved extranodal sites

Commonly Confused Codes
