Buddy Documentation Tip

HCC Buddy guidance
Pathology confirming Hodgkin lymphoma classified as 'other' subtype
Imaging (CT or PET/CT) documenting intrapelvic lymph node involvement
Distinction from inguinal nodes (superficial) and intra-abdominal nodes (above pelvic brim)
Staging documentation

Audit Caution

HCC Buddy guidance
Miscoding intrapelvic as inguinal or intra-abdominal — verify the anatomic location on imaging
Using unspecified subtype code when pathology has classified the variant
Not capturing the intrapelvic specificity when it is documented on imaging
Defaulting to unspecified site code when pelvic imaging has been performed

Common Mistakes

HCC Buddy guidance
C81.75 — Other Hodgkin lymphoma, inguinal/lower limb: inguinal is superficial groin; intrapelvic is deep within the pelvic cavity
C81.73 — Other Hodgkin lymphoma, intra-abdominal: above the pelvic brim is abdominal; below is pelvic
C81.96 — Hodgkin lymphoma, unspecified, intrapelvic: use C81.76 when the subtype is confirmed as 'other'

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 C81.76 an HCC code?

Yes. C81.76 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).

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 C81.76

For C81.76to 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 C81.76 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

C81.76 is the ICD-10-CM diagnosis code for other hodgkin lymphoma, intrapelvic lymph nodes. A less common type of Hodgkin lymphoma affecting lymph nodes inside the pelvis. C81.76 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, C81.76 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, C81.76 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 intrapelvic involvement on imaging; pelvic ultrasound or CT is typically used. Because C81.76 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 C81.76 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • Verify intrapelvic involvement on imaging; pelvic ultrasound or CT is typically used
  • Distinguish from inguinal nodes; intrapelvic refers to nodes within the pelvic cavity

Clinical Significance

Other Hodgkin lymphoma of intrapelvic lymph nodes is a rare presentation combining an uncommon subtype with a deep anatomic location. Intrapelvic nodes are not palpable and are typically identified only on cross-sectional imaging. This location may complicate treatment planning due to proximity to pelvic organs and the need to balance radiation field design with organ preservation.

Documentation Requirements

  • Pathology confirming Hodgkin lymphoma classified as 'other' subtype
  • Imaging (CT or PET/CT) documenting intrapelvic lymph node involvement
  • Distinction from inguinal nodes (superficial) and intra-abdominal nodes (above pelvic brim)
  • Staging documentation
  • Treatment planning considerations for the pelvic location

Commonly Confused Codes

  • C81.75 — Other Hodgkin lymphoma, inguinal/lower limb: inguinal is superficial groin; intrapelvic is deep within the pelvic cavity
  • C81.73 — Other Hodgkin lymphoma, intra-abdominal: above the pelvic brim is abdominal; below is pelvic
  • C81.96 — Hodgkin lymphoma, unspecified, intrapelvic: use C81.76 when the subtype is confirmed as 'other'
