C81.4 — Lymphocyte-rich Hodgkin lymphoma

Non-billable headerICD-10-CM

These are not written on C81.4, but they bind it: a note on a category applies to every code beneath it. Billing C81.4 with anything listed here is a denial.

Other codes that can never be billed with C81.4

These codes carry an Excludes1 note pointing at C81.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C81.4 alone.

C26.1Malignant neoplasm of spleen

Risk adjustment

C81.4 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

C81.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead C81.4
