Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • primary cutaneous CD30-positive T-cell proliferations (C86.6-)

These codes carry an Excludes1 note pointing at C84.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C84.7 alone.

  • C86Other specified types of T/NK-cell lymphoma

C84.7 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 to one of these instead C84.7
