C84.7 — Anaplastic large cell lymphoma, ALK-negative
C84.7 is a non-billable header ICD-10-CM code for anaplastic large cell lymphoma, alk-negative. It cannot be billed on its own: choose one of the more specific child codes below.
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-)
Other codes that can never be billed with C84.7
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
Risk adjustment
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
