D49.8 — Neoplasm of unspecified behavior of other specified sites

Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Other codes that can never be billed with D49.8
These codes carry an Excludes1 note pointing at D49.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D49.8 alone.

D49.8 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.
