Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.

Inclusion terms
Alternative wordings a physician may use in the chart for this same code.

Other codes that can never be billed with D31.6
These codes carry an Excludes1 note pointing at D31.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D31.6 alone.
Risk adjustment
D31.6 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 D31.6
