Excludes1 — never code together

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

personal history of venous embolism and thrombosis (Z86.718)

Use additional code

Add a secondary code to capture the detail described below.

code, if applicable, for associated long-term (current) use of anticoagulants (Z79.01)

Risk adjustment

I82.5 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 I82.5

10 child codes. Green means billable.
