Non-billable headerICD-10-CM

I86 is a non-billable header ICD-10-CM code for varicose veins of other sites. 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.

varicose veins of unspecified site (I83.9-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

retinal varices (H35.0-)

I86 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 I86

6 child codes. Green means billable.
