Non-billable headerICD-10-CM

H36 is a non-billable header ICD-10-CM code for retinal disorders in diseases classified elsewhere. 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.

arteriosclerotic retinopathy (H35.0-)
diabetic retinopathy (E08.3-, E09.3-, E10.3-, E11.3-, E13.3-)

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
lipid storage disorders (E75.-)
sickle-cell disorders (D57.-)

Risk adjustment

H36 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 H36

1 child code. Green means billable.
