Non-billable headerICD-10-CM

H35 is a non-billable header ICD-10-CM code for other retinal disorders. It cannot be billed on its own: choose one of the more specific child codes below.

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.

diabetic retinal disorders (E08.311-E08.359, E09.311-E09.359, E10.311-E10.359, E11.311-E11.359, E13.311-E13.359)

Other codes that can never be billed with H35

These codes carry an Excludes1 note pointing at H35. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H35 alone.

Risk adjustment

H35 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 H35

10 child codes. Green means billable.
