H35.2 — Other non-diabetic proliferative retinopathy

Non-billable headerICD-10-CM

H35.2 is a non-billable header ICD-10-CM code for other non-diabetic proliferative retinopathy. 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.

proliferative vitreo-retinopathy with retinal detachment (H33.4-)

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.

proliferative sickle-cell retinopathy (H36.82-)

Inclusion terms

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

Proliferative vitreo-retinopathy
Thalassemia proliferative retinopathy

Risk adjustment

H35.2 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.

How H35.2 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to H35.2.

Retinopathy›proliferative NEC›thalassemia

Code to one of these instead H35.2

4 child codes. Green means billable.
