H33.3 — Retinal breaks without detachment

Non-billable headerICD-10-CM

Excludes1 — never code together

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

chorioretinal scars after surgery for detachment (H59.81-)

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.

peripheral retinal degeneration without break (H35.4-)

Risk adjustment

H33.3 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 H33.3
