H31.1 — Choroidal degeneration
H31.1 is a non-billable header ICD-10-CM code for choroidal degeneration. 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.
- angioid streaks of macula (H35.33)
Other codes that can never be billed with H31.1
These codes carry an Excludes1 note pointing at H31.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H31.1 alone.
- H35.5Hereditary retinal dystrophy
Risk adjustment
H31.1 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 H31.1
