H05.3

H05.3 — Deformity of orbit

Non-billable headerICD-10-CM

H05.3 is a non-billable header ICD-10-CM code for deformity of orbit. 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.

congenital deformity of orbit (Q10.7)
hypertelorism (Q75.2)

Excludes1 inherited from the categories above H05.3

These are not written on H05.3, but they bind it: a note on a category applies to every code beneath it. Billing H05.3 with anything listed here is a denial.

Written on H05 — Disorders of orbit

congenital malformation of orbit (Q10.7)

Risk adjustment

H05.3 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 history

H05.3 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead H05.3
