S05.6 — Penetrating wound without foreign body of eyeball

Non-billable headerICD-10-CM

S05.6 is a non-billable header ICD-10-CM code for penetrating wound without foreign body of eyeball. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

Ocular penetration NOS

Excludes2 inherited from the categories above S05.6

Also inherited, and the opposite of Excludes1: these conditions are not part of S05.6, but a patient can have both, so you may code both.

Written on S05 — Injury of eye and orbit

2nd cranial [optic] nerve injury (S04.0-)
3rd cranial [oculomotor] nerve injury (S04.1-)
open wound of eyelid and periocular area (S01.1-)
orbital bone fracture (S02.1-, S02.3-, S02.8-)
superficial injury of eyelid (S00.1-S00.2)

Other codes that can never be billed with S05.6

These codes carry an Excludes1 note pointing at S05.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S05.6 alone.

H44.6Retained (old) intraocular foreign body, magnetic
H44.7Retained (old) intraocular foreign body, nonmagnetic
S00Superficial injury of head

Risk adjustment

S05.6 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

S05.6 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
