S05.00XA — Injury of conjunctiva and corneal abrasion without foreign body, unspecified eye, initial encounter
S05.00XA is a billable, specific ICD-10-CM code for injury of conjunctiva and corneal abrasion without foreign body, unspecified eye, initial encounter. It is valid for submission on a claim.
7th character "A" — initial encounter
The appropriate 7th character is to be added to each code from category S05
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 inherited from the categories above S05.00XA
These are not written on S05.00XA, but they bind it: a note on a category applies to every code beneath it. Billing S05.00XA with anything listed here is a denial.
Excludes2 inherited from the categories above S05.00XA
Also inherited, and the opposite of Excludes1: these conditions are not part of S05.00XA, but a patient can have both, so you may code both.
Other codes that can never be billed with S05.00XA
These codes carry an Excludes1 note pointing at S05.00XA. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S05.00XA alone.
Risk adjustment
S05.00XA 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
S05.00XA has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
