S05.0 vs T15.1

S05.0 (Injury of conjunctiva and corneal abrasion without foreign body) compared with T15.1 (Foreign body in conjunctival sac), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.

Can these codes be reported together?

No — do not report together. S05.0 carries an Excludes1 note covering T15.1: “foreign body in conjunctival sac (T15.1)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Yes, when both are documented. S05.0 carries an Excludes2 note covering T15.1: “effects of foreign body on external eye (T15.-)”

Excludes2 marks distinct conditions — both may be reported when both are documented.
