H44.6 vs S05.5
H44.6 (Retained (old) intraocular foreign body, magnetic) compared with S05.5 (Penetrating wound with foreign body of eyeball), 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. H44.6 carries an Excludes1 note covering S05.5: “current intraocular foreign body (S05.-)”
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. S05.5 carries an Excludes2 note covering H44.6: “retained (old) intraocular foreign body (H44.6-, H44.7)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
