About H59.21

H59.21 is the ICD-10-CM diagnosis code for accidental puncture and laceration of eye and adnexa during an ophthalmic procedure. It belongs to category H59 (intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified), block H59 (intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within H59.2 (accidental puncture and laceration of eye and adnexa during a procedure), H59.21 is specifically for accidental puncture and laceration of eye and adnexa during an ophthalmic procedure. Related codes cover other procedure (H59.22).

To report this condition, pick the subcode that matches the documentation: H59.211 (procedure), H59.212 (procedure), H59.213 (bilateral) and H59.219 (procedure).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
