About H05

H05 is the ICD-10-CM diagnosis code for disorders of orbit. It belongs to block H00-H05 (disorders of eyelid, lacrimal system and orbit) 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H05.0 (orbit), H05.1 (orbit), H05.2 (conditions), H05.3 (orbit), H05.4 (enophthalmos), H05.5 (orbit), H05.8 (orbit) and H05.9 (orbit).

Don't report H05 together with the conditions in its Excludes1 note: congenital malformation of orbit (Q10.7).

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