H05.3Deformity of orbit

H05.3 is the ICD-10-CM diagnosis code for deformity of orbit. It belongs to category H05 (disorders of orbit), 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 6 subcodes must be used instead.

Within H05 (disorders of orbit), H05.3 is specifically for deformity of orbit. Related codes cover acute inflammation of orbit (H05.0), chronic inflammatory disorders of orbit (H05.1), Exophthalmic conditions (H05.2), enophthalmos (H05.4), retained (old) foreign body following penetrating wound of orbit (H05.5), other disorders of orbit (H05.8) and unspecified disorder of orbit (H05.9).

To report this condition, pick the subcode that matches the documentation: H05.30 (orbit), H05.31 (orbit), H05.32 (due to bone disease), H05.33 (due to trauma or surgery), H05.34 (orbit) and H05.35 (orbit).

Don't report H05.3 together with the conditions in its Excludes1 note: congenital deformity of orbit (Q10.7) and hypertelorism (Q75.2).

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