About H05.02
H05.02 is the ICD-10-CM diagnosis code for osteomyelitis 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 4 subcodes must be used instead.
Within H05.0 (acute inflammation of orbit), H05.02 is specifically for osteomyelitis of orbit. Related codes cover unspecified acute inflammation of orbit (H05.00), cellulitis of orbit (H05.01), periostitis of orbit (H05.03) and tenonitis of orbit (H05.04).
To report this condition, pick the subcode that matches the documentation: H05.021 (orbit), H05.022 (orbit), H05.023 (orbits) and H05.029 (orbit).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
