About H44.00
H44.00 is the ICD-10-CM diagnosis code for unspecified purulent endophthalmitis. It belongs to category H44 (disorders of globe), block H43-H44 (disorders of vitreous body and globe) 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 H44.0, choose H44.00 (Unspecified purulent endophthalmitis) only when documentation doesn't support a more specific option: Panophthalmitis (acute) (H44.01) and vitreous abscess (chronic) (H44.02).
To report this condition, pick the subcode that matches the documentation: H44.001 (right eye), H44.002 (left eye), H44.003 (bilateral) and H44.009 (unspecified eye).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
