About H44.12
H44.12 is the ICD-10-CM diagnosis code for parasitic endophthalmitis, unspecified. 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 H44.1, choose H44.12 (Parasitic endophthalmitis, unspecified) only when documentation doesn't support a more specific option: Panuveitis (H44.11), sympathetic uveitis (H44.13) and other endophthalmitis (H44.19).
To report this condition, pick the subcode that matches the documentation: H44.121 (right eye), H44.122 (left eye), H44.123 (bilateral) and H44.129 (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.
