ICD-10 Code H44.122 – Parasitic endophthalmitis, unspecified, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.122 – Parasitic endophthalmitis, unspecified, left eye
What it is
This code identifies parasitic inflammation inside the left eye, affecting the vitreous or aqueous spaces. Use it when documentation names parasitic endophthalmitis and specifies the left eye, but does not identify the parasite.
Clinical signs
Typical findings include ocular pain, redness, decreased vision, and intraocular inflammation. Clinical features vary; refer to documentation, especially if the record confirms a parasitic cause without naming the organism.
When to use this code
Use H44.122 when the provider documents parasitic endophthalmitis in the left eye and does not specify the parasite species. It is also appropriate when the chart states “unspecified” parasitic endophthalmitis with left-eye laterality. Check documentation if the infection is described as another intraocular disorder.
Do not use for
Do not use this code for nonparasitic endophthalmitis, such as bacterial or fungal cases. Avoid it when the record identifies a different eye or another ocular inflammation diagnosis.
Coding tip
Confirm both laterality and the parasitic nature of the infection before assigning H44.122.
