ICD-10 Code H44.129 – Parasitic endophthalmitis, unspecified, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.129 – Parasitic endophthalmitis, unspecified, unspecified eye
What it is
This code identifies parasitic inflammation inside the eye when the organism and the affected eye are not specified. Use it for documented endophthalmitis caused by a parasite, but with incomplete laterality or species detail.
Clinical signs
Typical findings include intraocular inflammation, pain, redness, and reduced vision. Clinical features vary; refer to documentation, especially when the record confirms a parasitic cause but does not name the parasite or eye.
When to use this code
Use H44.129 when the provider documents parasitic endophthalmitis and does not specify right, left, or bilateral eye. It also fits when the chart confirms parasitic infection within the eye, but the organism is not identified. Check documentation if another ocular infection or inflammatory disorder is described instead.
Do not use for
Do not use this code for nonparasitic endophthalmitis, such as postoperative or bacterial cases. Also avoid it when the record specifies the eye or a different diagnosis more accurately.
Coding tip
If the note names the parasite or laterality, code the documented specificity rather than H44.129.
