ICD-10 Code H44.123 – Parasitic endophthalmitis, unspecified, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.123 – Parasitic endophthalmitis, unspecified, bilateral
What it is
This code identifies parasitic inflammation inside both eyes, with the parasite type not specified. Use it when documentation confirms bilateral endophthalmitis caused by a parasite, but does not name the organism.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note bilateral ocular inflammation, pain, redness, blurred vision, or decreased visual acuity, but you should code only what is documented.
When to use this code
Use H44.123 when the provider documents parasitic endophthalmitis affecting both eyes and does not identify a specific parasite. It also fits when the record states “unspecified” or gives insufficient detail for a more specific code. Check documentation if laterality or cause is unclear.
Do not use for
Do not use this code for nonparasitic endophthalmitis, uveitis, or other intraocular inflammation without parasitic cause. If the condition is unilateral or the parasite is specified, select the more accurate code.
Coding tip
Confirm both laterality and parasitic cause in the chart before assigning H44.123.
