ICD-10 Code H44.12 – Parasitic endophthalmitis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.12 – Parasitic endophthalmitis, unspecified
What it is
H44.12 identifies endophthalmitis caused by a parasitic infection when the organism is not further specified. Use it for intraocular inflammation involving the eye’s internal fluids or tissues, with parasitic cause documented but no more detail available.
Clinical signs
Clinical features vary; refer to documentation. Commonly, endophthalmitis may present with eye pain, redness, decreased vision, floaters, or marked intraocular inflammation noted on exam.
When to use this code
Use this code when the provider documents parasitic endophthalmitis and does not name the parasite or provide a more specific category. It also fits cases where the chart confirms intraocular infection or inflammation due to a parasite, but details are limited. Check documentation if laterality or organism is specified elsewhere.
Do not use for
Do not use H44.12 for noninfectious uveitis, external eye infections, or endophthalmitis from bacterial or fungal causes. If the record identifies a specific parasite or another cause, code that documented condition instead.
Coding tip
Verify that the note explicitly links the endophthalmitis to a паразitic cause before assigning this code.
