ICD-10 Code H44.001 – Unspecified purulent endophthalmitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.001 – Unspecified purulent endophthalmitis, right eye
What it is
This code identifies a purulent infection inside the right eye when the provider does not specify the cause. It indicates severe intraocular inflammation with pus, limited to the right eye.
Clinical signs
Typical findings include eye pain, redness, decreased vision, and marked intraocular inflammation. Clinical features vary; refer to documentation.
When to use this code
Use H44.001 when documentation states purulent endophthalmitis in the right eye and does not name an organism or other cause. Apply it only when the right eye is clearly identified. If the record later specifies the etiology, code the more specific diagnosis instead.
Do not use for
Do not use this code for endophthalmitis of the left eye, both eyes, or unspecified eye. Do not use it when the chart describes a nonpurulent eye infection or another ocular inflammatory disorder.
Coding tip
Check whether the provider documented the eye laterality and any specific cause before assigning the unspecified code.
