ICD-10 Code H44.013 – Panophthalmitis (acute), bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.013 – Panophthalmitis (acute), bilateral
What it is
H44.013 identifies acute panophthalmitis affecting both eyes. This is a severe, full-thickness inflammatory infection of the eye that involves intraocular structures and surrounding tissues.
Clinical signs
Typical findings include marked eye pain, redness, swelling, and decreased vision. Clinical features vary; refer to documentation for evidence of bilateral acute panophthalmitis.
When to use this code
Use this code when the record clearly documents acute panophthalmitis in both eyes. It may also fit when the provider states bilateral involvement of the globe and surrounding ocular tissues. If laterality is unclear or the condition is not acute, check documentation.
Do not use for
Do not use this code for unilateral panophthalmitis, chronic eye inflammation, or nonspecific orbital infection. Check documentation when the note only describes conjunctivitis, keratitis, or endophthalmitis without panophthalmitis.
Coding tip
Confirm both acuity and bilateral laterality in the provider note before assigning H44.013.
