ICD-10 Code H44.019 – Panophthalmitis (acute), unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.019 – Panophthalmitis (acute), unspecified eye
What it is
H44.019 identifies acute panophthalmitis in an unspecified eye. It means severe, diffuse inflammation involving the entire eye, including intraocular tissues and surrounding structures.
Clinical signs
Typical findings include marked eye pain, redness, swelling, and decreased vision. Clinical features vary; refer to documentation if the record does not clearly describe acute, whole-eye involvement.
When to use this code
Use this code when the provider documents acute panophthalmitis and does not specify right or left eye. It is also appropriate when the note clearly supports panophthalmitis but laterality is missing. Check documentation if the record only says ocular infection or inflammation without confirming panophthalmitis.
Do not use for
Do not use this code for endophthalmitis, orbital cellulitis, or other localized eye infections unless panophthalmitis is specifically documented. Do not assign it when the eye laterality is documented.
Coding tip
Confirm both acuity and laterality in the chart before coding; if either is unclear, query the provider or use the documented specificity only.
