ICD-10 Code H44.519 – Absolute Glaucoma, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.519 – Absolute glaucoma, unspecified eye
What it is
H44.519 identifies absolute glaucoma in an unspecified eye. It means the eye has end-stage glaucomatous damage with no useful vision remaining, but the record does not name the right or left eye.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe a blind eye with advanced optic nerve damage from glaucoma, often with severe visual field loss and a nonfunctional visual response.
When to use this code
Use this code when the provider documents absolute glaucoma and does not specify laterality. It fits end-stage glaucoma in an eye that is already functionally blind. If the note identifies the right or left eye, choose the laterality-specific code instead.
Do not use for
Do not use this code for suspected glaucoma, ocular hypertension, or glaucoma without end-stage loss of vision. Check documentation if the record describes a different glaucoma type or names a specific eye.
Coding tip
Always confirm that “absolute” reflects end-stage glaucoma, not just severe disease, and verify whether laterality is documented before assigning H44.519.
