Absolute glaucoma, unspecified eye

This code signifies the end-stage of glaucoma, characterized by complete and irreversible vision loss, often accompanied by severe pain, and a non-functional eye. The eye typically appears blind and painful, with elevated intraocular pressure.

Apply this code when documentation clearly indicates absolute glaucoma in an unspecified eye, meaning the laterality (right or left) is not specified. This diagnosis is typically made after extensive evaluation and confirmation of total vision loss due to glaucoma.

• Avoid using this code if laterality is documented; instead, choose the specific eye code (H44.511 or H44.512).
• Ensure the medical record explicitly states "absolute glaucoma" or describes a blind, painful eye due to end-stage glaucoma.
• Do not confuse with other severe glaucoma codes that still retain some vision.
