Glaucoma secondary to eye trauma, unsp eye, mild stage

This code signifies an increase in intraocular pressure and optic nerve damage resulting from a previous injury to the eye. The condition is in its early stages, indicating minimal visual field loss and optic nerve changes.

Apply this code when documentation clearly links glaucoma development to a history of eye trauma, and the physician specifies a "mild" stage. This is appropriate for patients presenting with early signs of secondary glaucoma following an ocular injury.

• Always confirm the causal link between the trauma and the glaucoma.
• Ensure the documentation specifies "mild stage" for this particular code.
• Do not use this code for glaucoma due to other secondary causes (e.g., inflammation, drugs); refer to other H40.xx codes.
