Glaucoma secondary to eye trauma, left eye, stage unsp

This code signifies elevated intraocular pressure and optic nerve damage in the left eye, directly resulting from a previous traumatic injury to the eye. The specific stage of glaucoma progression is not documented or determined.

Apply this code when the patient's medical record clearly links the development of glaucoma in the left eye to a past ocular trauma. Documentation should specify "left eye" and indicate that the glaucoma is a direct consequence of the injury, without specifying the stage of the condition.

• Ensure documentation explicitly states "left eye" and "secondary to trauma."
• Do not use if the trauma is not the direct cause of the glaucoma, or if the glaucoma is congenital or primary.
• If the stage of glaucoma is known, a more specific code from the H40.32 category should be used.
