Glaucoma secondary to eye trauma, unsp eye, stage unsp

This code signifies elevated intraocular pressure and optic nerve damage resulting from a previous injury to the eye. It indicates a form of secondary glaucoma where the specific eye affected and the severity of the condition are not documented.

Apply this code when documentation clearly links glaucoma to a history of ocular trauma, but the medical record does not specify whether the right or left eye is affected, nor does it provide information about the glaucoma's stage (e.g., mild, moderate, severe, indeterminate). This is appropriate when the physician notes "post-traumatic glaucoma, unspecified eye."

• Avoid using this code if the affected eye (right or left) is documented; instead, select a more specific code from the H40.3- series.
• Do not use this code if the stage of glaucoma is known; choose a code that specifies the stage.
• Always sequence a code for the underlying eye trauma (e.g., S05.- series) if it is still relevant to the current encounter and not fully resolved.
