Glaucoma secondary to eye trauma, left eye, mild stage

This code signifies elevated intraocular pressure and optic nerve damage in the left eye, directly resulting from a past or present ocular injury. The condition is in its early stages, indicating minimal vision loss or optic nerve damage.

Apply this code when documentation confirms glaucoma in the left eye, explicitly attributed to a traumatic event affecting the eye, and the severity is classified as mild. Supporting documentation should clearly link the glaucoma to a specific eye trauma and specify the left eye and mild stage.

• Always code the underlying eye trauma first, if still active, followed by this code.
• Ensure the documentation specifies "left eye" and "mild stage" to avoid using a less specific or incorrect laterality/stage code.
• Differentiate from other secondary glaucomas (e.g., inflammatory, drug-induced) by confirming the traumatic etiology.
