Glaucoma secondary to eye trauma, bilateral, severe stage

This code signifies glaucoma that has developed in both eyes as a direct consequence of a past ocular injury, and has progressed to a severe stage. It indicates significant and irreversible damage to the optic nerve and visual field in both eyes due to the traumatic event.

Apply this code when documentation clearly states bilateral glaucoma secondary to eye trauma, with the severity explicitly noted as "severe stage." This typically involves advanced visual field loss, optic nerve cupping, and elevated intraocular pressure directly attributable to the trauma.

• Ensure documentation specifies bilateral involvement and a clear causal link between the trauma and the glaucoma.
• Verify the "severe stage" designation; avoid using this code for mild or moderate stages.
• Sequence this code after the initial injury code if the trauma is still being treated, or as a primary diagnosis if the glaucoma is the focus of the encounter.
