Glaucoma sec to eye trauma, left eye, indeterminate stage

This code signifies elevated intraocular pressure and optic nerve damage in the left eye, directly resulting from a previous injury to the eye. The specific stage of glaucoma progression (e.g., mild, moderate, severe) cannot be determined from the available clinical documentation.

Apply this code when documentation clearly links glaucoma in the left eye to a history of ocular trauma, and the physician is unable to definitively stage the glaucoma. This is appropriate for cases where the extent of optic nerve damage or visual field loss is not yet fully assessed or is ambiguous.

• Ensure documentation explicitly states "left eye" and "indeterminate stage" for accurate coding.
• Do not use this code if the glaucoma stage is documented (e.g., mild, moderate, severe); instead, select the appropriate stage-specific code.
• Always sequence this code after the code for the underlying eye trauma, if the trauma is still being treated or is relevant to the current encounter.
