Glaucoma sec to oth eye disord, bi, indeterminate stage

This code signifies elevated intraocular pressure and optic nerve damage in both eyes, resulting from another underlying ocular condition. The specific stage of glaucoma progression is unknown or cannot be determined.

Apply this code when documentation clearly indicates bilateral glaucoma caused by a co-existing eye disorder (e.g., uveitis, retinal detachment, intraocular tumor) and the physician cannot definitively assign a stage (e.g., mild, moderate, severe). This code is appropriate when the medical record explicitly states "indeterminate stage" or provides insufficient information to classify the stage.

• Always code the underlying eye disorder first, followed by this glaucoma code.
• Do not use this code if the stage of glaucoma is known; instead, select the appropriate code specifying the stage (e.g., H40.51X1-H40.51X4 for mild, moderate, severe, or unspecified stage).
• Ensure documentation specifies "bilateral" and "indeterminate stage" for accurate code assignment.
