Glaucoma secondary to eye inflam, left eye, moderate stage

This code signifies elevated intraocular pressure and optic nerve damage in the left eye, specifically caused by an inflammatory process within the eye. The condition has progressed to a moderate stage, indicating a measurable degree of visual field loss or optic nerve damage beyond the early stages.

Apply this code when documentation clearly indicates glaucoma in the left eye resulting from uveitis, iritis, or other ocular inflammatory conditions. The medical record must also specify a moderate stage of the glaucoma, often supported by visual field testing or optic disc evaluation.

• Ensure the documentation explicitly links the glaucoma to an underlying inflammatory condition of the eye.
• Verify the laterality (left eye) and the stage (moderate) are clearly stated in the physician's notes.
• Code the underlying inflammatory condition (e.g., uveitis) first, followed by this code as a secondary diagnosis.
