Glaucoma secondary to eye inflam, unsp eye, severe stage

This code signifies a severe form of glaucoma that has developed as a direct consequence of inflammation within the eye. It indicates significant and irreversible damage to the optic nerve and visual field loss due to elevated intraocular pressure, where the specific eye affected is not documented.

Apply this code when documentation clearly states a diagnosis of glaucoma secondary to uveitis, iritis, or other ocular inflammatory conditions, and specifies a severe stage of the disease. This code is appropriate when the medical record does not specify whether the left or right eye is affected.

• Ensure the documentation explicitly links the glaucoma to an underlying inflammatory process.
• Verify the severity of the glaucoma is documented as "severe" to support this specific stage.
• Avoid using this code if the laterality (left or right eye) is known; instead, use the more specific H40.41X3 or H40.42X3.
