Glaucoma sec to eye inflam, unsp eye, indeterminate stage

This code signifies glaucoma that has developed as a direct consequence of inflammation within the eye, without specifying which eye is affected. The stage of the glaucoma is not yet determined or cannot be classified. This condition involves increased intraocular pressure leading to optic nerve damage due to an underlying inflammatory process.

Use this code when documentation clearly links glaucoma to a preceding or co-existing ocular inflammatory condition, such as uveitis or iritis, but the specific eye (left or right) is not documented. It is appropriate when the physician has not yet staged the glaucoma or the stage is indeterminate. Supporting documentation should include a diagnosis of glaucoma secondary to inflammation and an absence of laterality or stage specification.

• Do not use this code if the laterality (left or right eye) is documented; instead, use the more specific H40.41X4 or H40.42X4.
• Avoid using this code if the stage of glaucoma (e.g., mild, moderate, severe, or absolute) is known; select a more specific code from the H40.4x category.
• Always code the underlying inflammatory condition first, followed by this code, to fully describe the patient's condition.
