Ocular hypertension, right eye

This code signifies elevated intraocular pressure (IOP) in the right eye without optic nerve damage or visual field loss. It indicates a risk factor for glaucoma rather than established glaucoma itself. The condition is typically asymptomatic and discovered during routine eye examinations.

Apply this code when documentation specifies elevated IOP in the right eye, and the ophthalmologist has ruled out glaucomatous changes. This is commonly used for patients undergoing monitoring for potential glaucoma development. Supporting documentation should include IOP readings and a statement confirming the absence of optic nerve damage or visual field defects.

• Do not use this code if there is any evidence of optic nerve damage or visual field loss; instead, code for glaucoma.
• Ensure laterality is clearly documented (right eye). If both eyes are affected, use the appropriate bilateral code or separate codes for each eye.
• Distinguish carefully between ocular hypertension and primary open-angle glaucoma suspect (H40.01-), as the latter implies a higher suspicion of developing glaucoma based on other risk factors.
