Ocular hypertension, bilateral

This code signifies elevated intraocular pressure (IOP) in both eyes without evidence of optic nerve damage or visual field loss. It represents a risk factor for developing primary open-angle glaucoma.

Apply this code when documentation explicitly states ocular hypertension affecting both eyes, typically identified during routine ophthalmic examinations or screenings. Supporting documentation includes tonometry readings indicating elevated IOP (e.g., >21 mmHg) in both eyes, coupled with normal optic nerve appearance and visual fields.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Do not use this code if there is any evidence of optic nerve damage or visual field defects, as this would indicate glaucoma.
• This code is often a primary diagnosis when monitoring patients at risk for glaucoma.
