Preglaucoma, unspecified, right eye

This code signifies a pre-glaucomatous condition affecting the right eye, where the specific type of pre-glaucoma is not documented. It indicates the presence of risk factors for developing glaucoma, such as elevated intraocular pressure (ocular hypertension) or suspicious optic nerve appearance, without definitive signs of glaucomatous damage.

Use this code when documentation indicates a pre-glaucoma diagnosis in the right eye, but the specific type (e.g., ocular hypertension, primary open-angle suspect) is not specified. It is appropriate for patients undergoing monitoring for glaucoma development due to risk factors. Supporting documentation should clearly state "preglaucoma, right eye" without further specificity.

• Do not use this code if a more specific pre-glaucoma diagnosis (e.g., H40.011 for ocular hypertension) is documented.
• Ensure laterality is clearly documented for the right eye; otherwise, an unspecified laterality code may be more appropriate.
• This code typically precedes the development of actual glaucoma (H40.xx) and should not be used if glaucomatous damage is confirmed.
