Recession of chamber angle, right eye

This code describes a condition where the drainage angle of the anterior chamber of the right eye has receded or widened, often due to trauma. This recession can impair aqueous humor outflow, potentially leading to elevated intraocular pressure and glaucoma. It is a structural alteration of the anterior chamber angle.

Use this code when documentation clearly indicates a diagnosis of recession of the chamber angle affecting the right eye. This diagnosis is typically made following gonioscopy, which visualizes the anterior chamber angle, and often in patients with a history of ocular trauma. Supporting documentation should specify the affected eye.

• Ensure laterality is accurately documented (right eye).
• Consider co-reporting with codes for associated conditions, such as secondary glaucoma (e.g., H40.3x) if present.
• Distinguish from other angle abnormalities like synechiae or angle closure, which have different ICD-10-CM codes.
