Goniosynechiae, unspecified eye

This code describes the presence of goniosynechiae, which are adhesions between the iris and the trabecular meshwork in the anterior chamber angle of the eye. These adhesions can impede aqueous humor outflow, potentially leading to increased intraocular pressure and glaucoma. This specific code is used when the affected eye is not specified.

Use this code when documentation confirms the presence of goniosynechiae but does not specify laterality (e.g., "goniosynechiae noted"). This diagnosis is often made during gonioscopy. Supporting documentation should clearly state the finding of goniosynechiae without indicating whether it's in the right, left, or both eyes.

• Avoid using this code if laterality is documented; instead, choose the more specific codes for right (H21.521), left (H21.522), or bilateral (H21.523) goniosynechiae.
• Always review the entire clinical note for any mention of laterality before defaulting to an "unspecified" code.
• Consider co-reporting with codes for associated conditions like glaucoma (e.g., H40.xx) if present and documented.
