Recession of chamber angle, left eye

This code describes a condition where the drainage angle of the anterior chamber of the left eye has receded or widened, often due to trauma. This anatomical change can impair aqueous humor outflow, potentially leading to elevated intraocular pressure and secondary glaucoma.

Use this code when documentation specifies recession of the chamber angle in the left eye, typically identified during gonioscopy. This condition is frequently a sequela of blunt ocular trauma, even if the trauma occurred in the distant past.

• Ensure laterality is clearly documented as "left eye."
• Code any associated glaucoma or elevated intraocular pressure separately.
• Look for terms like "angle recession," "goniosynechiae," or "widened angle" in the context of a history of ocular injury.
