Age-related choroidal atrophy, right eye

This code signifies a specific type of age-related degeneration affecting the choroid, the vascular layer of the eye, in the right eye. This atrophy involves the thinning and loss of choroidal tissue, distinct from retinal or macular degeneration.

Apply this code when documentation explicitly states age-related choroidal atrophy affecting the right eye. This diagnosis is typically made by an ophthalmologist based on funduscopic examination, optical coherence tomography (OCT), or fluorescein angiography findings.

• Ensure documentation specifies "age-related" and clearly identifies the "right eye."
• Do not confuse with age-related macular degeneration (AMD) codes (H35.3x), as choroidal atrophy is a distinct condition.
• Consider laterality; separate codes exist for the left eye (H31.112) and bilateral involvement (H31.113).
