Cystoid macular degeneration, bilateral

This code signifies a condition characterized by the accumulation of fluid within the macula of both eyes, leading to cyst-like formations. This fluid buildup disrupts the normal architecture of the macula, which is responsible for sharp, central vision. It often results in blurred or distorted vision.

Apply this code when documentation clearly indicates cystoid macular degeneration affecting both eyes. This diagnosis is typically made through ophthalmic examination, including optical coherence tomography (OCT) scans demonstrating macular cysts. Use when the physician explicitly states "bilateral" involvement or documents findings consistent with the condition in both eyes.

• Ensure documentation specifies "bilateral" involvement; otherwise, a unilateral code may be more appropriate.
• Differentiate from other forms of macular degeneration, such as age-related macular degeneration (AMD), which has distinct ICD-10-CM codes.
• Look for supporting diagnostic imaging reports, particularly OCT, confirming the presence of macular cysts.
