Microcystoid degeneration of retina, unspecified eye

This code signifies a degenerative condition of the retina characterized by the formation of small, fluid-filled cysts within the retinal layers. It represents a non-inflammatory process, often age-related, that can affect visual acuity if the macula is involved. This specific code indicates that the affected eye is not specified in the clinical documentation.

Utilize this code when the physician's documentation explicitly states "microcystoid degeneration of retina" without specifying laterality (e.g., right, left, or bilateral). Supporting documentation would include ophthalmic examination findings, such as optical coherence tomography (OCT) scans or funduscopic examination reports, confirming the presence of microcysts.

• Avoid using this code if laterality is documented; instead, select the appropriate code for right (H35.421), left (H35.422), or bilateral (H35.423) involvement.
• Do not confuse microcystoid degeneration with other retinal cystic conditions, such as retinoschisis (H35.7-) or macular edema (H35.3-).
• Ensure the documentation clearly distinguishes this condition from other forms of retinal degeneration.
