H35.423

What This Code Means

This condition involves the development of tiny fluid-filled sacs in the retina (the light-sensitive tissue at the back of the eye) that affect both eyes. It is a degenerative eye condition that can impact vision over time.

Coding Tips

• •Verify that the condition is documented as bilateral (affecting both eyes) before assigning this code; if only one eye is affected, use the unilateral code H35.421 instead
• •This code is typically used for chronic retinal conditions identified during ophthalmologic examination; ensure the documentation clearly describes microcystoid degeneration rather than other retinal cyst types
