Billable

Anterior synechiae (iris), bilateral

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Scar tissue adhesion between the iris and the cornea (front of the eye) in both eyes. This restricts the iris from moving normally and can affect vision and eye pressure in both eyes.

Coding Tips

  • •Confirm documentation clearly indicates bilateral anterior synechiae
  • •Document the underlying cause (uveitis, trauma, surgery) if present, as this may affect treatment planning
