Billable

Goniosynechiae, bilateral

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

What This Code Means

Adhesions between the iris and the drainage angle affecting both eyes, potentially impacting fluid drainage in both eyes.

Coding Tips

  • •Use this code only when documentation explicitly confirms bilateral involvement
  • •Consider whether separate codes for each eye might be more appropriate if only one eye is affected
