Goniosynechiae, left eye

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 of the left eye, which can affect fluid drainage and eye pressure.

Coding Tips

  • •Verify laterality is documented as left eye in the medical record before assigning this code
  • •Distinguish from posterior synechiae (H21.54x) which involves iris-to-lens adhesions rather than angle adhesions
