Billable

Posterior synechiae (iris), 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 lens affecting both eyes, which can restrict iris movement and affect vision in both eyes.

Coding Tips

  • •Ensure documentation explicitly confirms bilateral posterior synechiae
  • •Consider the underlying cause (uveitis, trauma, surgery) as it may guide treatment
