Unspecified adhesions of iris, left eye

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

What This Code Means

The iris (the colored part of the eye) in the left eye has abnormal scar tissue or connections that are causing it to stick to other parts of the eye, but the specific type or cause of these adhesions has not been documented. This condition can affect vision and eye movement.

Coding Tips

  • •Verify whether the adhesions are anterior synechiae (iris stuck to cornea) or posterior synechiae (iris stuck to lens) - if documented, use more specific codes H21.50- instead of the unspecified code
  • •Ensure laterality is correctly identified as left eye (H21.502); confirm documentation doesn't specify right eye (H21.501) or bilateral (H21.503)
