H21.503

Billable

Unspecified adhesions of iris, bilateral

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

What This Code Means

Abnormal scar tissue or adhesions connecting the iris (colored part of the eye) to surrounding structures in both eyes. This can restrict eye movement and affect vision.

Coding Tips

  • •Confirm documentation clearly indicates bilateral involvement
  • •If the specific type of adhesion is documented, use the more specific codes H21.51x or H21.52x for better specificity
