H21.509
BillableUnspecified adhesions of iris and ciliary body, unspecified eye
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes scar tissue or abnormal connections that have formed between the iris (the colored part of the eye) and the ciliary body (muscles that control the lens), but the specific type of adhesion is not documented and the affected eye is not specified. This condition can develop after eye inflammation, injury, or surgery.
Coding Tips
- •If the eye is specified (right, left, or bilateral), use a more specific code (H21.501, H21.502, or H21.503) rather than the unspecified code H21.509
- •Review clinical documentation to determine if the adhesion type is specified (such as posterior synechiae or anterior synechiae), as this may allow for a more precise code selection
