H20.021

Billable

Recurrent acute iridocyclitis, right eye

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

What This Code Means

This code describes inflammation of the iris and ciliary body (the structures inside the eye that control focus and produce fluid) that keeps coming back in the right eye. The patient experiences repeated episodes of acute (sudden) eye inflammation rather than a continuous chronic condition.

Coding Tips

  • Verify laterality is documented as right eye only; if bilateral or left eye, use different codes (H20.022 for left, H20.023 for bilateral)
  • Confirm the inflammation is recurrent (multiple episodes) and acute in nature; if it's chronic or first occurrence, use different H20 codes such as H20.001 (acute iridocyclitis, right eye) or H20.031 (chronic iridocyclitis, right eye)
