Secondary infectious iridocyclitis, right eye

This code signifies inflammation of the iris and ciliary body (iridocyclitis) in the right eye, where the inflammation is a consequence of an underlying infectious process. It indicates that the infection is not primary to the uveal tract but rather has spread from another site or is a systemic infection manifesting in the eye.

Use this code when documentation specifies iridocyclitis in the right eye caused by an identifiable infectious agent, such as bacteria, viruses, fungi, or parasites. This applies to cases where the infection is secondary to conditions like herpes zoster ophthalmicus, syphilis, tuberculosis, or Lyme disease affecting the eye.

• Always code the underlying infectious disease first, followed by this code to show the manifestation.
• Ensure the documentation clearly specifies "secondary" and identifies the right eye.
• Distinguish from non-infectious iridocyclitis (H20.1-) and primary infectious iridocyclitis (H20.01-).
