Recurrent acute iridocyclitis, unspecified eye

This code signifies repeated episodes of acute inflammation affecting the iris and ciliary body of the eye, without specifying which eye is affected. It indicates a relapsing form of anterior uveitis characterized by sudden onset and resolution.

Apply this code when documentation clearly states "recurrent acute iridocyclitis" but does not specify laterality (e.g., right, left, or bilateral). This is appropriate when the physician's notes confirm multiple distinct acute inflammatory events of the iris and ciliary body.

• Avoid using this code if laterality is documented; instead, choose the more specific codes for right (H20.021), left (H20.022), or bilateral (H20.023) recurrent acute iridocyclitis.
• Ensure the documentation specifies "recurrent" or "repeated episodes" to differentiate from a single acute episode (H20.01-).
• Do not use for chronic iridocyclitis (H20.1-).
