Secondary infectious iridocyclitis, bilateral

This code signifies inflammation of both the iris and ciliary body (iridocyclitis) that is a direct consequence of an underlying systemic or localized infection. The infection itself is not originating within the eye but is causing a secondary inflammatory response in the anterior uvea.

Apply this code when documentation clearly indicates bilateral iridocyclitis caused by an identifiable infectious agent elsewhere in the body (e.g., viral, bacterial, fungal, parasitic infections). The medical record should specify the infectious etiology and confirm the bilateral involvement of the iris and ciliary body.

• Always sequence the underlying infectious disease code first, followed by this code for the ocular manifestation.
• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral or unspecified eye code.
• Distinguish from primary infectious iridocyclitis (H20.01-), where the infection originates within the eye itself.
