Primary iridocyclitis, unspecified eye

This code signifies inflammation of the iris and ciliary body, originating without an identifiable underlying systemic disease or external cause. It represents the initial or main presentation of this inflammatory process within the eye.

Apply this code when documentation indicates primary iridocyclitis without specifying laterality (right, left, or bilateral). This is appropriate when the physician's diagnosis explicitly states "primary iridocyclitis" and does not provide further details regarding the affected eye.

• Only use this code when laterality is truly unspecified in the medical record.
• Avoid using this code if documentation specifies "right eye," "left eye," or "bilateral" iridocyclitis; instead, select the more specific code.
• Ensure the physician's documentation clearly supports the "primary" nature of the iridocyclitis, ruling out secondary causes.
