Episcleritis periodica fugax, bilateral

This code describes a recurrent, self-limiting inflammation of the episclera, the thin layer of tissue between the conjunctiva and the sclera, affecting both eyes. It is characterized by sudden onset of redness, irritation, and sometimes mild pain, which typically resolves spontaneously within a few days.

Use this code when documentation clearly indicates a diagnosis of episcleritis that is periodic (recurrent) and transient (fugax), affecting both eyes. Supporting documentation should specify the bilateral involvement and the episodic nature of the condition.

• Ensure the medical record explicitly states "bilateral" involvement; otherwise, consider laterality-specific codes.
• Differentiate from scleritis (H15.0-), which involves deeper inflammation and is typically more severe.
• Do not use for a single, isolated episode of episcleritis without evidence of recurrence.
