Episcleritis periodica fugax, unspecified eye

This code describes a recurrent, self-limiting inflammation of the episclera, the thin layer of tissue between the conjunctiva and the sclera. It is characterized by sudden onset of redness, irritation, and sometimes pain in the eye, which typically resolves spontaneously within a few days. The "fugax" aspect emphasizes its transient and recurrent nature.

Use this code when documentation specifies a diagnosis of episcleritis periodica fugax without laterality specified. This diagnosis is often made clinically based on the characteristic presentation and resolution, and may be supported by a history of similar episodes.

• This code is for unspecified eye; if laterality is documented (right or left), use the more specific codes H15.111 or H15.112.
• Do not confuse with scleritis (H15.0-), which involves deeper inflammation of the sclera and is typically more severe.
• Ensure documentation clearly states "episcleritis periodica fugax" to support this specific diagnosis.
