Photokeratitis, bilateral

This code describes an inflammatory condition of the cornea caused by exposure to intense ultraviolet (UV) radiation, affecting both eyes. It results in superficial corneal damage, often presenting with pain, photophobia, and foreign body sensation. This condition is typically acute and resolves within 24-48 hours.

Apply this code when documentation clearly indicates a diagnosis of photokeratitis affecting both the right and left eyes. Common scenarios include exposure to welding arcs without proper eye protection, prolonged sun exposure on reflective surfaces like snow or water, or tanning bed use. The physician's notes should specify the bilateral involvement.

• Ensure the documentation explicitly states "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Do not confuse with other forms of keratitis (e.g., bacterial, viral) unless UV exposure is the confirmed etiology.
• Consider an external cause code (V00-Y99) if the source of UV exposure (e.g., welding, sun) is documented and relevant for reporting.
