Simple chronic conjunctivitis, bilateral

This code signifies a persistent, non-infectious inflammation of the conjunctiva affecting both eyes. It is characterized by chronic irritation, redness, and discharge, without the acute purulence or severe symptoms associated with infectious conjunctivitis. The condition is typically long-standing, often lasting for weeks or months.

Apply this code when documentation indicates a diagnosis of chronic conjunctivitis affecting both eyes, without further specification of the underlying cause or a more specific type. This is appropriate when the physician explicitly states "simple chronic conjunctivitis, bilateral" or similar phrasing indicating a non-acute, non-specific, and chronic inflammation of the conjunctiva in both eyes.

• Ensure the documentation clearly specifies "chronic" and "bilateral" to support this code.
• Differentiate from acute conjunctivitis (H10.0-H10.3) and other specified types of chronic conjunctivitis (e.g., allergic H10.43-).
• If a specific cause for the chronic conjunctivitis is identified (e.g., allergic, toxic), a more specific code should be used instead.
