Simple chronic conjunctivitis, unspecified eye

This code signifies a persistent, non-infectious inflammation of the conjunctiva, the membrane lining the eyelid and covering the white part of the eye. It indicates a chronic condition without further specification of the underlying cause or specific type of conjunctivitis.

Use this code when documentation indicates a long-standing, uncomplicated inflammation of the conjunctiva, and the specific etiology (e.g., allergic, toxic) is not identified or documented. This code is appropriate when the medical record does not specify which eye is affected.

• Avoid using this code if the documentation specifies a laterality (right, left, or bilateral); instead, use the more specific codes for simple chronic conjunctivitis with laterality.
• Do not use this code if the cause of the chronic conjunctivitis is known (e.g., allergic, contact lens related); instead, code the specific type.
• Ensure the documentation clearly states "chronic" and "simple" or "unspecified" to support the use of this code.
