Unspecified acute conjunctivitis, unspecified eye

This code signifies an acute inflammation of the conjunctiva, the membrane lining the eyelid and covering the white part of the eye, where the specific cause (e.g., bacterial, viral, allergic) is not documented. It also indicates that the affected eye (right, left, or bilateral) is not specified in the medical record.

Use this code when the provider's documentation clearly states "acute conjunctivitis" but does not specify the etiology or laterality. This is appropriate for initial encounters where the cause is undetermined or when the documentation lacks sufficient detail for a more specific diagnosis.

• Avoid using this code if the documentation specifies the type of conjunctivitis (e.g., viral, bacterial) or the affected eye(s).
• Query the provider for clarification on etiology and laterality to allow for more specific coding whenever possible.
• This code represents a less specific diagnosis; strive for higher specificity if supported by the clinical documentation.
