Conjunctival hyperemia, bilateral

This code signifies bilateral redness or engorgement of the blood vessels in the conjunctiva, the transparent membrane lining the eyelid and covering the white part of the eye. It indicates a non-specific inflammation or irritation affecting both eyes.

Apply this code when documentation explicitly states "conjunctival hyperemia, bilateral" or describes bilateral conjunctival injection without further specification of an underlying cause (e.g., infection, allergy). This is often a finding during a general eye exam or when a patient presents with non-specific eye redness in both eyes.

• Ensure documentation specifies "bilateral" involvement; otherwise, use a laterality-specific code.
• Do not use this code if a more specific diagnosis for the conjunctival hyperemia (e.g., conjunctivitis due to bacteria, allergic conjunctivitis) is documented.
• This code is often a symptom code; sequence it after the definitive diagnosis if one is identified.
