Conjunctival hyperemia, left eye

This code signifies an abnormal redness of the conjunctiva, specifically affecting the left eye. It indicates an increased blood flow to the conjunctival vessels, often a sign of inflammation or irritation.

Apply this code when documentation clearly states "conjunctival hyperemia, left eye" or describes a red, injected left conjunctiva without further specification of an underlying inflammatory condition. This is often used for non-specific redness or when the cause is unknown or not yet diagnosed.

• Ensure laterality is explicitly documented as "left eye" to support this specific code.
• Do not use if a more specific diagnosis for the conjunctival inflammation (e.g., conjunctivitis due to bacteria, allergy) is known and documented.
• Consider if an additional code for the underlying cause of the hyperemia is warranted, if identified.
