Conjunctival hyperemia, right eye

This code signifies an abnormal redness or engorgement of the blood vessels in the conjunctiva of the right eye. It indicates inflammation or irritation of the ocular surface, often presenting as a "bloodshot" appearance.

Use this code when documentation specifically indicates conjunctival hyperemia affecting the right eye, without further specification of the underlying cause. This is appropriate for conditions like allergic conjunctivitis, viral conjunctivitis, or irritation from foreign bodies, where the primary finding is the redness itself.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• If the underlying cause of the hyperemia is known and more specific, code the definitive diagnosis first, and use this code as a secondary diagnosis if the hyperemia is a significant symptom.
• Do not use this code if a more specific diagnosis for the conjunctival inflammation (e.g., acute serous conjunctivitis) is documented.
