Abscess of right upper eyelid

This diagnosis code identifies a localized collection of pus within the tissue of the upper eyelid on the right side. It signifies an inflammatory response, typically due to bacterial infection, leading to swelling, pain, and redness in the affected area.

Apply this code for patients presenting with a confirmed abscess specifically located in the right upper eyelid. Documentation should clearly indicate the presence of an abscess and specify its location to the right upper eyelid, often noted by physical examination findings such as a tender, fluctuant mass.

• Differentiate from other eyelid inflammations like chalazion or hordeolum, which have distinct codes.
• Ensure laterality is accurately documented and coded; this code is specific to the right upper eyelid.
• If the abscess is due to an external hordeolum, consider using the more specific code for external hordeolum of the right upper eyelid.
