Abscess of left lower eyelid

This code signifies a localized collection of pus within the tissues of the lower eyelid on the patient's left side. It indicates an inflammatory process, typically bacterial, leading to swelling, redness, and tenderness in the affected area.

Apply this code when documentation clearly states an abscess is present in the left lower eyelid. This diagnosis is supported by physical exam findings such as a palpable, fluctuant mass, erythema, and pain localized to the specified eyelid.

• Ensure laterality (left) and specific eyelid (lower) are explicitly documented.
• Distinguish from cellulitis (H00.01x, H00.02x), which is a more diffuse infection without a localized pus collection.
• Do not use for styes (hordeolum) unless specifically diagnosed as an abscess.
