Cutaneous abscess of flank

This code signifies a localized collection of pus within the skin and subcutaneous tissue specifically located on the flank region of the body. It indicates an inflammatory response, typically due to bacterial infection, resulting in a tender, swollen, and often erythematous lesion.

Apply this code when documentation clearly identifies a cutaneous abscess situated on the patient's flank. Supporting documentation should include physical exam findings describing the lesion's characteristics and its precise anatomical location. This code is appropriate for both initial encounters and subsequent visits related to the management of the abscess.

• Differentiate from cellulitis without abscess formation; an abscess requires a distinct purulent collection.
• Ensure the documentation specifies "flank" as the anatomical site, not a generalized trunk or abdomen location.
• Consider an additional code for the causative organism (e.g., Staphylococcus aureus) if identified and documented.
