Carbuncle of left axilla

This code describes a severe, deep-seated bacterial infection of the hair follicles and surrounding subcutaneous tissue in the left armpit. It presents as a cluster of interconnected boils, often with multiple draining sinuses, and is typically caused by Staphylococcus aureus. Patients commonly experience pain, fever, and malaise.

Assign this code when documentation clearly identifies a carbuncle located specifically in the left axilla. Supporting documentation should include a physician's diagnosis of carbuncle and a clear indication of the anatomical site. This code is appropriate for both initial encounters and subsequent care related to this specific infection.

• Ensure the documentation specifies "carbuncle" and not just a "furuncle" or "abscess," as these have different codes.
• Verify the laterality is explicitly stated as "left axilla" to avoid miscoding to an unspecified or right-sided lesion.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
