Cellulitis of buttock

This code signifies an acute bacterial infection of the skin and subcutaneous tissue specifically affecting the buttock region. It is characterized by localized inflammation, redness, warmth, swelling, and pain, often without clear demarcation. The infection can spread rapidly if not treated.

Apply this code when documentation clearly indicates a diagnosis of cellulitis localized to the buttock. Supporting clinical notes should describe the characteristic signs and symptoms of cellulitis and specify the anatomical site. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure the documentation explicitly states "buttock" as the affected site; avoid using for generalized or unspecified cellulitis.
• Do not confuse with abscess of the buttock (L02.317), which involves a localized collection of pus requiring different management.
• Code any associated systemic infection (e.g., sepsis) or underlying conditions (e.g., diabetes) as additional diagnoses.
