Cellulitis of right lower limb

This code signifies a bacterial infection of the skin and subcutaneous tissue affecting the right lower extremity. It presents as a spreading area of redness, warmth, swelling, and tenderness, often accompanied by fever and malaise. The infection typically does not involve the underlying fascia or muscle.

Apply this code when documentation clearly indicates cellulitis localized to the right lower limb, such as the thigh, leg, ankle, or foot. Supporting documentation should include physical exam findings consistent with cellulitis and the specific laterality. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure documentation specifies "right" lower limb; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from erysipelas, which is a more superficial infection with sharply demarcated borders.
• Code any associated complications, such as lymphangitis or abscess, separately and sequence appropriately.
