Cellulitis of right upper limb

This code identifies a bacterial skin infection characterized by inflammation, redness, warmth, and swelling affecting the right arm, forearm, or hand. The infection involves the deeper layers of the dermis and subcutaneous tissue, often presenting with a rapidly spreading erythema.

Apply this code when documentation clearly specifies cellulitis located on any part of the patient's right upper extremity. Supporting documentation should include a physician's diagnosis of cellulitis and the specific anatomical site.

• Ensure laterality is explicitly documented as "right upper limb" to support this specific code.
• Do not use this code for abscesses, lymphangitis, or other localized skin infections; these have distinct codes.
• Consider an additional code for the underlying cause if known (e.g., open wound, insect bite).
