What are Cellulitis ICD-10-CM Codes?
Cellulitis is a bacterial skin infection affecting subcutaneous tissue and soft tissues, often resulting in swollen lymph nodes, pain, and skin discoloration. For accurate billing and documentation, practitioners should refer to the appropriate cellulitis ICD-10 codes. These codes also apply when cellulitis occurs alongside acute lymphangitis or acute lymphadenitis across various affected areas.

- Febrile neutrophilic dermatosis (Sweet's syndrome) – especially in differential diagnosis
- Cutaneous abscess that may progress to cellulitis
- Local infection leading to acute lymphangitis or trunk acute lymphadenitis
- Buttock cellulitis, common in sedentary or immobile patients
- Involvement of right axilla, left hand, left foot, or parts of limb
