Summary & Overview
CPT 11044: Surgical Debridement Involving Bone, ≤20 cm2
CPT code 11044 designates surgical debridement involving bone and associated soft tissues for the first or only area measuring 20 cm2 or less. It captures procedures where necrotic or infected bone is removed, often as part of treatment for deep infections, traumatic wounds, or chronic non-healing ulcers. Nationally, accurate coding for this service affects clinical documentation, procedure tracking, and payment for complex wound care and orthopedic procedures.
Key payers analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage considerations, common clinical indications, and related procedure coding to help readers understand how this CPT code is used across settings. It also situates 11044 within the spectrum of debridement codes and highlights typical sites of service such as hospitals, ambulatory surgical centers, and emergency departments.
Readers will find benchmarks and policy context relevant to billing and claims processing, a concise clinical description of the service, and comparisons to adjacent debridement codes to clarify when 11044 is appropriate. The piece provides practical clarity on coding boundaries for bone-involved debridement without offering clinical recommendations.

Clinical & Coding Specifications
Clinical Context
A 64-year-old male with peripheral arterial disease and poorly controlled diabetes presents to the emergency department with a 3-week history of increasing pain, malodor, and purulent drainage from a chronic ulcer of the right lower leg. Examination shows an open wound with exposed necrotic bone at the tibial crest and surrounding cellulitis. Imaging confirms cortical osteomyelitis. The orthopedic surgeon performs operative surgical debridement in an operating room under regional or general anesthesia, removing devitalized epidermis, dermis, subcutaneous tissue, muscle or fascia as needed, and sequestrectomy of necrotic bone. The documented operative note describes removal of necrotic bone and soft tissue totaling 18 cm2, irrigation, and placement of wound packing/negative pressure dressing. Postoperative workflow includes postoperative recovery unit monitoring, IV antibiotics guided by culture results, wound care instructions, and outpatient wound clinic follow-up for dressing changes and possible staged closure or grafting.
