Summary & Overview
CPT 21440: Closed Treatment of Alveolar Ridge Fracture, Manipulation
CPT code 21440 describes closed treatment of fractures of the mandibular and maxillary alveolar ridge using manipulation without an incision. This code captures urgent and elective repair of blunt-force trauma to the tooth-bearing ridge and is relevant to oral and maxillofacial surgeons, emergency departments, and ambulatory surgical providers. Nationally, proper use of this code affects surgical coding accuracy, payer medical necessity reviews, and facility billing for outpatient and inpatient procedural care.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage considerations and common modifiers in claims workflows.
Readers will learn the clinical and billing context for using CPT code 21440, typical sites of service, and common documentation elements that support closed manipulation for alveolar ridge fractures. The report summarizes benchmarks and policy implications relevant to procedural coding, explains how this code fits within head and neck trauma care pathways, and highlights operational considerations for surgical and emergency care settings. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 21440 covers closed treatment of fractures of the mandibular and maxillary alveolar ridge — the thickened bone along the upper and lower jaw that holds tooth sockets — using manipulation without an incision. This procedure addresses damage from blunt force trauma to the alveolar ridge.
-
Service type: Closed manipulation for alveolar ridge fracture repair
-
Typical site of service: Outpatient surgical suite, ambulatory surgery center, or hospital operating room depending on injury severity and patient needs
Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after an altercation with blunt facial trauma to the lower jaw. He reports localized tooth mobility, malocclusion, alveolar ridge pain, and visible bruising of the gingiva. Clinical exam and panoramic radiograph demonstrate a nondisplaced fracture of the mandibular alveolar ridge without open skin laceration or intraoral mucosal wound requiring incision. The oral and maxillofacial surgeon performs closed reduction and manipulation of the alveolar segment under local anesthesia with supplemental conscious sedation to reposition tooth-bearing bone and stabilize occlusion. The procedure is documented as manipulation without incision, operative time, anesthesia type, pre- and post-reduction occlusion assessment, and any temporary splinting applied. Postoperative instructions, analgesia, and a follow-up oral exam are documented. Typical site of service: hospital outpatient department, emergency department, or ambulatory surgery center. Service type: closed reduction of alveolar ridge fracture (manipulation without incision). Typical clinicians: oral and maxillofacial surgeons, general dentists with surgical privileges, and otolaryngologists with facial trauma expertise.
