Summary & Overview
CPT 21247: Mandibular Condyle Reconstruction Using Autologous Graft
CPT code 21247 covers surgical reconstruction of the mandibular condyle using the patient’s own graft material to correct congenital facial deformity or jaw dysfunction. This procedure is clinically significant because it addresses functional impairment of the temporomandibular joint region and facial asymmetry, with implications for airway, mastication, speech, and long-term craniofacial development. Nationally, coverage policies and reimbursement for complex maxillofacial reconstructions influence access to multidisciplinary surgical care and coordination with dental, orthodontic, and plastic surgery services.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and common service settings, plus payer-aligned benchmarks and policy considerations relevant to coverage and coding for maxillofacial reconstruction. The publication outlines where CPT code 21247 typically applies, common modifiers encountered in claims, and how this code fits within surgical and reconstructive service lines. It also highlights areas where payers may apply medical necessity criteria or prior authorization for complex autograft reconstructions. The document is intended to inform coding, billing, and administrative stakeholders about the clinical purpose of the code and the payer landscape affecting utilization and reimbursement.
Billing Code Overview
CPT code 21247 describes surgical reconstruction of the mandibular condyle using autologous graft material (tissue taken from the patient). The procedure addresses congenital facial deformities or jaw dysfunctions—conditions such as hemifacial microsomia—that affect the rounded bony projection where the lower jaw articulates with the skull.
Service type: Reconstructive maxillofacial surgery using autograft
Typical site of service: Inpatient hospital or ambulatory surgical center (operating room)

Clinical & Coding Specifications
Clinical Context
A pediatric patient born with unilateral hemifacial microsomia presents with mandibular condylar hypoplasia causing facial asymmetry, malocclusion, and limited mandibular function. The patient has failed conservative management and orthodontic interventions; imaging (panorex, CT) confirms underdeveloped mandibular condyle on the affected side. A maxillofacial surgeon plans an autogenous costochondral graft reconstruction of the mandibular condyle to restore ramus height, temporomandibular joint contour, and improve occlusion and facial symmetry. Preoperative workflow includes multidisciplinary evaluation (oral and maxillofacial surgery, pediatric plastic surgery, orthodontics), informed consent, pre-op imaging and dental models, anesthesia assessment, and donor-site planning. Intraoperative steps include general endotracheal anesthesia, harvest of autogenous graft (commonly rib), shaping and fixation of the graft to reconstruct the condylar head and glenoid fossa interface, possible interpositional materials, and intraoperative occlusal checks. Postoperative workflow includes admission for pain control and airway monitoring, early jaw physiotherapy, follow-up imaging, coordination with orthodontics for occlusal adjustments, and long-term surveillance for growth and graft remodeling.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
62 | Two surgeons | Use when two surgeons work together as primary surgeons during a complex reconstruction requiring separate skills (eg, oral maxillofacial and pediatric plastic surgeon). |
63 | Procedure performed on infants less than 4 kg | Use when applicable for neonatal patients meeting weight criteria (rare). |
66 | Surgical team technique | Use when a coordinated surgical team approach is reported per payer rules. |
78 | Unplanned return to OR for related procedure during global period | Use if the patient requires an immediate return to the OR for a complication related to the reconstruction. |
79 | (Not in supplied list) | Data not available in the input. |
52 | Reduced services | Use when parts of the planned reconstruction are not completed and services are reduced. |
53 | Discontinued procedure | Use if the procedure is started but then aborted for patient safety reasons. |
26 | Professional component | Use if billing only the professional component of an included service that has a technical component (rare for this code). |
51 | Multiple procedures | Use when multiple distinct procedures are performed the same operative day in addition to the reconstruction. |
22 | Increased procedural services | Use when operative work is substantially greater than usual and documentation supports the increased complexity. |
80 | Assistant surgeon | Use when a physician assistant or assistant surgeon provides assistant-at-surgery services (surgeon assistant). |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use when a qualified nonphysician practitioner performs part of the service where allowed. |
RT | Right side | Use to identify procedure on the right mandible/condyle when laterality reporting is required. |
LT | Left side | Use to identify procedure on the left mandible/condyle when laterality reporting is required. |

| 2080P0222X | Plastic Surgery | Pediatric craniofacial reconstructions often involve plastic surgeons for soft-tissue and contouring. |
| 207L00000X | Otolaryngology | Otolaryngologists with facial plastic training may participate in TMJ/craniofacial procedures. |
| 208000000X | General Surgery | May be consulted for complex donor-site harvest considerations (eg, rib harvest) in some centers. |
| 206Q00000X | Dentistry | Oral surgery and dental specialists involved in pre- and postoperative occlusal management. |
