Osteotomy
Dental RCM Glossary
A surgical procedure involving deliberate cutting or removal of bone, commonly performed during implant placement, jaw surgery, or impacted tooth removal.
Osteotomy in dentistry refers to the controlled surgical cutting of bone for a variety of clinical purposes. In implant dentistry, an osteotomy describes the preparation of the implant site within the jawbone using sequential drills to create a precisely sized channel for implant placement. In oral and maxillofacial surgery, osteotomy includes more extensive procedures such as sagittal split osteotomy, Le Fort osteotomy, or segmental osteotomy performed to reposition the jaws and correct skeletal discrepancies. The term is also used in the context of removing bone to access impacted teeth, particularly impacted third molars that are partially or fully encased in bone.
The billing complexity of osteotomy procedures stems from the wide range of clinical contexts in which they are performed. When an osteotomy is part of implant site preparation, it is generally considered included in the implant placement fee and is not billed separately. However, when bone cutting is performed as a distinct surgical procedure, such as removing a bony impaction or performing orthognathic surgery, it carries its own specific codes. Orthognathic surgery osteotomies are typically billed to medical insurance using CPT codes rather than CDT codes, and the practice must submit claims with appropriate medical diagnosis codes documenting the functional impairment that necessitates surgical correction.
Practices performing osteotomy procedures should establish clear billing protocols that account for the different coding systems and payer requirements involved. Implant-related osteotomies require documentation of the implant site dimensions, bone density assessment, and surgical technique. Orthognathic osteotomies require a detailed package that often includes cephalometric analysis, dental models, surgical treatment plan, and documentation of functional problems such as difficulty chewing, breathing, or speaking. Predetermination or prior authorization is strongly advised for major osteotomy procedures, as denial rates for orthognathic surgery remain high due to payers disputing the functional necessity of the correction.
Why It Matters for Dental Practices
Osteotomy procedures span multiple dental specialties and billing categories, so correct code selection based on the specific purpose and anatomical site of the bone cut is critical for clean claims and appropriate reimbursement.
Example
An oral surgeon performs a sagittal split osteotomy to correct a patient's mandibular prognathism. Because the procedure addresses a skeletal jaw discrepancy, the practice coordinates benefits between the patient's medical and dental insurance, submitting the primary claim to the medical carrier with appropriate ICD-10 diagnosis codes and the orthognathic surgery CPT code.
