D7490

Radical Resection of Maxilla or Mandible - CDT Code Guide

Oral & Maxillofacial Surgery/Excision of Bone Tissue

Overview

CDT code D7490 refers to the radical resection of the maxilla or mandible, a complex oral and maxillofacial surgery procedure. This involves the partial resection of the jawbone, either the maxilla or mandible, to remove a lesion along with a margin of normal-appearing bone. This procedure is typically performed to address malignant or aggressive benign tumors, cysts, or other pathological conditions affecting the jaw. Reconstruction and bone grafting, which may be necessary following the resection, are billed separately. Dental professionals should be aware of the clinical indications and the comprehensive nature of this surgery, which often requires a multidisciplinary approach.

When to Use This Code

  • Removal of malignant tumors in the maxilla or mandible
  • Excision of aggressive benign tumors or cysts in the jaw
  • Surgical intervention for osteomyelitis with bone involvement
  • Management of severe trauma resulting in bone lesions
  • Cases requiring removal of bone to achieve clear margins

Documentation Requirements

  • Detailed surgical report including the extent of resection
  • Pre-operative imaging studies (e.g., CT, MRI) showing the lesion
  • Pathology report confirming the nature of the lesion
  • Post-operative notes detailing reconstruction plans
  • Patient consent forms and discussion of potential risks
  • Documentation of multidisciplinary team involvement, if applicable

Billing Considerations

When billing for D7490, it's important to note that reconstruction and bone grafting are billed separately. Ensure that all related procedures are documented clearly to avoid denials. Common modifiers such as -22 for increased procedural services may be applicable if the surgery is more complex than usual. Check with the patient's insurance for any pre-authorization requirements and coverage limitations.
