Disc Repositioning & Stabilization - CDT Code Guide
Overview
CDT code D7874 refers to the procedure of repositioning and stabilizing the disc within the temporomandibular joint (TMJ) using arthroscopic techniques. This minimally invasive procedure is typically performed by oral and maxillofacial surgeons to address TMJ dysfunctions that involve disc displacement. The procedure aims to alleviate pain, improve jaw function, and prevent further joint damage. It is commonly indicated in cases where conservative treatments have failed, and there is a clear diagnosis of disc displacement with reduction or without reduction, causing significant functional impairment or pain.
When to Use This Code
- Patients with TMJ disc displacement with reduction causing significant pain
- Cases where conservative treatments for TMJ disorders have failed
- Patients experiencing functional impairment due to TMJ disc displacement
- When imaging confirms disc displacement contributing to TMJ dysfunction
- As part of a comprehensive treatment plan for TMJ disorders
Documentation Requirements
- Detailed patient history and clinical findings supporting TMJ dysfunction
- Radiographic or MRI evidence of disc displacement
- Documentation of previous conservative treatments and their outcomes
- Surgical report detailing the arthroscopic procedure performed
- Post-operative care instructions and follow-up plan
Billing Considerations
When billing for D7874, ensure that the procedure is medically necessary and well-documented. Check with the patient's insurance for coverage specifics, as TMJ procedures can vary in coverage. Common modifiers may include those indicating bilateral procedures or distinct procedural services. Frequency limitations may apply, so verify with the payer.
