D7873

Arthroscopy - Lavage & Lysis - CDT Code Guide

Oral & Maxillofacial Surgery/Reduction of Dislocation and Management of Other Temporomandibular Joint Dysfunctions

Overview

CDT Code D7873 refers to the arthroscopic procedure involving lavage and lysis of adhesions within the temporomandibular joint (TMJ). This minimally invasive surgery is performed using an arthroscope, a specialized instrument that allows the dentist or oral surgeon to visualize the joint space and remove adhesions that may be causing pain or restricted movement. Lavage, or the washing out of the joint cavity, helps to clear debris and inflammatory mediators, potentially alleviating symptoms associated with TMJ disorders. This procedure is typically considered when conservative treatments have failed, and the patient continues to experience significant discomfort or functional impairment.

When to Use This Code

Patients with TMJ dysfunction unresponsive to non-surgical treatments
Cases where imaging shows adhesions within the TMJ
Patients experiencing restricted jaw movement due to joint adhesions
When lavage is needed to reduce inflammation in the TMJ
To improve joint function and reduce pain in chronic TMJ cases

Documentation Requirements

Detailed patient history and examination notes
Pre-operative imaging reports confirming the presence of adhesions
Surgical notes detailing the procedure performed
Post-operative care instructions and follow-up plans
Patient consent forms specific to arthroscopic procedures
Documentation of prior treatments and their outcomes

Billing Considerations

Ensure accurate documentation of the procedure and medical necessity. Be aware of payer-specific guidelines regarding TMJ treatments, as coverage can vary. Common modifiers may include those indicating bilateral procedures if both joints are treated. Frequency limitations might apply, so verify with the patient's insurance provider.
