Zygomatic Implant Placement - CDT Code Guide
Overview
CDT Code D7994 refers to the surgical placement of a zygomatic implant. This procedure involves placing an implant in the zygomatic bone, which exits through the maxillary mucosal tissue. It provides support and attachment for a maxillary dental prosthesis, often used in cases where traditional implants are not feasible due to insufficient bone in the upper jaw. Typically, this procedure is performed by an oral and maxillofacial surgeon and is crucial for patients requiring prosthetic rehabilitation when conventional implants cannot be used. The zygomatic implant offers an alternative solution for patients with severe maxillary bone loss, allowing for effective prosthetic support and improved oral function.
When to Use This Code
- Patients with severe maxillary bone loss where traditional implants are not viable
- Cases requiring immediate loading of a maxillary prosthesis
- Patients who have undergone maxillectomy
- Individuals with congenital defects affecting the maxilla
- Rehabilitation of edentulous maxilla in patients with insufficient bone volume
Documentation Requirements
- Detailed surgical report outlining the procedure
- Pre-operative imaging showing insufficient maxillary bone
- Post-operative imaging confirming implant placement
- Patient consent forms for surgical intervention
- Documentation of prosthetic planning and design
Billing Considerations
When billing for D7994, it's important to note that this code may require prior authorization from insurance providers due to its complexity. Frequency limitations typically do not apply, but documentation supporting medical necessity is crucial. Common modifiers include those indicating bilateral procedures or additional surgical complexity. Ensure coordination with the patient's insurance to verify coverage, as some plans may consider this procedure experimental or not covered.
