What is the difference between autogenous and non-autogenous grafts?

Autogenous grafts use the patient's own tissue, requiring a donor site, while non-autogenous grafts use external donor material, eliminating the need for a second surgical site.

Can D4275 be used for multiple teeth?

D4275 is typically billed per site, so if multiple teeth require grafting, each site may need to be documented and billed separately.

What materials are used in non-autogenous grafts?

Non-autogenous grafts may use materials such as allografts, xenografts, or synthetic substitutes, depending on the clinical situation and patient needs.

How long is the recovery period after a connective tissue graft?

Recovery time can vary, but patients generally experience healing over a few weeks, with follow-up visits necessary to monitor progress and ensure successful graft integration.

Connective Tissue Graft - CDT Code Guide

Periodontics/Surgical Services (Including Usual Postoperative Care)

Overview

CDT Code D4275 refers to a non-autogenous connective tissue graft procedure, which is a periodontal surgical service. This procedure involves the use of donor material to perform a graft at a recipient site, typically where there is a need to cover exposed roots or augment soft tissue. Unlike autogenous grafts, this procedure does not require a separate donor site from the patient, as the graft material is sourced externally. This can be particularly beneficial in cases where the patient's own tissue is insufficient or when minimizing surgical sites is desired. The procedure is typically performed under local anesthesia and involves a split thickness incision to prepare the recipient site, ensuring the overlaying flap of gingiva or mucosa is retained.

When to Use This Code

Recession coverage for exposed tooth roots
Augmentation of soft tissue around dental implants
Enhancement of gingival tissue in edentulous areas
Patients with insufficient autogenous tissue for grafting
Minimizing surgical sites for patient comfort

Documentation Requirements

Detailed clinical notes describing the recipient site
Description of the donor material used
Pre-operative and post-operative photographs
Patient consent forms for the use of donor material
Post-operative care instructions provided to the patient
Insurance pre-authorization, if applicable

Billing Considerations

When billing for D4275, ensure that the procedure is documented thoroughly, as insurance companies may require detailed justification for the use of non-autogenous materials. Frequency limitations may apply, and it is crucial to check with the patient's insurance provider for any specific guidelines. Common modifiers such as -22 for increased procedural services may be applicable if the procedure is more complex than usual.
