Partial Ostectomy - CDT Code Guide

Oral & Maxillofacial Surgery/Surgical Incision

Overview

CDT Code D7550 refers to the partial ostectomy or sequestrectomy procedure, which involves the removal of non-vital bone. This procedure is typically necessary when a patient has loose or sloughed-off dead bone due to infection or compromised blood supply. Commonly performed by oral and maxillofacial surgeons, this surgical intervention helps prevent further complications and promotes healing. Patients who have experienced trauma, severe periodontal disease, or osteomyelitis may require this procedure. The goal is to remove the necrotic bone tissue to allow healthy bone and tissue to regenerate.

When to Use This Code

When a patient presents with necrotic bone due to osteomyelitis.
In cases of severe periodontal disease leading to bone death.
Following trauma that results in compromised blood supply to the bone.
When there is a need to remove bone fragments that have sloughed off due to infection.
In preparation for further reconstructive surgery where dead bone is present.

Documentation Requirements

Detailed patient history indicating the presence of non-vital bone.
Radiographic evidence supporting the diagnosis of necrotic bone.
Clinical notes describing the extent and location of the bone to be removed.
Surgical report detailing the procedure performed and any complications encountered.
Post-operative care instructions and follow-up plan.
Consent forms signed by the patient acknowledging understanding of the procedure.

Billing Considerations

When billing for D7550, ensure documentation supports the medical necessity of the procedure. Check for frequency limitations based on the patient's insurance plan. Common modifiers like -22 for increased procedural services may be applicable if the surgery is more complex than usual. Verify with the patient's insurance for coverage specifics, as some plans may require prior authorization.
