Surgical Sialolithotomy - CDT Code Guide

Oral & Maxillofacial Surgery/Other Repair Procedures

Overview

CDT code D7979 refers to the surgical sialolithotomy procedure, which involves the removal of a sialolith, or salivary stone, from the gland or ductal portion of the gland without making a surgical incision. This procedure is typically performed through non-surgical methods such as manual manipulation, ductal dilation, or other techniques that avoid cutting into the gland or duct. It is often used in cases where a patient experiences blockage or discomfort due to a sialolith, which can impede saliva flow and cause swelling or pain. Dental professionals may encounter this scenario in patients presenting with symptoms of salivary gland obstruction, and it is crucial to address these issues promptly to prevent further complications.

When to Use This Code

When a patient presents with symptoms of salivary gland obstruction due to a sialolith.
In cases where non-invasive methods can effectively remove the sialolith without incision.
When imaging confirms the presence of a sialolith that can be accessed through non-surgical means.
For patients experiencing recurrent salivary gland infections linked to sialoliths.
When a patient reports pain or swelling in the salivary gland area that is traced to a sialolith.

Documentation Requirements

Detailed patient history indicating symptoms of salivary gland obstruction.
Imaging results confirming the presence and location of the sialolith.
Description of the non-surgical method used for sialolith removal.
Clinical notes on the patient's response to the procedure.
Post-procedure care instructions provided to the patient.
Documentation of any complications or follow-up appointments scheduled.

Billing Considerations

When billing for D7979, it is important to ensure that the procedure is documented as non-incisional. Frequency limitations may apply, and it's crucial to verify with the patient's insurance provider regarding coverage for non-surgical sialolith removal. Common modifiers may include those indicating a bilateral procedure if applicable. Always check for any pre-authorization requirements.
