This diagnostic procedure is crucial in identifying active infections, allowing dental professionals to take necessary precautions to prevent the spread of infectious diseases within dental practices. Typically, this test involves collecting a sample from the patient, often a nasal or throat swab, and analyzing it for specific antigens related to the pathogen in question. Dental practices may use this test when there is a need to confirm the presence of a pathogen to ensure the safety of both staff and patients. In the context of the ongoing COVID-19 pandemic, this code is particularly relevant for testing for the coronavirus.

Prior to performing aerosol-generating procedures on a patient with unknown COVID-19 status.
In response to a known exposure to a public health-related pathogen within the dental office.
As part of routine screening protocols in high-risk areas or populations.
To comply with public health guidelines during an outbreak of a specific pathogen.

Documentation Requirements

Patient's consent for testing.
Detailed clinical notes justifying the need for the test.
