1. What is CPT Code 70320?

CPT 70320 is used to report a radiologic examination of the teeth, specifically a complete and full mouth examination. This procedure allows dentists to identify abnormalities in the teeth and surrounding tissues, including dental cavities, tooth decay, and potential problems with the jaw and skull. It is an essential diagnostic tool that helps dentists assess the overall oral health of their patients.

2. Official Description

The official description of CPT code 70320 is a radiologic examination of the teeth, providing a complete and full mouth assessment. This code encompasses both intraoral and extraoral X-rays, allowing dentists to evaluate the teeth, tooth roots, bone structure, and developing teeth.

3. Procedure

1. The dentist performs a full mouth radiograph (X-ray) to capture images of the teeth and surrounding tissues.
2. Intraoral X-rays are taken with the X-ray film placed inside the patient’s mouth. These X-rays help identify cavities, assess the health of tooth roots and bone structure, and monitor the development of teeth.
3. Extraoral X-rays focus on the jaw and skull, providing a broader view of the oral and facial structures. These X-rays are particularly useful for identifying impacted teeth and potential issues between the teeth and jaws.
4. The X-ray images are developed, and the dentist analyzes them to identify any abnormalities or areas of concern.
5. The dentist interprets the X-ray findings and uses them to make informed decisions regarding the patient’s oral health and treatment plan.

4. Qualifying circumstances

CPT 70320 is typically performed when there is a need to assess the overall oral health of a patient. It is commonly used for routine dental check-ups, as well as when specific dental conditions or concerns are present. Dentists may order a complete radiologic examination of the teeth when they suspect tooth decay, cavities, impacted teeth, or other abnormalities in the teeth or jaw bones.

5. When to use CPT code 70320

CPT code 70320 should be used when a dentist performs a complete radiologic examination of the teeth, capturing images of the entire mouth.
