CPT® Code 70310

The CPT® Code 70310 refers to a radiologic examination of the teeth, specifically a partial examination that encompasses less than a full mouth. This procedure involves the use of various types of dental x-rays to assess the condition of the teeth and surrounding structures. A common type of x-ray utilized in this examination is the bitewing x-ray, which provides a single view of the upper and lower back teeth. This view is crucial for evaluating how these teeth come together, identifying any decay that may exist between them, and detecting any bone loss associated with gum disease or infection. Additionally, periapical x-rays are often employed to visualize the entire tooth, from the crown down to the root, along with the supporting bone structures. These x-rays are particularly useful for examining conditions that occur below the gum line, such as crowded or impacted teeth, broken tooth roots, abscesses, or other pathological changes. Occlusal x-rays are also part of this examination, as they capture the roof and floor of the mouth, revealing teeth that have not yet erupted through the gums, extra teeth, cleft palates, jaw fractures, foreign objects, and cysts or abscesses. It is important to note that for a single view of the teeth, the appropriate code is 70300, while 70310 is designated for a partial examination covering less than the full mouth, and 70320 is used for a complete series of x-rays of the mouth.
