CPT® Code 70320

The CPT® Code 70320 refers to a comprehensive radiologic examination of the teeth, specifically a complete full mouth series. This procedure involves the use of various types of dental x-rays to obtain a thorough assessment of the dental structures. The examination typically includes bitewing x-rays, which capture a single view of the upper and lower back teeth, allowing the clinician to evaluate how these teeth align, detect any decay present between them, and assess any bone loss associated with gum disease or infections. Additionally, periapical x-rays are integral to this full mouth series, as they provide detailed images of the entire tooth, from the visible crown down to the root and the surrounding bone structures. These x-rays are crucial for identifying issues that may not be visible above the gum line, such as crowded or impacted teeth, broken roots, abscesses, or other pathological changes. Furthermore, occlusal x-rays are utilized to visualize the roof and floor of the mouth, revealing teeth that have not yet erupted, extra teeth, cleft palates, jaw fractures, foreign objects, and any cysts or abscesses that may be present. It is important to note that for a single view of the teeth, the appropriate code is 70300, while a partial examination that covers less than the full mouth is coded as 70310. The full mouth series, as indicated by code 70320, provides a comprehensive overview necessary for effective diagnosis and treatment planning in dental care.
