Tomographic Survey - CDT Code Guide
Overview
CDT Code D0322 refers to a tomographic survey, a specialized diagnostic imaging procedure used in dentistry. This procedure involves capturing detailed cross-sectional images of the dental structures, which are particularly useful for assessing complex cases that require a comprehensive view of the oral anatomy. Tomographic surveys are often employed when traditional X-rays do not provide sufficient detail, such as in the evaluation of dental implants, assessment of temporomandibular joint disorders, or planning for orthodontic treatments. By providing a three-dimensional perspective, this imaging technique aids in accurate diagnosis and treatment planning, ensuring optimal patient care.
When to Use This Code
- Evaluating the placement and integration of dental implants
- Assessing temporomandibular joint disorders
- Planning complex orthodontic treatments
- Diagnosing cysts, tumors, or other pathologies in the jaw
- Investigating unexplained dental pain or anomalies
Documentation Requirements
- Detailed patient history and clinical indications for the survey
- Informed consent form signed by the patient
- Interpretation and analysis of the tomographic images
- Documentation of findings in the patient's dental record
- Referral notes if the survey was requested by another dental specialist
Billing Considerations
When billing for a tomographic survey using D0322, it's important to verify the patient's insurance coverage for advanced imaging procedures, as some plans may have specific limitations or require pre-authorization. Frequency limitations may apply, so ensure that the procedure is justified by clinical necessity. Common modifiers may include those indicating the reason for the imaging or the specific area of focus. Always check with the patient's insurance provider for any specific billing guidelines or requirements.
