Genetic Sample Collection - CDT Code Guide
Overview
CDT code D0422 refers to the collection and preparation of genetic sample material for laboratory analysis and report. This procedure is crucial in diagnostic settings where genetic information is needed to understand a patient's health condition better. Dental professionals use this code when they collect samples such as saliva or tissue that require genetic analysis to assist in diagnosing conditions that may have a genetic component.
Typically, this procedure is part of a comprehensive diagnostic workup, especially in cases where genetic factors might influence dental health, such as predispositions to certain oral diseases or conditions. The process involves careful collection, labeling, and preparation of the sample to ensure it is suitable for laboratory analysis, followed by a detailed report that aids in clinical decision-making.
When to Use This Code
- When a patient has a family history of genetic oral health issues.
- In cases where genetic predisposition to periodontal disease is suspected.
- When evaluating a patient for genetic markers related to oral cancer.
- As part of a comprehensive diagnostic evaluation for complex cases.
- When a patient presents with unexplained oral health symptoms that may have a genetic basis.
Documentation Requirements
- Detailed patient history indicating the need for genetic analysis.
- Consent form signed by the patient for genetic testing.
- Accurate labeling of the collected sample with patient information.
- Documentation of the method of collection and any special handling instructions.

Billing Considerations
When billing for D0422, ensure that the procedure is justified by the patient's clinical condition and documented need for genetic analysis. Be aware of any frequency limitations imposed by insurance providers, as genetic testing may not be covered for all patients. Common modifiers may include those indicating the specific nature of the sample or special handling requirements. Verify with the patient's insurance for coverage specifics, as genetic testing can often require pre-authorization.
