Code D0418 is for the analysis of a saliva sample.
The purpose of this code is for the chemical or biological analysis of a saliva sample for diagnostic purposes.
Code D0419 is the assessment of salivary flow by measurement.
The purpose of this code is for the identification of low salivary flow in patients who are at risk for hyposalivation and xerostomia, as well as for effectiveness of pharmacological agents used to stimulate saliva production.
Xerostomia—The patient’s oral cavity may constantly feel dry.
Hyposalivation—The patient may have a decrease in salivary function.
These conditions can contribute to increases in the risk for dental diseases.
When filing an insurance claim with the patient’s dental insurance, the following information should be provided.
Describe what form of testing has been used to diagnose the patient. Here are a few common diagnostic testing devices:
- MyPerioPath by Oral DNA Labs
- Dentocult SM Strip Mutans by Orion Diagnostica
- CRT Bacteria by Ivoclar
- Saliva-Check buffer by GC America
Submit a clear written narrative that explains the benefits of the testing device and outlines the treatment plan with the desired prognosis that will help explain the need for treatment.
It is too early to know if insurance companies will adopt a standard protocol for processing and paying claims for preventive testing of salivary diagnostics.
It is strongly recommended that your office obtain a breakdown of benefits from the patient’s dental plan in order to determine coverage.
