Promoting and protecting the health and safety of all Idahoans

Laboratory Testing

Idaho Medicaid coverage includes genetic testing or molecular pathology services performed in a credentialed lab, but only when such testing is considered under current standards to be reasonable and necessary for the diagnosis and potential treatment of an illness, disease, or condition.


The following types of genetic testing are not covered by Idaho Medicaid:

  • Tests performed for screening purposes only, in the absence of signs, symptoms, or personal history of disease or injury

  • Tests that are done solely to diagnose a patient, and will not impact medical decision-making for the patient or the patient’s treatment plan

  • Tests performed for the purposes of genetic counseling or family planning

  • Tests that do not meet the definition of medical necessity as set forth in IDAPA
