Clinical coverage reviews will be based on third party clinical policy requirements for coverage. These policies include clinical criteria and information about coverage eligibility for related services. If a request needs review or requires additional clinical information, we will contact the ordering health care professional.

Prior Authorization, also known as a pre-authorization or pre-certification, is a clause in the health insurance policy that says the patient must get permission from their health insurance company before they receive certain health care services which includes specialized laboratory testing. This process was developed to help ordering health care professionals, laboratories and their patients receive a quicker coverage determination by giving them information: If a member’s benefit plan requires prior authorization. When additional clinical information is required to make a coverage decision. Whether the request meets third party’s clinical and coverage policy criteria.

Specialized laboratory testing that requires Prior Authorization can usually be found on the health plan’s website or by calling the health plan directly. Many genetic and molecular tests require Prior Authorization for outpatient services.

The health care professional who is ordering the testing is responsible for obtaining Prior Authorization for the specialized laboratory test. If the health care professional’s office does not obtain the necessary Prior Authorization before testing, the patient will be responsible for payment, which can range in cost from just under one hundred dollars to thousands of dollars based on the test ordered.
