*Medically necessary COVID-19 RT-PCR testing, including testing for symptomatic individuals and testing for individuals with suspected exposure to the virus, such as those who may have tested positive from a rapid test and require a confirmatory RT-PCR test, may be reimbursable by your insurance company under Federal law, or, if uninsured, may be covered in full by the Health Resources and Services Administration (HRSA), an agency of the U.S. Department of Health and Human Services (HHS), subject to available funding. Note that as of March 22, 2022, HRSA will no longer accept requests for testing reimbursement for uninsured individuals due to lack of funds. In the event that your insurer or HRSA does not cover or reimburse you for the cost of the test, you are responsible for cost of the test and KSL Diagnostics may bill you directly for the cash price, currently $150.
