Hi, Walker we fall below the 30% rule for Medicare and bill for testing that we send out because we are unable to perform a component of the test requested. We at that point become the referring lab and bill the services with modifier -90 and now with New guidance from CMS include the performing lab information on the claim form (previously wasn't required.) But, there are some major payers for example BCBS AL that require the performing lab to bill for the service.
Dana, I am not able to open the link you provided, but I am anxious to see it. what I am essentially looking for is the CMS crosswalk for code 80374. I see some major labs using the G6042 to represent this test to Medicare, but the reimbursement is low for the actual D/L isomer test being performed.
Any assistance, guidance, knowledge is appreciated. Thank You
