Medicare coding and reimbursement for clinical laboratory services

Abstract

Medicare will continue to increase its efforts to cut spending through aggressive review of claims and the use of new fraud and abuse regulations. Providers must be especially careful to provide correct procedure codes that define precisely what services have been provided and accurate diagnosis codes that link those procedures or tests to an appropriate diagnosis. Medicare reimbursement rules for clinical laboratory procedures are explained, including the proper use of procedure and diagnosis codes. Coding and payment for new automated test panels are discussed, as well as the economic consequences of using smaller panels. Medicare coverage requirements, including medical necessity, are described, as well as the proper use of advance beneficiary notices and the Medicare appeals process.
