Pathology Lab Test Expert Witness qualifications and experience

Pathology Lab Test Expert Witness  work in this specialty includes usual customary and reasonable cost of care, appropriate coding and billing based on industry best practices and guidelines, payor policies and medical specialties as well as specific patient populations.  It may also include reviewing the test charge amounts versus national and regional charge averages, evaluating MUEs which are “Medically Unlikely Edits” as well as the cost of care based on national and regional rates.  In states where the standard allows experts to provide opinions on net reimbursement rates, 50th, 75th, and 90th percentile data may be presented.  Determining usual customary and reasonable costs for esoteric tests or any new area of medicine requires careful research to find data that represents the market rates in a specified A Core Based Statistical Area (CBSA). A CBSA is a U.S. geographic area defined by the Office of Management and Budget (OMB) that consists of one or more counties (or equivalents) anchored by an urban center of at least 10,000 people plus adjacent counties that are socioeconomically tied to the urban center by commuting..  Identification of providers who perform the tests in a similar time frame and setting may also be relevant.  Also, national correct coding initiative algorithms may be used to evaluate the tests versus national coverage determination and local coverage determination policies.
