Medicare reimbursement for clinical trial services: understanding Medicare coverage in establishing a clinical trial budget.

In designing and setting up a clinical trial, investigators and private sponsors must take into account what costs will or will not be covered by third-party insurers and government payment programs like Medicare and Medicaid. Failure to "cost out" the clinical trials accurately can yield one of two results: either third-party payors are billed improperly, or even illegally, for experimental care, or significant research-related care is not billed, with either the investigating institution, or the research subjects themselves, shouldering the cost. Unfortunately, because Medicare has established different coverage principles to be applied depending on the type of trial being conducted, costing out the trial is not an easy task. This Article looks at the various Medicare coverage principles as they apply to clinical trials, including the 2000 National Coverage Decision and the recent expansion in coverage for Class A Investigational Devices created by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. The Article then examines how the Medicare secondary payor rule, which states that providers may not bill Medicare for items or services when another party has primary responsibility for those services, relates to clinical trails in light of recent commentary. The Article concludes with the presentation of a general framework that investigators can use to establish a clinical trial budgeting and billing system.
