There can be different kinds of costs associated with participating in clinical research. First, you may need routine care, such as doctor visits or hospital stays. Your standard health insurance rules will apply to those costs. For example, your health insurance should pay for care you could normally get. But if you don’t have coverage outside of your health plan’s HCP network, they may not pay for care if you travel to a different medical center to participate in research.There will also be research costs, such as the drug that’s being studied. Those costs are typically paid for by the study. Sometimes the study will also pay for all or part of your non-research costs. Some clinical trials include payments to participants.
