💰 Clinical Trial Costs & Insurance Coverage

Coverage for clinical trial participation varies depending on your health insurance policy, state legislation, and whether specific procedures are investigational research or routine medical care. Under federal law (Affordable Care Act § 2709), health insurers generally cannot drop coverage or refuse to pay for routine patient care costs incurred in approved clinical trials.
