## TL;DR

Outside US Medicare and Medicaid, joining a trial can leave the patient or hospital paying for the ordinary care that goes with it, and billing uncertainty blocks participation in middle-income countries. Requiring every insurer and public system to cover routine care costs removes a hidden barrier.

## Summary

Legislation or payer policy guaranteeing coverage of routine patient care costs during trial participation, as US Medicare has since 2000 and Medicaid since the CLINICAL TREATMENT Act (effective 2022), extended to all private insurers, to national health systems that lack explicit rules, and to public insurers in middle-income countries where trial participation can be blocked by billing uncertainty.

## Fields

- Kind: Idea
- Last checked: 2026-09-08
- Hypothesis: Jurisdictions adopting explicit routine-cost coverage will see an increase in trial enrolment among publicly insured and lower-income patients within two years.
- Rationale: Coverage uncertainty is a documented reason sites do not offer trials to certain patients and hospitals decline to host them. Removing it is cheap for payers because routine care would be paid for anyway.
- Proposed test: Compare Medicaid-insured trial enrolment before and after the CLINICAL TREATMENT Act across states with and without prior coverage mandates; replicate in a middle-income country adopting the rule.
- Maturity: being-tested-at-scale
- Actor: payer
