Implications of the initial Braidwood v. Becerra ruling for colorectal cancer outcomes:a modeling study

The Affordable Care Act (ACA) eliminated patient cost-sharing for United States Preventive Service Task Force (USPSTF) recommended services. However, if the US Court of Appeals for the Fifth Circuit fully upheld a US District Court ruling in Braidwood Management v. Becerra, 666 F. Supp. 3d 613 (N.D. Tex 2023), cost-sharing for USPSTF recommendations made after ACA passage would have been reinstated for more than 150 million people. The case would have reinstated cost-sharing for colorectal cancer (CRC) screening for ages 45-49 years and for polyp removal during (diagnostic) colonoscopy across all ages. Using the MISCAN-Colon model, we simulated the potential impact on CRC outcomes, assuming early-onset CRC trends and lower screening participation. An 8-percentage-point decline in screening participation could increase CRC incidence by 5.1% and CRC mortality by 9.1%, with slightly lower costs due to increased cost-sharing. Larger decreases in screening participation can result in higher costs from increased incidence and delayed diagnoses.
