Medicare Advantage (MA) enrollment among patients receiving dialysis has surged following the passage of the 21st Century Cures Act, which lifted prior restrictions on enrollment. As MA becomes the plurality payer for dialysis, understanding its implications for patients, providers, and policymakers is critical. MA offers out-of-pocket spending caps and additional services not covered under fee-for-service (FFS) Medicare. Some plans also prioritize care coordination, which may improve patient outcomes.
