"Value-based care" (VBC) is any arrangement in which a provider's pay depends partly or wholly on the total cost and quality of care for a group of patients, not only on the number of services billed. It ranges from small quality bonuses on top of fee-for-service to full capitation, where a provider group takes a fixed monthly payment per member and is responsible for nearly all of that member's medical spending. The idea has had bipartisan support for 15 years, and CMS has said it wants every traditional Medicare beneficiary in an accountable-care relationship by 2030. The business record is mixed. Integrated systems (Kaiser), disciplined senior-focused clinics (Oak Street Health, ChenMed) and ACO enablers (Aledade, Privia Health) built real businesses. A wave of 2020–21 public listings (agilon health, Cano Health, Bright Health, CareMax, Babylon Health) lost most or all of their value when Medicare Advantage revenue was cut and medical costs rose at the same time. This section explains the contract types, the math of shared savings and capitation, why risk-bearing companies are really small insurers, and why so many failed. The supporting files compute a full-risk clinic's J-curve and MSSP payouts, and dissect the failures.
