MA plans pass capitation down to physician groups. This lesson covers global risk, the deepest provider risk arrangement in American healthcare.
Medicare Advantage is where the largest number of providers actually bear deep financial risk, because plans do not keep all of it. They pass it downstream to physician groups under arrangements known as delegated or global risk. This is the risk spectrum from the introductory course, taken to its end point.
How it works
Under a global risk arrangement, the MA plan gives a physician organization the bulk of the capitation it receives for that group’s attributed members. The group then bears responsibility for the total cost of those members’ care, risk-adjusted annually according to their coded conditions.
The group is now doing what the finance course described: managing a population within a fixed budget, holding reserves, and bearing the consequences of its own efficiency. It has become, functionally, an insurer for its panel.
Where it is established
This is not theoretical. The global risk model has operated in South Florida and Southern California since the late 1990s, and in those regions roughly half of Medicare Advantage members receive care under it. Nationally, about 10 percent of MA plan members are in such arrangements.
That geographic concentration is itself informative: global risk grew where provider organizations had the scale, capital, and experience to sustain it, exactly the preconditions the finance course identified.
Why groups accept it
Worth remembering: the appeal is not only financial upside. Groups under global risk receive a large, predictable payment up front and escape much of the friction of fee-for-service, the billing, the coding for individual claims, and the need to get individual services preapproved by the plan. A group that holds the risk is largely the one deciding what care is appropriate. For physicians frustrated by utilization management, that autonomy is a substantial draw.
The risks that come with it
Everything the finance course warned about applies. A group under global risk needs scale for the law of large numbers, capital against a bad year, stop-loss for catastrophic cases, and the data infrastructure to manage a population. Groups that take global risk without those foundations can fail, and some have. The arrangement transfers both the upside and the exposure.
Key takeaways
- Under global risk, an MA plan passes the bulk of its capitation to a physician group, which becomes responsible for total cost of care.
- The model has operated in South Florida and Southern California since the late 1990s, covering about half of MA members there and roughly 10 percent nationally.
- Groups gain predictable revenue and autonomy from plan utilization management, and take on the scale, capital, and stop-loss requirements of an insurer.

In a global risk arrangement, what does a physician group receive from the MA plan?
Under global risk the plan passes the bulk of its capitation to the provider group, which then bears responsibility for the total cost of care, the deepest form of provider risk in practice today.
