What capitation is
Capitation is a prospective payment model. A provider organization, such as an IPA, medical group, or ACO, or a health plan receives a fixed dollar amount per enrolled member per month to cover a defined scope of care, regardless of how many services each member actually uses. The unit is the per-member-per-month (PMPM) rate. The Centers for Medicare and Medicaid Services (CMS) describes capitation as paying an organization a set amount per patient for a set period of time, in a way that holds it accountable for the cost and outcomes of that care.
The defining feature is the direction of risk. Under capitation, if the cost of care delivered comes in below the capitation received, the organization keeps the difference; if costs run higher, the organization absorbs the loss. That single mechanic transfers insurance and utilization risk from the payer to the provider.
How capitation works
Each month the payer multiplies the PMPM rate by the number of attributed members and pays that lump sum in advance. A rate of $50 PMPM across 10,000 members yields $500,000 a month to manage the covered care for that population. Rates are typically actuarial: a payer takes historical utilization and cost for a comparable population, trends it forward, and risk-adjusts it for the health status of the enrolled members. In Medicaid managed care, states must use "actuarially sound" rates that CMS approves; in Medicare Advantage, the per-person payment is built from county benchmarks, plan bids, rebates, and risk scores.
The three kinds of capitation
The label "capitation" covers a wide range of risk, and the scope of services in the rate is what matters:
- Primary-care capitation covers only primary-care services. It is the narrowest scope, used for example as the Primary Care Capitation Payment in ACO REACH.
- Professional capitation covers physician and professional services but usually not facility costs, and is often paired with shared savings or losses on the total cost of care.
- Global, or total-care, capitation is intended to cover the entire cost of care, including hospital and facility spend. This is full risk. Most failures happen when an organization takes global risk without the infrastructure to manage hospital utilization.
Capitation vs fee-for-service
Under fee-for-service, providers earn a separate payment for every visit, test, and procedure, so more volume means more revenue and the payer carries utilization risk. Under capitation the payment is fixed regardless of volume, so the provider carries the risk and is rewarded for delivering efficient, preventive, coordinated care. The incentive flips from "do more" to "do what is needed, efficiently."
Capitation is also distinct from shared savings. An upside-only Medicare Shared Savings Program ACO is still paid fee-for-service in real time and settles a partial, retrospective share of savings after the year closes. Capitation is prospective and puts the full budget at risk. The cash-flow and risk-tolerance differences between the two are large, and conflating them is a common error.
Why capitation rewards execution, not billing
Because the revenue is fixed and arrives in advance, margin under capitation is determined entirely by how well the organization manages total cost of care to the budget: accurate risk capture, closing quality gaps, steering avoidable emergency and inpatient utilization, controlling network leakage, and intervening on rising-risk members before they become expensive. A capitated organization is effectively a small insurer and needs the same discipline, including stop-loss and reserves, because a few catastrophic cases can erase a panel's margin.
How Pelica fits capitated risk
Capitation makes operational execution, not billing volume, the determinant of financial survival. Pelica is the AI operating system that risk-bearing organizations use to do that execution: one live record across risk, quality, pharmacy, and care management, with a copilot next to every team that closes gaps and follows up until work is resolved. At HealthCare Partners, the largest IPA in the country, teams cover two to three times more members without adding headcount and hold 96% medication adherence on the three triple-weighted Part D measures.
