Risk-based payments
Payment arrangements in which a healthcare provider accepts financial responsibility for a defined share of the cost of care for a patient population, rather than receiving a fixed fee per service regardless of cost. Risk-based payments can take several forms: capitation (fixed PMPM for all care), shared savings with downside risk (sharing both gains and losses against a benchmark), or global capitation (full cost of care responsibility including hospitalization and specialist care).
Why this matters for your clinic
Risk-based payments change the fundamental economics of running a clinic. Under fee-for-service, revenue is determined by how many services you deliver. Under risk, revenue is determined by how efficiently you manage the total cost of care for your attributed population. If your patients use fewer resources than the risk rate assumes, you profit. If they use more, you absorb the loss. The financial management skill required is completely different.
Accepting risk without adequate data is one of the most common financial mistakes in value-based care transitions. To take risk responsibly, you need to know your cost per attributed patient by category (primary care, specialist referrals, emergency, hospital), your per-patient utilization trends, and your ability to influence the care patterns that drive the highest costs. Practices that enter risk contracts on actuarial assumptions rather than their own historical data frequently discover within 12 months that the contract is losing money.
Risk-based payment arrangements vary widely in how much risk is transferred to the provider. Professional risk covers only services the practice directly delivers. Global or full risk covers all services including referrals, inpatient, and post-acute care. Downside corridors and stop-loss provisions limit exposure on high-cost outlier patients. Carefully modeling the maximum financial exposure at each risk structure is a precondition for any contract negotiation.
What good looks like
CMS publishes risk track structures and minimum risk exposure thresholds for each CMMI model. Commercial risk arrangements are privately negotiated. NAACOS (National Association of ACOs) and the American Academy of Family Physicians publish resources on risk contract evaluation for primary care practices.
Example
A primary care group accepts a partial professional risk contract for 4,000 commercial HMO members. They receive $38 PMPM ($1.824M per year) to cover all primary care services they directly provide. The actuarial model assumes 3.2 visits per member per year at an average cost of $140 per visit, totaling $1.79M in expected costs and a $34K margin. If actual utilization runs to 3.8 visits per member per year, expected costs rise to $2.13M, turning the projected margin into a $306K loss on flat revenue.
From Sorso
We require a minimum of 12 months of clean per-patient cost data before we will help a client model a risk contract. The single most common mistake we prevent is helping a practice see that their assumed cost per member is materially below their actual historical cost before they lock into a contract rate.
