What it means
The contrast is with fee-for-service, where the provider bills separately for each consultation, test or procedure. Fee-for-service rewards volume, while capitation rewards keeping the covered population healthy and out of expensive settings.
That single change in the payment formula reshapes clinical and commercial behaviour. Revenue under a capitated contract is highly predictable, which is its main attraction to a finance team.
Registered numbers multiplied by the agreed rate gives next month's income before a single patient walks in, which makes staffing and budgeting far easier. Costs, by contrast, become the volatile side of the equation.
Rate setting is where the deal is won or lost. Payer and provider negotiate a rate per member per month based on the expected mix of ages, conditions and historical usage, and a rate built on the wrong population assumption can turn a profitable contract into a loss.
Risk adjustment, which lifts the rate for sicker registered groups, is the standard protection. The obvious danger is under-treatment, because every avoided service improves the provider's margin in the short run.
Contracts therefore carry quality measures, minimum service standards and audit rights, with part of the payment withheld until targets are met. Reputation and professional licensing act as the longer-term counterweight.
Stop-loss cover is the other standard safeguard and small providers should insist on it. It caps the provider's cost on an individual case above an agreed threshold, so one patient needing extremely expensive treatment cannot wipe out the whole year.
Without it, a practice with a few thousand registered members is carrying insurance risk it is not capitalised to hold.
In practice
Real-world examples.
Example
A regional health insurer pays a network of clinics $52 per member per month for 25,000 registered members. The clinics invest in evening appointments and nurse-led chronic disease reviews, because reducing hospital referrals improves their margin under the fixed payment.
Example
A dental group accepts a capitated contract for 8,000 employees of a large manufacturer at $18 per member per month. Take-up in the first year is only 40%, so the group earns $1,728,000 while treating far fewer people than the rate assumed and makes an unusually high margin.
Example
A small clinic signs a capitated contract without stop-loss cover and two registered patients require treatment costing $190,000 between them. The fixed monthly payments cannot absorb that, the year closes at a loss, and the clinic renegotiates the next contract with a $25,000 per-case cap.
Formula
Calculation
Capitation revenue = registered members x rate per member per month x number of months
Contract margin = capitation revenue - cost of services delivered
A primary care group signs a capitated contract covering 4,000 members at a rate of $45 per member per month for a full year. Revenue is 4,000 x 45 x 12 = $2,160,000. Those members make an average of 2.5 visits each over the year, so 4,000 x 2.5 = 10,000 visits, and at a fully loaded cost of $160 a visit the service cost is 10,000 x 160 = $1,600,000. The margin is 2,160,000 - 1,600,000 = $560,000, or 560,000 / 2,160,000 = 25.9% of revenue. If average visits rose to 3.5, the cost would be 14,000 x 160 = $2,240,000 and the same contract would lose $80,000, which shows how sensitive the result is to usage.Case study
Seen in the real world.
Marlowe Street Health is an illustrative, fictional group practice offered a capitated contract for 6,000 members at $38 per member per month, giving annual revenue of 6,000 x 38 x 12 = $2,736,000. The practice manager accepted the rate because it exceeded the previous year's fee-for-service income from a similar population.
What the analysis missed was the mix of people being signed up. The population handed over was older and had a higher rate of chronic conditions than the practice's existing patients, and usage ran at 4.1 visits per member instead of the 2.8 assumed, giving 24,600 visits at $115 each, or $2,829,000 of cost.
The contract lost $93,000 in its first year. Marlowe Street renegotiated with a risk-adjusted rate of $44 for members over 65 and a stop-loss threshold of $20,000 per case, and the illustrative lesson is that the rate is only meaningful alongside a hard look at who is actually being registered.
Watch out
Common mistakes.
- Accepting a rate per member per month based on the provider's existing patients rather than on the actual registered population, which is often older or sicker.
- Signing without stop-loss cover, so a single catastrophic case can consume the margin on thousands of members.
- Treating capitation income as guaranteed, when revenue falls immediately if members disenrol or move to another provider.
Questions
People also ask.
What does per member per month mean?
It is the fixed sum paid for each registered person each month, whether that person uses the service every week or never attends at all.
How does risk adjustment work?
The payer raises the rate for groups expected to need more care, typically by age, diagnosis or deprivation measures, so the provider is not penalised for taking on a sicker population.
Is capitation only used in healthcare?
It is most established there, but the same logic appears in managed information technology support, facilities contracts and some legal retainers, where a fixed fee per user or per site covers unlimited calls on the service.
