Fee-for-Service

Fee-for-Service Payment in Health Care

Under fee-for-service, the money a doctor, practice or hospital earns rises with every consultation, test, procedure or vaccination it bills, so income follows activity item by item. That design makes it the clearest case of a payment method that rewards doing more, and the usual reference point for judging capitation, case-based payment and bundled payment. Health economists study it to explain how doctors respond to fees and to design the schedules and caps around them. It also matters in costing care, because a fee is a price paid by a purchaser and need not match the resources a service uses. Other methods are compared on the provider payment page.

The item of service as the unit of payment

The World Bank manual edited by Langenbrunner, Cashin and O'Dougherty defines fee-for-service as reimbursing the provider for each individual service provided. Without a fixed fee schedule, providers bill purchasers for all costs incurred, which the manual notes is often called retrospective cost-based payment in the United States. With a fixed fee schedule, as in Canada, Germany and Japan, the provider receives the set fee for a predefined service whatever it cost to produce. The WHO South-East Asia brief on strategic purchasing likewise describes fees fixed in advance for each service or group of services.

Fee-for-service describes how the provider is paid, not who pays. The World Bank manual notes that under insurance the patient may owe a deductible, a copayment or coinsurance before the purchaser pays the rest, which is the subject of cost sharing. A simple surplus identity shows what the provider gains from each billed item.

$$\pi = \sum_{s=1}^{S} (f_s - c_s)\, q_s - F$$

where $\pi$ is the provider's surplus for the period, $S$ is the number of billable services, $f_s$ is the fee for service $s$, $c_s$ is the variable cost of one unit of $s$, $q_s$ is the number of units billed and $F$ is the fixed cost of the practice. Each extra unit adds $f_s - c_s$, so the incentive attached to a service is the gap between its fee and its marginal cost, not the fee alone.

How fee schedules price each service

A fee schedule turns a list of codes into a list of prices. The Medicare Payment Advisory Commission (MedPAC) payment basics note on the physician payment system, revised October 2026, states that under the Medicare physician fee schedule the unit of payment is generally the individual service, among about 9,000 coded services. Each service carries relative value units for clinician work, practice expense and professional liability insurance, adjusted for local input prices and multiplied by a conversion factor, which in 2026 is USD 33.57 for qualifying participants in an advanced alternative payment model and USD 33.40 for other clinicians. Medicare pays 80% of the fee schedule amount for most services, and the beneficiary owes 20% coinsurance. The origin of the weights is on the resource-based relative value page.

Carrin and Hanvoravongchai report that Japan's social health insurance applies a national fee schedule to nearly all procedures and services, that regular revision since 1981 has kept fees relatively low, and that the overall fee level is linked to a global budget negotiated between government ministries.

English general practice uses fees at the edges of a capitated contract. The General Medical Services Statement of Financial Entitlements Directions 2026 require NHS England to pay a practice an item of service fee of GBP 12.06 for each dose of a routine childhood vaccination and GBP 10.06 for each dose in the other listed programmes, for doses given between 1 April 2026 and 31 March 2027, while some other vaccines are paid within the global sum. This is the blended payment the WHO brief describes, a small fee inside primary care capitation to counter underprovision of priority prevention.

Why fee-for-service raises activity

The World Bank manual states that a fixed fee schedule gives the provider an incentive to increase the number of services and reduce the inputs per service, and that services which generate a surplus will be expanded most quickly. The manual adds that fees which do not track costs can produce an emphasis on high-technology care relative to primary care, as it reports for China.

The theory rests on the principal-agent problem in healthcare. McGuire and Pauly built a model of physician behaviour with demand inducement in which physicians maximise profit when income effects are absent and seek a target income when income effects are very strong. Yip states the inducement hypothesis as a prediction that physicians respond to cuts in income by raising the volume of services when the income effect is strong and negative. Without that income effect a lower fee narrows the margin on a service and less of it is supplied, and the gap between the two predictions is the core of supplier-induced demand.

Studies have found both responses. Gruber and Owings linked the 13.5% fall in United States fertility between 1970 and 1982 to a shift by obstetricians towards caesarean delivery, the more highly reimbursed alternative. Yip, using a panel of physicians in New York and Washington states, found that those whose incomes were cut most by Medicare fee reductions performed more coronary artery bypass grafts, in both the Medicare and private markets. Clemens and Gottlieb, using a 1997 change in Medicare's geographic payment areas, found that on average a 2% increase in payment rates led to a 3% increase in care provision, with elective procedures such as cataract surgery responding much more strongly. They estimated economically small effects on patient health, with limited precision.

Carrin and Hanvoravongchai report that when Copenhagen general practitioners were moved onto partly fee-based payment in 1987, after full capitation, the services that generated extra fees increased significantly. A Cochrane review by Gosden and colleagues, with only four eligible studies, found more primary care visits under fee-for-service than capitation and judged the generalisability unknown.

Spending, access and the budgets built around fees

The World Bank manual reports that fee-for-service correlates with a pronounced increase in volume and overall health expenditure. Carrin and Hanvoravongchai rate its cost-containment potential as low but note that hard budgets can neutralise the upward effect. They report that Germany's budget ceiling cut fees in proportion when physicians' services grew too fast and that Canadian provinces combine fee schedules with expenditure caps. The arithmetic of a fee cut offset by higher volume is on the cost containment page.

The method has real strengths. The World Bank manual notes that it is easy to implement with little capacity and is thought to improve access in underserved areas and for priority services, and that where costs are understood fees can be set to encourage cost-effective services, as in Japan. The WHO brief judges it most useful when productivity, supply and access are top priorities and cost control is a low priority.

Worked example of one care pathway priced at fees and at resource cost

All numbers in this example are illustrative. A practice bills three services. A consultation earns GBP 40 and uses GBP 25 of variable resources, a blood test earns GBP 20 and uses GBP 6, and a minor procedure earns GBP 150 and uses GBP 50, giving margins of GBP 15, GBP 14 and GBP 100.

1. Current pathway A. Each patient has three consultations and two tests. The payer pays 3 × 40 + 2 × 20 = GBP 160, the resources cost 3 × 25 + 2 × 6 = GBP 87, and the practice keeps 160 − 87 = GBP 73.

2. New pathway B. Each patient has one consultation and one procedure. The payer pays 40 + 150 = GBP 190, the resources cost 25 + 50 = GBP 75, and the practice keeps 190 − 75 = GBP 115.

3. Two cost views. At fees, pathway B costs the payer 190 − 160 = GBP 30 more per patient. At resource cost it uses 87 − 75 = GBP 12 less. The practice margin rises by 115 − 73 = GBP 42, which is the payer's extra GBP 30 plus the GBP 12 of resources saved.

4. Cost-effectiveness. If pathway B gains 0.002 QALYs per patient, the payer's incremental cost-effectiveness ratio is 30 / 0.002 = GBP 15,000 per QALY. At resource cost pathway B is cheaper and more effective, so it shows dominance over pathway A.

5. Budget impact. For 1,000 patients a year the payer spends 1,000 × 30 = GBP 30,000 more, resource use falls by 1,000 × 12 = GBP 12,000, and the practice gains 1,000 × 42 = GBP 42,000.

The switch costs the payer money while saving resources and raising the practice's margin, and only the margin explains why the practice would promote it. The gap between the two cost views is set by how far fees depart from resource cost.

Fees as cost evidence in economic evaluation

Itemised claims data are attractive for measuring resource use, but the prices on claims are payment amounts. Finkler, writing about hospital bills, warned that charges may bear little resemblance to economic cost and that using them as a proxy can lead to unwarranted conclusions about efficiency, so actual resource consumption should be used as the measure of cost.

The right figure depends on the perspective. The NICE technology appraisal manual (PMG36) states in section 4.4.1 that reference-case costs should relate to NHS and personal social services resources, valued using the prices relevant to them, and in section 4.4.9 it describes national average unit costs of healthcare resource groups as a way to reduce the need for local micro-costing. A budget impact analysis for a purchaser that pays fees counts the fees, because those leave its budget, while a model of resource use should check that a fee tracks the resources used before adopting it as a unit cost.

Fee-for-service and neighbouring payment methods

The methods differ by the unit that triggers payment. Fee-for-service pays per item, per diem payment per inpatient day, case-based payment per admission, bundled payment per episode, capitation per enrolled person and salary per period of employment. Paying separately for each component of care is what makes the method unbundled.

United States usage needs care. MedPAC's payment basics note on Medicare Advantage contrasts private plans, which Medicare pays a capitated rate, with the traditional fee-for-service programme, so "Medicare fee-for-service" names a whole programme, of which physician fee schedule payments made up just over 15% of spending in 2025, according to MedPAC's physician payment note. Quality-linked adjustments to fees belong to value-based purchasing.

Common misreadings of fee-for-service

Most errors treat the fee as the whole story. Behaviour and spending also depend on the costs behind each fee and the controls around the schedule.

1. Fee-for-service does not mean the patient pays. It describes how the provider is paid, and a public scheme, insurer or patient may be the purchaser.
2. A fee is not a cost. Fees can sit well above or below the resources a service uses, as the worked example shows.
3. More services are not proof of inducement. Higher activity can reflect better access, and evidence on health effects is limited.
4. A fee cut does not reliably save money. Target-income behaviour predicts more volume, so savings depend on the response and on any budget cap, and claims adjudication rules also shape what is finally paid.
