Why Medicare Rates Are the Benchmark for Medical Prices

Every service in the fee schedule, identified by its CPT or HCPCS code, is assigned relative value units, or RVUs, that express how resource-intensive it is compared with every other service. The RVU total has three components: physician work, covering time, skill, and intensity; practice expense, covering staff, equipment, rent, and supplies; and malpractice expense, covering liability insurance costs.

A complex surgery carries far more total RVUs than a routine office visit, and that ratio, not a dollar figure, is the fee schedule's core statement about value. The relative weights are reviewed and updated through a public process, with input from a physician committee convened by the American Medical Association, and the results are published for anyone to inspect. Practice expense RVUs also differ by setting: a procedure performed in a physician's own office carries higher practice expense than the same procedure in a hospital, where the facility bills separately for overhead. That is why this site shows facility and non-facility rates.

It costs more to run a practice in Manhattan than in rural Mississippi, so Medicare adjusts each RVU component by a geographic practice cost index, or GPCI. Each of Medicare's payment localities has three GPCIs, one each for work, practice expense, and malpractice, reflecting local wages, rents, and liability premiums.

The adjustment is deliberately moderate; it narrows geographic differences rather than mirroring them fully, and the work GPCI in particular is compressed by policy. But it means the same CPT code pays somewhat different amounts in San Francisco, Houston, and Des Moines. When MedCostCheck asks for your ZIP code, this is why: it maps you to a Medicare locality and applies that locality's GPCIs so the rate you see is the one that actually applies where you live.

After RVUs are geographically adjusted, they are multiplied by a single national dollar amount called the conversion factor. That one number converts the entire relative value scale into actual payments, and it is updated each year through rulemaking, subject to statutory formulas and periodic congressional intervention.

The complete formula is simple to state: payment equals the geographically adjusted RVU total times the conversion factor. Everything on this site flows from that arithmetic, using the current year's published RVU file, GPCI file, and conversion factor from the Centers for Medicare and Medicaid Services. There is no estimation or modeling in the rates you see here; they are the computed fee schedule amounts. Note that the fee schedule is the payment for the service itself; a Medicare patient's share, typically 20 percent coinsurance under Part B after the deductible, is a separate matter of benefit design.

Private insurance rates are set by negotiation between insurers and providers, and negotiating power varies enormously. A dominant hospital system that an insurer cannot exclude from its network can command high rates; a small independent practice cannot. The consistent research finding is that commercial insurance pays more than Medicare for the same services, often substantially more, with hospital care showing a wider gap than physician services and enormous variation from market to market and contract to contract.

Several forces sustain the gap. Providers argue Medicare rates sit below their costs for some services, making commercial payers the margin that keeps the doors open. Consolidation among hospitals and physician groups has strengthened provider leverage. And prices for specific services stayed opaque for decades, though federal transparency rules for hospitals and insurers have begun exposing negotiated rates to daylight. None of this changes the practical point: the Medicare rate is the stable floor from which every other price is a markup.

Because commercial prices are multiples of Medicare, the Medicare rate gives you an instant reasonableness test for any bill or quote. Look up the CPT code on this site for your ZIP code, then compare. A cash price at or modestly above the Medicare rate is generally a fair deal. A charge that is many multiples of Medicare deserves scrutiny and, for shoppable services, comparison shopping.

In a negotiation, the anchor works best stated plainly: "Medicare pays about this amount for this procedure in this area. I can pay that amount, or close to it, promptly. Can we settle at that figure?" Billing offices know exactly what Medicare pays; you are not introducing an exotic concept, you are signaling that you know the reference price. Many hospitals also tie their financial assistance discounts to amounts derived from what Medicare or insurers pay, so the benchmark carries weight inside their own policies too.

Be fair with the tool. Some services genuinely cost more to deliver than Medicare pays, and a small practice accepting Medicare-level cash from you is giving you a good price, not a windfall. The goal is not to demand the floor everywhere; it is to recognize when a price is defensible and when it is unmoored.

The fee schedule covers professional services: physician visits, procedures, imaging interpretation, and similar work. It does not by itself capture hospital facility payments, which run through separate Medicare payment systems, or drug prices, or your specific insurance plan's negotiated rate, deductible position, and coverage rules. A Medicare rate is a benchmark for the service, not a prediction of your exact out-of-pocket cost.

Used with that understanding, it is the most powerful single number in health care shopping. Before any scheduled procedure: get the CPT codes, look up the Medicare rates here, ask providers for their price, and judge the quotes against the benchmark. Ten minutes of arithmetic puts you in a stronger position than the vast majority of patients ever occupy.
