Understand the numbers

Medicare-approved amount vs. billed charge, Medicare payment, and what you may owe

These four numbers answer different questions. Knowing which one you are looking at is the first step toward a useful cost comparison.

Billing education, not medical advice or a coverage determination

Quick comparison

Four numbers that are easy to confuse

Term What it means What it does not tell you
Billed or submitted charge The amount a provider puts on a claim before Medicare or another payer applies its payment rules. It is not automatically the amount Medicare approves, the amount Medicare pays, or the amount the patient owes.
Medicare-approved amount The amount Original Medicare recognizes for a covered item or service. A provider who accepts assignment agrees to accept this amount as full payment for that covered service. It is not necessarily the provider’s charge, Medicare’s share, or the patient’s final share.
Medicare payment The amount Medicare pays toward an approved claim after applicable payment and cost-sharing rules. It does not include amounts paid by the patient, Medigap, Medicaid, an employer plan, or another insurer.
Patient out-of-pocket responsibility The amount the patient may owe after coverage rules, deductibles, coinsurance or copayments, other insurance, and noncovered services are considered. It cannot be determined from a provider’s charge or a single Medicare-approved amount alone.

The allowed amount

What “Medicare-approved” means

Original Medicare uses an approved amount as the payment basis for a covered item or service. When a physician, other provider, or supplier accepts Medicare assignment, that provider agrees to accept the Medicare-approved amount as full payment for the covered service. Medicare, the patient, and sometimes another insurer may each pay part of that amount.

For many Part B clinician services, Medicare says a beneficiary usually pays 20% of the Medicare-approved amount after meeting the Part B deductible. That is a general rule, not an estimate for every claim. Preventive-service rules, other insurance, provider assignment, the type of facility, coverage decisions, and additional services can change what someone owes.

Why the charge can be higher

A provider’s submitted charge is a different benchmark

The submitted charge is the amount reported on the claim. It may be much higher than the Medicare-approved amount because Medicare applies its own coverage and payment rules. Comparing providers by submitted charge can therefore answer a different question than comparing their average Medicare-approved amounts.

A high submitted charge does not establish that Medicare or a patient paid that amount. Likewise, a Medicare-approved amount does not reveal the price a commercial insurer negotiated or a provider’s cash-pay price.

A simplified example

How the numbers can relate

Suppose a provider submits a $500 charge for one covered Part B service, while the Medicare-approved amount is $200. In a simplified situation where the deductible has already been met, assignment is accepted, and no special rule applies, Medicare might pay about $160 and the patient’s 20% coinsurance would be $40.

The $500 charge is not the patient bill in this example. The $200 approved amount is not the Medicare payment. And the $40 is not a reliable estimate if the deductible, secondary coverage, noncovered services, or other bills differ.

MedCostCompare data

Which number appears in our comparisons

MedCostCompare uses the CMS Medicare Physician & Other Practitioners provider-and-service release published in 2026, covering services delivered in calendar year 2024. The provider amounts in our comparisons are calculated from that release’s average Medicare-approved amount—not its average submitted charge or average Medicare payment.

The release year and the service year describe two different dates: CMS published this source file in 2026, and the claims summarized in it are for services delivered during calendar year 2024.

Important: A displayed amount may represent only a clinician or other identified billing component. It is not a complete episode price and does not predict what a particular patient will owe.

After a claim

Where to find the actual Medicare claim amounts

For people with Original Medicare, the Medicare Summary Notice shows services billed to Medicare, what Medicare paid, and the maximum amount the patient may owe the provider. It is not itself a bill. Medicare recommends comparing the notice with provider bills and receipts.
