Calculating Medicare Fee Schedule Rates

The Medicare Physician Fee Schedule (MPFS) uses a resource-based relative value system (RBRVS) that assigns a relative value to current procedural terminology (CPT) codes that are developed and copyrighted by the American Medical Association (AMA) with input from representatives of health care professional associations and societies, including ASHA. The relative weighting factor (relative value unit or RVU) is derived from a resource-based relative value scale. The components of the RBRVS for each procedure are the (a) professional component (i.e., work as expressed in the amount of time, technical skill, physical effort, stress, and judgment for the procedure required of physicians and certain other practitioners); (b) technical component (i.e., the practice expense expressed in overhead costs such as assistant's time, equipment, supplies); and (c) professional liability component.

The Centers for Medicare and Medicaid Services (CMS) determines the final relative value unit (RVU) for each code, which is then multiplied by the annual conversion factor (a dollar amount) to yield the national average fee. Rates are adjusted according to geographic indices based on provider locality. Payers other than Medicare that adopt these relative values may apply a higher or lower conversion factor.

How Medicare Part B Fees are Calculated by Providers

There are many factors providers must take into account when calculating the final payment they will receive for Medicare Part B services.

Standard 20% Co-Pay

All Part B services require the patient to pay a 20% co-payment. The MPFS does not deduct the co-payment amount. Therefore, the actual payment by Medicare is 20% less than shown in the fee schedule. You must make "reasonable" efforts to collect the 20% co-payment from the beneficiary.

Nonparticipating Status & Limiting Charge

There are two categories of participation within Medicare:

  • Participating providers who accept assignment, which means they accept the Medicare fee schedule rate; and
  • Nonparticipating providers who may choose not to accept assignment and may bill a slightly higher rate known as the limiting charge.

Both categories require that providers enroll in the Medicare program. Both participating and nonparticipating providers are required to file the claim to Medicare. Because federal law requires enrollment and claims submission for audiologists and SLPs, ASHA members should consider which form of participation best suits their business needs. You can change your status with Medicare by informing your contractor of your contracted status for the next calendar year, but only in November of the preceding year.

Participating Provider

When enrolling as a participating provider, you are required to bill on an assignment basis and accept the Medicare allowable fee as payment in full. Medicare will pay 80% of the allowable amount of the Medicare Physician Fee Schedule (MPFS) and the patient will pay a 20 % co-insurance at the time services are rendered or ask you to bill their Medicare supplemental policy.

For example, if the Medicare allowed amount is $100, but your rate is $160, you must accept $100 and cannot balance bill the patient for the $60 difference. In this scenario, Medicare would pay you $80, and the patient would pay you $20.

Nonparticipating Provider

As a nonparticipating provider, you are permitted to decide on an individual claim basis whether or not to accept the Medicare fee schedule rate (accept assignment) or bill the patient via the limiting charge. The limiting charge is a calculation that allows you to charge a slightly higher rate than the Medicare fee schedule; however, this rate may be hard for patients to pay if they are on fixed incomes. As with participating providers, nonparticipating providers cannot balance bill the Medicare beneficiary for the difference between the provider’s fee schedule and the limiting charge. In addition, civil monetary penalties can be applied to providers charging in excess of the limiting charge, as outlined in the Medicare Claims Processing and Program Integrity Manuals.

The allowable fee for a nonparticipating provider is reduced by five percent in comparison to a participating provider; in other words, the allowable fee for nonparticipating providers is 95% of the Medicare fee schedule allowed amount, whether or not they choose to accept assignment. However, the provider is allowed to bill the patient the limiting charge. The limiting charge is 115% of 95% of the fee schedule allowed amount. 

For example, if the Medicare allowed amount is $100, a nonparticipating provider starts at $95 (95% of the Medicare fee schedule rate) and then adds the limiting charge (115% of the nonparticipating provider rate). In this case, the most you can charge the patient is $109.25. The provider will submit an unassigned claim to Medicare; Medicare will pay 80% of the approved Medicare amount ($95) and the patient is responsible for 20% of the $95 plus the difference between the $95 and the limiting charge. However, you are responsible for collecting the full amount (the limiting charge) from the patient and Medicare will send reimbursement directly to the patient for the 80%.

Example: Calculating the Limiting Charge Using 2022 National Medicare Rates

CPT Code Fee Schedule Rate (non-facility) Nonparticipating Provider Rate (non-facility) Limiting Charge Billed to the Patient
92626 $89.98 $89.98 x 0.95 (95%) = $85.48 $85.48 x 1.15 (115%) = $98.30

In this example, Medicare will reimburse the patient 80% of the Medicare approved amount for nonparticipating providers ($85.48 x 0.80 [80%] = $68.38). The patient is fully responsible for the difference between the approved rate and the limiting charge ($98.30 - $68.38 = $29.92). You can also look up the limiting charge for your specific locality using the Medicare Physician Fee Schedule Look-Up Tool.

Facility & Non-Facility Rates

The MPFS includes both facility and non-facility rates. In general, if services are rendered in one's own office, the Medicare fee is higher (i.e., the non-facility rate) because the pratitioner is paying for overhead and equipment costs. Audiologists receive lower rates when services are rendered in a facility because the facility incurs overhead/equipment costs. Skilled nursing facilities are the most common applicable setting where facility rates for audiology services would apply because hospital outpatient departments are not paid under the MPFS.

Therapy services, such as speech-language pathology services, are allowed at non-facility rates in all settings (including facilities) because of a section in the Medicare statute permitting these services to receive non-facility rates regardless of the setting. ASHA asked CMS for clarification regarding audiology and CMS responded that the facility rate applied to all facility settings for audiology services.

Geographic Adjustments: Find Exact Rates Based on Locality

You may request a fee schedule adjusted for your geographic area from the Medicare Administrative Contractor (MAC) that processes your claims. You can also access the rates for geographic areas by going to the CMS Physician Fee Schedule Look-Up website. In general, urban states and areas have payment rates that are 5% to 10% above the national average. Likewise, rural states are lower than the national average.

Multiple Procedure Payment Reductions (MPPR)

Under the MPPR policy, Medicare reduces payment for the second and subsequent therapy, surgical, nuclear medicine, and advanced imaging procedures furnished to the same patient on the same day. Currently, no audiology procedures are affected by MPPR.

Therapy Services

MPPR is a per-day policy that applies across disciplines and across settings. For example, if an SLP and a physical therapist both provide treatment to the same patient on the same day, the MPPR applies to all codes billed that day, regardless of discipline. Under MPPR, full payment is made for the therapy service or unit with the highest practice expense value (MPFS reimbursement rates are based on professional work, practice expense, and malpractice components) and payment reductions will apply for any other therapy performed on the same day. For the additional procedures provided on the same day, the practice expense (i.e., support personnel time, supplies, equipment, and indirect costs) of each fee will be reduced by 50% (effective April 1, 2013) for Part B services in all settings. The professional work and malpractice expense components of the payment will not be affected. ASHA has developed three MPPR scenarios to illustrate how reductions are calculated.

MPPR primarily affects physical therapists and occupational therapists because they are professions that commonly bill multiple procedures or a timed procedure billed more than once per visit.
