Prior Authorization Process for Certain Durable Medical Equipment, Prosthetic, Orthotics, Supplies (DMEPOS) Items

Update 3/15/17:

CMS has posted additional resources for suppliers, physicians, and their patients on the new subpages on the menu on the left. These include introductory letters, frequently asked questions, and a flow chart of the prior authorization process. There is also a chart displaying the special tracking and education process for prior authorization review requests that are not approved due to submissions that include documentation errors but where the patient seems to otherwise meet Medicare’s coverage criteria. Suppliers submitting documentation with these errors will receive individualized education and are encouraged to resubmit their request to ensure patients continue to receive the necessary covered services.

CMS will host the first in a series of DMEPOS Special Open Door Forum calls on Thursday, March 16, 2017 at 2:00PM Eastern Time, for DMEPOS suppliers. As announced previously in the Federal Register, CMS has selected two items to be subject to prior authorization under the Prior Authorization of Certain DMEPOS Items program (Group 3 power wheelchairs - K0856 and K0861). On this call, we will outline the process for submitting a prior authorization request to your designated Durable Medical Equipment Medicare Administrative Contractor (DME MAC), the timeframes for the DME MAC to render their prior authorization decisions, and the process for subsequent claim submissions. DMEPOS suppliers and other participants will be encouraged to submit questions and provide feedback that may be incorporated into our supporting documents, such as frequently asked questions or the operational guide. CMS will post slides in the ‘Downloads’ section below in advance of the call. Click here for more information on this Special Open Door Forum.

CMS will host a separate DMEPOS Special Open Door Forum call for physicians and other Medicare practitioners on Tuesday, March 21, 2017 at 2:00PM Eastern Time. CMS will post more information on that call soon.

Welcoming Feedback to Support Program Transparency while Empowering Patients and Providers

CMS is committed to launching the narrowly tailored Prior Authorization Program of Certain DMEPOS Items program in an open and transparent manner that serves and protects patients and the health care providers that care for them.  CMS has the opportunity to learn from patient and provider experience and welcomes feedback as a critical part of this process.  We look forward to an ongoing dialogue to help us gather feedback and learn how the program can best meet patients’ needs. 

To enhance this dialogue with both patients and providers, and to support program transparency, CMS will soon be launching a new website for DMEPOS Prior Authorization with helpful tools for patients, suppliers, and physicians. These patient-centered resources aim to improve transparency; protect access to care; and support direct engagement with patients, suppliers, and physicians. CMS will begin adding these new resources to this website starting on or before March 20, 2017. CMS will contract with an independent evaluator to fully analyze the impacts of prior authorization, including effects on patient care; access to services; or the patient, supplier, or physician/practitioner experience.

Please note that all initial prior authorization decisions should be made in no more than 10 days. In cases where that timeframe could seriously jeopardize the life or health of the beneficiary, you may request an expedited review. Decisions for substantiated expedited reviews should be made within 2 business days.

CMS has established a dedicated mailbox to solicit feedback from all stakeholders as this program gets underway. We encourage patients and providers to address all feedback to:

Through this mailbox, CMS is also seeking feedback on how the current medical necessity criteria for power wheelchairs aligns with documentation requirements. Is a supplier able to accurately assess whether the patient meets the medical necessity criteria? How can the documentation requirements associated with the coverage decision be improved? One of the resources CMS will soon post is a Provider Checklist for Prior Authorization of Power Wheelchairs. CMS would like feedback on the checklist, and whether it helps suppliers, physicians, and practitioners understand what information is needed for Medicare to pay for the item.

Prior Authorization Request Submission Process

Suppliers who are ready to submit a prior authorization request for a date of service of March 20, 2017 or later can use the operational guide in the Downloads section to access necessary information and processes.

CMS Finalizes Rule Creating Prior Authorization Process for Certain Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) Items (CMS 6050-F)

Update 12/19/16:

CMS announced in the Federal Register (here), as published on December 21, 2016, the selection of two items of durable medical equipment to be subject to required prior authorization beginning on March 20, 2017:

  • K0856: Power wheelchair, group 3 std., single power option, sling/solid seat/back, patient weight capacity up to and including 300 pounds
  • K0861: Power wheelchair, group 3 std., multiple power option, sling/solid seat/back, patient weight capacity up to and including 300 pounds

Suppliers or beneficiaries submitting claims in one of the 4 states listed below must receive prior authorization before the item is furnished or a claim is submitted, as a condition for payment:

  • Illinois
  • Missouri
  • New York
  • West Virginia

CMS also announced its intent to expand the prior authorization process for codes K0856 and K0861 nationwide in July 2017.

For information about the prior authorization process specific to these items, stakeholders may access support materials in the download section below.

The Centers for Medicare & Medicaid Services (CMS) today issued a final rule that would establish a prior authorization process as a condition of payment for certain durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS) items that are frequently subject to unnecessary utilization. This prior authorization process will help ensure that certain DMEPOS items are provided consistent with Medicare coverage, coding, and payment rules.  CMS believes the final rule will prevent unnecessary utilization while safeguarding beneficiaries’ access to medically necessary care.

Under the final rule, the prior authorization process will require the same information necessary to support Medicare payment today, just earlier in the process.  It will not create new clinical documentation requirements. The prior authorization process assures that all relevant coverage, coding, and clinical documentation requirements are met before the item is furnished to the beneficiary and before the claim is submitted for payment. This helps ensure that beneficiaries are not held responsible for the cost of items that are not eligible for Medicare payment. CMS believes prior authorization is an effective way to reduce or prevent questionable billing practices and improper payments for DMEPOS items.  Access is preserved in this rule by having both specified timeframes for review and approval of requests, and an expedited process in cases where delays jeopardize the health of beneficiaries.


CMS has had longstanding concerns about the improper payments related to DMEPOS items.  The Department of Health and Human Services’ Office of the Inspector General and the U.S. Government Accountability Office have published multiple reports indicating questionable billing practices by suppliers, inappropriate Medicare payments, and questionable utilization of DMEPOS items. CMS has addressed these issues in recent years through the implementation of the DMEPOS Competitive Bidding Program, as well as heightened screening of suppliers, as authorized by the Affordable Care Act.

In addition to those actions, CMS recently expanded a 3-year prior authorization demonstration program for power mobility devices (PMDs). The demonstration began in 2012 in 7 states with high incidences of fraudulent claims and improper payments. In 2014, the demonstration was expanded to 12 additional states. Based on claims processed from September 1, 2012 through December 31, 2015, monthly expenditures for the PMD codes included in the demonstration decreased from: $12 million to $3 million in December 2015 in the original 7 demonstration states; $10 million in September 2012 to $2 million in December 2015 in the 12 additional expansion states; and $10 million in September 2012 to $3 million in December 2015 in the non-demonstration states. CMS believes the decrease in spending is due in part to national DMEPOS suppliers adjusting their billing practices nationwide (not just in the demonstration states) to comply with CMS policies based on their experiences with prior authorization in the demonstration states.

This final rule further addresses questionable utilization and improper payments by creating a prior authorization process for certain DMEPOS items beyond PMDs.  Under Section 1834(a)(15) of the Social Security Act, the Secretary has the authority to develop and periodically update a list of DMEPOS items that the Secretary determines, on the basis of prior payment experience, are frequently subject to unnecessary utilization and to develop a prior authorization process for these items. The final rule implements this authority by creating:  a “Master List” of items that meet specific criteria and are potentially subject to prior authorization; a “Required Prior Authorization List,” a subset of items on the Master List; and a prior authorization program for the Required Prior Authorization List items.


The Master List is the set of 135 DMEPOS items identified as being frequently subject to unnecessary utilization.  Items that meet the following criteria are included on the Master List and thus potentially subject to prior authorization: items on the DMEPOS Fee Schedule with an average purchase fee of $1,000 or greater, or an average rental fee schedule of $100 or greater, (adjusted annually for inflation) and the subject of:

  • HHS Office of the Inspector General (OIG) or U.S. Government Accountability Office (GAO) reports that are national in scope and published since 2007, or 
  • Comprehensive Error Rate Testing Program’s Annual Medicare Fee-for-Service Improper Payment Rate Reports and/or the Supplementary Appendices for the Medicare Fee-for-Service Improper Payment Rate Reports since 2011.

The list is self-updating annually such that items on the DMEPOS Fee Schedule that meet the payment threshold are added to the list when the item is the subject of an OIG or GAO report of a national scope or a future CERT DME Service Specific Report. Items will remain on the list for 10 years, but can be removed sooner if the purchase amount drops below the payment threshold.  After 10 years, items can remain on the list or be added back to the list if a subsequent report identifies the item as frequently subject to unnecessary utilization.


Presence on the Master List does not automatically create a prior authorization requirement for that item. In order to balance minimizing provider and supplier burden with protecting the Medicare Trust Funds and beneficiary access, CMS will initially implement prior authorization for a subset of items on the Master List (referred to as “Required Prior Authorization List”). CMS will publish the Required Prior Authorization List in the Federal Register with at least 60 days’ notice before implementation of prior authorization for those items.


Prior authorization will be required for those DMEPOS items on the Required Prior Authorization List.  The process requires all relevant documentation to be submitted for review prior to furnishing the item to the beneficiary and submitting the claim for processing. CMS or its contractors will review the prior authorization request and provide a provisional affirmation or non-affirmation decision.  A claim submitted with a provisional affirmation decision will be paid so long as all other requirements are met.  A claim submitted with a non-affirmation decision or without a decision will be denied.  Unlimited resubmissions of prior authorization requests are allowed.

Medicare or its review contractor will make a reasonable effort to render an initial prior authorization determination within 10 business days and will make a reasonable effort to render a resubmission prior authorization determination within 20 business days.  These are maximum timeframes and will be adjusted downward for items that require less time for making a determination.  An expedited review process will be available to address circumstances where applying the standard timeframe for making a prior authorization decision could seriously jeopardize the life or health of the beneficiary. The request for an expedited review must provide rationale supporting the request.

CMS will issue specific prior authorization guidance in sub-regulatory communications.
