DMEPOS Competitive Bidding Program: Temporary Gap Period

All Medicare Round 2021 Durable Medical Equipment, Prosthetics, Orthotics, & Supplies (DMEPOS) Competitive Bidding Program (CBP) Contracts for Off-the-Shelf (OTS) back braces and OTS knee braces expire on December 31, 2023. Starting January 1, 2024, there will be a temporary gap in the DMEPOS CBP.

The Centers for Medicare & Medicaid Services (CMS) plans to conduct bidding for the next round of the DMEPOS CBP after going through notice and comment rulemaking to further strengthen the DMEPOS CBP.

For additional information on the gap period, please see the Temporary Gap Period (PDF) fact sheet and continue to monitor the CMS.gov and Competitive Bidding Implementation Contractor (CBIC) websites for updates.

Process Change

For dates of service beginning January 1, 2024, and after, there is a temporary gap period in the DMEPOS Competitive Bidding Program (CBP) for off-the-shelf back and knee braces. During the gap period, the prior authorization requirements for HCPCS codes L0648, L0650, L1833, and L1851 change and the competitive bid modifiers KV, J4, and J5 are no longer used. Treating practitioners now have the option to follow the prior authorization process with the standard timeframe of review, request an expedited review, or utilize the ST modifier, indicating acute/emergent need. For more information, refer to the Timeline and Updates section of the Prior Authorization and Pre-Claim Review Initiatives webpage on the CMS website. This process change only affects non-contract competitive bid suppliers who are practitioners/physicians, physical therapists, and occupational therapists.

Round 2021

Round 2021 of the DMEPOS Competitive Bidding Program began on January 1, 2021 and ended December 31, 2023. Round 2021 consolidated the competitive bidding areas (CBAs) that were included in Round 1 2017 and Round 2 Recompete. Round 2021 included 130 CBAs.

OTS back braces HCPCS codes: L0450, L0455, L0457, L0467, L0469, L0621, L0623, L0625, L0628, L0641, L0642, L0643, L0648, L0649, L0650, and L0651.

OTS knee braces HCPCS codes: L1812, L1830, L1833, L1836, L1850, L1851, and L1852.

The DMEPOS Competitive Bidding Program was mandated by Congress through the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA). The statute requires that Medicare replace the current fee schedule payment methodology for selected Durable Medical Equipment, Prosthetics, Orthotics and Supplies (DMEPOS) items with a competitive bid process. The intent is to improve the effectiveness of the Medicare methodology for setting DMEPOS payment amounts, which will reduce beneficiary out-of-pocket expenses and save the Medicare program money while ensuring beneficiary access to quality items and services.

Under the program, a competition among suppliers who operate in a particular competitive bidding area is conducted. Suppliers are required to submit a bid for selected products. Not all products or items are subject to competitive bidding. Bids are submitted electronically through a web-based application process and required documents are mailed. Bids are evaluated based on the supplier's eligibility, its financial stability, and the bid price. Contracts are awarded to the Medicare suppliers who offer the best price and meet applicable quality and financial standards. Contract suppliers must agree to accept assignment on all claims for bid items and will be paid the bid price amount. The amount is derived from the median of all winning bids for an item.

Former Competitive Bidding Area (CBA) Fee Schedule Adjusted fees for former Competitive Bidding Areas (CBAs) during a gap period in the DMEPOS Competitive Bidding Program (CBP) are determined by CMS. These items have been paid based on the Former CBA Fee Schedules since 2019
(see MM11064).

To view the Former CBA Fee Schedule, visit theCMS DMEPOS Fee Schedule page
  • Select the applicable file for the date of service
    • Under "File Name." Download that ZIP file, and you can open the files for CBA information, which are labeled
      • Former CBA Fee schedule
      • Former CBA National Mail Order diabetic testing supply fee schedule
      • Former CBA ZIP Code
Per 42 CFR Chapter IV, 414.210 - (10) - Payment adjustments for items and services furnished in former competitive bidding areas during temporary gaps in the DMEPOS CBP. During a temporary gap in the entire DMEPOS CBP and/or National Mail Order CBP, the fee schedule amounts for items and services that were competitively bid and furnished in areas that were competitive bidding areas at the time the program(s) was in effect are adjusted based on the SPAs in effect in the competitive bidding areas on the last day before the CBP contract period of performance ended, increased by the projected percentage change in the Consumer Price Index for all Urban Consumers (CPI–U) for the 12-month period ending on the date after the contract periods ended. If the gap in the CBP lasts for more than 12 months, the fee schedule amounts are increased once every 12 months on the anniversary date of the first day of the gap period based on the projected percentage change in the CPI–U for the 12-month period ending on the anniversary date.
Single Payment Amount

Suppliers will find the Single Payment Amounts (SPAs) for the Healthcare Common Procedure Coding System (HCPCS) codes included in Round 2021 of the DMEPOS Competitive Bidding Program on the Competitive Bidding Program Contractor (CBIC) website. Existing payment amounts have been replaced with these SPAs for the selected HCPCS codes in certain CBAs when Round 2021 was implemented on January 1, 2021.

On October 27, 2020, the Centers for Medicare & Medicaid Services (CMS) announced the single payment amounts for:

  • Off-the-shelf (OTS) back braces and OTS knee braces product categories ONLY
    • All other product categories were removed from Round 2021, including the National Mail Order. Please see the CMS announcement for additional information.

Traveling Beneficiary - KT modifier (Gap period begins 1/1/2024)

The Traveling Beneficiary Fact Sheet is available on the Medicare Learning Network and provides guidance on the rules for traveling beneficiaries and the use of the KT modifier from January 1, 2021, thru December 31, 2023.

The permanent residence is the address on file with the Social Security Administration (SSA). It is the address to which the SSA mails checks and/or correspondence to the beneficiary.

Four important CBP rules to know when a beneficiary needs an OTS back or knee brace while traveling:

  • Medicare payment is always based on the beneficiary's permanent residence.
  • Which supplier may furnish the OTS back or knee brace is determined based on where the beneficiary purchases the item.
  • The supplier that provides the OTS back or knee brace to the Medicare beneficiary must accept assignment (i.e., accept Medicare payment as payment in full) unless the beneficiary's permanent residence is not in a CBA and the beneficiary travels to an area that is not a CBA.
  • Suppliers must affix the HCPCS modifier "KT" to claims for OTS back or knee braces that are furnished to beneficiaries who permanently reside in a CBA and need a competitively bid item when they travel outside of the CBA where they reside.
