DMEPOS Competitive Bidding Program (CBP)

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) required

Medicare to replace the fee schedule payment methodology for selected DMEPOS items with a

competitive bidding program implemented in areas throughout the country. The DMEPOS CBP

helps Medicare establish sustainable prices, saves money for beneficiaries and taxpayers, and

limits fraud, waste, and abuse in the Medicare program. In addition to the cost savings, there

are several beneficiary protections that help to guarantee access to competitively bid DMEPOS

including requiring contract suppliers to provide equal access to all DMEPOS items and

services included in the supplier contract to every beneficiary residing in the competitive bidding

area.  Please click this link and go to page 21 for more information. CMS Competitive Bidding

Providing Orthoses Prior to Surgery – Reminder

CGS wants to remind suppliers and providers that orthotic devices are not covered if they do not meet the coverage criteria outlined in the Local Coverage Determinations (LCDs) for the HCPCS code prescribed at the time of service.

Devices provided prior to the start of medical necessity (for example, before the surgery), will not meet the coverage criteria. After surgery, if there is documentation of the medical necessity for the orthotic device(s), you can provide the item, keeping in mind there are many other payment rules related to the claim.

For orthotic devices that require Prior Authorization (PA) (L0648, L0450, L1832, L1833, and L1851), do not submit PA requests prior to the start of medical necessity (for example, before the surgery). After surgery, if the medical record documentation shows an emergent need for the device(s), you can submit an expedited request. If an expedited request is not feasible, append the ST modifier to the claim to bypass PA. Claims submitted with the ST modifier are subject to 100% prepayment review.
