Under the Competitive Bidding Program, the contract supplier is responsible for maintaining rented equipment. Maintenance and servicing of beneficiary-owned equipment may be performed by any supplier with a valid Medicare billing number. All Medicare-enrolled suppliers, including contract suppliers, must be in compliance with all of the supplier standards and be accredited. The Medicare-enrolled supplier is always responsible for meeting the supplier standards under 42 CFR 424.57, regardless of whether it chooses to make repairs or perform maintenance directly or through a subcontractor.
