Companies that are Medicare-approved suppliers enroll in Medicare, meet Medicare standards and follow payment guidelines by accepting assignment, states Medicare.gov. To find Medicare-approved suppliers in their area, Medicare enrollees can use their ZIP codes to search the supplier directory at Medicare.gov. Alternatively, enrollees can find approved or contract suppliers by calling 1-800-MEDICARE, notes the American Diabetes Association.
To locate Medicare-approved suppliers, Medicare enrollees can access the supplier directory, enter their ZIP code and select the product categories for which they need suppliers, explains Medicare.gov. The search engine displays a supplier list along with the addresses, telephone numbers and distances of the facilities from the entered ZIP code. Some suppliers have icons that indicate they participate in the Medicare competitive bidding program, which allows enrollees to buy from contract suppliers only and limits the amounts suppliers can charge for medical equipment. The locations have map and direction links that searchers can click on to receive help finding the facilities.
Medicare-approved suppliers that accept assignment and contract suppliers in the competitive bidding program can only charge Medicare enrollees the Medicare Part B 20 percent coinsurance and any unpaid yearly deductible, according to Medicare.gov. Before purchasing medical equipment, Medicare enrollees should ensure suppliers accept Medicare assignment or suppliers may charge them more than Medicare-approved amounts, cautions the American Diabetes Association.
