Medicare home oxygen U S Government Accountability Office

"Studies have found that Medicare payment rates for home oxygen exceeded other payers' rates. Congress has reduced home oxygen payment rates, capped rental payments after 36 months, and directed the Centers for Medicare & Medicaid Services (CMS), which administers Medicare, to use competitive bidding. GAO was asked to examine Medicare home oxygen payment policy. GAO describes how Medicare pays for home oxygen; the effect on Medicare's payments of using other methodologies and rates; and changes in beneficiary access. GAO reviewed federal laws and regulations, industry-reported costs, Medicare claims data and payment data from selected private insurers, the Department of Veterans Affairs (VA), and CMS's competitive bidding program.
