Clarification on Medicare O2 Modifiers

Shared by our DAC Region D chair, we see that CGS who is the DME MAC Contractor for Regions B & C offers billing instruction for Providers struggling with the new Medicare Oxygen Modifier topic. Our partners at DACD expect that Noridian will also release a clarification soon. NOTE: the change we see is that DME MACs have rescinded direction formerly give to Providers to advise that Question 5 be answered with an "average liter flow" rather than the highest liter flow. AAHomecare's legistlation & regulatory groups were vital in challenging CMS & DME MACs to provide clarity with relieves the burden of unnecessary recertification for thousands of Providers.
