Ambulance Open Door Forum


The Ambulance Open Door Forum (ODF) addresses issues related to the payment, billing, coverage and delivery of services in the ambulance industry. The Ambulance Fee Schedule rules, rural and other ambulance payment enhancements, requirements for ambulance service certification and payment determinations, are just some of the many types of issues addressed within the forum. In addition, discussions differentiating the rules related to provider-based and independent ambulance services are facilitated. Timely announcements and clarifications regarding important rulemaking, agency program initiatives and other related areas are also included in the forums.
