A/B MAC (A) - Medicare Part B Services Paid Under Various

100.1 - A/B MAC (A) - Medicare Part B Services Paid Under Various Fee Schedules (Rev. 2075, Issued: 10-28-10, Effective: 01-01-10, Implementation: 01-28-11) The legislative change in MMA §630 of 2003, which was effective January 1, 2005, and indefinitely extended by §2902 of the ACA, allows IHS providers to bill for other Medicare Part B services, not covered under §1848 of the Act. In an effort to clarify that these charges are not included in the AIR (which is the general method of payment) and to allow these facilities to acquire the appropriate certifications, IHS providers, including CAHs were allowed to begin billing separately for the following Medicare Part B services: • Prosthetic and orthotic devices (beginning July 1, 2005); • Surgical dressings (beginning July 1, 2005); • Influenza, pneumococcal, and hepatitis B vaccines (beginning January 1, 2006); and • Ambulance services (beginning January 1, 2005). The enactment of BIPA allowed for separate billing of certain services by physicians and practitioners, including physical therapy, occupational therapy, and speech-language pathology (including diagnostic audiology services).
