The provider retains the copy designated “Institution Copy” and submits the remaining
copies of the completed Form CMS-1450 to its A/B MAC (A) or (HHH), managed care
plan, or other insurer. Where it knows that a managed care plan will pay the bill, it sends
the bill and any necessary supporting documentation directly to the managed care plan
for coverage determination, payment, and/or denial action. It sends to the A/B MAC (A)
or (HHH) bills that it knows will be paid and processed by the A/B MAC (A) or (HHH).
