Ambulance Services Furnished by Providers of Services

10.1.4 - Ambulance Services Furnished by Providers of Services (Rev. 1, 10-01-03) A3-3114, B3-2120.1, HO-236.1 The A/B MAC (A) is responsible for the processing of claims for ambulance service furnished under arrangements by participating hospitals, skilled nursing facilities, and home health agencies. Since provider ambulance services furnished “under arrangements” with suppliers can be covered only if the supplier meets the above requirements, the A/B MAC (A) may ask the A/B MAC (B) to identify those suppliers who meet the requirements. Where the "under arrangement" supplier also supplies ambulance services directly to Medicare beneficiaries, i.e., services that are not pursuant to an arrangement with a provider, the A/B MAC (A) contacts the A/B MAC (B) to ascertain whether it has already determined whether the crew and ambulance requirements are met. In such a situation, the A/B MAC (A) should accept the A/B MAC (B)’s determination without pursuing its own investigation.
