Medical Coding

Answer: D - HCPCS Level II ambulance service modifiers represent where the patient was picked up and where the patient was dropped off. They are two letters, like all other HCPCS Level II modifiers, but the first letter represents where the patient was picked up and the second letter represents where the patient was transported to or dropped off. The locations and letters are found at the beginning of the A-section of the HCPCS manual.
