Medicareâs Coding System for Medical Billing. APC stands for Medicareâs Ambulatory Payment Classification, the coding system that hospitals use to bill the federal government for services provide to Medicare and Medicaid patients. Every procedure or medication given to Medicare and Medicaid patients has its own unique code that must be submitted to Medicare by the hospital in order to receive reimbursement for services.
This difference between the automatic transmission and CVT is the number of gears. The automatic is limited to 4 to 9 gear ratios and there are definite or noticable changes between the gears and this is felt during driving. The CVT has what is termed an infinite number of ratios ranging from low to high and the transmission move through the gears steeplessly according to the driving situation.
Manual vs. automatic transmissions. A manual transmission has a set of gears that are lined up on a shaft. As the gearshift and clutch, located inside the car, are manipulated by the driver, the gears move into place. As the clutch is released, power from the engine is transmitted to the wheels. The amount of power, or torque, is dependent upon the gear that was chosen. With an automatic transmission, the gears are lined up on the shaft, but the gears change by manipulation of the gas pedal inside the car.
