Which federal legislation changed the timely filing period for Medicare Part B claims?

The Affordable Care Act is the legislation that notably changed the timely filing period for Medicare Part B claims, extending it to allow healthcare providers and suppliers a more substantial window to submit claims. This adjustment aimed to streamline the claims process and ensure that providers receive appropriate compensation for services rendered, thereby improving healthcare access and quality. By providing a longer timeframe for filing claims, the Affordable Care Act has allowed practitioners more flexibility, reducing the likelihood of denials due to missed deadlines. This change was part of broader reforms intended to enhance the efficiency of the Medicare program and improve healthcare delivery for beneficiaries.
