It is not too late to start participating in the 2012 Physician Quality Reporting System (PQRS) and potentially qualify to receive an incentive payment equal to 0.5% of an eligible professional's total Medicare Part B allowed charges for services furnished during the reporting period. A new six-month reporting period using the registry submission option began on July 1, 2012. In addition, there are still ways to participate in the 12-month reporting period using claims, registry or EHR submission. For additional information, see the "Deadlines and Reminders" section of AOA website PQRS page.
