A new primary care initiative will free physicians to care for Medicare patients the way they want to, officials at the Centers for Medicare and Medicaid Services said Monday. The 5-year initiative, known as the Comprehensive Primary Care Plus model, will "give doctors the freedom and flexibility to practice medicine the best way they know how, to return to what matters most to doctors and their patients," said Patrick Conway, MD, CMS chief medical officer, on a phone call with reporters. The Comprehensive Primary Care Plus initiative includes two tracks, each with different requirements and payment options. Both will require practices to give patients 24/7 access to care and to deliver preventive care. Practices in both tracks also will be given upfront incentive payments and will be able to keep them or be required to pay them back, depending on how well they perform.
