CMS is reviewing claims and letting practices know which clinicians need to take part in MIPS, the Merit-based Incentive Payment System. MIPS is an important part of the new Quality Payment Program. In late April through May, practices will get a letter from the Medicare Administrative Contractor that processes Medicare Part B claims. This letter will tell the participation status of each MIPS clinician associated with the Taxpayer Identification Number or TIN in a practice. Clinicians should participate in MIPS for the 2017 transition year if they bill more than $30,000 in Medicare Part B allowed charges a year AND provide care for more than 100 Part B-enrolled Medicare beneficiaries a year. The Quality Payment Program intends to shift reimbursement from the volume of services provided toward a payment system that rewards clinicians for their overall work in delivering the best care for patients. It replaces the Sustainable Growth Rate formula and streamlines the “Legacy Programs” Physician Quality Reporting System (PQRS), the Value-based Payment Modifier (VM), and the Medicare Electronic Health Records (EHR) Incentive Program.
