The Centers for Medicare & Medicaid Services is proposing to lower Medicare reimbursements for implanted cardiac devices.

The proposed rule, which was released last week, would reduce reimbursements for stents by more than 30% and for defibrillators by as much as 20%. The rule would also include a smaller reduction in reimbursements for orthopedic products like replacement hips and knees.

CMS will accept public comments on the proposed rule for 60 days. It could implement a final rule in October.
