Should federal agencies require stricter prior authorization for new Medicare equipment suppliers?
Beginning October 15, 2026, the Centers for Medicare and Medicaid Services will mandate probationary prior authorization for new Medicare DMEPOS suppliers. This policy also extends to businesses that undergo ownership changes on or after that date.
Why it matters
The Centers for Medicare and Medicaid Services implemented this program to protect the Medicare trust fund from improper payments. By requiring advance review, the agency aims to ensure that only qualified providers receive reimbursement for specific items.
The new policy applies to all newly enrolled Medicare suppliers and businesses with ownership changes after October 15, 2026. These entities must submit to advance review for specific HCPCS codes defined by CMS.
