Do you know the difference between an NSC Site Visit and an Accreditation Survey?

As a Medicare Part B Supplier you will go through periodic onsite surveys by the National Supplier Clearinghouse and your Accreditation Organization. These two types of surveys are separate and distinct from one another and not allowing either to take place could have negative effects on your ability to bill Medicare.


No worries, many Medicare Part B Suppliers are because they have so many different surveyors coming in to their locations.

The Accreditation Organization Survey will verify that you are following all of the policies and procedures required by them to remain in good standing.

The National Suppler Clearinghouse (or NSC Site Survey) will verify that you are abiding by the 30 Medicare Supplier Standards (always refer to CMS/Palmetto for the current version). This survey can be conducted to all Medicare Part B suppliers, whether you are Accredited or not. They will be specifically asking for several policies and forms, including:

  1. Beneficiary Complaints.
  2. A Model Warranty Form can be found on the NSC Website.
  3. A “Capped Rental, Inexpensive or Routinely Purchased Items Notification” form can be found on the NSC Website.

To ensure your continued ability to bill Medicare for DMEPOS and prevent you from being removed from the Medicare program, it is critical that you allow them to conduct their survey. The NSC site visitor is not affiliated with your accreditation organization. They will identify themselves and present you with a Site Visit Acknowledgement Form.
