Answer Summary:
Before the 2026 Competitive Bidding window opens, CMS contractors (NSC/NPE West/East) will conduct unannounced site visits to verify that bidding locations are operational. These auditors strictly enforce the 30 Supplier Standards. Common failures include missing hours of operation on the door, unstaffed “lunch hours,” and lack of visible inventory. A failed site visit results in immediate PTAN revocation. This guide provides a “Code Red” checklist to ensure your facility passes inspection.
Introduction: The Knock on the Door
It usually happens on a Tuesday morning at 10:30 AM.
A person with a clipboard walks into your DME lobby. They don’t have an appointment. They simply say: “I am here for a CMS Site Verification.”
In 2026, this is not a routine check-up. It is a “Purge Mechanism.”
CMS is actively looking to remove “shell companies” and “ghost locations” from the program before the Competitive Bidding window opens. If you fail this visit, your PTAN is revoked within 10 days, rendering you ineligible to bid.
You cannot “get ready” when they arrive. You must be ready now.
The “Instant Fail” Triggers
Auditors have a checklist. If you miss these basics, the audit is over in 5 minutes.
1. The “Closed Door” Policy
- The Rule: You must be open and staffed during your posted hours of operation.
- The Trap: Your posted hours say “Mon-Fri 9:00 – 5:00.” The auditor arrives at 12:30 PM. The door is locked because your staff is at lunch.
- The Verdict: FAIL. “Provider not operational.”
- The Fix: If you close for lunch, your sign must say “Closed 12:00 – 1:00.” If the sign says open, the door must be unlocked.
2. The “Virtual Office” Ban
- The Rule: You must have a physical location with a private entrance.
- The Trap: You operate out of a Regus, WeWork, or shared suite where the receptionist works for the building, not you.
- The Verdict: FAIL. You do not have “exclusive use” of the space.
3. The “Inventory” Check
- The Rule: You must maintain a “reasonable” amount of inventory on-site (unless you are strictly M/O).
- The Trap: The auditor asks to see your stock. You point to a laptop and say, “We drop ship everything.”
- The Verdict: FAIL (for Retailers). You must have at least some sample display inventory if you claim to serve walk-ins.
The Documentation “Grab Bag”
Once you pass the physical check, the auditor will ask for specific binders. If you can’t produce them in 15 minutes, they mark it as “Unavailable.”
The “Red Binder” Checklist:
- Liability Insurance Certificate: Must list CMS as a certificate holder.
- Complaint Log: A physical log of patient complaints (even if it’s empty, you need the log).
- Instruction Logs: Proof that you instructed patients on how to use the device.
- Surety Bond Copy: The actual bond document.
The “Staffing” Interview
The auditor will interview the person at the front desk.
- The Question: “Who is the Authorized Official?” “Where are the patient records kept?”
- The Danger: If you have a temp or a new hire who says, “I don’t know, I just answer the phones,” you risk a deficiency citation.
- The Fix: Train every employee on the “Site Visit Script.” They should know exactly where the Red Binder is.
