NPI Type 1 vs. Type 2: The Foundational Error That Kills Contracts

Answer Summary:

A common error for new DME providers is confusing Type 1 (Individual) and Type 2 (Organization) National Provider Identifiers (NPIs). You cannot bill Medicare for DME using a Type 1 NPI (like a doctor’s personal ID). You must incorporate and obtain a Type 2 NPI. Furthermore, “Group Practices” must ensure that all billing is routed through the Type 2 NPI to avoid payment rejections and liability issues.

Introduction:

“I have an NPI, so I’m ready to bill.”

Stop.

Which NPI do you have?

In the rush to launch, many clinician-owners (Pharmacists, PTs, MDs) try to use their personal NPI to start a DME company.

This triggers an immediate rejection.

Medicare DMEPOS is an “entity-based” enrollment. You are not enrolling a person; you are enrolling a business.

The Difference Explained

• Type 1 (Individual): Linked to a human (SSN). It travels with you.
  • Use: For the ordering physician to sign the prescription.
• Type 2 (Organization): Linked to a business (EIN). It stays with the company.
  • Use: For the DME supplier to submit the bill.

The “Sole Proprietor” Trap

• The Scenario: You are a Sole Proprietor. You technically can use a Type 1 NPI to bill…
• The Warning: Don’t do it. If you use your Type 1, you cannot sell the business later (because the NPI is you). You also expose your personal assets to audits.
• The Fix: Always incorporate (LLC/Inc), get an EIN, and get a Type 2 NPI.

Linking Type 1s to Type 2s

If you have a group practice (e.g., an O&P clinic with 3 Orthotists):

• The Business bills (Type 2).
• The Orthotist renders (Type 1).
• The PECOS Step: You must “reassign” the Type 1 benefits to the Type 2 entity in PECOS. If you miss this step, the claims will deny as “Provider not linked to group.”
