DME Credentialing
Before a durable medical equipment supplier can bill Medicare for a single item, it has to post a $50,000 surety bond, earn accreditation from a CMS approved organization, and meet 30 separate supplier standards. That is the bar on day one. Before the first claim ever goes out. DME credentialing is the work of clearing that bar and staying over it.
We run that whole track for DMEPOS suppliers, pharmacies, and clinics adding an equipment line, so you get billing privileges and stay compliant instead of stuck.
What DME credentialing actually covers
DME is the short name. The program is DMEPOS: durable medical equipment, prosthetics, orthotics and supplies. Wheelchairs, hospital beds, oxygen, CPAP, braces, and the supplies that go with them.
Credentialing here means getting the supplier enrolled with Medicare and other payers and granted billing privileges, so the items you furnish actually get paid. It is a different track from physician credentialing. The forms, the contractor, the bond and the accreditation rule are all specific to suppliers, which is why a general credentialing checklist does not cover it. Same discipline behind the medical credentialing services we run for every provider type, pointed at the DMEPOS world.
What Medicare requires from a DMEPOS supplier
Here is the checklist we work through to get a supplier enrolled and billing:
Miss one and the application stalls or comes back. We assemble all of it, file it, and answer the requests that come back mid review.
Where your application goes now
This is the detail a lot of older guides still get wrong. For years the 855S went to the National Supplier Clearinghouse. The NSC was retired on November 7, 2022.
DMEPOS enrollment now runs through two National Provider Enrollment contractors, split at the Mississippi River. Suppliers east of it file with NPE East, run by Novitas Solutions. Suppliers west of it file with NPE West, run by Palmetto GBA. We file with the right one for your location, because sending it to the wrong contractor just burns weeks.
The $50,000 surety bond, explained
The bond trips people up because of the number. You are not writing a $50,000 check. A surety bond is a bonded instrument with an annual premium: the surety issues the $50,000 guarantee, and you pay a yearly premium to carry it. The catch is that it is required per enrolled NPI, so a supplier running multiple NPIs posts a bond for each.
There are exemptions. Certain physicians and practitioners who furnish DMEPOS items under their own NPI, and some therapist owned practices, do not have to post the bond or carry accreditation for items they personally furnish. We confirm where you fall before we file, so you neither skip a required bond nor pay for one you do not owe.
Accreditation coordination
Accreditation has to come from a CMS approved accreditation organization, and it is not a one time box to tick. Your accrediting body resurveys you on a cycle, at least every three years, and the survey is unannounced. We line your accreditation up alongside the 855S so the two pieces land together, and we keep your documentation survey ready.
Commercial and Medicaid DME enrollment
Medicare is the headline, not the whole job. Plenty of DME suppliers also enroll with state Medicaid programs and commercial payers, each on its own application and its own cycle. We panel you across the plans your patients carry, the same way our payer enrollment team does for every payer type, so a claim has somewhere to land no matter who covers the patient.
Keeping it from lapsing
Enrollment is not set and forget. DMEPOS suppliers revalidate their Medicare enrollment every three years, and that revalidation can trigger another unannounced site visit. Let a bond lapse or an accreditation expire and Medicare can suspend payment fast. We track the dates, file the revalidations, and keep the bond and accreditation current so billing never goes dark.
What we handle, what you supply
We own the maze. You hand us your documents, your signatures where a form needs them, your NPI status, and the states and payers you care about. We register or confirm the NPI, build and file the CMS-855S, coordinate accreditation, handle the surety bond paperwork, clear the site visit, secure your PTAN, and keep revalidation and reaccreditation on schedule.
Need your NPIs set up or a state license sorted first? That sits with our medical license and NPI registration team.
