DMEPOS Accreditation and Enrollment: What Each Gate Actually Checks

DMEPOS accreditation requirements govern the quality standards a supplier must meet, the products and locations its approval covers, and how often it must be surveyed. Medicare enrollment adds a separate examination of the business, its owners, licenses and operations. For someone inside a healthcare supplier, the revealing question is how those files compare with the work people actually do. A survey report describes one operation. Staffing records, delivery records and claims may describe another.

Who Checks the Supplier, the Product and the Claim?

The Centers for Medicare & Medicaid Services sets the framework, but different organizations make the decisions inside it. An accreditation certificate, an enrollment approval and a claim payment answer different questions.

The agency’s accreditation fact sheet separates the accreditor from the enrollment contractor. They operate independently. The enrollment contractor verifies that accreditation covers the products and services listed in the application.

The coding decision adds another distinction. For certain equipment, including negative pressure wound therapy pumps, Medicare requires the product to have the coding contractor’s approval for the billed code. An accredited business can still have a product-classification problem.

Medicare Advantage has a different screening gap. In its February 2026 request for information, the Centers for Medicare & Medicaid Services asked whether plans would prefer suppliers to be accredited and enrolled as they are in traditional Medicare. It cited inspector general work examining equipment billing by suppliers outside traditional Medicare enrollment.

What Does DMEPOS Accreditation Check?

Accreditation checks supplier business services and product-specific services against the agency’s quality standards. The standards include separate requirements for respiratory equipment, mobility equipment, and products such as custom orthotics and prosthetics. Unless exempt, a supplier must be accredited before the enrollment contractor will process its application.

The accreditor reviews the application and supporting documents, including the organizational chart and licenses, and conducts an unannounced on-site survey. Its accreditation decision draws on both the submitted information and the visit. That puts the people doing the work, their qualifications and the services the business actually provides alongside its written policies.

The final rule bars accreditors from counting mock files, fictional patient records, simulated documentation, templates or duplicate patient records as patient medical records in a survey.

The scope matters. Accreditation identifies particular products and services. Each location, including a subcontracted location, must have the required accreditation and its own enrollment. A company name on a certificate leaves the product and location questions to be answered.

Even the accrediting organization’s approved scope can differ. In the agency’s January 9, 2026 list, the National Association of Boards of Pharmacy had a narrower scope that omitted the wheelchair and complex rehabilitation appendix. A pharmacy using that accreditor could not simply add power mobility under its existing approval. The business’s ambitions and the accreditor’s authority have to meet.

The Patient’s Phone Call Is a Separate Question

The restriction on unsolicited beneficiary telephone calls sits in the supplier standards. The quality-standards document does not contain a telemarketing or advertising standard. That distinction matters when someone points to accreditation as the answer to a question about purchased leads.

The Medicare telephone-solicitation restriction connects prohibited calls to payment for the resulting items. Written permission and qualifying prior relationships matter to that rule. The accreditation file and the patient-contact records therefore tell different parts of the story.

What Enrollment Checks at Each Location

Enrollment checks whether the supplier is an identifiable, operating business that meets Medicare’s supplier standards. The Medicare enrollment application makes that examination concrete: it asks about the business location, products, accreditation, ownership, managing control, adverse actions, insurance and bond.

For a freestanding supplier, the site standards require at least 200 square feet, a visible sign, public access, staff during posted hours and a primary business telephone. The lease, sign, staffing schedule and actual use of the premises answer the physical-business question.

The public-hours requirement is at least 30 hours a week, with exceptions for professional practices and custom orthotics and prosthetics suppliers. Sharing space with another Medicare supplier or provider is restricted, with limited exceptions.

State licensing follows the item or service being furnished. The federal supplier standard incorporates those state requirements, and the application identifies the states served and the licenses required there. For a business shipping across state lines, the address of its headquarters is only part of the licensing picture. Clinical work performed inside a patient’s home also has to be matched to the qualifications of the person who performed it.

The standards require comprehensive liability insurance of at least $300,000. The Centers for Medicare & Medicaid Services’ enrollment guidance separately specifies a $50,000 surety bond for each National Provider Identifier, subject to exceptions.

The operating records reach beyond the premises. Suppliers must maintain proof of delivery, beneficiary instruction and complaint records. The application records where medical files are stored and identifies an outside billing agency. Using that agency leaves the supplier responsible for the accuracy of the claims submitted on its behalf.

Enrollment information changes, including accreditation changes, must be reported within 30 days. Enrollment revalidation remains a three-year cycle. That timetable serves a different purpose from the annual accreditation survey.

Who Is Exempt From DMEPOS Accreditation?

The agency exempts specified professionals and products from accreditation, and pharmacies have a separate conditional route. The identity of the supplier matters alongside the equipment it furnishes.

The professional list includes physicians, nurse practitioners, physician assistants, physical therapists and occupational therapists. Opticians, orthotists and prosthetists also appear on the exemption list. Exempt products include inhalation drugs, pump-infused drugs, home health agencies’ medical supplies and certain other Part B drugs.

A pharmacy may seek an exemption through an attestation to its enrollment contractor. Among the conditions are DMEPOS billings averaging less than 5% of total sales over three years, enrollment for at least five years, and no adverse action.

Professionals exempt from accreditation still face the quality standards. Surety-bond exceptions have their own conditions: the application distinguishes, for example, a physician furnishing items to the physician’s own patients from a freestanding durable medical equipment business.

The same product can therefore arrive through businesses facing different accreditation and bond requirements. For an insider, the question is which supplier billed for it and which exemption that supplier claimed.

Annual DME Accreditation Survey and Existing Three-Year Cycle Transition

The annual durable medical equipment accreditation survey rule took effect January 1, 2026, with resurvey and reaccreditation required at least once every 12 months. The agency’s accreditation fact sheet says an existing three-year cycle issued before that date continues until it expires. The annual cycle begins then.

The former interval came from agency guidance. The final rule put the shorter interval into the supplier standards. The agency also made clear that a survey can occur before the anniversary of the previous visit.

The accreditation’s issue date and expiration date show when the supplier moves into the annual cycle.

The same change ended the former three-month operating period before an accreditor’s visit to a new location. Existing suppliers opening a new location must now have it surveyed before accreditation. A new product category also goes back to the accreditor for accreditation and a survey if needed. Neither expansion is merely a change to the sales catalog.

Multiple locations multiply the work. The agency retained separate accreditation for each location and rejected a different survey cycle merely because a business has many sites. It can allow surveys of a sample of sites, but only in writing. A chain’s accreditation record therefore has to be read with the survey’s actual coverage in view.

Why CMS Tightened Oversight of Accreditors

Suppliers choose and pay the private organizations that inspect them. That commercial relationship makes the accreditor’s independence a practical issue for the people preparing applications, commissioning surveys and paying invoices.

In the final rule, the Centers for Medicare & Medicaid Services cited a March 2025 criminal guilty plea by an accreditation inspector who admitted accepting bribes and self-dealing. The agency’s account of the criminal case describes cash payments to speed accreditation, supplier companies established in family members’ names to conceal the inspector’s interest, and inspections of suppliers the inspector owned directly or indirectly. Some companies were sold after Medicare enrollment increased their value.

The inspector was helping create the asset being sold: a business able to bill Medicare. That is why the ownership file, survey assignment and payment to the inspector belong in the same examination.

The new oversight rules require separation between an accreditor’s consulting and accreditation operations, including separate staff. Accreditation staff and surveyors may not market the organization’s consulting services to accreditation clients. The agency also expanded the information accreditors must provide and its ability to review their operations. The control now reaches the organization deciding who passes.

What Is the DME 36-Month Ownership Rule?

The 36-month ownership rule for durable medical equipment suppliers requires a buyer to enroll as a new supplier and obtain a new accreditation survey when it acquires majority ownership within that period after initial enrollment or the last qualifying ownership change. The existing Medicare billing privileges do not pass to the buyer.

The ownership threshold is more than 50% direct ownership. The rule also covers a majority acquired through a series of asset sales, stock transfers, mergers or consolidations. The transaction history matters alongside the latest purchase agreement.

For a DME change in majority ownership, the thirty-six-month exceptions cover internal restructuring of the supplier’s parent company, a change in the supplier’s business structure with the same owners, and the death of an individual owner. We examine those facts with the ownership and enrollment records when a supplier’s billing identity appears to have outlasted the business that earned it.

Accreditation also does not automatically transfer after a merger, acquisition or sale. The ownership change and the accreditation record each need their own explanation.

The agency’s February 27, 2026 notice imposed a six-month nationwide enrollment moratorium on specified medical supply company types and new locations. The notice connected the moratorium to this ownership rule: a purchase requiring initial enrollment was subject to the same restriction as another new supplier. Buying an enrolled company did not bypass that requirement during the moratorium.

BOC’s Removal and Court-Ordered Restoration

The Board of Certification/Accreditation was absent from the agency’s December 2, 2025 approved-accreditor list and restored to its January 9, 2026 list. The Centers for Medicare & Medicaid Services restored it after a federal court in Maryland ordered it.

For a supplier’s accreditation history, the relevant comparison is between the accreditation date and the agency’s approval at that time.

What Are the Documentation Guidelines for Durable Medical Equipment?

Durable medical equipment documentation includes an order, clinical records supporting the equipment and proof of delivery. Those records connect the claim to the enrolled supplier and its accredited services. The practical question is who actually provided the health care that the paperwork describes.

Regional Home Care, doing business as North Atlantic Medical Services, agreed to an $852,378 settlement announced in December 2014 over allegations that unlicensed personnel provided respiratory care. The whistleblowers’ complaint alleged that an accreditor had already identified the staffing problem:

The complaint alleged that the practices continued. It also alleged that liaisons were told to leave patient-visit signature lines blank for a licensed supervisor to sign later. The survey findings, staff qualifications and patient-visit paperwork describe the same work from different positions. The alleged substitution put patients’ respiratory care in unlicensed hands and billed public programs for it.

The enrollment file can conceal a different separation between the billing business and the work. In its Medicaid Fraud Control Units Fiscal Year 2014 Annual Report, published in 2015, the HHS Office of Inspector General described a civil case involving an excluded equipment company. Another supplier allegedly billed Medicare and Medicaid for that company’s back braces, retained part of the reimbursement and passed the rest along using false invoices. The alleged arrangement put a different business’s name on the bill for the equipment.

For an insider, these cases connect the certificates to the daily business: the person who provided the care, the company that furnished the item, the warning management received and the claim that followed. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.
