Common Reasons DMEPOS Enrollment Is Denied

A denied Medicare enrollment costs a DME supplier more than time. The application fee is generally not refunded, a new application cannot be filed until appeal rights are used up or lapse, and some denials come with a bar on reapplying for years. Most denials trace back to a handful of causes, and almost all of them are visible before the application is filed.

Is it a rejection or a denial?

The difference matters. Under 42 CFR 424.502, a rejection means the application "was not processed due to incomplete information, or that additional information or corrected information was not received ... in a timely manner." A denial means the supplier "has been determined to be ineligible to receive Medicare billing privileges." A rejected application can usually be corrected and resubmitted; there are no appeal rights, but there is also no adverse determination. A denial is an initial determination with appeal rights, and it can carry consequences.

Common rejection triggers for DMEPOS applications are a missing fee or hardship request (the contractor gives 30 days to pay, then rejects under 424.514(g)), no valid surety bond with the application (the CMS manual tells contractors to reject in that case), and no response to a development request within 30 days.

What are the most common denial grounds for DME suppliers?

From the denial rule, 42 CFR 424.530(a), and the CMS sources that apply it to DMEPOS:

1. No accreditation, or the wrong scope. The Program Integrity Manual tells the contractor to "deny any DMEPOS supplier's enrollment application if the enrollment package does not contain an approved accreditation upon receipt," unless the supplier is exempt. Products on the 855S that the accreditation does not cover are a supplier standard problem too (424.57(c)(22)).
2. Missing state licenses. CMS's fact sheet: "If a DMEPOS supplier violates any supplier standards, like not being appropriately licensed, NPECs may deny enrollment" (MLN905710). The 855S warns that "Failure to attach applicable licensure, certification and/or contracts could result in denial." Each state checked in section 2D needs whatever license it requires; see state license requirements.
3. Supplier standard violations. Non-compliance with any provision of 424.57(c) is its own denial ground (424.530(a)(18)(ii)): a site under 200 square feet, fewer than 30 hours a week, a cell phone as the primary line, a shared location, or insurance below $300,000 or not naming the contractor.
4. A failed site visit. If, "Upon on-site review or other reliable evidence," CMS finds the supplier "Is not operational" or "Otherwise fails to satisfy any Medicare enrollment requirement" (424.530(a)(5)). A locked door during posted hours is the usual story; see the site visit checklist.
5. Owners' fingerprints not submitted. Missing prints from a 5 percent owner lead to denial under 424.530(a)(1) (424.518(d)(2)).
6. A felony in the last 10 years. A federal or state felony conviction of the supplier or any owner, managing employee, officer or director within the preceding 10 years that CMS finds detrimental to Medicare (424.530(a)(3)).
7. Exclusion or debarment of the supplier or of anyone in its ownership or management, including contracted staff (424.530(a)(2)).
8. False or misleading information on the application, which includes leaving out a reportable adverse action or owner (424.530(a)(4)).
9. Medicare debt owed by the supplier or its owners, including debt left behind at a prior company within a year of its termination (424.530(a)(6)).
10. A moratorium. An application for a practice location in an area and supplier type under a temporary moratorium is denied (424.530(a)(10)). The 2026 medical supply company moratorium is the recent example; see the 2026 moratorium.
11. Fee problems. A hardship exception denied with no fee paid within 30 days (424.530(a)(9)), or a fee payment drawn on an account without sufficient funds (424.514(e)).
12. Other program actions. A current Medicaid termination or suspension, or a license revoked or suspended in another state (424.530(a)(14)), and affiliations that pose an undue risk (424.530(a)(13)).

Which denials carry the heaviest consequences?

False information. CMS "may prohibit a prospective provider or supplier from enrolling in Medicare for up to 10 years" if the application was denied because it "submitted false or misleading information on or with (or omitted information from)" the application (424.530(f)). The bar follows the supplier under "any of its current, former, or future names, numerical identifiers or business identities." CMS also reviews every other enrollment the denied supplier is associated with (424.530(d)). The most common route to this outcome is not fraud but an owner's old conviction or a past license action that nobody listed in section 3 or 6B.

How do you respond to a denial?

Read which paragraph of 424.530 the letter cites, because it decides your options. The deadlines in the CMS Program Integrity Manual (chapter 10, section 10.6.18) run from the date of the determination:

• Corrective action plan (CAP). Available only for a denial under 424.530(a)(1), noncompliance. It must be received within 35 calendar days of the date of the initial determination and must contain "verifiable evidence that the provider/supplier is in compliance." A CAP fixes the problem; it does not argue that the denial was wrong.
• Reconsideration. Available for every denial. The regulation allows 60 days from receipt of the notice, with receipt presumed 5 days after the date on the notice (42 CFR 498.22(b)); the manual expresses this as 65 calendar days from the date of the determination. The request must "state the issues, or the findings of fact with which the affected party disagrees, and the reasons for disagreement" (498.22(c)).
• Further appeals. A supplier dissatisfied with the reconsidered determination may request a hearing before an administrative law judge, then Departmental Appeals Board review, then judicial review (498.5(l)). For a moratorium denial, review is limited to whether the moratorium applies to you (498.5(l)(4)).

CAPs and reconsideration requests must be signed by an authorized or delegated official or a properly appointed representative. If a denial rests on the conduct of an owner, manager or official, it "may be reversed" if the supplier ends the relationship and submits proof within 30 days of the denial notice (424.530(c)).

When can you reapply?

Not right away. A denied supplier "cannot submit a new enrollment application" until its appeal rights have lapsed, if it did not appeal, or until it is notified that the determination was upheld, if it did (424.530(b)). A new application means a new fee, and the old one is refunded only in the narrow cases in 424.514(d)(2)(v).

How do we lower the odds of a denial?

The $149 DMEPOS Readiness Review runs the grounds above against your licenses, accreditation scope, location, insurance, bond, ownership chain and adverse history before you file. The Medicare DMEPOS Enrollment Package ($1,295) includes building the 855S so that what it says matches what the contractor will find. If you have already been denied, we can organize the record and prepare the corrective action plan materials for your official to review and sign.
