US Medicare Provider and Supplier Enrollment (42 CFR Part 424 Subpart P) 424.530: Avoid the grounds on which CMS denies enrollment: noncompliance, excluded or debarred persons, felonies within 10 years, false or misleading information, not operational, Medicare debt, payment suspension, missing HHA reserves, unpaid fee, moratoria, prescribing authority loss, revocation under another identity, risky affiliations and other program terminations

CMS may deny enrollment where the provider or supplier is not in compliance with the enrollment requirements and has not submitted a corrective action plan; where the provider, supplier or any owner, managing employee or organisation, officer, director, authorized or delegated official, medical director, supervising physician or other personnel furnishing services payable by a Federal health care program is excluded from Medicare, Medicaid or another Federal health care program or debarred from Federal procurement; where any of them was convicted within the preceding 10 years of a felony CMS determines detrimental to Medicare (crimes against persons, financial crimes, felonies placing the program or beneficiaries at immediate risk, or mandatory-exclusion felonies); where false or misleading information was submitted; where onsite review or other reliable evidence shows the applicant is not operational or otherwise noncompliant; where the applicant or an owner has an existing Medicare debt or left a prior entity with an unpaid debt that CMS finds an undue risk (avoidable by an approved extended repayment schedule or repayment in full); where the applicant or an owning or managing employee or organisation is under a Medicare or Medicaid payment suspension; where an HHA cannot document initial reserve operating funds; where a hardship exception is refused and the fee not paid within 30 days; where a temporary moratorium applies; where a physician's or practitioner's DEA registration or State prescribing authority is suspended, revoked or surrendered; where the applicant is currently revoked under a different name, identifier or business identity and the re-enrollment bar has not expired (judged on common owners and managers, location, type, structure and circumvention evidence); where an affiliation poses an undue risk; or where the applicant is terminated, suspended or barred from a State Medicaid program or other Federal health care program. Denials carry appeal rights and may carry a reapplication bar of up to 10 years for false information or other listed conduct.
