US Medicare Provider and Supplier Enrollment (42 CFR Part 424 Subpart P) 424.535(a): Avoid the grounds on which CMS revokes enrollment: the denial grounds plus misuse of the billing number, abuse of billing privileges, failure to report changes, failure to document or give access, False Claims Act judgments, Treasury-referred debt, improper prescribing, billing from non-compliant locations and the other listed conduct

CMS may revoke a currently enrolled provider's or supplier's enrollment and any provider or supplier agreement for noncompliance with the enrollment requirements without a corrective action plan (including unpaid user fees and failure to supply requested documentation within 60 days), excluded or debarred persons in the listed roles, detrimental felonies within 10 years, false or misleading information certified as true, not operational or noncompliant on onsite review, screening failures including the application fee, knowingly selling or allowing another to use the billing number, abuse of billing privileges (claims for services that could not have been furnished, such as to deceased beneficiaries, or a pattern or practice of claims failing Medicare requirements judged on denial rates, adverse action history and the type and facts of the noncompliance, with the revocation effective from the earliest or last date of service), failure to report changes under 424.516(d) or (e), 410.33(g)(2) or 424.57(c)(2), failure to maintain or give access to documentation (revocation of up to 1 year per act), HHA initial reserve funds, termination or revocation from Medicaid or another Federal program after appeals are exhausted, loss of DEA or State prescribing authority, a pattern or practice of abusive, unsafe or noncompliant prescribing (judged on diagnoses, impossible visits, overdose-linked dosages, licensing actions, adverse actions, malpractice judgments and other programs' restrictions), a False Claims Act civil judgment within 10 years against the provider or its owners, managing employees, officers or directors, failure to repay a debt referred to the Treasury, revocation under a different identity, an affiliation posing undue risk, billing from a location the provider knew or should have known did not comply, and the further grounds the section lists. Revocation brings a re-enrollment bar of 1 to 10 years (up to 20 years for a second revocation) and termination of the provider agreement.
