Medicare certified means a healthcare facility or provider has met federal health and safety standards and is approved to treat patients covered by Medicare. If a facility isn’t Medicare certified, Medicare generally won’t pay for services you receive there. This distinction matters every time you choose a hospital, nursing home, home health agency, or other healthcare provider.
How Certification Works
Certification is a formal review process run jointly by state and federal agencies. Each state has a survey agency that inspects healthcare facilities and evaluates whether they comply with standards set by the federal government. After the inspection, the state agency sends its findings and a recommendation to a regional office of the Centers for Medicare & Medicaid Services (CMS), which makes the final decision on whether to approve the facility.
The standards facilities must meet are called Conditions of Participation or Conditions for Coverage. These cover everything from patient rights and infection control to staffing levels and emergency procedures. They exist to protect patients, and they apply to a wide range of facility types: hospitals, skilled nursing facilities, home health agencies, hospices, dialysis centers, ambulatory surgical centers, psychiatric hospitals, critical access hospitals, rural health clinics, and more. A facility that passes inspection is granted Medicare certification and can begin billing Medicare for covered services.
What the Application Process Looks Like
A facility seeking Medicare certification submits an enrollment application (known as the CMS-855 form) that goes through multiple review stages. First, a Medicare Administrative Contractor screens the application, verifying the facility’s information and eligibility. This initial step takes roughly 30 days for online submissions or about 65 days for paper applications.
Next, the state survey agency reviews the application and typically conducts an on-site certification survey, a process that takes approximately 45 days once the agency has a complete packet. Depending on the results, an additional site visit may be required by the Medicare contractor, which can add another 45 days. All told, the process from application to approval can take several months.
Ongoing Inspections and Compliance
Certification isn’t a one-time event. State survey agencies conduct regular inspections to ensure facilities continue meeting federal standards. Nursing homes, for example, are inspected at least once a year. Facilities with poor performance, complaints, or reported incidents may be inspected more frequently.
If a facility falls out of compliance with its Conditions of Participation, CMS has the authority to terminate its Medicare certification. The two main grounds for termination are noncompliance with federal health and safety standards, and violations of provider agreements such as program abuse or quality-related sanctions. Losing certification means the facility can no longer bill Medicare, which for most healthcare providers would be financially devastating and is a strong incentive to maintain standards.
Deemed Status: An Alternative Path
Not every facility goes through a state survey to earn certification. Some facilities get certified by earning accreditation from a private organization that CMS has approved. This is called “deemed status,” meaning the facility is deemed to meet Medicare’s requirements based on the accrediting body’s own inspection. CMS has approved several accrediting organizations for this purpose, including The Joint Commission, DNV Healthcare, the Accreditation Commission for Health Care, and the Community Health Accreditation Partner, among others.
A facility with deemed status is held to standards that meet or exceed Medicare’s federal requirements. From your perspective as a patient, there’s no practical difference between a facility certified through a state survey and one certified through deemed status. Both are Medicare certified and both can bill Medicare for your care.
What Happens at a Non-Certified Facility
If you receive care at a facility that isn’t Medicare certified, Medicare generally will not pay for those services. There are narrow exceptions. In a genuine emergency, Medicare can cover services at a non-participating U.S. hospital, and in some cases at foreign hospitals. But outside of emergencies, using a non-certified facility means you’d likely be responsible for the full cost of your care.
This is why checking certification status matters before choosing a provider, especially for planned procedures, ongoing treatments like dialysis, or long-term care like a nursing home stay. A facility might look professional and well-run but still lack Medicare certification, leaving you without coverage.
How to Verify Certification
The simplest way to check whether a facility is Medicare certified is through Medicare’s Care Compare tool at medicare.gov. You can search by provider type, name, or location to find Medicare-approved hospitals, nursing homes, home health agencies, hospice centers, and other providers near you. The tool also lets you compare quality ratings, inspection results, and staffing data, so it’s useful beyond just confirming certification.
You can also call 1-800-MEDICARE or ask the facility directly. Any Medicare-certified provider should be able to confirm their certification status and provide their Medicare provider number if asked.
Why Certification Matters for Your Care
Medicare certification is more than a billing arrangement. It signals that a facility has been independently inspected and meets a baseline standard of safety and quality. The Conditions of Participation cover areas that directly affect your experience as a patient: whether the facility has adequate staff, how it handles medications, how it prevents infections, and whether it respects your rights to informed consent and privacy.
Certification also creates accountability. Certified facilities face regular inspections, and poor performance can lead to penalties or loss of certification. Non-certified facilities operate outside this oversight structure entirely. When you’re comparing options for a hospital stay, a nursing home for a family member, or a home health agency after surgery, confirming Medicare certification is one of the most basic and important steps you can take.
