DMEPOS Suppliers

Medicare Organization Providers and Subparts: DMEPOS Suppliers

Medicare regulations require that each practice location of a supplier of DMEPOS (if it has more than one) must, by law, be separately enrolled in Medicare and have its own unique Medicare identification number.

• A supplier of DMEPOS enrolls in Medicare through the National Supplier Clearinghouse (NSC) by completing a Form CMS-855S.

• Suppliers of DMEPOS bill Durable Medical Equipment Medicare Administrative Contractors (DME MACs).

• Suppliers of DMEPOS include but are not limited to pharmacies, oxygen suppliers, and outpatient physical therapy agencies. (Any organization that sells equipment or supplies that are billed to Medicare through the DME MAC must be enrolled as a supplier of DMEPOS through the NSC. Sometimes, these are organizations that also furnish services that are covered by Medicare, such as ambulatory surgical centers. In order to be reimbursed for the DME supplies that they sell, they must separately enroll in Medicare as a supplier of DME.)

Medicare Expectations for NPI Assignments for Suppliers of DMEPOS: Each enrolled supplier of DMEPOS that is a covered entity under HIPAA must designate each practice location (if it has more than one) as a subpart and ensure that each subpart obtains its own unique NPI.

Final Notes About NPIs
Enrolled organization health care providers or subparts that bill more than one Medicare contractor: An enrolled organization health care provider or subpart is expected to use a single (the same) NPI when billing more than one Medicare contractor. For example, a physician group practice billing Contractor X and also billing Contractor Y would use a single (the same) NPI to bill both contractors.

Enrolled organization health care providers or subparts that bill more than one type of Medicare contractor: Generally, the type of service being reported on a Medicare claim determines the type of Medicare contractor that processes the claim. Medicare will expect an enrolled organization health care provider or subpart to use a single (the same) NPI when billing more than one type of Medicare contractor. However, in certain situations, Medicare requires that the organization health care provider (or possibly even a subpart) enroll in Medicare as more than one type of provider. For example, an ambulatory surgical center enrolls in Medicare as a certified supplier and bills a Part A/B Medicare Administrative Contractor (A/B MAC).

If the ambulatory surgical center also sells durable medical equipment, it must also enroll in Medicare as a Supplier of DME and bill a DME MAC. This ambulatory surgical center would obtain a single NPI and use it to bill the A/B MAC and the DME MAC. Medicare expects that this ambulatory surgical center would report two different Taxonomies when it applies for its NPI: (1) that of ambulatory health care facility—clinic/center--ambulatory surgical (261QA1903X) and (2) that of suppliers—durable medical equipment & medical supplies (332B00000X) or the appropriate sub-specialization under the 332B00000X specialization.

Enrolled organization health care providers that determine subparts for reasons unrelated to Medicare statutes, regulations or policies:

Consistent with the NPI Final Rule, covered organization health care providers designate subparts for reasons that are not necessarily related to Medicare statutes or regulations. If a Medicare organization health care provider designates as subparts entities other than those that are enrolled Medicare providers, and those subparts obtain their own NPIs and use those NPIs to identify themselves in HIPAA standard transactions with Medicare, those NPIs will not identify enrolled Medicare providers.

Medicare is not required to enroll them. (NPI Final Rule, page 3441: “If an organization health care provider consists of subparts that are identified with their own unique NPIs, a health plan may decide to enroll none, one, or a limited number of them (and to use only the NPIs of the one(s) it enrolls.”))

Medicare uses NPIs to identify health care providers and subparts in HIPAA standard transactions. (NPI Final Rule, page 3469: section 162.412(a): “A health plan must use the NPI of any health care provider (or subpart(s), if applicable) that has been assigned an NPI to identify that health care provider on all standard transactions where that health care provider’s identifier is required.”)

Medicare ensures that the NPIs it receives in HIPAA standard transactions are valid6. Medicare rejects HIPAA standard transactions that contain invalid NPIs. Valid NPIs, however, like the provider identifiers used today, must be “known” to Medicare.

7, nor is it permitted to reimburse providers that are not enrolled in the Medicare program. Medicare returns, with appropriate messages, any HIPAA standard transactions containing valid but unrecognizable NPIs.

Medicare Organization Providers and Subparts

Supplier Groups and Supplier Organizations
Existing Medicare laws and regulations do not establish requirements concerning the assignment of unique identification numbers to supplier groups and supplier organizations for billing purposes.

• Supplier groups and supplier organizations apply for Medicare enrollment by completing a Form CMS-855B.

• Supplier groups and supplier organizations bill Medicare Part B.

• Certain supplier organizations are certified by the States, certified by the Food and Drug Administration (FDA), or must undergo an on-site inspection by the contractor. These requirements vary by type of supplier organization.

• Supplier groups are primarily group practices, such as a group of physicians or other practitioners.

• Supplier organizations include ambulance companies, mammography facilities, and independent diagnostic testing facilities (IDTFs).

Medicare enrolls supplier groups/supplier organizations based on TINs. A supplier group or supplier organization may have multiple locations; however, if each location operates under the same single TIN, Medicare does not separately enroll each location. There are exceptions:

1. When there is more than one Medicare specialty code associated with a single TIN. For instance, if a physician group practice is also an IDTF, it has two different Medicare specialties. The supplier group (the physician group practice) must enroll as a group and the supplier organization (the IDTF) must enroll as a supplier organization. The group practice would complete a Form CMS-855B and the IDTF would complete a Form CMS-855B. Each one would receive its own unique Medicare identification number.

2. If a separate site visit, State certification, or on-site inspection by the contractor or if FDA certification is required for each practice location of that supplier group/supplier organization.

In these above exceptions, Medicare separately enrolls each different Medicare specialty and each separately visited, certified or contractor-inspected practice location.
Medicare Expectations for NPI Assignments for Supplier Groups and Supplier Organizations: To help ensure that Medicare supplier groups and supplier organizations do not experience delays in Medicare claims processing or reimbursement, Medicare encourages each of its enrolled supplier groups and supplier organizations to obtain its own unique NPI. These NPIs have replaced the legacy numbers that are used today in HIPAA standard transactions and in other transactions, such as cost reports. In order for subpart determinations to mirror Medicare enrollment, each enrolled supplier group and supplier organization that is a covered organization health care provider should ensure the following:

• Obtain its own unique NPI.
• Determine if it has any subparts that are themselves enrolled Medicare providers. If there are subparts, ensure that they obtain their own unique NPIs, or obtain the NPIs for them.

EXAMPLE: An enrolled IDTF has four different locations, and each one must be separately inspected by the contractor. All four locations operate under a single TIN. Because each location is separately inspected in order to enroll in Medicare, a total of four unique NPIs should be obtained: one for each location.

Regardless of how an enrolled supplier group or supplier organization that is a covered organization health care provider determines subparts (if any) and obtains NPIs (for itself or for any of its subparts, if they exist), Medicare payments, by law, may be made only to an enrolled supplier group or supplier organization.

Medicare Organization Providers and Subparts

Medicare Organization Providers and Subparts: Certified Providers and Certified Suppliers
Existing Medicare laws and regulations do not establish requirements concerning the assignment of unique identification numbers to Medicare certified providers and certified suppliers for billing purposes.

Certified Providers that bill Medicare Part A (hereinafter referred to as “providers”):

• Providers apply for Medicare enrollment by completing a Form CMS-855A.
• Most providers are surveyed and certified by the States3 prior to being approved as Medicare providers.
2 Clinical laboratory certification is handled by the Food and Drug Administration.
3 Religious non-medical health care institutions are handled differently.
• Providers have in effect an agreement to participate in Medicare.4
• Providers include, but are not limited to: skilled nursing facilities, hospitals5, critical access hospitals, home health agencies, rehabilitation agencies (outpatient physical therapy, speech therapy), comprehensive outpatient rehabilitation facilities, hospices, community mental health centers, religious non-medical health care institutions.
• Providers are assigned CCNs to identify themselves in Medicare claims and other transactions, including cost reports for those providers that are required to file Medicare cost reports.
• In general, each entity that is surveyed and certified by a State is separately enrolled in Medicare and is considered a Medicare provider. (One exception involves home health agency branches. The branches are not separately enrolled Medicare providers.) In many cases, the enrolled provider is not itself a separate legal entity; i.e., it is an entity that is a part of an enrolled provider that is a legal entity and is, for purposes of the NPI Final Rule, considered to be a subpart.

Certified Suppliers, which bill Medicare Part B:• Certified suppliers apply for Medicare enrollment by completing a Form CMS-855A or CMS-855B, depending on the supplier type.
• Certified suppliers include ambulatory surgical centers, portable x-ray suppliers, independent clinical labs (CLIA labs), rural health centers, and federally qualified health centers.
• Certified suppliers are typically surveyed and certified by the States prior to being approved for enrollment as Medicare certified suppliers. (For CLIA labs, each practice location at which lab tests are performed must obtain a separate CLIA Certificate for that location, though there are a few exceptions to this.)
• Certified suppliers may have in effect an agreement to participate in Medicare.
• Certified suppliers are assigned CCNs for purposes of identification within Medicare processes.

However, the contractors assign unique identification numbers to certain certified suppliers for billing purposes. (For CLIA labs, a CLIA number is typically assigned to each practice location for which a CLIA certificate is issued. A CLIA number may not be used to identify a clinical laboratory as a “health care

5 Hospitals bill Medicare Part B for certain types of services.
provider” in HIPAA standard transactions. The CLIA number has no relation to the Medicare PTAN.)

• In many cases, the enrolled certified supplier is not itself a separate legal entity; i.e., it is an entity that is a part of an enrolled provider or certified supplier that is a legal entity and is, for purposes of the NPI Final Rule, considered to be a subpart.

In general, Medicare bases its enrollment of providers and certified suppliers on two main factors: (1) whether a separate State certification or survey is required, and (2) whether a separate provider or certified supplier agreement is needed. (The Taxpayer Identification Number, or TIN, is a consideration as well, though not to the degree of the two main factors.) The CMS regional offices generally make the final determinations on both of these factors; hence, Medicare provider and certified supplier enrollment policy is dictated to a significant degree by the CMS regional offices’ decisions in particular cases.

Medicare Expectations for NPI Assignments for Providers and Certified Suppliers: To help ensure that Medicare providers and certified suppliers do not experience denials of claims or delays in Medicare claims processing or reimbursement, Medicare encourages each of its enrolled providers and certified suppliers to obtain its own unique NPI. These NPIs have replaced the legacy numbers that are used today in HIPAA standard transactions and in other transactions, such as cost reports. In order for subpart determinations to mirror Medicare enrollment, each enrolled provider and certified supplier that is a covered organization health care provider should:

• Obtain its own unique NPI.

• Determine if it has any subparts that are themselves enrolled Medicare providers. If there are subparts, ensure that they obtain their own unique NPIs, or obtain the NPIs for them. Example: An enrolled provider (a hospital) owns 10 home health agencies, all operating under the TIN of the hospital. Because the hospital and each of the 10 home health agencies is separately surveyed and enters into its own provider agreement with Medicare, a total of 11 unique NPIs should be obtained: one for the hospital, and one for each of the 10 home health agencies.

Regardless of how an enrolled provider or certified supplier that is a covered organization health care provider determines subparts (if any) and obtains NPIs (for itself or for any of its subparts, if they exist), Medicare payments, by law, may be made only to an enrolled provider or certified supplier.
