Healthcare Service Providers
‘‘Healthcare provider” 45 CFR 160.103: Healthcare provider means a provider of services (as defined in section 1861(u) of the Act, 42 U.S.C. 1395x (u)), a provider of medical or health services (as defined in section 1861(s) of the Act, 42 U.S.C. 1395x(s)), and any other person or organization who furnishes, bills, or is paid for healthcare in the normal course of business. Examples of healthcare providers included in this definition are: Physicians and other practitioners; hospitals and other institutional providers; suppliers of durable medical equipment, supplies related to healthcare, prosthetics, and orthotics; pharmacies and pharmacists; and group practices. There are individuals and organizations that furnish atypical or nontraditional services that are indirectly healthcare-related, such as taxi, home and vehicle modifications, habilitation, and respite services. These types of services are discussed in the Transactions Rule at 65 FR 50315. As stated in that Rule, many of these services do not qualify as healthcare services because the services do not fall within our definition of ‘‘healthcare.’’ An individual or organization must determine if it provides any services that fall within our definition of ‘‘healthcare’’ at § 160.103. If it does provide those services, it is considered a healthcare provider and would be eligible for an NPI. If it does not, and does not provide other services or supplies that bring it within the definition of ‘‘healthcare provider,’’ it would not be a healthcare provider under HIPAA, and would not be eligible to receive an NPI.
