Are you a covered entity?
Basing a county/municipal information security (infosec) and cybersecurity framework on HIPAA is a logical choice, especially if you have one or more covered entities (CE) in your organization.
How do you know if you have or are a CE? If some department or division within your organization is a healthcare provider, a health plan or a healthcare clearinghouse, they are a CE. If you have clinics, doctors, psychologists, clinical social workers, chiropractors, nursing homes or pharmacies, you are a CE [i]. Moreover, many counties have divisions or departments that function as accountable care organizations (ACO), managed care organizations (MCO), healthcare clearinghouses or health maintenance organizations (HMO). These are all common functions, especially within large county governments.
