A private plan is a group insurance or employee benefit plan offering basic coverage for prescription drugs. Plans of this type are called private plans because, unlike the public plan, administered by the Régie de l'assurance maladie du Québec, they are offered by private-sector companies.
Private plans are usually available through employment, in the form of group insurance, which an employer may offer to its employees as a fringe benefit. In addition, many professional orders and associations, as well as unions, make such plans available to their members.
Private plans are sometimes called healthcare plans or health insurance plans. Most private plans offer prescription drug coverage along with other services, such as paramedical services or consultations with certain health professionals (chiropractors, physiotherapists, dentists, etc.), but some offer prescription drug coverage only.
Coverage provided may vary from one private plan to another, depending on the agreement entered into between the policyholder Policyholder
