Hawaii's Service type plans are a type of health insurance plan offered by Hawaii's healthcare providers. The predominant type of Service plan is the Hawaii Medical Service Association (HSA) Health Maintenance Organization (HMO) plan. The HSA HMO plan is a comprehensive health plan that provides coverage for a wide range of medical services such as doctor visits, hospitalizations, lab tests, imaging, emergency services, and prescription drugs. The plan offers preventive care services, such as regular wellness check-ups, immunizations, and screenings, at no out-of-pocket cost. The plan also provides coverage for vision and dental services, as well as mental health and substance abuse services. Depending on the plan, members may also have access to discounted rates for alternative health services such as acupuncture and massage therapy. Other Service plans available in Hawaii include Preferred Provider Organizations (PPO) plans, High Deductible Health Plans (DHP) and Point of Service (POS) plans.
