Q: How will Hartford HealthCare know in which health plan I participate?

A: Please present your current health plan identification card when you register for inpatient or outpatient services at your appointment.

Q: What is the difference between an HMO and a PPO?

A: Health Maintenance Organizations (HMOs) require a patient to select a Primary Care Physician to coordinate his or her care. Most HMOs provide care through a network of hospitals, doctors and other medical professionals, that as a patient, you must use to be covered for that service. Preferred Provider Organizations (PPOs) provide care through a network of hospitals, doctors and other medical professionals. When patients utilize health care providers within the network, they receive a higher benefit and pay less money out of their pocket. Services received by a non-participating hospital or doctor may still be covered, but often at a reduced benefit level.

Q: What does "in-network" and "out-of-network" mean?

A: If you receive your health care services from a hospital, physician or other health care provider that participates in your health plan, they are often referred to as "in-network." Hospitals, physicians or other health care providers who do not participate in your health plan may be referred to as "out-of-network." For more common insurance terms, click here.
