HMO plans
Traditional HMO
The Traditional HMO plans have a higher monthly premium with no deductible, low copays, and a lower out of pocket annual maximum, making your total annual expenses more predictable. Hospitalization, radiology, lab tests and most preventive services are also covered at no cost. Generally, specialist services require a referral from your primary care physician (PCP) and you must use the provider’s network unless you have an out-of-area urgent or emergency situation or an approved referral.
Hospital Services DHMO
The Hospital Services DHMO plans offer a lower monthly premium with deductibles only on hospital related services, including emergency room visits, inpatient stays, and outpatient surgery. You pay the full cost of these services up to the deductible then a 20% coinsurance until you reach your out-of-pocket maximum. The out-of-pocket maximum includes the calendar year deductible, copays, and coinsurance. Physician and specialist visits, radiology, lab tests, and prescriptions have a flat copay, without having to meet the deductible. Preventative services are covered at no cost.
Deductible First HDHP
The Deductible First HDHP plans offer the lowest monthly premium and requires a member to meet the calendar year deductible FIRST before ANY plan benefits will be paid, except covered preventive services. Members will pay 100% of the doctor office visits, radiology services, lab tests, prescriptions, hospitalizations, etc., until the calendar year deductible is met. Once the deductible is met, covered medical, hospital, and prescription benefits will be provided for a copay or coinsurance amount. The calendar year out-of-pocket maximum includes calendar year deductibles, copays, and coinsurance.
