A large managed care company has introduced a high-deductible health maintenance organization plan for Golden State employers.

Aetna Inc., Hartford, will be running Aetna HealthFund HMO plans for employers with 50 or more employees starting in January 2007.

The HMO plan pays 100% of the cost of preventive care and many other routine, in-network services.

Program members can use a health reimbursement arrangement to cover most of the cost of care that is subject to the plan’s deductible, such as inpatient hospitalization.

Deductibles range from $500 to $1,500 for individuals and $1,000 to $3,000 for families.

HRA amounts can range from $250 to $1,000 for single individuals and $500 to $2,000 for families, Aetna says.
