Pricing Transparency

The Centers for Medicare and Medicaid Services (CMS) established guidance which requires hospitals to make available a list of their standard charges online. Hospitals utilize a chargemaster system, which is a list of charges for each service provided to a patient. These charges are the baseline rates for services provided at Hoag Orthopedic Institute and will appear on the patient bill.

The chargemaster rates are updated from time to time to accurately reflect the hospital's expenses to operate.

Standard charges shown in the chargemaster do not necessarily reflect the amount that the patient will pay for the services rendered. Government insurance plans such as Medicare and Medicaid do not pay the chargemaster rates, but rather have their own set rates which hospitals are obligated to accept. Commercial insurance payments are based on rates agreed to by both the insurance carrier and the hospital. Patients without commercial insurance or not covered by a government health care plan should contact the hospital prior to procedure to discuss charges, alternative pricing, and payment terms.
