Procedure Details
Understanding the Cost
Medicare rate is the amount Medicare pays providers. If you have Medicare, you typically pay 20% of this amount after your deductible.
Private insurance plans negotiate their own rates, typically 130-200% of Medicare. Your out-of-pocket cost depends on your deductible, copay, and coinsurance.
Self-pay/cash prices vary widely. Many providers offer cash discounts of 20-40% off their standard charges. Always ask about cash pricing.
Office vs Hospital: the same procedure often costs less in a doctor's office than a hospital, because hospitals charge a separate facility fee.
