At the time of insurance verification, the anticipated patient out-of-pocket amount is calculated based on the scheduled procedure, the insurance plan and deductible, and coinsurance amounts. Final patient responsibility is determined at the time of insurance claim processing. You will be contacted with the anticipated out-of-pocket amount by the Southwest Surgical Center billing representative in writing or by phone approximately one week prior to surgery. This is the amount due when you register on the day of your procedure. Patient cost share amounts not known prior to surgery may be billed after the insurance finalizes your claim.
