Enhancing the Patient Experience

ASCA members work at the forefront of the healthcare community to advance the safety, quality and cost-effectiveness of outpatient surgery.

We know our community is making a difference and that's why we provide the resources, education and advocacy to support this mission.

  • No need to visit a hospital
  • Medicare-certified quality
  • Efficient procedure scheduling and performance
  • Drastically reduced patient copays

Patients Pay Less in
Surgery Centers

ASCs see reimbursement rates per procedure that are roughly half that of hospital outpatient departments (HOPD). This lower cost is passed on to the patient in the form of lower coinsurance.
