Frequently Asked Questions
How many ambulatory surgery centers are in Maryland?
Maryland has 288 Medicare-certified ambulatory surgery centers (ASCs) across 80 cities. ASCs perform same-day outpatient surgical procedures without an overnight hospital stay.
Does Medicare cover outpatient surgery at ASCs in Maryland?
Yes — Medicare Part B covers approved surgical procedures performed at Medicare-certified ASCs. You typically pay 20% of the Medicare-approved amount after meeting your Part B deductible. All 288 centers listed here are Medicare-certified. Contact individual facilities to confirm which specific procedures they perform and whether your insurance is accepted.
What is the difference between an ASC and a hospital outpatient department?
Ambulatory surgery centers are independent facilities focused exclusively on outpatient surgery. Compared to hospital outpatient departments, ASCs typically have lower patient cost-sharing (due to CMS payment rules), shorter wait times, and a more focused care environment. Studies show ASC patients also report high satisfaction and low complication rates.
