What to ask before your procedure
A general checklist for any outpatient surgery center, not advice about this one. Medicare also publishes guides on medicare.gov.
- Does the center do the procedure your doctor recommended, and how many of them does it do each year?
- Is your surgeon allowed to operate there? Who gives the anesthesia (an anesthesiologist or a nurse anesthetist)?
- Does the center accept your insurance or Medicare? Ask for the expected cost, including the surgeon, anesthesia and any tests, in writing.
- What should you do before the procedure (food, drink, medicines), and do you need someone to drive you home?
- Which hospital does the center send patients to if there is a problem, and how far away is it?
- Who do you call after you get home if you have pain, bleeding, fever or other problems, including at night?
- Is the center accredited, and can you see its most recent state or Medicare inspection?
- Are there staff or interpreters who speak your language?
