What to verify before your procedure — network status, prior authorization, cost estimates, and how to avoid surprise bills.
Insurance coverage for ASC procedures is not automatic. A facility can be in-network while your surgeon is out-of-network — or vice versa. Always confirm both separately.
Doing this before your procedure protects you from unexpected bills after the fact.
You need to verify three things separately: the facility, your surgeon, and the anesthesiologist.
Call your insurer and ask: "Is [facility name] in-network for my plan?" Get the answer in writing if possible.
A facility can be in-network while the surgeon operating there is not. Verify your specific surgeon's network status with your insurer.
Anesthesia is often provided by a separate group. Ask the ASC which anesthesia group they use and confirm their network status independently.
Many insurers require prior authorization (pre-auth) before they'll cover a procedure. If you skip this step, your claim can be denied even if the procedure itself is covered.
1.Call the member services number on your insurance card and ask whether your specific procedure (use the CPT code your surgeon provides) requires prior authorization.
2.If it does, your surgeon's office typically handles the authorization request. Confirm they have submitted it and received approval before your procedure date.
3.Get the authorization number and keep it. If there's a billing dispute later, you'll need it.
Note: Prior authorization is not a guarantee of payment. The insurer can still deny the claim if the procedure is performed differently than authorized, or if other coverage conditions aren't met.
Medicare Part B covers outpatient surgery at Medicare-certified ASCs. The facility fee is reimbursed at the ASC rate, which is generally lower than the hospital outpatient rate.
Medigap / Supplement plans often cover the 20% coinsurance. Check your specific plan to confirm.
Medicaid covers ASC procedures in most states, but coverage rules vary significantly. The ASC must be enrolled as a Medicaid provider in your state.
Coverage varies significantly by plan. ASCs are typically covered as outpatient facilities, but your cost share depends on your specific plan's deductible, copay, and coinsurance structure.
ASCs often have self-pay rates that are significantly lower than hospital rates for the same procedure. Many facilities will negotiate a bundled rate that includes the facility fee, surgeon, and anesthesia.
As of January 2022, the No Surprises Act protects patients from unexpected out-of-network bills in most situations. If you receive care at an in-network facility, out-of-network providers at that facility (such as an anesthesiologist) generally cannot bill you more than your in-network cost share.
The No Surprises Act has exceptions and limitations. It does not apply to ground ambulance services or to situations where you voluntarily choose out-of-network care and sign a consent form.
1.Is this ASC in-network with my insurance plan?
2.Is my surgeon in-network? What about the anesthesia group?
3.Does this procedure require prior authorization, and has it been submitted?
4.Can you provide a good-faith cost estimate in writing?
5.What are my expected out-of-pocket costs after insurance?
6.What happens if additional procedures are needed during surgery?
7.Who do I call if I receive an unexpected bill after the procedure?
