Insurance and billing

When you have a surgery at the Stamford ASC, you (or your insurance company) will receive bills for three types of services:

  • your surgeon’s services,
  • the anesthesiology services, and
  • ASC facility services.

The surgeon’s services will be billed by ONS.

Anesthesia services will be billed by Greenwich Anesthesiology. For questions about that bill, call Greenwich Anesthesiology at (203) 863-3390.

You will be billed for the surgery center by Constitution Billing and Financial Services. If you have any questions about fees  prior to your surgery or your billing statement, call (888) 252-7870 x303.
