OXFORD AND AETNA PATIENTS – Does your insurance plan require an in-network referral?
Please check the back of your insurance card and see if there is a box that says In-network Referral Required. If so, you will need to get an insurance referral from an in-network primary care physician, pediatrician or OBGYN.
Please note, if we verify your insurance and find that you need a referral, you will not be able to be seen by the doctor until you get one from an in-network physician.
ONS physicians are “unassigned with Medicare”. This means you will be asked to pay for your visit at checkout. We will submit the claim to Medicare for you, then Medicare will send payment for your visit directly to YOU. The fees we charge are based on the Medicare published fee schedule.
