Check with your insurance company prior to your procedure to assure that you understand your insurance benefits and coverage.  Your colonoscopy is considered to be a screening or routine if have you have no GI symptoms.  If you are experiencing GI symptoms (i.e. abdominal pain, bleeding, diarrhea, constipation, anemia) your colonoscopy is considered to be diagnostic.   If a polyp or tissue is removed during the procedure your colonoscopy may no longer be considered a screening but a surgical procedure.    Information on insurance claims adheres to your medical record.

ATTENTION ALL UNITEDHEALTHCARE SUBSCRIBERS:  If you have a United Health Care Plan you may require an insurance authorization or insurance approval for your colonoscopy.  Your insurance may also direct you to the facility where your policy will cover your procedure regardless of your physician affiliation or your choice of facility.   Call your customer service dept.

Tell the representative you are having a colonoscopy that will be billed using CPT code 45378 or 45380 or 45385 (depending upon findings at the time of your colonoscopy) and ask if your policy requires a UnitedHealthCare insurance prior authorization.  Also tell the representative the facility where your procedure is scheduled.  (Dr. Curran does procedures at Charles River Endoscopy Center which is a free standing ambulatory center or UMass Marlboro Hospital Outpatient Endoscopy Center or Marlboro Hospital Outpatient both hospital based facility.)
