Our admitting representatives will ask for information to register you at the hospital.  The first four items on the list below are "musts" for everyone. The remaining items may be necessary, depending on your individual situation.

  • Social security number
  • Insurance card
  • Photo identification, such as a driver's license or state photo ID
  • Cash, check, or major credit card to pay for services not covered by insurance
  • Your employer's (or spouse's employer's) name, address, and phone number--if you receive health insurance through that employer
  • Health Plan Referral Authorization--if required by your health insurance carrier
  • Medicare card, plus the date of your spouse's retirement if that applies to you
