Questions to Ask Your Doctor Prior to Requesting an Estimate

  • What is the exact name of the procedure(s)?
    • Ask the doctor to clearly write out the name of the procedure. Correct spelling is important since many surgery names sound similar.
  • What CPT code(s) will be used for the procedure(s)?
    • CPT codes are the billing codes used by providers for physician services. If you do not have this, please be sure to have the exact name of the procedure.
  • What ICD-9 diagnosis code(s) will be used?
    • The International Classification of Diseases codes identify your health condition and allow health care professionals anywhere in the country to have a shared understanding of conditions.
  • Will you be staying overnight?
    • Does the doctor expect that you will be admitted to the hospital as an inpatient overnight, or that you will be treated on an outpatient basis?
  • In addition, be sure to have the first and last name of the doctor who ordered the procedure. For surgical procedures, please provide the surgeon’s first and last name.
