How to submit prior authorization requests for inpatient admissions involving elective surgeries

When submitting a prior authorization request for a Blue Cross Blue Shield of Michigan commercial member admitted for an inpatient elective surgical procedure, do the following:

  • Enter only the primary procedure code for the surgery. If you enter additional procedure codes, the claim may not be paid.
  • Include the supporting diagnosis code.

Blue Cross utilization management nurses who review the request only look at primary procedure and supporting diagnosis codes to determine whether the surgery meets the medical necessity criteria for an inpatient setting.

Be sure to check the member’s benefits and eligibility for the surgery and any other planned procedures.

Note: For inpatient medical admissions that don’t involve surgeries, enter procedure code *99222 for the admission.
