Prior Authorization Admission Request

A Prior Authorization Admission request is the process of notifying Blue Cross Blue Shield of Wyoming (BCBSWY) of an inpatient stay. The participating Provider or Member must notify BCBSWY of ALL inpatient stays including emergency admissions. When a patient is transferred from one facility to another, the Provider of the receiving facility should notify BCBSWY. 

Our policies begin with the following prefixes:

  • QWY
  • YWY
  • ZRW
  • ZSD
  • ZSF
  • ZSH
  • ZSK
  • ZSM
  • ZSP
  • ZYW
  • R (FEP)

For all other prefixes, please call 1-800-676-2583 to find the Blue Cross Blue Shield Plan you will need to contact for Prior Authorization Admission requests.
