Medicare Advantage Prior Authorization

Blue Cross Blue Shield of Michigan and Blue Care Network require prior authorization for certain benefits. This means we need to review a service to be sure it is medically necessary and appropriate.

If a prior authorization is required for your medical service, your doctor or health care professional must submit the prior authorization request. Once we get the request and supporting medical records, we will begin the review process. 

Do you need prior authorization?

Services summary

If you have a Medicare Plus Blue PPO, BCN Advantage HMO or BCN Advantage HMO-POS plan, our Procedure codes for which providers must request prior authorization (PDF) shows the services that require prior authorization before you receive them.

A prior authorization is not a guarantee of benefits or payment. Please check your member eligibility and benefits and medical policy coverage guidelines.

Clinical review criteria

Blue Cross and BCN use evidence-based clinical standards of care to help determine whether a benefit may be covered under the member’s health plan.

Medical policies follow Medicare Advantage Medical Policy Guidelines to comply with the Centers for Medicare & Medicaid Services (CMS) Policy, National Coverage Determinations (NCDs), and /or Local Coverage Determinations (LCDs). The criteria to determine if a service is medically necessary can be accessed on our Medical Policy Router Search page and in additional criteria.

See the Medicare Coverage Database* for the most current NCD, LCD, Local Coverage Articles (LCAs) and CMS Online Manual System/Transmittals.

Additional criteria

Many procedures have unique criteria to determine coverage. Additional information on specific procedures is available in Authorization Criteria and Preview Questionnaires (PDF)

Inpatient services

Blue Cross and BCN use the following:

  • For acute medical and surgical inpatient requests: Nationally recognized InterQual® medical necessity criteria
  • For post-acute care requests: InterQual criteria for initial screening of requests and CMS criteria to make final determinations
