Anthem Blue Cross and Blue Shield (Anthem) is committed to being a valued health care partner in identifying ways to achieve better health outcomes, lower costs and deliver access to a better healthcare experience for consumers.


Effective with dates of service on or after June 1, 2021, medical necessity review of the site of care is required for the following long-acting colony-stimulating factors for oncology indications for Anthem Commercial plan members:  

  • Neulasta® & Neulasta Onpro® (pegfilgrastim)
  • Fulphila® (pegfilgrastim-jmdb)
  • Udenyca® (pegfilgrastim-cbqv)
  • Ziextenzo® (pegfilgrastim-bmez)
  • Nyvepria™ (pegfilgrastim-apgf)


The review will be administered by AIM Specialty Health® (AIM).


AIM will evaluate the clinical information in the request to the CG-MED-083 policy, or Site of Care: Specialty Pharmaceuticals, to determine if the hospital-based outpatient setting is medically necessary for the medication administration. To see the policy and what clinical considerations are taken into account for determination, visit Clinical Criteria page and type Specialty in the search field. You may contact AIM to request a peer-to-peer discussion before or after the determination.


The site of care medical necessity review only applies to administration performed in an outpatient hospital setting. This does not apply to requests for review of medication administration performed in a non-hospital setting or as part of an inpatient stay. Reviews also do not apply when Anthem is the secondary payer.
