New reimbursement policy: Modifier 90: Reference (outside) laboratory and pass-through billing
Effective October 1, 2021, Anthem Blue Cross and Blue Shield does not allow pass-through billing for lab services. Claims appended with Modifier 90 and an office place of service will be denied unless provider, state, federal or CMS contracts and/or requirements indicate otherwise.
Reimbursement will be made directly to the laboratory that performed the clinical diagnostic laboratory test based on 100% of the applicable fee schedule or contracted/negotiated rate.
Modifier 90 is defined as when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified healthcare professional. The procedure may be identified by adding Modifier 90 to the usual procedure number.
