Beginning with dates of service on or after January 1, 2021, we will update the policy language to indicate modifier 90 will not allow reimbursement when reported in a place of service office (11). Modifier 90 is defined as Reference (Outside) Laboratory: When laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number.
