Effective March 1, 2017, outpatient claims for UCare’s State Public Programs (PMAP, MSC+, MinnesotaCare and Special Needs BasicCare (SNBC) or UCare Connect), modifier 59 must be appended instead of L1 to the laboratory service to indicate these are the only services submitted on the claim and are eligible for separate payment. If the 59 modifier is not appended to stand-alone laboratory services, the service line will pay at zero. Modifier 59 must be appended to laboratory services in this situation only. Previously, separately payable laboratory services were identified by the L1 modifier. The L1 modifier is no longer a valid modifier as of January 1, 2017.
