Billing for Interpreters

Good afternoon,

We're looking for feedback as to if other providers are experiencing being asked to 3rd party bill for interpreters joining their H2017 and therapy sessions or if most interpreting agencies are now contracted and doing their own billing to PMAPs? We haven't had a problem with Blue Plus but UCare won't electronically bill without an MDH Roster ID. Does anyone know where to get that ID and how to bill using it?

Thank you for any insight!
