When they are defined by CMS, a Carrier is a contracted company who pays claims for Medicare Professional services or Medicare part B claims. A Fiscal Intermediary is a contracted company who pays claims for Medicare Institutional services or Medicare part A claims. When you are setting up the ANSI enveloping structures you must select the correct qualifiers for the submitter and receiver identification numbers. The correct qualifier for Medicare part B Carriers is usually 27 for ISA 05 and ISA 07. The correct qualifier for Medicare part A Fiscal Intermediaries is usually 28 for ISA 05 and ISA 07. The companion guide for each file receiver should indicate the correct choice of qualifiers. For most commercial payers the qualifiers are ZZ.
