Global Billing
10.2.1 – Global Billing
(Rev. 4473, Issued: 12-6-19; Effective: 3-9-20; Implementation: 3-9-20)
Global billing is acceptable when both the TC and 26 modifier are performed by the
same entity and both the TC and the 26 modifier are furnished within the same Medicare
Physician Fee Schedule (MPFS) payment locality. The TC and 26 may be furnished in
different locations as long as they are furnished within the same MPFS payment locality.
If the global diagnostic test code is billed, report the name, address and NPI of the
location where the technical component was furnished in Items 32 and 32a (or the 837P
electronic claim equivalent). See Pub. 100-04, chapter 1, §80.3.2.1.2 and 80.3.2.1.3 for
more information regarding what is required in Items 32 and 32a.
