Definition of Modifier 57
There are certain modifiers which should be used only with E&M CPT codes, for example 24, 25 and 27. Even Modifier 57 should be used along with E&M codes (99201-99499).

Modifier 57 is totally different from modifier 25. You can see the definition of both of them above, which will clear most of your doubts. When an E&M service prompts the physician to go for a major procedure or surgery within 90 days’ global period and within 24 hours of E&M service, modifier 57 needs to be appended along with the E&M service cpt code.

There are procedures which has 0, 10 and 90 days of global period.

Since, it is 90 days’ global period Medicare allows to append modifier 57 with
