drug administration services and E/M visits billed on the same day of service as follows:

Carriers must advise physicians that CPT code 99211 cannot be paid if it is billed with a drug administration service such as a chemotherapy or non-chemotherapy drug infusion service (effective January 1, 2004). This drug administration policy was expanded in the Physician Fee Schedule Final Rule, November 14, 2004, to also include a therapeutic or diagnostic injection code (effective January 1, 2005). Therefore, when a medically necessary, significant, and separately identifiable E/M service (which meets a higher complexity level than CPT code 99211) is performed, in addition to one of these drug administration services, the appropriate E/M CPT code should be reported with modifier -25. Documentation should support the level of E/M service billed. For an E/M service provided on the same day, a different diagnosis is not required.
