Wiki Modifier 25 with labs and x-rays

[dcraven]

Does anyone know where to find the information that if you bill an E/M with a lab and or x-ray you do not need to append the 25?

 

[pamtienter]

Modifier 25 indicates that on the day of a procedure, a significant, separately identifiable E/M service was performed that was above and beyond the usual pre- and post-operative care associated with the procedure or service. X-rays and labs have an "XXX" global day designation which means the global period does not apply, so you should not need a modifier on the E/M if the only other service was an x-ray or lab.
The designations are in the Medicare Physician Fee Schedule in the Global days column.
