Could someone please help me with holter monitor billing. Our practice just recently realized that we have monitors that were not billed. I contacted our company that does the monitors and was given the codes but I'm still confused. I was told that we can bill the 93225 on the day that the monitor is hooked up. Are we allowed to bill this code along with the office visit and an EKG if they are done on the same day as the monitor hook up? I was told to bill 93272 and 93228 once our physician has received the report and read it. I'm confused about these codes are we to bill both codes 93272 and 93228? Are we allowed to bill 93272 to Medicare or just the 93228. I would appreciate all the help that I could get on this matter.
