Wiki Bill Modifier 59 to an E/M code

Hello, we are recently getting denial from varies insurance such as Humana denying 99213/99214 with modifier 25 when patient has had a phlebectomy done day(s) prior. For clarification, can you bill modifier 59 to an E/M code? What is the best way to approach this issue?

Modifier 59 is not an E/M modifier it is incorrect. For this scenario please check the document to see if medical records support the separate and significant E/M service other than procedure meaning the doctor has done an assessment and treatment for a separate condition other than a procedure appeal with medical record and appeal cover letter must include the reason for demanding additional pay for E/M

You might need to look at modifier 24 depending on what the patient is being seen for. Seems like there is a 10 day global ( I just looked at 37765), so if it's a related follow up then it's included in the global surgical package. If the visit is unrelated then modifier 24 would be applicable.
