I work at a Pulmonary office in Pennsylvania and we are having issues with Highmark denying 94060 when we bill it with 94726 and 94729 on the same date of service with modifier 26. They are saying maximum units met. Cannot bill patient. We have tried calling Highmark several times and no one can giveus any guidance as to why they wont pay it. Even if this is the first time the patient has had this test done in the year. I am totally lost. Are there any CCI edits that we are missing? Would be grateful for any help please. Thank you.
