I'm a coder and today I got a call from one of the billers saying that they got a letter from Medicaid asking for money back on office visits where patient had any kind of pulmonary diagnosis and had treatments in office for it. They are saying that these are bundled and that they are only going to pay for the $34 neb treatment and not the $138 office visit. As far back as 2011 they are asking for this, has anyone had this yet?
