Pt comes in for depotestosterone every 2-4 weeks. The treatment nurse performs the service. Pt has hypogonadism. Should we code E29.1 and Z79.899 or should the code only be E29.1 which is why the nurse is giving the injection? There is some confusion about the Z79.899 code. We are getting mass amounts of denials asking for chart notes. Any thoughts is greatly appreciated.
