The exact amount of time that it will take to complete the provider enrollment process ultimately depends on the payor(s) that you are working with. With that said, though, it is important to understand and prepare for the fact that the enrollment process can often take quite a long time. With government payors such as Medicare or Medicaid, for example, enrolling a new provider can sometimes take upwards of six months. With this being the case, it's essential to begin the enrollment process as soon as possible.
