What are the steps for a physician/practitioner to join a group for Medicare reimbursement?
Both the individual (CMS 855I) and the group (CMS 855B) must first complete the appropriate CMS 855 application form. In addition, the 855R must be submitted at the same time as the 855B and/or 855I for appropriate reassignment of group member payments. If the group is enrolled and the physician/practitioner is already enrolled, and the individual simply wants to join the group, the 855R must be submitted to add the additional reassignment.
