  • Is there a way to override the edit and permit payment of both procedures?
  • When is it appropriate to break an NCCI edit with modifier -59?
  • Are there any other edits that affect Medicare reimbursement?
  • Are Medicare Unlikely Edits new?
  • Is the MUE table on the CMS website and now should we interpret it in the context of DOS MUEs?
