Mdwise CPAP question

Hello I am part of the people being moved from healthy Indiana plan mdwise …I have a CPAP rental rn and I'm worried about switching will make it difficult to get either continued my current cpap or new CPAP (not preferred ).I have called my dentist and primary care and they take all 3 options available but my CPAP Dr hasn't answered I left a voicemail last week and another one today (They never seem to have a direct line to a person ) Has anyone had any issues when switching plans while using a CPAP machine? Any advice would be lovely !!
(Anthem , CareSource, MHS are my new options)
