I send a certified letter to both the patient and CDPHE and explain to the patient that they are responsible for changing their caregiver status within 10 days of receiving the letter. I also provide a link to the new caregiver form so they have no excuses.

I check the tracking online and make a copy of the confirmation that both parties have received my letters and staple that to the patient's paperwork.

I feel this covers myself. I can't make a patient change their caregiver status and that's why I send a letter to CDPHE also.
