Hello and Thank you for using JustAnswer Health for your question.
May I clarify your question please - are you speaking of medicare and medicaid supervisory visits for home health as in RN's supervising the nursing assistants? Are you doing audits for a home health care agency?
For example, Medicaid home health (in Alabama as of 2007) supervisory visits by an RN must be done at least every 60 days when services are provided by an LPN, HHA, or orderly. The services may be provided on a part-time basis only and must be ordered by the attending physician. The RN who is responsible for the care of the patient must supervise the service. Reference: http://www.medicaid.alabama.gov/documents/Billing/5-G_Manuals/5G-2_Provider.Manual_Jan.2007/Jan07_17.pdf
Similar guidelines are found with a more recent date (2010) as well for the state of Wisconsin: RN supervisory visits must be 'no less than every 60 days' Ref: http://www.dhs.wisconsin.gov/ltcare/Partners/infoseries/tamemo10-12.pdf
I looked for specifications for Medicare and Medicaid from a Federal source, but so far have not found it, although the states of course must follow the federal guidelines.
I have worked in home health in the past as a Psychiatric Nurse, and have never performed anything but every 60 day RN supervisory visits, so very likely the requirement is the same for both Medicare and Medicaid.
I hope this answers your question. Please reply to this post if you need further clarification or I have not touched on what you were trying to understand so that I or another expert may assist you until you are satisfied with your answer.
