Continue Medicare Supplement and drug coverage if approved for Medicaid?

My 69 year old friend is currently in skilled nursing care (NY) for a combination of issues - legally blind, diabetes, stage 4 kidney failure and dementia. She is non-verbal and generally non-responsive. Prior to her confinement, she had regular Medicare with a Supplement (F) and drug coverage. She also had Medicaid, which covered several hours of home health aide and other services. As she now requires long term care, the nursing home filed and was approved for Medicaid. Her social security is directed to the NH and the personal amount deposited ($50 monthly) into her "house account." I know that not all doctors accept Medicaid and the supplement/RX coverage offered universal blanket coverage. But, now that her situation has changed, should it be continued? The cost is around $350 per month that I have been paying. She has no assets other than Social Security.
