I've finally reviewed all the information about the HCSP reimbursement issue.

From the HCSP letter of October 30, 2017 and the payment of $725.50, in the
absence of divorce documentation, one may conclusively infer that HCSP has
waived its requirement for divorce documentation; accordingly divorce 
documentation has is no longer an issue and should not be pursued.

HCSP wrote "In order to be reimbursed for your assisted living expenses
please provide an itemized billing that lists all charges so that we can
determine what is medically necessary and what isn't." This is a very 
important accounting issue which might save Marion many thousands of dollars.
You should apply to Sholom Home West for the accounting requested by HCSP, 
but be prepared to negotiate both with Sholom Home West and woth HCSP.
A favorable definition of "what is medically necessary" would be of great
financial value.

I advise having Marion sign a new Power of Attorney including authorization 
for fiducial transactions. However, the existing power of attorney is still 
very useful. There is no reason to discard it. I would keep it. The new power 
of attorney will become essential when Marion is no longer able to sign a 
request for reimbursement.

accept:
