OP here with an update. Mother finally got her first payment yesterday from her LTC insurance company in the amount of $24,000. It took me 6 months of blood sweat and tears to get this payment. I filed many papers, called the company at least twice a week, appealed her denial, filed a complaint with the state insurance department, hired an expensive consultant, hired an attorney, wrote the company CEO and got AARP involved. I don't know what finally did it but the money showed up in her account yesterday. This has been one of the most frustrating experiences in my life. It is now set up from her CCRC to file a claim every month for her expenses, I hope that will got more smoothly.
I bet many families just give up and never get paid by the LTC insurance, I am sure that is what the company hoped I would do.
