How long after a bill is submitted can it be presented for payment?
Question Details: My grandfather died 4 years ago and I am the executor of his estate. I received notice from a skilled nursing facility that he apparently received treatment there almost 6 years ago and the co-payment was never paid. The bill is several thousand dollars. However, upon calling my grandfather's insurance company to confirm the dates, they informed me that they never paid or even received a bill from the facility for the dates in question. Presumably, the facility made some mistake and apparently my understanding is that at this late date they cannot request payment anymore. Assuming they can show evidence that my grandfather did in fact stay there, can they still request payment for the co-payment on a bill they never submitted.
