What is the name of your state? Arizona. My mother passed away on November 30, 2006 and I received a final bill from the nursing home where she was living when she died. I believe this bill is overcharging me by over $1200.00. I wrote them a letter disputing the amount they billed me last week, and asked them to send me an itemized bill showing me where this additional $1200.00 plus came from. She was in the ALTEC program for the State of Arizona, so there was a set amount of money which was considered her shared cost for her care each month, and was based on the amount she received from social security. In the meantime, I received a certified letter from them the same day I mailed my letter via regular mail, stating that if I didn't pay the entire bill (the amount I am disputing) by Feb 23, 2007, they will file a lien on my property. My questions are, can they legally file a lien if I am disputing the amount of the final bill? And, are there any penalties or legal options I have if they file the lien for an incorrect amount of money?
