Legal Question in Credit and Debt Law in Florida

I think this is what you are asking: someone has physical therapy performed on them by AAA, LLC. AAA submits the bill to the patient's insurance company and pays some amount, leaving an amount to be paid to AAA by the patient. At some point (it really doesn't matter when), AAA changes it names from AAA, LLC to The World's Greatest Physical Therapy Company EVER, LLC. If you are asking if the patient is now liable for the unpaid bill to The World's Greatest Physical Therapy Company EVER, LLC. The answer is yes, because AAA changing its name doesn't relieve the patient of his or her debt.
