Most companies don't realise that they are entitled to chase invoices that go back as far as 6 years. It is important to remember that the time limit starts from when your customer last acknowledged owing the debt or made a payment on account against the invoice, not from when the invoice became due.

The golden rule in medical billing is "If it wasn't documented, it wasn't done," meaning every service, diagnosis, and treatment must be thoroughly recorded in the patient's chart to justify billing, ensure compliance, prevent denials, and prove medical necessity, acting as the ultimate proof for payers.
