Medical facilities and doctors will sometimes accept a “letter of protection,” which is a document allowing the patient to continue treatment without having to pay for it until a later date. In some cases, people may lack insurance coverage or their PIP benefits have been depleted. In these cases, a medical provider may request a letter of protection. It is essential that the client understand that if the case is not resolved in their favor, the client would still be responsible for paying their medical bills even if there is a letter of protection on file.
