Do the best you can. A month and year are usually acceptable for the dates of your last physician visit. You can even indicate on the health insurance application that you are not 100% sure of the dates. If you are off by a month or two, it will not likely be considered as a fraudulent or deceptive error in the event of a future claims review. The fact that you included this office visit on the application will be recognized as disclosure. If the office visit was for an illness or medical condition that the insurance company wishes to know more about, the medical records they obtain from your physician will provide them with the eact dates of treatment. If you know the name of the doctor that treated you on that visit, you can contact his office for the dates of treatment. In rare cases, a person may have not been to a physician for several years and does not remember the name or address of that physician. In this case, you can eplain this on the application. You might say, The last time I saw a doctor was eight years ago. I do not remember the eact dates or name of the doctor.' Any additional information you can offer, such as the name of the medical clinic or the city, will be helpful. If you can remember why you went to the doctor, include this in your response as well. An insurance company is not likely to be overly concerned about an office visit that was so long ago that you do not recall the details. They are primarily concerned about your more recent visits and any diagnosis of potential health problems that resulted from that recent office visit. If you remember some details about a doctor's office visit, but not the address and phone number of the doctor, try contacting their office for this information. You may also be able to get this information by searching an online provider directory. Most major health insurance companies have an online provider directory that is accessible to the public. Providing address and phone numbers on the application is not typically mandatory for the processing of your application. However, it does assist the insurance company in processing your application more efficiently, which could epedite the approval time.'
