Sample letter to inform doctors medical license expiration and renewal

Could you give me a sample of a non renewal letter to send to my landlord?

I got my medical records which said I have multiple things wrong with me. The hospital staff didn't inform me about any of them. Are they legally obligated to disclose all information on findings to me at time of service?
