The records the doctor makes for his treatments of his patient, belong to the patient. This matter is poorly understood by the medical profession. You have an absolute right to see your records and to have copies of them. If your doctor has written poor records, you have a right to ask for clarification. Many doctors in their arrogance feel they do not have to write records that can be read, but Medicare and Medicaid both require complete, legible records. That means they must be readable. You may find, especially in a state like Texas, that doctors "refuse" to allow patients to see their own records. In that case, you may need to go to a lawyer who can demand the records. By definition a doctor is the custodian of the patient's records, he is not the owner.
Think of your records in tbis way: When a doctor performs any treatment on you, he records his treatment so you, the patient, may be able to inform your next doctor/hospital what has been done to you in the past. For instance, when you buy insurance from a broker, that broker supplies you with a written copy of what your insurance promises. If you ask a contractor to plan an addition to your home, he makes a drawing of his proposal, and often specifications. This is not so he knows what to do next, but so you have a written record of what he proposes to do, and by the way, so the building department of your city also knows what he plans to do. Making a record is part of the job you pay for. It is not separate.
