During warmer months, heat from warm air is transferred to the heat exchanger and into the fluid. As it moves through the pipes, the heat is dispersed to the rocks, soil, and groundwater. The pump is reversed during the colder months. Heat energy stored in the relatively warm ground raises the temperature of the fluid. The fluid then transfers this energy to the heat pump, which warms the air inside the building.
While individual states generally govern how long medical records are to be retained â HIPAA. rules require a Medicare Fee-For-Service provider to retain required documentation for six. years from the date of its creation or the date when it last was in effect, whichever is later.
State laws may require a health care provider keep a patient's medical records for a certain period of time. Under PA law, a doctor must keep a patient's medical record for at least 7 years after the last treatment date. The exception is for the medical records of a minor, those records must be kept until 1 year after the minor reaches the age of majority or for 7 years, whichever is longer. Similarly, hospitals must keep medical records for at least 7 years after a patient is discharged from the hospital. Hospital records of minors must be kept until age of majority plus 7 years. In practice, many health care providers keep their medical records longer. And for as long as those records are kept, a patient has a right to see them.
