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.
How long should records be kept? Although states may have different guidelines or laws, The Doctors Company recommends the following: Adult patients, 10 years from the date the patient was last seen. Minor patients, 28 years from the patient's birth. Deceased patients, five years from the date of death. In California, where there is no statutory requirement regarding physician offices, the California Medical Association recommends that medical records be retained indefinitely or for at least 25 years after the patient's last visit.
