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.
For example, under HIPAA, dentists are required to maintain records of disclosures of information for at least six years. No doubt many dentists have found it expedient to keep all records indefinitely rather than to establish a records retention policy. Old and dusty records arenât generally a source of liability. This is because negligence claims associated with treatment provided are usually subject to specific statutes of limitation.
