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.
Instead, the laws in your state regarding record retention would apply. HIPAA rules do require that you apply appropriate administrative, technical, and physical safeguards to protect the privacy of information for as long as you maintain records. There is a 6 year retention period for HIPAA policies and procedures.he Centers for Medicare and Medicaid Services (CMS) requires that patient records for Medicare beneficiaries be retained for a period of 5 years (see 42CFR482.24 (b) [PDF]). Medicaid requirements may vary by state. Additional information about record retention rules [PDF] are available from CMS.
