Guidelines

These are all factors to appropriately interpret and report the procedures and services contained in a particular section. 2. Written general rules and procedures to assist physicians in making a diagnosis and giving treatment. These are set down to change practice styles, lessen unnecessary care, and reduce costs. Depending on the region of the United States, may also be referred to as medical practice parameters, clinical practice guidelines , or clinical protocols .
