Radiology guidelines fall under the following:  professional, technical, and global.  Professional relates to the services of the physician which includes the supervision of the taking of the x-rays well as the interpretation and report of said x-ray films.  Technical relates to the services of the technologist as well as the use of the equipment, film and other supplies.  Global combines both of the professional and technical guidelines component.  These guidelines provide the template for those who work in the radiology field when documenting the services and for those who code the services provided for billing purposes.
