H codes are primarily used to report which type of services?

H codes are specifically designated within the coding system to report behavioral health and substance use treatment services. They are utilized to capture a range of services related to emotional and mental health conditions, as well as substance use disorders. This coding is vital for ensuring that providers can document and bill for the various facets of mental health and substance abuse treatment adequately.

The other options relate to different categories of healthcare services and have distinct coding systems associated with them. For instance, physical therapy services are typically reported using specific codes designed for rehabilitation, diagnostic laboratory services involve codes that identify tests and procedures carried out in labs, and emergency medical services have their own set of codes to capture pre-hospital and ambulance services. Each of these areas has unique coding requirements or categorizations, thereby differentiating them from the H codes used for behavioral health and substance abuse services.
