In the United States, the DSM serves as the principal authority for psychiatric diagnoses . Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications, so the appearance of a new version has significant practical importance . </P> <P> The DSM - 5 was published on May 18, 2013, superseding the DSM - IV - TR, which was published in 2000 . The development of the new edition began with a conference in 1999 and proceeded with the formation of a Task Force in 2007, which developed and field - tested a variety of new classifications . In most respects, the DSM - 5 is not greatly modified from the DSM - IV - TR; however, some significant differences exist between them . Notable changes in the DSM - 5 include the reconceptualization of Asperger syndrome from a distinct disorder to an autism spectrum disorder; the elimination of subtypes of schizophrenia; the deletion of the "bereavement exclusion" for depressive disorders; the renaming of gender identity disorder to gender dysphoria, along with a revised treatment plan; the inclusion of binge eating disorder as a discrete eating disorder; the renaming and reconceptualization of paraphilias to paraphilic disorders; the removal of the axis system; and the splitting of disorders not otherwise specified into other specified disorders and unspecified disorders . In addition, the DSM - 5 is the first DSM to use an Arabic numeral instead of a Roman numeral in its title, as well as the first "living document" version of a DSM . </P>
