"Published by the American Psychiatric Association (APA), the Diagnostic and Statistical Manual of Mental Disorders (DSM) creates a standard for diagnosis amongst mental health professionals. The current version is the DSM-IV-TR, but the APA is currently working on the DSM-V slated for publication in May 2013. But what does the DSM have to do with gender?
"Currently, the DSM records Gender Identity Disorder (GID) as the diagnosis for people along the trans* spectrum, listing the following criteria: long-standing and strong identification with another gender, long-standing disquiet about the sex assigned or a sense of incongruity in the gender-assigned role of that sex, the diagnosis is not made if the individual also has physical intersex characteristics, and significant clinical discomfort or impairment at work, social situations, or other important life areas. Most doctors and insurance companies are only willing to treat or to pay for physical transition (hormones and surgery) when presented with this concrete diagnosis."
