On March 27, 2017, new rules on evidence became law. Nurse practitioners, physician assistants, and audiologists can now serve as \"acceptable medical sources\" (AMS), while MD/DO\'s and psychologists continue to serve as \"medical consultants.\" In response to the 9th Circuit Court\'s ruling in Garrison v. Colvin (2014), which found that \"credit-as-true\" should be extended to treating physician opinions in matters of social security disability, the SSA rejected this and created rules that made no medical source controlling on any matter reserved to the Commissioner. The new disability listings for neurology and mental health will be reviewed, suggestions will be offered on how to study a new case, what to look for, and how to question professional witnesses during hearings. Finally, cases of disability will be discussed, during the Q/A portion of the presentation.
