The Commerce Department’s Bureau of Economic Analysis has created an updated report specifying the amount of money spent to treat different medical conditions across the United States. Mental disorders are the most expensive conditions as a group according to the findings, with annual spending at $201 billion as of 2013.

The spending included in the report covered inpatient psychiatric treatments for the first time as well as outpatient services. An earlier version of the report, with data gathered from 1996 to 2005, included only outpatient treatments for mental health in its analysis.

This report, along with its earlier version, has also brought new light to the field of medical spending by ensuring that it does not double count the funds used to treat multiple health conditions simultaneously.
