The MHRN diagnosis lists represent the mental health diagnosis codes used by the Mental Health Research Network (MHRN.) The lists are designed to be general-purpose and easy-to-use. Each code is assigned to one category only. ALWAYS REVIEW BEFORE USING to make sure it meets your needs. Some important caveats are listed below.

ICD-9 versus ICD-10: This document pertains to the ICD-10 list. The ICD-9 list in this folder is the final version in use on September 30 2015. If you are interested dementia and/or in continuity in a period spanning the transition, please refer to ICD_9_10_comparisonLists.zip or the expanded dementia package.

For general "any mental health diagnosis" identification, we recommend:

  • Remove codes flagged as "remission" (Remission=1)
  • Remove Injury/poisoning subset and Undetermined injury/poisoning from our list (dx_class not in ('Injury/Poisoning subset', 'Undetermined Injury/Poisoning')
  • If you are interested only in the "core"" diagnoses (see below) and not in Attention Deficit Disorder or Autism Spectrum Disorder, a simple alternative solution is to include anything in the range F0-F48, excepting nicotine disorders (F17.x) and remission codes (F1x.21)

Summary of inclusions:

  1. The following "core" diagnosis classes were vetted collaboratively my MHRN Investigators in ICD-9 and translated and tested in ICD-10:
  • Anxiety Disorder

  • Attention Deficit Disorder

  • Autism Spectrum Disorder

  • Bipolar Spectrum Disorder

  • Dementia *

  • Depressive Disorder

  • Schizophrenia Spectrum Disorder

  • Other Psychosis

  • Substance Abuse Disorder

    * a more complete dementia list including diagnoses outside of the F chapter, is also available in the expanded dementia package.

  1. The following classes were added later on the advice of one or more investigators:
  • Conduct/Disruptive Disorder
  • Eating Disorder
  • Gender Identity Disorder
  • Personality Disorder
  1. The following classes are related to our work on self-harm and suicide attempt. Please refer to README_selfharm before using
  • Self-inflicted Injury/Poisoning
  • Undetermined Injury/Poisoning
  • Suicide Ideation
  • Injury/Poisoning subset
  1. The OTHER category fill in the rest of the F0x-F4x range, with the exception of nicotine-related disorders. From our observations, the bulk of this group observed in the data is affective disorders not categorizable as unipolar or bipolar.
