README for Diagnosis list(s)
March 29, 2018
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:
- The following "core" diagnosis classes were vetted collaboratively my MHRN Investigators in ICD-9 and translated and tested in ICD-10:
Attention Deficit Disorder
Autism Spectrum Disorder
Bipolar Spectrum Disorder
Schizophrenia Spectrum Disorder
Substance Abuse Disorder
* a more complete dementia list including diagnoses outside of the F chapter, is also available in the expanded dementia package.
- The following classes were added later on the advice of one or more investigators:
- Conduct/Disruptive Disorder
- Eating Disorder
- Gender Identity Disorder
- Personality Disorder
- 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
- 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.
