ICD-10 Codes for Depression Are Depressive :-)

ICD-10 codes for depression

Color me difficult, but one of the most frustrating experiences with ICD-9 diagnostic code searches for me has been related to depression. For starters, the EHR system I used at the time had (and still has) a rather primitive search capability, making it unable to produce any relevant results beyond single keyword searches. And, as if that was not enough, a search for depression would return just a couple of results:

  • 779.2 - Cerebral depression, coma, and other abnormal cerebral signs in fetus or newborn
  • V79.0 Screening for depression

It took me some time to realize that I would have a lot more luck searching for depressive, instead of depression. Keep this in mind, as this is still true for ICD-10-CM, for the most part.

Generally speaking, ICD-10 codes for depressive disorders are grouped under several categories:

F32 - Major depressive disorder, single episode

The intent of this category, from what I understand, is to include single episodes of major depression. There are several ICD-10 codes that can be used here, depending on severity, the presence of any associated symptoms, and whether the episode of depression is in partial of full remission (note that F32 is NOT a billable code):

  • F32.0 - Major depressive disorder, single episode, mild
  • F32.1 - Major depressive disorder, single episode, moderate
  • F32.2 - Major depressive disorder, single episode, severe without psychotic features
  • F32.3 - Major depressive disorder, single episode, severe with psychotic features
  • F32.4 - Major depressive disorder, single episode, in partial remission
  • F32.5 - Major depressive disorder, single episode, in full remission
  • F32.8 - Other depressive episodes
  • F32.9 - Major depressive disorder, single episode, unspecified

F33 - Major depressive disorder, recurrent

F33 codes are similar to F32, except that they refer to recurrent episodes of major depression:

  • F33.0 - Major depressive disorder, recurrent, mild
  • F33.1 - Major depressive disorder, recurrent, moderate
  • F33.2 - Major depressive disorder, recurrent severe without psychotic features
  • F33.3 - Major depressive disorder, recurrent, severe with psychotic symptoms
  • F33.4 - Major depressive disorder, recurrent, in remission
  • F33.40 - Major depressive disorder, recurrent, in remission, unspecified
  • F33.41 - Major depressive disorder, recurrent, in partial remission
  • F33.42 - Major depressive disorder, recurrent, in full remission
  • F33.8 - Other recurrent depressive disorders
  • F33.9 - Major depressive disorder, recurrent, unspecified

F32 and F33 codes for depression correspond to 296.xx codes under the ICD-9-CM classification. The exception is ICD-9 code 298.0 - Depressive type psychosis), which in ICD-10 correspondds to F32.3 - Major depressive disorder, single episode, severe with psychotic features, and F33.3 - Major depressive disorder, recurrent, severe with psychotic symptoms.

ICD-9 code 311 (Depressive disorder, not elsewhere classified) translates to ICD-10 code F32.9 (Major depressive disorder, single episode, unspecified).

Other Codes For Depression

  • F03.90 (Unspecified dementia without behavioral disturbance) has two ICD-9 partially equivalent codes:
    • 290.13 - Presenile dementia with depressive features
    • 290.21 - Senile dementia with depressive features
  • F34.1 (Dysthymic disorder) corresponds to ICD-9 code 301.12 (Chronic depressive personality disorder)
  • F43.21(Adjustment disorder with depressed mood) is tranlated from 309.1 (Prolonged depressive reaction)
  • 293.83 (Mood disorder in conditions classified elsewhere) has been expanded to two ICD-10-CM codes:
    • F06.31 - Mood disorder due to known physiological condition with depressive features
    • F06.32 - Mood disorder due to known physiological condition with major depressive-like episode
  • Finally, F25.1 (Schizoaffective disorder, depressive typ) translates 295.70 (Schizoaffective disorder, unspecified)
