Documentation and Coding Series: Major Depressive Disorder

In our annual Blue Review readership survey, many of you asked for more articles on coding. In response, our Coding Compliance department has identified resources to help providers accurately code and document patient conditions. Additional articles in the series will run throughout the year. Let us know what you think. Email us!

Depression is the most common behavioral health disorder. It carries a high cost in terms of relationship problems, family suffering and lost work productivity, according to the American Psychiatry Association. Accurately and completely documenting and coding Major Depressive Disorder (MDD) can help our members access needed resources. Below is information from the ICD-10-CM Official Guidelines for Coding and Reporting.

Sample ICD-10-CM Codes
for Single MDD Episode

F32.0

Single episode, mild

F32.1 Single episode, moderate
F32.2 Single episode, severe without psychotic features
F32.3 Single episode, severe with psychotic feature
F32.4 Single episode, in partial remission
F32.5 Single episode, in full remission
F32.8x Other depressive disorders
F32.9 Single episode, unspecified
Sample ICD-10-CM Codes
for Recurrent MDD Episodes
F33.0 Recurrent, mild
F33.1 Recurrent, moderate
F33.2 Recurrent, severe without psychotic features
F33.3 Recurrent, severe with psychotic symptoms
F33.4x Recurrent, in remission
F33.8 Other recurrent depressive disorders
F33.9 Recurrent, unspecified

Coding for MDD
When coding and documenting for MDD, it’s critical to capture the episode and severity with the most accurate diagnosis codes.

Documentation should include:

  • Episode – single or recurrent
  • Severity – mild, moderate, severe without psychotic features or severe with psychotic features
  • Clinical status of the current episode – in partial or full remission

The fourth and fifth characters in the ICD-10-CM codes capture the severity and clinical status of the episode.

F32.9 MDD, single episode, unspecified, is equivalent to Depression Not Otherwise Specified (NOS), Depressive Disorder NOS and Major Depression NOS. This code should rarely be used and only when nothing else, such as the severity or episode, is known about the disorder.

Best Practices

  • Include patient demographics, such as name, date of birth and date of service in all progress notes.
  • Document all information legibly, clearly and concisely.
  • Ensure a credentialed provider signs and dates all documents.
  • Document each diagnosis as having been monitored, evaluated, assessed and/or treated on the date of service.
  • Note complications with an appropriate treatment plan.  
  • Take advantage of the Annual Health Assessment (AHA) or other yearly preventive exam as an opportunity to capture conditions impacting member care.
  • Consider including Social Determinants of Health (SDoH) ICD-10 Z codes on the claims to better track and address the social needs of our members.
