Apr. 10, 2021

Depression is the most common mental disorder.

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 Learn more about third-party links.

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 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 preventative exam as an opportunity to capture conditions impacting member care.
