In this blog post, Valant discusses the ICD-10 codes for depression, ranging from F32.0 to F32.9. It’s important to note coding changes frequently; the new code for 2021 went into effect on October 1, 2020. As of this date, the ICD-10 diagnostic code for major depressive disorder, single episode, unspecified is F32.9.

Other Uses for the ICD-10 F32.9 Code Related to Depression

While major depressive disorder, single episode, unspecified is the typical diagnosis when clinicians bill their services under F32.9, the code can also describe the following:

  • Depression, not otherwise specified (NOS)
  • Depressive disorder, NOS
  • Major depression, NOS

The front portion of this code, F32, describes a single episode of a major depressive disorder and the numeric portion from .1 to .99 includes behavioral, mental, and neurodevelopmental disorders.

Clinical Description and Symptoms of Depression

Depression is a mental health disorder characterized by persistent feelings of melancholy, sadness, or grief. People suffering from depression feel despair and loss of energy to the point it interferes with everyday functioning. The most common symptoms associated with depression include:

  • Feelings of moving in slow motion due to lack of energy
  • Feelings of worthlessness
  • Loss of interest in activities previously enjoyed
  • Prolonged sadness
  • Significant weight gain or loss
  • Sleeping too much or too little


Depression ICD-10 Codes F32.0 to F32.9 – Differentiation

All F32 ICD-10 codes for depression replace the ICD-9 code of 311 for depressive disorder not elsewhere classified. The new coding breaks down the patient’s presentation and symptoms into the following categories:

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

No codes exist from F32.6 to F32.8. As stated above, F32.9 describes major depressive disorder, single episode, unspecified.
