Coding notes for F32.1

  • Single episode only - a prior major depressive episode moves the client to F33.1
  • Moderate severity sits between F32.0 (mild) and F32.2 (severe without psychotic features)
  • Update the code when severity or remission status changes rather than carrying the intake code forward

What to document for medical necessity

Payers look for a record that supports the diagnosis and the level of care. For depressive disorders that usually means:

  • The symptoms that support the diagnosis and how long they have been present
  • The current severity (mild, moderate, severe) and how you arrived at it - a scored measure such as the PHQ-9 helps
  • Whether this is a first episode or a recurrence, since that decides F32 versus F33
  • Functional impairment at work, school, home, or in relationships
  • Risk assessment, including suicidal ideation, at intake and when it changes
  • Treatment plan goals tied to the depressive symptoms you are treating

Does F32.1 need a PHQ-9 score?

ICD-10-CM does not require a specific measure. A scored tool like the PHQ-9 is still a simple way to show how you arrived at moderate severity, and many payers look for objective measures in the record.
