Key Facts
ICD-10 Range
F30-F39
Overview
This code is used when a mood disorder is clearly present but there is insufficient information to classify it further, or the clinical presentation does not meet full criteria for any specific mood disorder category.
Classification Boundaries
Includes
- Affective psychosis NOS
Excludes1 (coded elsewhere)
- Unspecified mental disorder (F99)
Australian Clinical Context
F39 should be used sparingly in Australian clinical practice. It is acceptable as an initial or provisional code when assessment is ongoing, but clinicians should aim to specify the diagnosis as more information becomes available. For MBS billing purposes, a more specific code is generally preferred.
