Range Overview
high priority
The ICD-10 category F30-F39, Mood [affective] disorders, encompasses a range of mental health conditions that primarily affect a person's emotional state. These include depressive disorders, bipolar disorders, and mood disorders due to known physiological conditions. The codes in this range are used to document diagnoses and treatment plans, and are critical for accurate patient records, billing, and research.
Key Usage Points:
- •F30 codes are used for manic episodes, including hypomanic and manic episodes, both with and without psychotic symptoms.
- •F31 codes cover bipolar disorder, from current episodes of mania or depression to remission status.
- •F32 and F33 codes are used for depressive disorders, with F32 for single episodes and F33 for recurrent depression.
- •F34 codes are for persistent mood disorders, including cyclothymia and dysthymia.
- •F39 is an unspecified mood disorder code, used when the mood disorder does not fit into any other categories.
Coding Guidelines
When to Use:
- ✓When a patient presents with symptoms of a mood disorder, such as depression or bipolar disorder.
- ✓When a patient is being treated for a mood disorder.
- ✓When a patient's mood disorder is a significant factor in their current medical condition.
- ✓When a patient has a history of mood disorders that may affect their current treatment.
When NOT to Use:
- ✗When a patient's mood symptoms are better explained by another diagnosis, such as a personality disorder or a substance use disorder.
- ✗When a patient's mood symptoms are a normal reaction to a life event, such as grief.
- ✗When a patient's mood symptoms are due to a general medical condition, such as hypothyroidism, unless the condition is specified in the code.
- ✗When a patient's mood symptoms are due to the direct physiological effects of a substance, such as a drug of abuse or a medication.
Code Exclusions
Always verify exclusions with the latest ICD-10-CM Official Guidelines for Coding and Reporting.
Documentation Requirements
Proper documentation for mood disorders should include the specific type of mood disorder, the current episode or status, and any relevant features or specifiers. It should also include the impact of the mood disorder on the patient's functioning and any relevant history.
Clinical Information:
- •Specific type of mood disorder
- •Current episode or status
- •Relevant features or specifiers
- •Impact on functioning
- •Relevant history
Supporting Evidence:
- •Clinical interview
- •Psychological testing
- •Medical records
- •Collateral information
Good Documentation Example:
Patient diagnosed with Bipolar I Disorder, currently in a manic episode with mixed features. The episode began approximately 2 weeks ago and has significantly impacted the patient's ability to work and maintain social relationships.
Poor Documentation Example:
Patient diagnosed with depression.
Common Documentation Errors:
- âš Not specifying the type of mood disorder
- âš Not documenting the current episode or status
- âš Not including relevant features or specifiers
- âš Not documenting the impact on functioning
