The diagnosis code F43.23, as defined within the International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM), is a crucial element in medical coding and diagnostics. Specifically, F43.23 is used to classify Adjustment Disorder with Mixed Anxiety and Depressed Mood. This code is essential for healthcare professionals, insurance providers, and anyone involved in medical billing and record-keeping. Let’s delve into the details of the F43.23 diagnosis code and what it signifies.
Decoding F43.23: Adjustment Disorder with Mixed Emotional Features
F43.23 is a billable and specific code within the ICD-10-CM system, meaning it’s recognized for reimbursement purposes and pinpoints a precise diagnosis. It falls under the broader category of Adjustment Disorders (F43.2), which are conditions arising from identifiable stressors, leading to clinically significant emotional or behavioral symptoms. F43.23 further specifies a situation where an individual experiences a mix of both anxiety and depressed mood as a reaction to stress.

This diagnosis indicates that the patient is struggling with emotional distress characterized by symptoms of both anxiety and depression, triggered by a stressful life event or circumstance. These symptoms are significant enough to warrant clinical attention but do not meet the full criteria for other specific anxiety or depressive disorders. Terms that are closely related and can be considered approximate synonyms for F43.23 include “Adjustment disorder with mixed anxiety and depressed” and “Adjustment disorder with mixed emotional features.”
Key Aspects of the F43.23 ICD-10-CM Code
- Billable/Specific Code: F43.23 is not a general or unspecified code. It is designed for precise diagnostic coding and is accepted for medical billing and insurance claims when properly documented.
- Effective Date: The F43.23 code was established in 2016, marking its inclusion in the non-draft ICD-10-CM. It has been consistently updated annually, with the 2025 edition becoming effective on October 1, 2024, and remaining unchanged through subsequent updates. This long-standing presence highlights its continued relevance in diagnostic classifications.
- Annotation Back-References: In ICD-10-CM, annotation back-references link F43.23 to other codes that contain related notes such as “Applicable To,” “Code Also,” “Code First,” “Excludes1,” “Excludes2,” “Includes,” “Note,” or “Use Additional” annotations. These references are crucial for coders to ensure comprehensive and accurate coding by considering related diagnostic guidelines and exclusions.
- Diagnostic Related Group (DRG): F43.23 is categorized within Diagnostic Related Groups (MS-DRG v42.0), which are used for determining hospital reimbursement rates based on diagnosis and treatment. This grouping further emphasizes the clinical and financial significance of the F43.23 diagnosis.
- Code History: The stable code history of F43.23, with no changes from 2016 to 2025, indicates its established and consistent definition within the ICD-10-CM system. This stability is important for consistent data collection and analysis in healthcare statistics and epidemiology.
F43.23 in Relation to Other ICD-10 Codes
Understanding F43.23 also requires knowing its place within the broader ICD-10-CM code structure. It is positioned within the F43 category, “Reaction to severe stress, and adjustment disorders,” and is a subcategory of “Adjustment disorders (F43.2).” Adjacent codes provide context:
- F43.2 – Adjustment disorders: The parent category for F43.23.
- F43.21 – Adjustment disorder with depressed mood: Focuses solely on depressive symptoms.
- F43.22 – Adjustment disorder with anxiety: Focuses solely on anxiety symptoms.
- F43.24 – Adjustment disorder with disturbance of conduct: Involves behavioral disturbances.
- F43.25 – Adjustment disorder with mixed disturbance of emotions and conduct: Combines emotional and behavioral symptoms.
- F43.29 – Adjustment disorder with other symptoms: Used when symptoms don’t fit other F43.2 categories.
This placement demonstrates that F43.23 is a specific diagnosis for adjustment disorders where both anxiety and depression are prominent features.
Conclusion: The Importance of F43.23 Diagnosis
The F43.23 diagnosis code is a vital tool in modern medical classification. It allows for the precise categorization of Adjustment Disorder with Mixed Anxiety and Depressed Mood, ensuring accurate record-keeping, appropriate treatment planning, and proper reimbursement processes. For clinicians, coders, and healthcare administrators, a thorough understanding of F43.23 and its context within ICD-10-CM is essential for effective and standardized healthcare delivery. Its continued use and stability in the ICD-10-CM system underscore its importance in diagnosing and managing stress-related emotional disorders.
