Adjustment disorder is a mental health condition triggered by an identifiable stressor, leading to emotional and behavioral challenges. The ICD-10-CM code F43.23 specifically denotes adjustment disorder with mixed anxiety and depressed mood, a prevalent subtype where individuals experience both anxiety and depression in response to a stressful event. This condition typically emerges within three months of the stressor and can significantly impact daily life, including work, school, or relationships.
The F43.23 code is a critical tool in the U.S. healthcare system, used for accurate diagnosis, billing, and treatment planning. By identifying this specific subtype, clinicians can tailor interventions to address both anxiety and depressive symptoms, ensuring comprehensive care. Unlike international ICD-10 versions, which may use different codes, F43.23 is standardized for U.S. medical billing as of October 2023.
Adjustment disorder with mixed anxiety and depressed mood manifests through a range of symptoms, often tied to the stressor. Common signs include:
These symptoms must be disproportionate to the stressor’s severity and not meet the criteria for other mental health disorders, such as major depressive disorder or generalized anxiety disorder.
According to the DSM-5, adjustment disorder is diagnosed when:
Before diagnosing F43.23, clinicians must differentiate it from other disorders, including:
This careful differentiation ensures accurate diagnosis and effective treatment.
Adjustment disorder is a common mental health condition, with a prevalence rate of approximately 11.5% in the general population, according to a 2017 study by Yaseen Y. Adjustment disorder with mixed anxiety and depressed mood is the most frequent subtype, ranking as the 7th most common psychiatric condition in clinical settings (Maercker et al., 2017). Its high prevalence underscores the importance of clinician awareness and expertise in recognizing and treating this disorder.
Adjustment disorder can affect anyone, but certain stressors increase the likelihood, including:
These stressors can trigger symptoms, particularly in individuals with limited coping mechanisms or support systems.
The concept of adjustment disorder has evolved over time:
This historical context highlights the growing recognition of adjustment disorder as a distinct mental health condition.
Adjustment disorder has six specifiers, each reflecting different symptom presentations:
| ICD-10-CM Code | Specifier | Description |
|---|---|---|
| F43.20 | Unspecified | Maladaptive reactions not fitting other specifiers. |
| F43.21 | With Depressed Mood | Low mood, hopelessness, and tearfulness. |
| F43.22 | With Anxiety | Worry, nervousness, or separation anxiety. |
| F43.23 | With Mixed Anxiety and Depressed Mood | Combination of anxiety and depressive symptoms. |
| F43.24 | With Disturbance of Conduct | Behavioral issues, such as aggression or rule-breaking. |
| F43.25 | With Mixed Disturbance of Emotions and Conduct | Emotional and behavioral symptoms combined. |
The F43.23 specifier is particularly common, reflecting the overlap of anxiety and depression in response to stressors.
Adjustment disorder can stem from various life events, including:
These stressors can vary in intensity but share the potential to disrupt emotional and behavioral stability.
Creating an effective treatment plan for F43.23 focuses on reducing symptoms and building coping skills. Key components include:
Psychotherapy:
Stress Management Techniques:
Support Systems:
Medication (if necessary):

When billing for adjustment disorder with mixed anxiety and depressed mood, consider these best practices:
Accurate billing with F43.23 supports effective treatment planning and improves patient outcomes.
The F43.23 code represents adjustment disorder with mixed anxiety and depressed mood, a condition triggered by a stressor causing emotional and behavioral distress.
Unlike depression or anxiety disorders, adjustment disorder is directly linked to a specific stressor and typically resolves within six months with proper intervention.
Treatments include psychotherapy (e.g., CBT, IPT), stress management techniques, and, in some cases, short-term medication to manage symptoms.
How do you accurately document F43.23 when a patient's symptoms of anxiety and depression are a direct reaction to a recent life event?
For the 2025 ICD-10-CM code F43.23, Adjustment Disorder with Mixed Anxiety and Depressed Mood, your documentation must clearly link the onset of symptoms to an identifiable stressor. Best practices include noting the specific stressor (e.g., job loss, divorce), the timeline (symptoms within three months of the stressor), and the mixed presentation of both anxiety (worry, nervousness) and depressive (low mood, anhedonia) symptoms that are clinically significant but do not meet the criteria for a major depressive or anxiety disorder. Consider implementing AI scribes to automatically capture and structure these crucial details during the patient encounter, ensuring your documentation for F43.23 is always audit-proof and compliant.
What is the best way to differentiate F43.23 from F41.9 (Anxiety Disorder, Unspecified) or F32.9 (Major Depressive Disorder, Single Episode, Unspecified) in clinical notes?
The key to differentiating F43.23 lies in documenting the direct temporal relationship to a specific psychosocial stressor and establishing that the symptoms do not meet the full criteria for another disorder like MDD or GAD. Your notes should specify that the emotional/behavioral symptoms are a maladaptive response to the stressor and would likely remit if the stressor were removed. Explore how AI-powered documentation tools can help parse patient narratives for these specific diagnostic criteria, making it easier to select the most accurate code and avoid common diagnostic ambiguities.
Can I bill F43.23 if the patient denies classic depression but shows clear signs of distress and anxiety after a setback?
Yes, you can still diagnose F43.23, Adjustment Disorder with Mixed Anxiety and Depressed Mood, even with patient denial, provided your clinical assessment supports it. Document the observable signs of distress, such as tearfulness, hopelessness, and worry, alongside the identifiable stressor. Your clinical judgment is key. Using an AI scribe can help you capture the nuanced, verbatim patient language and your objective observations in real-time, providing robust support for your diagnostic conclusion when billing for F43.23.
For F43.23, what are the documentation requirements for billing both psychotherapy and medication management (E/M) codes like 99214 + 90833?
When billing for both services with an F43.23 diagnosis, your documentation must distinctly support both the E/M component (medication management, assessment of physical symptoms) and the psychotherapy add-on code. You must record the time spent on psychotherapy separately and ensure your notes detail the therapeutic intervention, the patient's response, and the plan for ongoing care. The best way to automate documentation is to use an AI scribe that can intelligently separate and format the distinct elements of the visit, simplifying complex billing scenarios.
Do AI scribes replace human scribes for documenting diagnoses like F43.23?
AI scribes are not intended to replace human scribes but rather to augment clinical teams by handling the complex task of medical documentation. For a diagnosis like F43.23, an AI scribe can instantly transcribe the patient encounter, extract relevant details (stressors, symptom timelines, mixed emotional states), and pre-populate the EHR. This frees up both clinicians and human scribes to focus on higher-value, patient-facing tasks. Learn more about how AI scribes can integrate into and enhance your current workflow.
What are the common pitfalls when using the F43.23 code and how can technology help avoid them?
A common pitfall is insufficient documentation linking the symptoms to the stressor, or using F43.23 when a more severe diagnosis like PTSD or Major Depressive Disorder is more appropriate. Another issue is using the code for symptoms that persist more than six months after the stressor has terminated. AI-driven clinical documentation tools can mitigate these risks by prompting for necessary details based on ICD-10 criteria and providing alerts for potential coding inconsistencies, thereby improving diagnostic and billing accuracy.
How specific must the stressor be in the documentation for an F43.23 diagnosis to be considered valid for reimbursement?
The stressor must be an identifiable, significant life event or change; it cannot be a vague or non-specific complaint. Your note should clearly state the nature of the stressor (e.g., "patient lost their job of 10 years," "patient is undergoing a contentious divorce"). The more specific the documentation, the stronger the justification for the F43.23 diagnosis. Consider implementing AI documentation solutions that are designed to capture and highlight these specific data points from the patient conversation, strengthening your claim for reimbursement.
How do AI scribes handle the nuances of patient-reported symptoms for F43.23, especially in telehealth appointments?
Advanced AI scribes are designed to accurately capture and transcribe natural conversation from both in-person and telehealth appointments. They can identify and differentiate between patient-reported symptoms of anxiety (e.g., "I can't stop worrying") and depression (e.g., "I don't enjoy anything anymore"), which is crucial for the "mixed" specifier in F43.23. This ensures that your documentation is rich with the specific details needed for accurate coding, regardless of the consultation format.
What's the best way to track symptom duration for F43.23 to ensure it doesn't evolve into a chronic condition requiring a different code?
Consistently documenting the onset of symptoms relative to the stressor at each visit is the best practice. Your notes should create a clear timeline. An AI scribe can automate this process by tracking mentions of the stressor and symptoms across multiple encounters, making it easy to see if the condition resolves within the expected six-month timeframe post-stressor or if it's evolving into a condition that requires re-evaluation and a different ICD-10 code.
Is there a risk of "upcoding" or "downcoding" with F43.23, and how can I ensure my coding is accurate?
Yes, there is a risk. Downcoding might occur if you use F43.23 when a more severe condition like PTSD is present, while upcoding could happen if the symptoms don't cause clinically significant distress. Accuracy comes from detailed documentation that justifies the code. AI-powered clinical coding assistants can analyze your notes and suggest the most appropriate ICD-10 code based on the documented evidence, reducing compliance risks and ensuring you code with confidence. Explore how these tools can support your clinical decision-making.
Adjustment disorder with mixed anxiety and depressed mood (F43.23) is a common yet treatable mental health condition triggered by significant life stressors. By understanding its symptoms, diagnostic criteria, and treatment options, clinicians can provide targeted care to help clients regain balance. Tools like S10.AI can enhance efficiency in documentation and treatment planning, ensuring better outcomes for those navigating this condition.
