What Is an Adjustment Disorder According to the DSM-5-TR?

Experiencing a challenging life event can be overwhelming and cause significant mental distress. An adjustment disorder is a condition that can arise when someone struggles to cope with a situation, such as the loss of a loved one, a career change, or illness. The DSM-5-TR explains that symptoms typically appear within three months of the event and usually last no longer than six months after it has ended.

Facing an adjustment disorder can undoubtedly be a difficult journey. However, it's essential to remind your clients that with proper diagnosis and treatment, many people can experience significant improvement in their symptoms and overall ability to handle stressful life events. With support and time, patients can develop more effective coping mechanisms and often recover fully.

The Different Types of Adjustment Disorders and Their ICD-10 Codes

It can be overwhelming to navigate the different adjustment disorders, each with its distinct ICD-10 code. However, determining the specific code that matches your client's symptoms and presentation is crucial in providing the best care. This code can help identify any current complications and the maladaptive reaction type. Specifiers can also provide additional information about the adjustment disorder, such as whether it's acute or chronic.

Always consider all these factors to understand your client's unique situation. When choosing the correct ICD-10 code, focus on the individual's primary symptoms and presentation. It's vital to evaluate whether anxiety, depression, or both are the most prominent in hindering the person's ability to cope or function normally. Remember, by taking the time to understand your client's needs, you can provide them with the compassionate care they deserve.

  • F43.21 Adjustment Disorder With Depressed Mood: When your client exhibits symptoms of depression, such as sadness, helplessness, hopelessness, low self-esteem, and worthlessness in response to a stressful life event.

  • F43.22 Adjustment Disorder With Anxiety: Your client is experiencing excessive anxiety, including worry, restlessness, and panic attacks due to a stressful life event.

  • F43.23 Adjustment Disorder With Mixed Anxiety and Depressed Mood: When your client experiences symptoms of depression and anxiety as a response to a stressful life event, use this code.

  • F43.24 Adjustment Disorder With Disturbance of Conduct: This code pertains to situations where a person shows symptoms such as defiant behavior, aggression, and destruction of property as primary indicators.

  • F43.25 Adjustment Disorder With Mixed Disturbance of Emotions and Conduct: When emotional distress and defiant behavior symptoms are present.

If you're trying to figure out which adjustment disorder fits your clients' experiences the most, you can ask yourself the following questions:

  • Is the person mainly worried, restless, or irritable (anxiety)?
  • Do they seem sad, hopeless, or pessimistic (depression)?
  • Are symptoms of both anxiety and depression significantly interfering in their life?

Specifiers and Severity

It's important to understand the condition of your clients, and that's why accurately applying relevant specifiers and descriptors is crucial. This includes considering the severity of their condition, which can be classified as mild, moderate, or severe, depending on the level of distress and functional impairment.

For example, if your patient is dealing with anxiety, the F43.2x code is used, and for those experiencing a depressed mood, the appropriate code is F43.1x.If someone is experiencing a combination of anxiety and depressed mood, the F43.0 code should be used.

It's also important to note any time-specific specifiers and consider the condition's duration. If it lasts less than six months, it falls under the acute category, and you should use the .21, .11, or .01 code. If their symptoms have been present for six months or longer, it falls under the chronic category, and you should use the .22, .12, or .02 code.
