Anxiety ICD 10

ICD 10 Anxiety, ICD 10, mental health icd 10

Anxiety ICD 10, types of anxiety disorders and their corresponding ICD-10 codes will be discussed in this article. In addition, we will cover inclusion criteria for each disorder.

We have all felt anxious at some point in our lives. But for many people, anxiety can be highly debilitating. It is estimated that over 30 percent of American adults will experience an anxiety disorder during their lifetime.

Mental health professionals are given the difficult task of evaluating clients and providing an appropriate diagnosis. Fortunately, they do have help.

The International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) categorizes multiple types of ICD 10 anxiety and associated criteria to aid clinicians in the assessment of anxiety disorders.

The codes in the ICD-10 serve multiple purposes. First, they provide specific diagnoses that provide a path towards treatment.

Second, these same codes are used for insurance billing. An accurate diagnosis can have a major impact on developing an effective treatment plan as well as obtaining financial reimbursement. Here is what you need to know about diagnosing anxiety disorders using the ICD-10.

What is the ICD 10 code for Anxiety ?

Anxiety disorders are those where anxiety is the major symptom and can occur in a variety of situations. The following are among the most common anxiety disorders as listed in the ICD-10.

Here is a handy table that lists types of Anxiety ICD 10:

Type of Anxiety Disorder

ICD - 10 Code

Generalized Anxiety Disorder

F 41.1

Panic Disorder

F 41.0

Social Phobia

F 40.1

Specific (Isolated) Phobias

F 40.2


F41.1 Generalized Anxiety Disorder (GAD)

Generalized anxiety disorder is the most often used ICD-10 code for mental health disorders.

It is estimated that 2.7 percent of adults have had GAD in the past year and 5.7 percent will experience it at some point in their lifetime.

Criteria:
  • At least six months with significant tension, worry, and feelings of apprehension, about everyday events and problems.


  • At least one symptom out of the following list of items must be present: palpitations or pounding heart, accelerated heart rate, sweating, and trembling or shaking.


  • Including those symptoms stated above, at least three other symptoms must be present.
These may include:
  • Dry mouth
  • Difficulty breathing
  • Feeling of choking
  • Chest pain or discomfort
  • Nausea or abdominal distress
  • Feeling dizzy
  • Derealisation or depersonalization
  • Fear of losing control, passing out, or dying
  • Hot flushes or cold chills
  • Numbness or tingling sensations


Some clinicians make the mistake of using GAD as a throwaway diagnosis. The thinking goes something like this: If a client has some sort of anxiety but it doesn’t fit into another anxiety disorder then it must be GAD.

While GAD does reflect a more generalized form of anxiety, it does have specific criteria that must be met. It is not the same as F41.9, anxiety disorder unspecified, but is often used like it.

F41.0 Panic Disorder

Panic disorder is one of the scariest anxiety disorders. It has been described as feeling out of control, possibly like a heart attack. An estimated 2.7 percent of U.S. adults had panic disorder in the past year and 4.7 percent experience panic disorder at some time in their lives.

Criteria:
  • Recurrent attacks that are not consistently associated with a specific situation or object, and often occur spontaneously.


  • At least four symptoms must be present, one of which must be an autonomic arousal symptom such as heart palpitations, sweating, trembling or shaking, and dry mouth.


  • Other symptoms may include chest pain, numbness, nausea, stomach problems, dizziness, depersonalization, fear of losing control, and fear of dying.
A panic attack is characterized by all of the following:
  • An episode of intense fear or discomfort
  • Starts abruptly, often without any warning.
  • Escalates to a peak within a few minutes and lasts at least several minutes


The most important consideration with panic disorder is that physical problems must be ruled out. Autonomic arousal, for example, might be caused by health conditions rather than be related to anxiety.

It is not uncommon for many clients to have already seen a doctor about these symptoms before seeking help from a mental health professional.

 

F 40.1 Social Phobia (Social Anxiety Disorder)

To avoid any confusion, you need to know that social phobia is also known as social anxiety disorder. In fact, the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V) refers to it as social anxiety. An estimated 7.1% of U.S. adults had social phobia disorder in the past year and a whopping 12.1 percent of U.S. adults experience social phobia at some time in their lives.

Criteria:
  • One of the following two symptoms must be present for the diagnosis of social phobia. These fears must be exhibited in social situations, such as speaking in public and enduring gatherings such as parties, meetings, and classrooms.


  • Significant fear of being the focus of attention or behaving in a way that will be embarrassing or humiliating.


  • Significant avoidance of being the focus of attention or situations in which there is fear of behaving in an embarrassing or humiliating way.


  • Significant emotional distress is caused by the symptoms or the avoidance of the situation.


  • Symptoms only occur when confronting the anxiety-provoking situation or thinking about it.
At least two symptoms of anxiety (see #2 for GAD above) will be present when confronting the feared situation. In addition, one of the following symptoms is included:
  • Blushing
  • Fear of vomiting
  • Urgency or fear of urination or defecation

 

The key to a correct diagnosis of social phobia is the severity of the disorder. Many people have anxiety in social groups or when they are made the center of attention (e.g., giving a speech in public).

What sets social phobia apart is the lengths someone will go to to avoid those situations. Or, how they feel incapacitated if they find themselves unable to escape.

 

F40.2 Specific (Isolated) Phobias

Specific phobias are the most common of all anxiety disorders. An estimated 12.5 percent of American adults experience specific phobia at some time in their lives. The concept of specific phobia is familiar to most people and may include intense fear of heights, blood, and snakes.

Criteria:
  • A chronic fear of a specific object or situation that is excessive or unreasonable.


  • Exposure to the feared item or situation almost always leads to an immediate anxiety response, which may rise to the level of a panic attack.


  • The person recognizes that the fear is excessive compared to the actual threat posed.


  • The phobic situation is either avoided or endured with intense distress.


  • The avoidance or distress during the feared situation interferes significantly with the person's normal functioning.


  • The fear lasts for at least six months.

 

Like social phobia, the key to a correct diagnosis of a specific phobia is recognizing its severity. Many people have a fear of needle injection, for example, but not everyone will avoid it at any cost.

Individuals with specific phobias experience significant disruption to their lives when confronted with anxiety-provoking stimuli. What is more frustrating, they realize that their fear is often irrational.


Where are Obsessive-Compulsive Disorder (OCD) and Post-Traumatic Stress Disorder (PTSD)?

In the original composition of the ICD-10, OCD and PTSD were indeed considered anxiety disorders. In recent years, however, both disorders have been given their own category. Although anxiety remains a main component of both OCD and PTSD, it has been decided that  there are many additional facets to those disorders that make them unique.

Anxiety is one of the most common and serious problems affecting people worldwide. Proper anxiety ICD-10 diagnosis is integral for both treatment planning and insurance reimbursement.
