Here’s what you need to know about ICD 10 codes for anxiety disorders.
GAD: Symptoms and Prevalence
GAD affects about 3 percent of the U.S. population each year, making it a frequently-diagnosed mental health concern. If you treat patients for anxiety, chances are you’ll be using the F41.1 code regularly.
GAD causes feelings of worry, nervousness, fear, or dread that last six months or more. It may cause a patient to worry excessively over many different problems, or to worry without an apparent cause. Physical symptoms like disrupted sleep, sweating, or feeling short of breath may be present as well. Clients who suffer from GAD often experience worry that is out of proportion to the threats they actually face in day-to-day life. They may be unable to control their worry, and may anticipate worst-case scenarios even when that conclusion is not warranted.
While the exact cause of GAD is unknown, it’s most likely a influenced by various factors including brain chemistry, genetics, personality, trauma history, family background, and other social or lifestyle factors.
Symptom Criteria for Generalized Anxiety Disorder F41.1
To meet the criteria for a diagnosis of generalized anxiety disorder, a patient should have at least three of the following symptoms along with their fear and worry:
- Feeling easily fatigued
- Feelings of restlessness or being on edge
- Irritability
