Top 10 mental health diagnoses in 2022

Top 10 mental health diagnoses in 2022

Mental illness impacts millions of people every year. Despite the growing awareness of mental health issues, many patients still face stigma around their experiences and diagnoses.   

According to the National Alliance of Mental Illness (NAMI), about 1 in 5 American adults experience mental illness every year — more than 42 million people. Roughly 1 in 20 American adults experience serious mental illness. A serious mental illness is one that causes significant impairment, interfering with or limiting at least one major life activity.  

It’s crucial to understand the mental health crisis so that we can develop new clinical preventive measures, interventions, devices, and procedures to help those living with psychological conditions or symptoms.  

Definitive Healthcare tracks millions of mental health diagnoses at healthcare facilities. Below, we’ve compiled a list of the top 10 mental health diagnoses by total volume of diagnoses.

What is the #1 most diagnosed mental disorder? 

The top diagnosis is ICD-10 code F411, “generalized anxiety disorder.” It accounted for 8.7% of all mental health diagnoses in 2022. Two of the top ten diagnoses were anxiety disorders, with the second being code F419, anxiety disorder, unspecified. It comprised 7.5% of all mental health diagnoses in 2022.  

Anxiety disorders, mood disorders, and diagnoses related to substance use took up eight of the top 10 spots.  

Three of the top ten spots are mood disorders (F331, F32A, and F329), comprising 3.8%, 2.6%, and 2.4% of all mental health diagnoses of 2022, respectively.  

Lastly, diagnoses related to substance use occupied three spots, including codes F1120 (7.6%), F17210 (2.5%), and F1020 (1.8%).  

Were there more primary mental health diagnoses or secondary diagnoses? 

From the table above, there weren’t any significant differences in primary and secondary mental health diagnoses. The notable exception is opioid dependence, as it accounted for 7.4% of primary diagnoses, but only 2.8% of all secondary diagnoses.  

The difference in primary and secondary codes may possibly indicate that healthcare providers diagnose certain substance use conditions in conjunction with another condition, likely that being the reason for a patient’s initial visit.  In the case of opioids, the patient may be seeing the doctor to treat issues related to nausea, constipation, slowed breathing, or other concerns.  

How did the COVID-19 pandemic impact mental health?  

As a result of the COVID-19 pandemic, mental health worsened across populations. A study published in Brain, Behavior, and Immunity found evidence of a multitude of mental health effects, including:  

  • Decreased psychological well-being across the general public  
  • Patients with COVID-19 displayed high levels of PTSS and higher levels of depression  
  • Higher levels of psychiatric symptoms among healthcare workers   
  • Patients with pre-existing psychiatric symptoms experienced worsened psychiatric symptoms   

Telehealth and mental health   

Although mental health worsened during the pandemic, telehealth also expanded in mental healthcare. Telehealth significantly increases access to mental health services. In particular, telehealth reduces the stress and anxiety around seeking care, improves the accessibility of services for people living with neurological or physical impairments, and provides a private and engaging environment for patients.
