COVID-19 Related ICD-10 CODES:

The COVID-19 outbreak, as well as the pandemic that followed, inspired the Centers for Medicare & Medicaid Services (CMS) to expand access to Medicare’s telehealth services. Through the Coronavirus Preparedness and Response Supplemental Appropriations Act, Medicare beneficiaries are able to receive a greater range of medical services from physicians and other healthcare professionals, through the use of telehealth/telemedical services.

By 2023, in response to the coronavirus pandemic, new COVID-19 related codes have entered the ICD-10 code set. These are used to more uniformly document COVID-19 related diagnoses and procedures. These new codes include:

  • U07.1 (COVID-19, virus identified).
  • U07.2 (COVID-19, virus not identified).

Mental/Behavioral health Related ICD-10 CODES:

Other updates for 2023 include new codes for opioid use disorder. This is largely in response to the opioid epidemic which has impacted numerous individuals, families and communities across the nation. The new ICD-10 codes were added so that it is now easier for healthcare practitioners to properly document the disorder. These new codes include:

  • F11.10 (Opioid abuse, uncomplicated).
  • F11.20 (Opioid dependence, uncomplicated).

Other behavioral health codes were added. Including several new codes that document mental health disorders. These codes include:

  • F45.41 (Pain disorder exclusively related to psychological factors).
  • F41.8 (Other specified anxiety disorders).

Dementia ICD-10 Codes:

In recent years, the number of people diagnosed with dementia has grown significantly across the nation. This growing problem is largely due the growing population of aging baby boomers and their health-related issues. The CMS is likely looking for more detailed information on dementia’s severity and effect on the individual. This would include any associated behavioral disorders that are related to a dementia diagnosis.

In 2023, the ICD-10 classifies dementia (categories F01, F02, and F03) on the basis of the etiology and severity. This severity can be unspecified, mild, moderate or severe. An appropriate selection of the severity level requires the healthcare provider’s clinical judgment.

The appropriate codes should be assigned only on the basis of good provider documentation, unless otherwise instructed by the classification. If the provider’s documentation does not provide information about the severity of the dementia, an appropriate code needs to be assigned a severity description.

ICD-10 codes already exist for dementia, both with and without, signs of behavioral disturbances. However, there is a need for additional detail on other key associated disorders, particularly psychotic disorders, mood disorders and anxiety.

Naturally, it is always important for healthcare professionals to stay up-to-date on the latest ICD-10 codes. This will help to ensure that they submit accurate documentation and billing data for medical services.
