Overview of ICD-10-CM 2024 updates

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a medical classification system used in the United States to classify and code diseases and conditions. The Centers for Medicare & Medicaid Services (CMS) maintains and updates the ICD-10-CM code set annually.

For fiscal year 2024, CMS has made a number of changes to the ICD-10-CM code set, including:

  • Adding 395 new codes in 17 different chapters of the code set. Some of the most notable new codes include:

    • Codes for Acinetobacter baumannii sepsis and other diseases caused by this bacteria

    • Codes for desmoid tumors

    • Codes for social determinants of health (SDoH), such as child upbringing and housing

  • Deleting 25 codes that are no longer needed or that have been merged with other codes

  • Revising 22 codes to improve their accuracy or specificity

Some of the key areas of focus for the 2024 ICD-10-CM updates include:

  • COVID-19: CMS has added several new codes to reflect the latest understanding of COVID-19, including codes for long-term COVID-19 and multisystem inflammatory syndrome in children (MIS-C).

  • Social determinants of health: CMS has added a number of new codes to capture SDoH factors that can impact a patient's health. This information can be used to improve patient care and to track population health trends.

  • Mental health: CMS has revised several mental health codes to improve their accuracy and specificity. This will help to ensure that patients with mental health conditions are coded correctly, which is essential for receiving the appropriate care and reimbursement.

Healthcare providers and coders should review the 2024 ICD-10-CM updates carefully to ensure that they are using the correct codes for their patients. CMS has also provided a number of resources to help healthcare providers and coders understand and implement the changes. These resources can be found on the CMS website.
