How often are revisions to ICD diagnostic codes and guidelines published?

Revisions to ICD diagnostic codes and guidelines are published every year by the World Health Organization (WHO) for ICD-10 and the Centers for Medicare & Medicaid Services (CMS) for ICD-10-CM.

Here's a breakdown:

* ICD-10 (International Statistical Classification of Diseases and Related Health Problems): The WHO publishes revisions every year, typically in the spring.

* ICD-10-CM (Clinical Modification): The CMS publishes revisions to the US-specific version of ICD-10, ICD-10-CM, also every year, with an effective date of October 1st.

It's important to note that these revisions can include:

* New codes: To reflect new diseases, conditions, or procedures.

* Code changes: To update existing codes for clarity or accuracy.

* Guidelines updates: To clarify coding rules and practices.

Healthcare professionals and organizations must stay updated on these revisions to ensure they are using the most current and accurate codes.
