The official 2022 ICD-10-CM Guidelines are now available and active! This updated code set is to be used for discharges and patient encounters occurring from October 1, 2021 through September 30, 2022. It’s time to get familiar with what’s new and what has changed.
To help provide a quick reference, we have split the original 115 page document into separate Chapters, each approximately 2-5 pages long and with a focus on specific code groups. By referencing our Chapter list you can more efficiently focus on the specialty you are coding, auditing or teaching.
Be sure to review Section 1.B. General Coding Guidelines for the latest ICD-10-CM general coding guidance.
See what has changed for ICD-10-CM in 2022 in the Tabular Addenda (42 pages).
