New codes are effective Oct. 1, 2021.

Highly anticipated, the fiscal year 2022 ICD-10-CM codes have been released by the Centers for Disease Control and Prevention (CDC), although still pending are the 2022 Official Coding and Reporting Guidelines which were not included in the package of new codes.

We are still waiting for the release of the 2022 Inpatient Prospective Payment System (IPPS) Final Rule in early August 2021. The CDC release on Wednesday contains 159 new codes, along with the Tabular and Index Addenda. The following is a synopsis of the new codes by chapter.

The Chapter Notes do not include all new codes, but they do provide a highlight from the chapter. There were also many changes made in the coding instructions in the Tabular.  A review of the Tabular Addenda is encouraged to become more familiar with the coding instructions.

The last documents needed for preparation for FY22 are the Official Coding and Reporting Guidelines for 2022 ICD-10-CM and Final Rule for Inpatient Prospective Payment System (IPPS).
