Cervicogenic headache will get its own code. No need for alarm, but this is the month you’re supposed to begin using the new diagnosis codes from the ICD-10 2022 code set. Wait… what? Remember, ICD-10 codes for the following year (2022) go into effect in the October of the previous year (2021).

The order might be different in the final publication, but under M35.0 in ICD-10 2022, the code list will look like this (new codes in bold/italic; revised codes in italic):
