On October 1st, 2020, the 2021 ICD 10 codes update were introduced and became effective. Not all changes are relevant to chiropractors but here is a list of codes that will likely affect you. One of the biggest changes will be for headaches. R51 is being replaced by two codes R51.0 and R51.9. 

R51.0 – Headache with an orthostatic component not elsewhere classified
R51.9 – Headache unspecified.
