CMS is promoting three National ICD-10 testing Awareness Weeks. Be sure to get involved early, as they have posted a ONE-TIME notice! If you are not ready I suggest you get moving.
To begin with you need to have access to ICD-10 codes, If you don't already have an account with Find-A-Code, Start there! Find-A-Code gives you the information you need to succeed as well as all the crosswalks you need for ICD-10.
