In order to be a member of OkHIMA (the state association) you must first join AHIMA (the national association).  Each state is considered a Component State Association (CSA).  When you join AHIMA you will set your state designation to Oklahoma and that will automatically join you to OkHIMA.  The fee you pay to AHIMA covers your membership into the CSA.

You can find the membership options for AHIMA at www.ahima.org or by clicking here.
