It's really awfully late in the game to build an ICD-10 trainer program, in my opinion. There are alternatives to AHIMA for the I-10 trainer. My employer sought such training through the American Insitute of Healthcare Compliance (AIHC). I've attached the website below. Although a colleague went through the AHIMA training, I personally believed it to be too long and convoluted for my needs and those of my organization. Therefore, AIHC was a better fit for me. Honestly, if folks have been coding for awhile, the transition should not be impossible. Granted, you may not have the "new codes" memorized like the ICD-9, but that is not the point of the training anyhow.
With AIHC, you have a more modularized format: ICD-10-CM is one part and ICD-10-PCS is the other. I do not know if other organizations do this same thing, but I personally did not have the time between work and formal academic studies to carve out time for a conference, assessments during the conference and then months of training. My AIHC training took long enough and did the same job.
Understand, I am not hocking anyone's product here. I'm just pointing you toward available options.
Unfortunately, there are a vast number of organizations providing I-10 training that does little to help produce people who could train on the subject. The industry calls for trainers in this area and the need exists.
