I just passed the test for my CPC in October and had recently passed an ICD-10 proficiency test through AHIMA that was required by my employer. AAPC will not honor my test results and give credit for the proficiency test. I am not happy. My question, is it worth purchasing the ICD-10 practice tests or do you think it is a waste of money? I cannot believe how expensive it is to be in this industry. Just venting.
