LMCODER, are you talking about the ICD-10 Proficiency Assessment that all certified folks need to complete to keep active? Or are you talking about the certification exam to get certified in the first place?
The ICD-10 proficiency assessment is the same across the board for everyone. If you've taken a bootcamp live or done the online course, the Q & A are all the same. I did a live bootcamp early in 2014, before the last delay, and my booklet and answers are exactly the same as the 2015 version my co-workers just got. I just bought the assessment a couple weeks ago, and the answers were the same. Easy peasy, breezed right through it.
If you are talking about the certification exam, to become a CPC,etc., then yes, the exam is different for everyone. The test booklet you receive will usually be a different series, with different questions, than the person next to you at the next table taking the same credential. Also, last I checked, the exams will not switch to ICD-10 questions until Jan 2016.
Hope that helps, and best of luck!
