Failed COC exam twice — what am I missing in my prep? — Forums

So I've now failed the COC exam twice and I'm honestly starting to question everything. First attempt I scored a 68, second time a 71 — so I'm getting closer but that 75 passing score feels like a wall I can't break through. I've been in outpatient coding for about four years so it's not like I'm a complete newbie, but the exam just keeps catching me on E/M leveling and the surgical package rules.

I've been using the AAPC study guide and doing random practice questions online, but I don't think my prep has been systematic enough. Someone in my local chapter mentioned a COC practice test that actually mirrors the real exam format — has anyone used something like that? I need timed, full-length simulations, not just random question banks.

My third attempt is scheduled for August and I really can't fail again — my employer is covering the fee but I get the sense patience is running thin. Any study guide recommendations or exam tips from people who've passed on a third attempt would mean a lot right now.

Honestly the AAPC study guide alone wasn't enough for me either. I supplemented with a COC practice test from a third-party vendor that had detailed rationale for every wrong answer. That's where I learned the most — not from getting questions right, but from understanding WHY I got them wrong. Also block out time to review the surgery guidelines in CPT front matter. Most people skip that and it costs them.

I passed on my third attempt too, so don't give up. The thing that finally clicked for me was drilling E/M with actual op reports instead of textbook examples. I spent about 6 weeks doing 90 minutes every morning before work — just coding real-world scenarios. Also, the COC specifically loves testing global surgery periods and bundling, so make sure you know your modifiers cold. -59, -79, -78 especially.

71 is actually really close — you're not starting from zero here. Focus your last few weeks on high-yield stuff: E/M, surgical package, and Medicare bundling rules. Don't try to relearn everything. Targeted review plus timed practice is what gets you over the line.
