I've been a medical coder for 4 years, mostly inpatient, and I'm sitting for the CRC in about 10 weeks. I'm at 90 minutes a day on prep now and plan to bump to 2 hours in the final 3 weeks. The thing I keep hearing is that HCC mapping and RAF score calculation dominate the exam — is that accurate or just what people fixate on?
My plan is to work through the AAPC CRC study guide first, then spend the last 4 weeks on practice exams. I'm hitting around 74% on chapter quizzes, which clears the 70% passing threshold, but I know the real exam is harder than chapter-level questions.
The Medicare Advantage risk adjustment model is basically new to me since I've never worked in that space. HCC categories, the CMS-HCC model versions, V24 versus V28 differences — it's a lot of new material. Anyone have a sense of what percentage of the exam is CMS-HCC versus PACE or commercial risk adjustment?
PACE and commercial risk adjustment were maybe 10–12% combined in my experience. CMS-HCC is the clear majority. Once you understand the logic of hierarchies it's more pattern recognition than memorization.
Your 74% on chapter quizzes is a fine starting point but I'd push to at least 80% before exam day. The real exam uses case studies that require applying multiple concepts at once. The final 3 weeks of practice exams are where most people make their biggest gains.
HCC mapping is definitely the heaviest section — my exam felt like at least 35–40% of questions were directly testing HCC categories or required knowing which conditions map where. The V24 versus V28 transition is being tested now so don't skip that difference.
Four years of inpatient experience helps with coding accuracy but it can also trip you up — outpatient risk adjustment coding has different first-listed versus principal diagnosis rules. Worth explicitly reviewing those differences early so you don't carry inpatient habits into your answers.
