CVA exam - insurance verification questions are way more specific than I expected
Sitting for the CVA in about 3 weeks and the insurance verification sections are hitting harder than the study materials suggested. I've been in medical billing for 4 years so I thought the core concepts would be easy, but the exam-level questions get into specific payer requirements, coordination of benefits rules, and authorization timing that I don't deal with every day in my current role.
The coordination of benefits questions are particularly tricky - specifically the birthday rule, the gender rule, and how Medicare interacts with commercial payers in primary and secondary scenarios. I keep getting about 65% on those practice sets and I'd like to be at 80% before test day. The passing score is reportedly around 70% but I don't want to cut it that close.
I've been doing about 1 hour a day for 5 weeks now. My overall practice score is 74%, which feels okay but my consistency is bad - some days I'll score 82% and other days 66% on similar content. I'm not sure if that's a focus issue or if I haven't truly internalized the material.
Has anyone found a good resource specifically for the COB and Medicare secondary payer rules? The official NAHAM study guide is thin on those sections compared to how much they seem to show up on practice tests.
The CMS MSP manual is publicly available and has the most detailed breakdown of Medicare secondary payer rules I've found. It's a dense read but 2-3 chapters directly map to CVA exam content.
I passed with 76% after 7 weeks of prep. The authorization and eligibility timing questions weren't as bad as I feared - most of them hinge on whether you know the 30, 60, and 90 day windows for specific payer categories.
The inconsistency you're describing usually means you're retrieving from short-term memory rather than actually knowing it. Try spacing your review sessions out more - studying COB rules 3 times over 3 days beats reviewing them 3 times in one sitting.
Birthday rule vs gender rule questions are always scenario-based on the CVA. They'll give you dependent child coverage with two parent plans and ask which is primary - just memorize birthday rule first, then gender rule if birthdays match.
