The four terms on every medical bill — finally explained like a human wrote them. This Maven Innovations mini-course breaks down what a copay actually covers, how coinsurance kicks in after your deductible, what your deductible is really counting toward, and how your out-of-pocket maximum protects you from paying forever. No insurance-speak. No shame for not knowing. Just the plain-English breakdown you should've gotten on day one. Copays. Coinsurance. Deductibles. Out-of-pocket max. Four words, infinite confusion. This course breaks each one down in plain English — so you stop guessing what your medical bill actually means and start understanding it because being a patient shouldn't require a billing degree.
