There are no Inpatient charts to code on the CPC-H, it is solely Outpatient Hospital and Ambulatory Surgical Center coding. It is mostly surgical coding, guideline questions, and payment methodology.
I would read up on Medicare's outpatient payment methodology and remember that some HCPCS level II codes are used over CPT codes when it comes to Medicare patients (they do test this knowledge.)
Read the ICD-9-CM guidelines and understand them well, they want to know you know sequencing of coding and the little rules. Such as for outpatient services rule out Diagnosis are NOT coded, only confirmed ones are.
Knowing your modifiers and which ones are allowed for outpatient services is important, there is a condensed list on the front cover of the AMA professional CPT book, but it really is best to have the memorized.
One the questions about payment, guidelines, medical term, and anatomy it is best to be quick as possible so that you have more time on the surgical coding. They will have long winded surgical cases for you to read and abstract. Learning to identify key words is VERY important. Knowing alternative names for things is also important.
Read your CPT book, highlight or underline things that might help you. I cannot stress how important knowing your ICD-9-CM guidelines will help you breeze through some questions and really help you in real world coding, especially if you are trying to get in to inpatient coding.
Practice your surgical coding and know your guidelines and you will do fine.
