I dont think they will ask you that but:
capitation: when insurance company x, pays a doctor a set fee for seeing patients with this insurance company, no matter the amount of patients; instead of paying per patient, which is the more regular way of paying.
HMO: patients with this type of insurance have more restriction to see doctors, and usually can only see doctors contracted within this insurance network.
PPO: more flexibility to see any doctor, but patients may have to pay decustibles(amount out of the patient pocket) every year or for certain procedures.
HIPAA: a goverment law that regulates how doctors and staff manage patient information, basically, this information is confidential and can only be disclose to people realated with this patient medical care or to people that the patient has authorized to receive.
Hope that helps, 😀
