Which coding system is used primarily to classify and report hospital inpatient procedures in the United States under ICD-10-PCS?
Answer: ICD-10-PCS codes
ICD-10-PCS (Procedure Coding System) is the US standard for coding inpatient hospital procedures for reimbursement and data reporting.
A facility's EHR allows lab results from an outside reference laboratory to automatically populate the patient's chart without manual entry. This integration relies on which standard?
Answer: HL7 v2 messaging
HL7 v2 messaging is the most widely used standard for transmitting clinical data such as lab results between healthcare systems.
Which concept describes the ability of health systems from different organizations or vendors to exchange and use shared information effectively?
Answer: Interoperability
Interoperability is the ability of different systems to communicate, exchange data, and use information that has been exchanged.
In database design for health information systems, what is the purpose of normalization?
Answer: Organize data to reduce redundancy and improve integrity
Normalization organizes database tables to minimize data redundancy and ensure data dependencies are logical, improving integrity.
Which system architecture model uses a network of independent applications that share data via a central messaging hub rather than direct connections between each pair of systems?
Answer: Hub-and-spoke integration
Hub-and-spoke integration routes all messages through a central hub, reducing the number of individual interfaces needed between systems.
What is the primary function of a Health Information Exchange (HIE)?
Answer: Enable secure sharing of patient health information across organizations
An HIE facilitates the secure, electronic movement of health information among healthcare organizations to improve care coordination.
Which access control model grants system permissions based on a user's job function or organizational role rather than individual identity?
Answer: Role-Based Access Control (RBAC)
RBAC assigns permissions to roles (e.g., coder, nurse, physician) and users inherit permissions by being assigned to a role.
