CCS System Architecture and Design 3 — Questions and Answers
Question 1: Which coding system is used primarily to classify and report hospital inpatient procedures in the United States under ICD-10-PCS?
- CPT codes
- HCPCS Level II codes
- ICD-10-PCS codes (Correct answer)
- CDT codes
Correct 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.
Question 2: 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?
- HL7 v2 messaging (Correct answer)
- ICD-10-CM
- ANSI X12 270/271
- SNOMED CT
Correct answer: HL7 v2 messaging
HL7 v2 messaging is the most widely used standard for transmitting clinical data such as lab results between healthcare systems.
Question 3: Which concept describes the ability of health systems from different organizations or vendors to exchange and use shared information effectively?
- Redundancy
- Interoperability (Correct answer)
- Scalability
- Normalization
Correct answer: Interoperability
Interoperability is the ability of different systems to communicate, exchange data, and use information that has been exchanged.
Question 4: In database design for health information systems, what is the purpose of normalization?
- Increase data redundancy for backup purposes
- Encrypt sensitive patient fields
- Organize data to reduce redundancy and improve integrity (Correct answer)
- Assign unique identifiers to all records
Correct 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.
Question 5: 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?
- Point-to-point integration
- Hub-and-spoke integration (Correct answer)
- Monolithic architecture
- Hierarchical database model
Correct 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.
Question 6: What is the primary function of a Health Information Exchange (HIE)?
- Bill insurance payers for clinical services
- Enable secure sharing of patient health information across organizations (Correct answer)
- Generate ICD-10 codes from clinical notes
- Manage physician scheduling and credentialing
Correct 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.
Question 7: Which access control model grants system permissions based on a user's job function or organizational role rather than individual identity?
- Discretionary Access Control (DAC)
- Mandatory Access Control (MAC)
- Role-Based Access Control (RBAC) (Correct answer)
- Attribute-Based Access Control (ABAC)
Correct 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.
