CHAA Healthcare Information Systems and Technology 2 — Questions and Answers
Question 1: What is the primary function of a Hospital Information System (HIS) in patient access?
- To replace all paper-based clinical documentation
- To manage patient registration, scheduling, billing, and administrative data across the facility (Correct answer)
- To provide diagnostic imaging services
- To automate surgical procedures
Correct answer: To manage patient registration, scheduling, billing, and administrative data across the facility
HIS serves as the central administrative system managing registration, scheduling, billing, and operational data that patient access staff interact with daily.
Hospital Information Systems integrate multiple functions critical to patient access: ADT (Admission/Discharge/Transfer), registration, scheduling, insurance verification, order entry, and billing. Patient access staff use HIS as their primary work tool, entering data that flows to clinical and financial systems. Modern HIS platforms often integrate with EHRs, creating a unified patient record across administrative and clinical domains.
Question 2: What does ADT stand for in healthcare information systems?
- Automated Diagnostic Testing
- Admission, Discharge, and Transfer (Correct answer)
- Advanced Data Transmission
- Administrative Decision Tool
Correct answer: Admission, Discharge, and Transfer
ADT tracks patient movement through the facility from admission through discharge and any transfers between units.
ADT is a core module of hospital information systems that tracks every patient's journey: admission (registering and assigning a bed), discharge (releasing and finalizing the encounter), and transfer (moving between units or levels of care). ADT data triggers bed management updates, census reporting, billing events, and clinical notifications. Accurate ADT processing by patient access ensures proper billing and bed utilization.
Question 3: Which system is used for real-time electronic insurance eligibility verification?
- The hospital's general ledger system
- Electronic Data Interchange (EDI) 270/271 transaction system (Correct answer)
- The pharmacy dispensing system
- The laboratory information system
Correct answer: Electronic Data Interchange (EDI) 270/271 transaction system
The 270/271 EDI transaction is the HIPAA standard for submitting eligibility inquiries (270) and receiving eligibility responses (271) electronically.
HIPAA mandates standard electronic transactions for administrative functions. The 270 transaction is the eligibility inquiry sent to the payer, and the 271 is the response containing coverage details, copays, deductibles, and plan specifics. These transactions occur in real-time through clearinghouses, replacing phone-based verification. Patient access staff initiate 270/271 transactions through their registration system to verify coverage before or during registration.
Question 4: What is a clearinghouse in the context of healthcare billing technology?
- A physical location where paper claims are sorted
- An intermediary that formats, scrubs, and routes electronic claims between providers and payers (Correct answer)
- A government agency that approves medical procedures
- A database of patient medical records
Correct answer: An intermediary that formats, scrubs, and routes electronic claims between providers and payers
Clearinghouses serve as intermediaries that validate, format, and route electronic claims and eligibility transactions between healthcare providers and insurance payers.
Healthcare clearinghouses receive claims from providers, validate them against payer requirements, translate them into the correct EDI format, and route them to the appropriate payer. They also return eligibility responses, claim status updates, and remittance advice. Major clearinghouses include Availity, Change Healthcare, and Waystar. Patient access benefits from clearinghouse services through real-time eligibility checks and claim status inquiries.
Question 5: Why is the Master Patient Index (MPI) critical to healthcare information systems?
- It stores all clinical notes for every patient
- It serves as the single source of truth linking a patient to all their records across systems (Correct answer)
- It manages medication prescriptions
- It tracks employee schedules and payroll
Correct answer: It serves as the single source of truth linking a patient to all their records across systems
The MPI assigns a unique identifier to each patient and links all encounters, records, and billing data across the enterprise.
The MPI is the backbone of patient identification across all healthcare information systems. It assigns an enterprise-wide unique medical record number (MRN) and links all encounters, registrations, orders, results, and billing records to the correct patient. MPI integrity is essential for patient safety (complete medical history), billing accuracy (consolidated accounts), and regulatory compliance. Patient access staff are the primary gatekeepers of MPI integrity.
Question 6: What is the purpose of a patient portal in the context of healthcare access?
- To replace in-person visits entirely
- To provide patients with online access to scheduling, registration, test results, and billing information (Correct answer)
- To allow physicians to prescribe medications remotely
- To manage hospital supply chain logistics
Correct answer: To provide patients with online access to scheduling, registration, test results, and billing information
Patient portals empower patients to manage administrative tasks online, reducing call volume and improving access to information.
Patient portals are web-based applications that give patients 24/7 access to scheduling, pre-registration, insurance card uploads, bill pay, cost estimates, and messaging. For patient access departments, portals shift routine tasks to self-service, reducing phone volume and wait times. Meaningful Use requirements incentivized portal adoption. Modern portals integrate with HIS and EHR systems, creating a seamless patient experience across digital and in-person channels.
