Technology

A boolean indicator marking a record that failed validation or processing rules in a healthcare data system. Used in ETL pipelines, claims adjudication, and EDI processing to tag records requiring manual review or reprocessing. Error flag records are quarantined from production data until resolved.

Unique system-generated key assigned to a clinical evaluation or diagnostic assessment record within EHR and care management systems. Enables tracking of patient assessments, screening results, and clinical findings across care episodes, quality reporting, and utilization management workflows.

Unique system-generated key assigned to a patient experience or satisfaction survey record within healthcare quality and member engagement systems. Supports tracking of patient-reported perceptions of care quality across CAHPS reporting, value-based care programs, and member experience analytics.

Unique system-generated key assigned to a clinical finding record representing an observed or measured result from a patient assessment within EHR and clinical data systems. Enables tracking of diagnostic findings, abnormal results, and clinical observations across care documentation and quality reporting workflows.

A column in a healthcare data table that references the primary key of another table to establish a relationship between the two tables. Used to enforce referential integrity in normalized and dimensional data models. Examples include member_key in a claims table referencing the member dimension table.

Unique system-generated key assigned to a medication or treatment frequency record within pharmacy and clinical management systems. Supports tracking of administration schedules and dosing intervals across prescription management, medication adherence monitoring, and clinical decision support workflows.

Unique system-generated key assigned to a gastroenterology specialty record or encounter within clinical and claims systems. Enables tracking of digestive system diagnoses, endoscopic procedures, and specialist referrals across care management platforms, utilization reporting, and specialty network workflows.

Unique system-generated key assigned to a geriatric specialty record or encounter within clinical and care management systems. Enables tracking of elderly patient care plans, specialist visits, and age-related condition management across long-term care, population health, and utilization reporting workflows.

Unique system-generated key assigned to a benefit group or employer group record within member enrollment and insurance administration systems. Links members to their specific plan group for eligibility verification, premium billing, coverage determination, and group-level utilization reporting.

Unique system-generated key assigned to the financially responsible party for a patient account within healthcare billing and revenue cycle systems. Enables tracking of guarantor payment obligations, statement delivery, and account balances across patient financial services and accounts receivable workflows.

Unique surrogate key assigned by the source system to a clinical practice guideline record. Enables consistent cross-system tracking of evidence-based care recommendations used in quality programs, clinical decision support, and care management protocol alignment.

A cryptographic hash value generated from one or more business key columns used as a surrogate key in Data Vault 2.0 healthcare data models. Typically generated using MD5 or SHA-256 algorithms. Enables consistent key generation across distributed systems and supports parallel loading of hub and link tables.

Unique surrogate key assigned by the source system to an HCPCS procedure code record. Used in medical claims processing and billing systems to track CMS-standardized codes representing services, supplies, and equipment submitted on professional and outpatient facility claims.

Health Insurance Portability and Accountability Act — federal law establishing national standards for protecting sensitive patient health information. HIPAA Privacy Rule governs PHI use and disclosure. Security Rule sets standards for electronic PHI safeguards including encryption, access controls, and audit logging. Essential compliance framework for healthcare data engineers building data warehouses, APIs, and analytics pipelines that process member or patient data.

Process of matching and linking patient or member records across disparate healthcare systems to create a unified master patient identity. Identity resolution uses deterministic and probabilistic matching algorithms on attributes like name, date of birth, address, and SSN. Healthcare data engineers implement identity resolution pipelines to support master patient index creation, care coordination, and longitudinal patient record assembly.

Unique surrogate key assigned by the source system to a clinical or operational quality indicator record. Supports performance measurement tracking across care quality programs, HEDIS measures, and population health reporting initiatives within health plan and provider systems.

Unique surrogate key assigned by the source system to a clinical assessment instrument or standardized screening tool record. Enables tracking of validated measurement tools such as PHQ-9 or GAD-7 used in clinical documentation, outcomes reporting, and quality measurement workflows.

Unique surrogate key assigned by the source system to a health insurance carrier record. Used in claims adjudication, coordination of benefits, and member enrollment systems to identify the payer entity responsible for coverage and reimbursement across insurance products.

Unique surrogate key assigned by the source system to a clinical intervention record. Supports longitudinal tracking of therapeutic actions, care management activities, and preventive services applied to members across care coordination, claims, and population health platforms.

Unique surrogate key assigned by the source system to a patient intolerance record. Used in clinical documentation and pharmacy systems to track non-immunologic adverse reactions to foods, drugs, or substances that inform prescribing decisions and care plan development.
