Unique system-generated key assigned to a patient's legally documented end-of-life care instructions, including DNR orders and living wills. Enables consistent retrieval of directive records across clinical systems to ensure care decisions honor patient wishes.

Unique system-generated key assigned to a licensed anesthesiologist's record within clinical and surgical systems. Used to link anesthesia administration events, credentialing data, and operative documentation to the responsible anesthesia provider across care encounters.

An open table format for large-scale analytic datasets that provides ACID transactions, schema evolution, partition evolution, and time travel capabilities on cloud object storage, serving as an alternative to Delta Lake and Apache Hudi in open data lakehouse architectures. Apache Iceberg is increasingly adopted in healthcare data platforms seeking vendor-neutral interoperability across multiple query engines including Spark, Trino, Flink, and Snowflake external tables.

Unique system-generated key assigned to a scheduled patient care visit record. Used to track scheduling, confirmations, cancellations, and no-shows across scheduling and practice management systems, supporting patient access reporting and provider utilization analysis.

Unique system-generated key assigned to a formal service or treatment approval record. Used in utilization management and payer systems to link approval decisions to specific requests, enabling audit trails and downstream claims adjudication validation.

Unique system-generated key assigned to a structured clinical evaluation record, such as a nursing assessment or functional status screen. Enables linkage of assessment results to care plans, diagnoses, and outcome tracking across clinical documentation systems.

Unique system-generated key assigned to a healthcare support staff member record, such as a medical or surgical assistant. Used to attribute tasks, procedures, and documentation to the correct support personnel across clinical and workforce management systems.

Unique system-generated key assigned to a prior authorization record issued by a payer for a specific service or medication. Used across utilization management, claims, and clinical systems to validate service approvals and ensure correct adjudication of related claims.

Unique system-generated key assigned to a patient or account financial balance record. Used in revenue cycle and billing systems to track outstanding amounts owed after payments, adjustments, and insurance processing, supporting collections and accounts receivable workflows.

Unique system-generated key assigned to a patient billing statement or invoice record. Used in revenue cycle systems to track itemized service charges, payment status, and statement delivery across billing cycles and patient financial responsibility workflows.

The first layer in a medallion architecture containing raw, unprocessed data ingested directly from source systems with minimal transformation, preserving the original structure, format, and values exactly as received. In healthcare data platforms, the bronze layer typically stores raw EDI 837 files, HL7 messages, EHR extracts, and lab result feeds in their native formats, serving as an immutable audit trail that enables reprocessing when downstream logic changes.

A FHIR specification capability defined in the FHIR Bulk Data Access Implementation Guide that enables large-scale asynchronous export of FHIR resources for entire patient populations, used for data analytics, population health management, and payer-to-provider data exchange at scale. Bulk FHIR export returns newline-delimited JSON files containing FHIR resources such as Patient, Claim, and ExplanationOfBenefit, and is required under the CMS Interoperability Rules for payer data sharing.

Unique system-generated key assigned to a facility or unit capacity record defining maximum patient volume or resource limits. Used in bed management, scheduling, and operational systems to monitor census thresholds and support capacity planning decisions.

Unique system-generated key assigned to a cardiology-specific clinical record, such as a cardiac procedure, diagnostic study, or specialty encounter. Enables linkage of cardiovascular care data across EHR, imaging, and diagnostic systems for longitudinal heart care tracking.

A data integration technique that identifies and captures changes — inserts, updates, and deletes — made to source system databases and streams those changes to downstream data pipelines in near real-time, without requiring full table scans. In healthcare data engineering, CDC is used to replicate EHR, claims, and eligibility system changes into data warehouses with minimal latency, typically implemented using database transaction log reading tools such as Debezium, AWS DMS, or native Snowflake streams.

Unique system-generated key assigned to an individual service charge record generated during a patient encounter. Used in charge capture and revenue cycle systems to link billable service fees to encounters, payers, and claims for accurate reimbursement processing.

Unique system-generated key assigned to a patient's medical record or chart within a clinical system. Serves as the primary reference linking all clinical documentation, orders, results, and encounter notes to a single patient record across care settings.

Unique system-generated key assigned to a clinical chemistry laboratory record, such as a metabolic panel or blood chemistry test. Used to track specimen processing, result reporting, and reference range interpretation across laboratory information and EHR systems.

A subject-oriented, integrated, time-variant, and non-volatile data store combining clinical, claims, and operational data from across a healthcare organization to support population health analytics, quality reporting, research, and executive decision making. Unlike a transactional clinical data repository optimized for individual patient lookup, a clinical data warehouse uses dimensional modeling with fact and dimension tables optimized for aggregate queries across large patient populations.

A data governance feature that controls access to specific columns within a database table based on user role or policy, enabling organizations to expose a table to analysts while masking or restricting sensitive columns containing PHI such as member name, date of birth, or Social Security Number. Column-level security is used in healthcare data platforms to implement HIPAA minimum necessary access principles without requiring separate physical copies of tables for different user groups.
