A boolean indicator identifying the primary or preferred record among multiple related records in a healthcare data system. Used to identify primary diagnosis codes, primary insurance coverage, primary care physicians, and primary addresses when multiple values exist for the same entity.

The calendar date on which a clinical procedure documented within a healthcare record was performed. Used for chronological sequencing of care events, claims adjudication alignment, and retrospective auditing of procedural timelines within patient medical records.

Indicates whether a consolidated clinical or administrative summary document has been reviewed and approved by an authorized clinician or administrator. Tracks the workflow state of the summary through review stages such as pending, approved, or rejected prior to distribution or filing.

A decentralized data architecture paradigm that treats data as a product owned and served by domain teams rather than managed by a central data engineering team, with each domain responsible for the quality, documentation, and accessibility of its own data products. In healthcare organizations, a data mesh approach assigns data product ownership to clinical, claims, pharmacy, and operations domains, reducing the central data team bottleneck while establishing platform-level standards for interoperability and governance.

The timestamp indicating the exact time a hospital record was last updated in the clinical or administrative system. Combined with the modified date, it provides a precise audit trail of data changes within inpatient facility information systems for compliance and governance.

The racial category self-reported or recorded for a patient, based on standard classifications such as OMB categories. Captured in clinical and enrollment systems to support population health reporting, health equity analysis, and federally mandated demographic data collection.

The combined date and time value capturing when a specific insurance coverage event occurred or was recorded. Used in member enrollment and claims adjudication systems to establish an exact chronological record of coverage changes, eligibility updates, or benefit activations.

The unit of measure defining the interval or count of a medication or treatment administration schedule, such as doses per day or administrations per week. Used in clinical systems to standardize dosing frequency expressions and support accurate medication order entry and pharmacy dispensing workflows.

The date on which a LOINC code becomes active and valid for use in clinical observation reporting and lab result documentation. Used in terminology management systems to control when newly published or updated LOINC codes may be applied in EHR orders, lab interfaces, and interoperability data exchanges.

The calendar date on which a specific care management or clinical intervention was performed or initiated for a member. Used across case management, disease management, and utilization management programs to sequence care activities, measure response times, and support longitudinal reporting of member engagement.
