Clinical

Records the date on which a scheduled or ordered ultrasound procedure was formally cancelled by the patient, provider, or facility. Used in radiology scheduling systems to track cancellation patterns, measure no-show and cancellation rates, and support capacity planning and slot reallocation workflows.

Classifies an ultrasound procedure into a defined grouping such as obstetric, abdominal, vascular, cardiac, or musculoskeletal. Used in radiology information systems and claims reporting to organize imaging orders by clinical type, support procedure code assignment, and enable utilization analysis across sonographic imaging service lines.

The specific charge assessed for an ultrasound service rendered, reflecting the facility or professional fee schedule rate before payer adjustments. Used in revenue cycle and claims processing to initiate billing for sonographic imaging services and establish the gross charge basis for reimbursement negotiation and cost reporting.

The primary symptom or clinical concern documented by the ordering clinician that prompted the ultrasound order. Captured in radiology and EHR systems to guide sonographic protocol selection, support medical necessity validation, and link imaging orders to clinical indications for diagnostic reporting.

Identifies a subordinate ultrasound record linked to a parent imaging encounter in a hierarchical study structure. Used in radiology information systems to associate follow-up scans, additional image series, or supplemental sonographic views with the originating parent ultrasound order or encounter.

The municipality where the ultrasound procedure was performed or where the ordering facility is located. Used in radiology and claims data to identify the geographic service location, support regional utilization reporting, and associate imaging encounters with facility-level geographic attributes.

The classification tier assigned to an ultrasound study, such as routine, urgent, or emergent, or the anatomical category such as obstetric, vascular, or abdominal. Used in radiology scheduling and reporting systems to prioritize worklists, assign protocols, and categorize imaging volumes by study type.

The standardized procedural or diagnostic code assigned to an ultrasound study, typically a CPT or HCPCS code identifying the specific sonographic service performed. Used in radiology systems and claims processing to enable billing, reimbursement, and cross-system identification of imaging procedures.

Free-text notation entered by radiologists, sonographers, or ordering clinicians to capture supplemental observations, technical limitations, patient cooperation notes, or clinical context not accommodated in structured fields within the ultrasound study record or radiology information system.

The calendar date on which the ultrasound examination was fully performed and the image acquisition was finalized. Recorded in radiology information systems to track study turnaround times, measure imaging workflow efficiency, and establish the clinical service date for billing and reporting purposes.

A flag designating that an ultrasound study contains sensitive information requiring restricted access, such as reproductive health, HIV-related, or substance abuse imaging encounters. Controls record visibility in EHR and radiology systems to ensure compliance with applicable privacy regulations and consent directives.

The total number of ultrasound studies associated with a patient, encounter, order, or reporting period. Used in radiology data warehouses and clinical analytics to quantify imaging utilization, track repeat imaging patterns, and support population-level reporting on sonographic procedure volumes.

The nation where the ultrasound procedure was performed or where the associated facility is located. Captured in radiology and claims data systems to support international care coordination, cross-border claims processing, and geographic segmentation in imaging utilization and outcomes reporting.

The unique identifier of the user, system, or application that originally created the ultrasound record in the radiology information or health information system. Used for audit trail management, data provenance tracking, and accountability in clinical workflow and system integration contexts.

The calendar date on which the ultrasound record was first entered into the radiology information or health information system. Supports audit trail integrity, data lineage tracking, and workflow analytics by establishing when the study record was initiated relative to scheduling and service dates.

The timestamp recording the exact time the ultrasound record was first created in the radiology information or health information system. Used alongside the created date to establish precise record-entry timestamps for audit compliance, workflow sequencing analysis, and data provenance documentation.

The serum creatinine laboratory value documented in association with an ultrasound order or encounter, used to assess renal function prior to contrast-enhanced sonographic studies. Captured in radiology and EHR systems to support safety screening and clinical decision-making for contrast administration protocols.

The calendar date associated with an ultrasound study, representing the date the imaging service was performed or scheduled. Used across radiology information systems, EHR platforms, and claims data to anchor the sonographic encounter to a specific point in time for clinical and administrative reporting.

The combined date and time value marking when an ultrasound event occurred, such as study performance, order placement, or report finalization. Captured in radiology and health information systems to enable precise temporal sequencing of imaging workflow events and support time-sensitive clinical documentation requirements.

The Drug Enforcement Administration registration number associated with a prescribing clinician linked to an ultrasound order, typically relevant when imaging is ordered in conjunction with controlled substance management. Used to validate prescriber credentials and maintain regulatory compliance in integrated ordering workflows.
