Population

A binary flag indicating whether a vaccination record is currently active and valid within the clinical system, as opposed to voided, historical, or superseded. Used during patient immunization history retrieval, registry data exchange, and deduplication processes to filter out inactive or erroneous vaccination entries.

A coded status value representing the current lifecycle state of a vaccination record, such as active, inactive, entered-in-error, or historical. Used to manage immunization record visibility in clinical workflows, registry submissions, and longitudinal patient vaccination history reviews across care settings.

The full physical address text of the location where a vaccine was administered, including street, city, state, and ZIP. Used to identify and validate the administration site for immunization registry reporting, geographic disease surveillance, and provider facility verification in population health programs.

A monetary value representing a financial modification applied to a vaccination claim or billing transaction, such as a contractual adjustment, discount, or correction. Used in vaccine program billing reconciliation, VFC program cost accounting, and adjudication of immunization-related healthcare claims.

The patient's age in years, months, or days at the time of vaccine administration, calculated from date of birth. Used to validate age-appropriate dosing per ACIP schedules, assess eligibility for age-specific vaccine formulations, and support pediatric immunization coverage reporting and catch-up schedule calculations.

The maximum dollar amount a payer will reimburse for a specific vaccination service based on the contracted fee schedule or plan benefit design. Used in claims adjudication to determine payment limits and calculate member cost-sharing obligations such as copays and coinsurance.

The monetary value associated with a vaccination encounter, representing the total financial transaction for immunization services rendered. Used in healthcare billing and claims processing to record the cost of vaccine administration and related clinical services provided to a patient.

Indicates whether a vaccination has been authorized, pending review, denied, or completed within a clinical or administrative workflow. Used in immunization management systems to track the current authorization state of a vaccine order from initiation through administration and documentation.

Identifies the clinician, pharmacist, or authorized healthcare personnel who granted approval for a vaccination to proceed. Used in immunization records and clinical audit trails to establish accountability and meet documentation requirements for vaccine ordering and administration workflows.

The recorded timestamp indicating when a patient arrived at a clinical setting for a scheduled or walk-in vaccination appointment. Used in immunization workflow tracking to measure patient throughput, appointment adherence, and time-to-administration metrics within vaccination programs.

The calendar date on which a patient presented to a healthcare facility or immunization clinic for vaccine administration. Used in immunization records to establish the timeline of the vaccination encounter and support scheduling, follow-up dose tracking, and public health reporting requirements.

The clinician's documented clinical evaluation of a patient prior to or following vaccine administration, including observations about eligibility, contraindications, and patient response. Used in immunization records to capture pre-vaccination screening findings and post-administration monitoring notes.

The remaining unpaid dollar amount owed by a patient or payer for vaccination services after insurance payments, adjustments, and credits have been applied. Used in healthcare billing systems to track outstanding receivables and manage patient financial responsibility for immunization encounters.

The total dollar amount submitted by a healthcare provider to a payer or patient for vaccination services rendered, reflecting the provider's standard charge before adjustments or payments. Used in claims processing to initiate reimbursement and establish the basis for adjudication calculations.

The date of birth of the patient receiving a vaccination, used to verify age eligibility, determine appropriate vaccine formulations, and apply age-based immunization schedules. Critical in immunization registries and claims processing to ensure the correct vaccine type and dosage are administered.

The systolic and diastolic arterial pressure measurement recorded during a vaccination encounter as part of pre-administration screening or routine vital sign documentation. Used in immunization clinical records to assess patient stability and identify contraindications before vaccine administration proceeds.

The calendar date on which a previously scheduled vaccination appointment or vaccine order was officially cancelled by the patient, provider, or administrative staff. Used in immunization scheduling systems to track appointment utilization, reschedule outreach, and maintain accurate immunization history records.

A classification grouping that identifies the type or disease target of a vaccine, such as influenza, COVID-19, hepatitis, or childhood series. Used in immunization registries and public health reporting to organize vaccine records, support coverage analysis, and align with standardized immunization schedule categories.

The fee assessed for vaccination services including vaccine product cost and administration charges submitted on a claim or billing statement. Used in healthcare revenue cycle management to establish the gross charge before payer-negotiated adjustments, contractual write-offs, and patient cost-sharing amounts are applied.

The primary reason or presenting concern documented by a patient at the start of a vaccination encounter, such as seeking a required travel vaccine or reporting a previous immunization reaction. Used in clinical documentation to capture patient-reported context and support triage during vaccination visits.
