The actual dollar amount reimbursed by the payer for a vaccine administration encounter, recorded in claims and billing systems. Reflects the adjudicated payment after applying contractual adjustments, copays, and deductibles. Used in immunization program financial reconciliation and cost tracking.

The calendar date on which payment was issued by the payer for a vaccine administration claim. Used in immunization billing reconciliation to track reimbursement timelines, identify delayed payments, and align financial records with adjudicated claims in healthcare billing systems.

Foreign key or hierarchical reference linking a child immunization record to its parent encounter, series, or patient record in EHR and immunization registry systems. Critical for data engineers building vaccination series hierarchies, such as multi-dose COVID-19 or hepatitis B schedules in HL7 or FHIR pipelines.

Calculated ratio representing vaccination coverage or series completion rates within a defined member population, used in quality reporting systems such as HEDIS, CMS Star Ratings, and population health platforms. Data engineers use this metric to assess compliance thresholds against NCQA or state immunization benchmarks.

Defined date range during which a vaccination record is considered valid or reportable, as tracked in EHR systems, payer claims, and immunization information systems. Data engineers use this field to filter vaccination events within measurement years for HEDIS quality measures or CMS reporting cycles.

Telephone contact number associated with the administering provider, clinic, or patient record tied to a vaccination event in EHR and immunization registry systems. Used by data engineers during provider directory reconciliation, outreach campaign processing, and immunization recall workflows in population health platforms.

The documented clinical plan associated with a patient's vaccination encounter, including scheduled follow-up doses, vaccine series sequencing, and any post-administration monitoring instructions. Supports immunization schedule management and care coordination within clinical documentation systems.

The insurance policy identifier associated with the patient's coverage at the time of vaccine administration. Used in immunization billing and claims processing to link the vaccination encounter to the correct health plan, enabling accurate adjudication and reimbursement tracking.

The patient's preferred name or display name recorded at the time of vaccine administration. Used in immunization registries and clinical systems to ensure patient-friendly communication, consent documentation, and accurate matching across immunization records and registry submissions.

The billed or list price of a vaccine dose at the time of administration, prior to payer adjustments or discounts. Used in immunization program cost analysis, vaccine inventory valuation, and financial reporting to compare actual reimbursement against the charged amount for the vaccination encounter.

A flag identifying whether a vaccination record represents the primary or initial dose in a multi-dose series, or designates the primary immunization event when duplicate records exist. Used in immunization registries to ensure accurate series tracking and prevent redundant dose reporting.

Coded ranking value assigned to a vaccination record indicating clinical or public health urgency, such as CDC ACIP tier classifications or state emergency prioritization during outbreak response. Used in EHR and population health systems by data engineers to sequence immunization outreach and eligibility workflows.

Records the patient's heart rate measured at the time of vaccine administration as a pre- or post-vaccination vital sign. Documented in clinical records to assess patient fitness for vaccination, monitor for immediate adverse reactions such as anaphylaxis, and support clinical decision-making.

Numeric value representing the dose amount or number of vaccine units administered during a vaccination event, expressed in milliliters or dose counts within pharmacy, EHR, and claims systems. Data engineers use this field to validate NDC-level dispensing records against administered dose records in PBM and medical claims reconciliation.

The patient's self-reported or recorded racial category captured at the time of vaccine administration. Used in immunization registry reporting and public health surveillance to monitor vaccination coverage disparities, support equity initiatives, and comply with state and federal immunization reporting requirements.

Minimum and maximum boundary values defining acceptable age windows, dose intervals, or titer thresholds for a vaccination record in EHR, immunization registry, or clinical decision support systems. Data engineers apply this field when building ACIP schedule validation logic or CDC immunization forecasting rule engines.

Unit cost or reimbursement amount associated with a vaccine administration event in medical claims, fee schedule, or PBM adjudication systems. Data engineers use this field to calculate total immunization spend, validate allowed amounts against CMS vaccine fee schedules, and support cost trend reporting in payer financial analytics platforms.

A scored assessment value associated with a vaccination encounter, such as a patient-reported experience score, adverse event severity rating, or quality measure rating. Used in immunization program quality reporting, HEDIS measure tracking, and population health performance evaluation.

A calculated proportional value related to immunization program performance, such as vaccination coverage rate, series completion ratio, or dose-to-population ratio. Used in public health reporting and population health analytics to evaluate immunization program effectiveness across defined patient cohorts.

Coded or free-text explanation documenting the clinical or public health rationale for administering a vaccine, captured in EHR systems using ICD-10-CM Z-codes or HL7 FHIR reason reference elements. Data engineers use this field to classify vaccination intent, such as routine preventive, post-exposure prophylaxis, or travel immunization, in quality and claims pipelines.
