Member

Records the name or system identifier of the individual or automated process that granted approval for a health plan member's enrollment, plan change, or authorization request. Used in audit trails and compliance reporting to document accountability within enrollment and utilization management workflows.

The recorded time at which a health plan member arrived for a scheduled or unscheduled healthcare encounter at a facility. Used in care coordination, utilization management, and operational reporting to measure wait times, throughput efficiency, and adherence to appointment scheduling protocols.

The calendar date on which a health plan member arrived for a healthcare encounter at a clinical facility. Used in utilization management, claims adjudication, and care coordination systems to establish the encounter timeline and validate service dates against member eligibility and authorization periods.

A structured or narrative clinical evaluation of a health plan member's health status, functional needs, or care requirements. Captured in care management and disease management programs to document findings from health risk assessments, care plan reviews, or case management intake evaluations.

The assignment of a health plan member to a specific primary care provider or care team for quality measurement, value-based care program participation, and care management purposes. Attribution methodologies vary by program — CMS uses plurality of primary care visits for Medicare Shared Savings Program attribution while health plans may use voluntary assignment or claims-based algorithms. Attribution drives provider accountability in pay-for-performance programs and determines which provider receives quality bonuses or shared savings distributions. Healthcare data teams build attribution pipelines that process claims data to identify plurality providers, apply program-specific rules, and produce stable member-provider assignment tables used in HEDIS calculation and provider performance reporting.

The calculated mean value of a specific member metric such as average premium, average utilization, or average cost across a defined population. Used in actuarial analysis, population health management, and member segmentation to understand typical member behavior and cost patterns.

The outstanding financial amount owed by or attributed to an insurance plan enrollee, reflecting unpaid premiums, deductible accumulators, or cost-sharing liabilities in payer and claims adjudication systems. Data engineers reference this field for accounts receivable reporting, member financial risk stratification, and premium reconciliation workflows in enrollment and billing platforms.

The calendar or fiscal year period associated with a health plan member enrollment for the purpose of tracking annual benefit limits, accumulator balances, and eligibility windows. The benefit year defines the twelve-month window during which deductibles accumulate, out-of-pocket maximums apply, and visit-based benefit limits are enforced. Most commercial plans use a January through December calendar year benefit cycle though employer-sponsored plans may use fiscal year cycles. Medicare Advantage always uses a calendar year benefit cycle. Healthcare data teams use mbr_bnft_yr as a partitioning and filtering key in benefit accumulator tables, HEDIS measure calculation pipelines, and annual cost reporting to correctly scope claims and clinical events to the appropriate measurement year without cross-year contamination.

The total dollar amount charged by a provider for services rendered to a health plan member before any contractual adjustments, plan payments, or member cost-sharing are applied. Recorded in claims processing systems as the starting point for adjudication and reimbursement calculations.

The recorded date of birth for an insurance plan enrollee, sourced from 834 enrollment transactions, EHR registration, or CMS eligibility files. Data engineers use this field for age-band calculations, pediatric vs. adult cohort segmentation, Medicare eligibility validation, and ACA compliance reporting where age is a rating factor in premium determination.

The effective date on which a health plan member's enrollment, authorization, referral, or service request was cancelled. Recorded in enrollment and utilization management systems to document coverage termination timelines, support retroactive eligibility adjustments, and trigger downstream billing corrections.

The assignment of a designated care coordinator, nurse navigator, or care team to a health plan member to facilitate integrated healthcare delivery across multiple providers, settings, and services. Care coordination is a core function of Medicare Advantage and Medicaid managed care plans, particularly for members with complex chronic conditions, recent hospitalizations, or high-risk social determinants of health. Effective care coordination reduces fragmented care, prevents avoidable readmissions, improves medication adherence, and closes care gaps. Healthcare data teams use mbr_care_coord in care management platforms to track coordinator assignments, measure caseloads, monitor intervention completion rates, and report care coordination program outcomes for NCQA accreditation, CMS Star Ratings, and value-based care contract performance measurement.

An identified gap between evidence-based recommended healthcare services and the services a member has actually received during a measurement period. Care gaps are derived from HEDIS measures and clinical guidelines identifying members overdue for preventive screenings, chronic disease management visits, medication adherence thresholds, or follow-up care after hospitalization. Closing care gaps directly improves HEDIS rates and CMS Star Ratings for Medicare Advantage plans. Healthcare data teams build care gap identification pipelines that compare recommended service schedules against claims and lab data, produce member-level gap lists for outreach, and track gap closure rates by provider, geography, and member demographics.

A coordinated healthcare delivery approach that proactively manages a health plan member health needs through structured clinical programs, outreach, and care coordination services. Member care management includes disease management for chronic conditions, case management for high-cost members, transitional care after hospitalization, and preventive care outreach for care gap closure. Medicare Advantage plans are required to offer care management programs to high-risk members. Healthcare data teams build care management eligibility and outcomes pipelines that identify members for program enrollment using risk scores and care gaps, track program participation, measure clinical and financial outcomes, and report effectiveness to health plan leadership and CMS.

A classification label assigned to an insurance plan enrollee within clinical and administrative workflows, used to group members by risk tier, program eligibility, or care pathway in EHR, payer, and population health systems. Data engineers rely on this field for cohort-based reporting, care management integrations, and downstream analytics segmentation across enrollment and clinical platforms.

The dollar amount a health plan member is responsible for paying out-of-pocket for a covered healthcare service, reflecting cost-sharing obligations such as deductibles, copays, and coinsurance after plan adjudication. Used in member billing statements and explanation of benefits documents.

The primary symptom, condition, or reason for seeking care as reported by or on behalf of a health plan member during a clinical encounter. Documented in care management and utilization review systems to guide clinical assessment, triage decisions, and authorization determinations for requested services.

A designation identifying an insurance plan enrollee as a dependent child under a subscriber's coverage, sourced from 834 enrollment transactions and eligibility files in payer and PBM systems. Data engineers use this field to establish family hierarchies, apply age-out rules for dependent eligibility, and support pediatric utilization reporting and CHIP compliance analytics.

An indicator, count, or coded list of chronic medical conditions identified for a health plan member based on claims diagnosis history, pharmacy utilization, or clinical assessment data. Chronic conditions include diabetes, heart failure, chronic obstructive pulmonary disease, hypertension, coronary artery disease, depression, and other long-term health conditions that require ongoing medical management. CMS identifies members with multiple chronic conditions for Medicare Advantage care management program targeting. Chronic condition status drives HCC risk adjustment coding, HEDIS chronic disease quality measure denominator identification, and care management program eligibility. Healthcare data teams derive mbr_chrnc_cond from claims-based condition algorithms such as the CMS Chronic Conditions Warehouse definitions, maintaining condition flags with evidence dates for longitudinal population health analytics.

The city component of an insurance plan enrollee's primary residence address, sourced from 834 enrollment files, CMS eligibility feeds, or EHR registration systems. Data engineers use this field alongside state and ZIP for geographic cohort analysis, service area reporting, network adequacy assessments, and regional care utilization benchmarking in payer and population health platforms.
