experience totalexp_tot

The aggregate numeric value representing a summed measurement or cost associated with a patient service encounter, such as total charges, total services rendered, or total clinical observations recorded. Used in healthcare financial and utilization reporting to assess encounter-level resource consumption.

experience total countexp_tot_cnt

The cumulative number of occurrences, events, or records associated with a patient service encounter or defined experience category. Used in healthcare analytics to measure encounter volume, service utilization frequency, and patient interaction density across populations, time periods, or care settings.

experience typeexp_typ

A categorical classification that identifies the nature or mode of a patient service encounter, such as inpatient, outpatient, telehealth, or emergency. Used in healthcare data systems to segment utilization, support claims adjudication, and enable encounter-specific reporting and analytics.

experience updated dateexp_upd_dt

The most recent date on which a patient service encounter record was modified, corrected, or supplemented. Used in healthcare data management to support audit trails, track record amendments, identify late-arriving data, and ensure data integrity across clinical and administrative systems.

experience urgencyexp_urg

A coded or descriptive indicator reflecting the clinical time-sensitivity or priority level assigned to a patient service encounter, such as routine, urgent, or emergent. Used in triage workflows, care coordination, and utilization management to appropriately route and prioritize patient care delivery.

experience valueexp_val

A discrete quantitative or qualitative data point captured in association with a patient service encounter, representing a specific clinical observation, metric, or outcome measure. Used in healthcare analytics and clinical documentation to support evidence-based assessment, benchmarking, and population health reporting.

experience versionexp_ver

A sequential numeric or alphanumeric identifier tracking the revision history of a patient service encounter record. Used in healthcare data management to distinguish original entries from subsequent updates, supporting audit compliance, data lineage tracking, and resolution of conflicting encounter information.

experience zipexp_zip

The five or nine digit postal code associated with the location of a patient service encounter or the patient's address at time of service. Used in healthcare data systems to support geographic analysis, population health stratification, network adequacy assessment, and regional utilization reporting.

finding valuefndg_val

The discrete quantitative or qualitative result associated with a clinical finding or diagnostic assessment, such as a lab result, imaging interpretation, or physical exam observation. Used in clinical documentation systems to capture, store, and trend objective clinical data supporting diagnosis and treatment decisions.

follow up after emergency for mental illnessfum

A HEDIS measure assessing the percentage of members 6 years and older who had a visit to an emergency department with a principal diagnosis of mental illness or intentional self-harm and had a follow-up visit with a mental health practitioner within 7 and 30 days after the ED visit. FUM is distinct from FUH which follows inpatient hospitalization and is included in CMS Star Ratings and behavioral health quality programs targeting high-utilization members with mental health conditions.

follow up after hospitalizationfuh

A HEDIS measure assessing the percentage of members 6 years and older who were hospitalized for a mental illness or intentional self-harm and had a follow-up visit with a mental health practitioner within 7 and 30 days after discharge. Follow-Up After Hospitalization for Mental Illness is one of the highest-weighted HEDIS behavioral health measures and is included in CMS Star Ratings, with poor performance associated with higher readmission rates and increased risk of self-harm recurrence.

frequency valuefreq_val

The numeric or coded representation of how often a medication, treatment, or clinical intervention is administered, such as twice daily or every eight hours. Used in pharmacy and clinical order management systems to drive dispensing logic, dosing schedules, medication adherence tracking, and utilization analysis.

full riskfull_rsk_ind

A boolean indicator identifying a healthcare payment arrangement in which a provider organization accepts complete financial accountability for the total cost of care for a defined population, bearing both upside savings potential and full downside loss exposure without the risk corridor protections or loss sharing limits typical of intermediate value based payment models. Full risk arrangements represent the endpoint of the value based payment progression — organizations that accept full risk operate as risk-bearing entities similar to insurance companies and must comply with state insurance regulations in many markets. Medicare Advantage plans accept full risk from CMS through the capitation payment system. Provider-sponsored organizations and integrated delivery systems with mature care management capabilities may accept full professional or global risk from health plans through delegated risk arrangements. Healthcare data teams supporting full risk organizations build comprehensive financial reporting systems that reconcile capitation receipts against claim costs, track medical loss ratios, calculate IBNR reserves for incurred but not yet reported claims, and produce actuarial analyses supporting regulatory capital adequacy requirements.

gastroenterology valuegi_val

A discrete data point or measurement specific to digestive system specialty care, such as an endoscopy finding, GI function score, or gastroenterology procedure result. Used in specialty clinical documentation and analytics to track gastrointestinal health outcomes, procedure volumes, and disease progression over time.

global riskglbl_rsk_ind

A boolean indicator identifying a value based care arrangement in which a provider organization or health plan accepts full financial responsibility for the total cost of all healthcare services for an attributed population, receiving a fixed capitation payment that covers all covered services regardless of actual utilization. Global risk is the most advanced form of value based payment, transferring essentially all insurance risk from the payer to the provider organization. Under global risk arrangements, provider organizations act as quasi-insurers — they profit when they deliver care efficiently below the capitation rate and lose money when care costs exceed the capitation amount. Global risk requires sophisticated actuarial capabilities, robust care management infrastructure, and adequate financial reserves to withstand adverse utilization experience. Healthcare data teams build global risk financial management systems that track capitation receipts, aggregate all attributed member claims costs, calculate monthly and quarterly profit and loss positions under the global risk arrangement, and model reserve requirements based on actuarial projections of potential loss scenarios.

group valuegrp_val

A numeric or coded data point representing a measurement, aggregate figure, or attribute associated with a defined insurance group or employer plan. Used in member enrollment and benefits administration systems to support group-level billing, plan performance analysis, and population health reporting by coverage segment.

guarantor valueguar_val

A numeric or descriptive data point associated with the financially responsible party for a patient account, such as a payment amount, account balance, or coverage percentage. Used in healthcare revenue cycle systems to track financial accountability, support billing workflows, and manage collections for patient accounts.

guideline valuegdln_val

A specific threshold, target, or recommended parameter drawn from clinical practice guidelines, used to evaluate patient care decisions or outcomes against evidence-based standards. Used in quality measurement, clinical decision support, and care management programs to assess adherence to established best practices and protocols.

hcpcs valuehcpcs_val

The specific HCPCS Level I or Level II code value assigned to a procedure, service, or supply on a medical claim. HCPCS codes are used by payers and providers to identify billable services for reimbursement under Medicare, Medicaid, and commercial health plans.

health outcomes surveyhos

The Medicare Health Outcomes Survey administered by CMS to Medicare Advantage plan members to assess physical and mental health status using the SF-36 or VR-12 instrument, measuring changes in health status over a two-year period between baseline and follow-up surveys. HOS results are included in CMS Star Ratings and measure the health plan's effectiveness in maintaining or improving member health status, with improvement rates calculated by comparing follow-up scores to baseline predictions based on case-mix adjustment.
