Quality

The five- or nine-digit postal code associated with the geographic location relevant to a healthcare performance metric observation. Used in population health analytics and geographic reporting to segment metric results by service area, enabling regional performance comparison and health equity analysis.

The floor performance level on quality measures that an Accountable Care Organization or health plan must achieve across required measure domains to be eligible to receive any shared savings distribution or quality bonus payment in a value based care contract. Minimum attainment requirements prevent organizations from gaming financial incentives by generating cost savings through care rationing rather than efficient care delivery — organizations must demonstrate acceptable quality before receiving financial rewards for cost reduction. CMS MSSP minimum attainment is set at the 30th percentile of national ACO quality performance for each measure, with organizations that fail to meet minimum attainment on any required measure domain becoming ineligible for shared savings regardless of cost performance. Healthcare data teams track minimum attainment thresholds by measure and performance year, calculate current attainment status throughout the year, generate alerts when performance drops below minimum attainment levels requiring urgent quality improvement intervention, and report attainment status to clinical leadership as a leading indicator of shared savings eligibility risk.

A quantified measure representing the prevalence, incidence, or burden of disease within a defined patient population or geographic area. Used in public health surveillance, population health management, and actuarial analysis to assess the rate and impact of illness, injury, or chronic conditions.

A quantified measure representing the rate or count of deaths within a defined patient population, time period, or clinical context. Used in public health reporting, hospital quality programs, and actuarial modeling to evaluate cause-specific or all-cause death rates and outcomes of care.

A numeric or coded data point derived from a magnetic resonance imaging study, representing a specific measured finding or diagnostic result. Used in clinical documentation, radiology reporting, and imaging analytics to capture quantitative outputs such as lesion size, signal intensity, or volumetric measurements.

Medicare Shared Savings Program — the CMS program established by the Affordable Care Act that enables Accountable Care Organizations to share in savings generated when they deliver high-quality coordinated care to Medicare fee-for-service beneficiaries at costs below a risk-adjusted expenditure benchmark. MSSP is the largest federal value based care initiative, with hundreds of ACO participants collectively serving millions of Medicare beneficiaries across multiple participation tracks with varying risk levels. Basic track participants begin with upside-only savings sharing before progressing to two-sided risk while Enhanced track participants accept immediate downside risk in exchange for higher savings sharing rates. MSSP quality reporting requirements include HEDIS clinical measures and CAHPS patient experience surveys, with minimum attainment thresholds that must be met before any shared savings distribution is received. Healthcare data teams build MSSP analytics pipelines that replicate CMS attribution methodology, calculate risk-adjusted benchmark expenditure, measure quality performance across required domains, project shared savings eligibility throughout the performance year, and produce CMS quality reporting submissions.

A boolean indicator identifying a health plan product that contracts with a selected subset of providers rather than the broadest available provider network, enabling lower premium costs in exchange for more limited provider choice by excluding providers with higher costs or lower quality performance. Narrow networks are designed to concentrate patient volume with the most efficient and highest-quality providers, generating lower average costs that allow health plans to offer more competitive premiums in individual and employer markets. The tradeoff of lower cost for limited choice makes narrow networks controversial — member satisfaction is lower when preferred providers are excluded, and access concerns arise when narrow networks lack sufficient specialists or geographic coverage. Healthcare data teams analyze narrow network composition by measuring quality and cost efficiency distributions of included versus excluded providers, modeling premium reduction potential from different network configurations, evaluating adequacy of the narrow network against CMS and state regulatory access standards, and tracking member utilization patterns to verify that narrow network design is achieving intended cost efficiency outcomes.

In quality measure design, an adverse clinical event or service that a measure aims to reduce rather than increase, such as inpatient admissions, emergency department visits, unplanned readmissions, or avoidable complications. For negative outcome measures, lower rates indicate better performance and the performance rate is calculated as the percentage of the denominator experiencing the negative event. Plan All-Cause Readmissions and Potentially Preventable Emergency Visits are examples of negative outcome HEDIS measures.

A member loyalty metric calculated from a single survey question asking how likely the member is to recommend their health plan or provider to a friend or family member on a scale of zero to ten, with promoters scoring nine or ten, passives scoring seven or eight, and detractors scoring zero through six. Net Promoter Score is calculated by subtracting the percentage of detractors from the percentage of promoters, producing a score ranging from negative 100 to positive 100. Health plan NPS scores typically range from negative 20 to positive 30 with higher scores indicating stronger member loyalty and advocacy. NPS is used as a leading indicator of member retention because high scores predict lower voluntary disenrollment rates. Healthcare data teams track nps_scr by plan product, member demographic segment, geographic market, and provider attribution to identify loyalty drivers and at-risk populations, correlate NPS with subsequent retention and disenrollment behavior, and measure the impact of member experience improvement initiatives on loyalty scores across the enrolled population.

A regulatory and accreditation standard requiring health plans to maintain a provider network with sufficient providers, specialists, and facilities to ensure timely access to covered services for enrolled members within defined geographic distance and appointment availability standards. Network adequacy is assessed by CMS, state insurance regulators, and NCQA using provider-to-member ratios, geographic access standards, and appointment availability measurements. Inadequate network adequacy findings can result in plan sanctions and enrollment restrictions.

An advanced CMS ACO model that offered higher shared savings rates and broader financial risk than the Medicare Shared Savings Program in exchange for accepting greater downside risk and participating in more innovative payment mechanisms including population-based payments. Next Generation ACO participants could receive monthly population-based payments rather than standard fee-for-service reimbursement, enabling more flexible care delivery including telehealth, home visits, and skilled nursing facility care beyond standard Medicare coverage. The model tested whether ACOs with more experience in value based care could thrive under more aggressive risk arrangements. CMS concluded the Next Generation ACO model in 2021 and transitioned participants into successor direct contracting and ACO REACH models. Healthcare data teams supporting next generation ACO participants built sophisticated population payment reconciliation systems that tracked actual utilization against population payment amounts, calculated quarterly settlement payments, and modeled risk sharing under the benchmark-based performance payment methodology.

Stores the discrete or free-text data point captured within a clinical documentation entry in EHR and clinical data repository systems. May represent a structured observation, score, or coded response linked to LOINC or SNOMED terminologies, supporting clinical decision support and outcomes analytics.

A numeric or coded data point associated with a surgical procedure, representing a specific measured outcome, count, or clinical finding. Used in surgical quality reporting, procedure utilization tracking, and outcomes analysis to quantify operative results, complication rates, or procedural volume metrics.

An exclusion criterion that health plans may choose to apply or not apply to a quality measure depending on their data availability and reporting strategy, allowing removal of members with certain conditions such as frailty, advanced illness, or dementia that may make the measure clinically inappropriate. Unlike required exclusions, optional exclusions give health plans discretion, but their consistent application must be documented and maintained across measurement years for audit validity.

A discrete measured or recorded data point associated with a clinical order, such as a dosage amount, test result numeric value, or service quantity captured in EHR and LIS systems. Stored in order detail and result tables within clinical data warehouses, used for quality measurement, clinical decision support, and outcomes analysis across Epic and Cerner.

A numeric or coded data point related to musculoskeletal care, representing a specific clinical measurement, functional score, or outcome associated with orthopedic treatment. Used in surgical outcomes tracking, rehabilitation monitoring, and specialty care analytics to quantify patient function and procedural results.

A HEDIS measure assessing the percentage of women 67-85 years old who suffered a fracture and who had either a bone mineral density test or a prescription for a drug to treat or prevent osteoporosis within 6 months after the fracture. OMW targets a high-risk population for recurrent fracture and hip fracture complications, and identification of members with fractures who did not receive post-fracture osteoporosis management represents a high-priority care gap in the Medicare Advantage elderly female population.

The measured clinical data point recorded for an ear, nose, and throat (ENT) specialty encounter or procedure. Captures quantitative or qualitative measurements such as hearing thresholds, sinus scores, or laryngoscopy findings used in otolaryngology diagnosis and treatment planning.

The unique alphanumeric identifier assigned to a specific patient treatment outcome record within a clinical or claims system. Used to link outcome data across encounters, billing records, and care management platforms to support longitudinal tracking of patient health results and program effectiveness.

A binary flag indicating whether a recorded patient treatment outcome is currently active and relevant for clinical or administrative use. A positive value confirms the outcome remains in effect for care planning, quality reporting, or utilization management, while a negative value marks it as resolved or retired.
