Quality

The CMS summary quality rating assigned to Medicare Advantage and Part D prescription drug plans on a scale of one to five stars reflecting plan performance on clinical quality measures, member experience surveys, and administrative efficiency metrics. Star ratings are calculated annually from HEDIS clinical measures, CAHPS member experience surveys, Health Outcomes Survey functional status measures, and CMS administrative measures covering appeals, complaints, and call center performance. Plans earning four or more stars qualify for quality bonus payments that significantly increase capitation revenue and enable enhanced benefits for members. Five-star plans receive the highest bonus and can market year-round outside normal enrollment periods. Healthcare data teams build star ratings analytics pipelines that calculate measure-level performance rates, apply CMS cut points to determine star levels for each measure, weight measures according to CMS methodology to calculate domain and overall star ratings, and project final star ratings throughout the measurement year to guide quality improvement prioritization.

The year-over-year change in a health plan CMS Star Rating score at the overall, summary, or individual measure level, used to assess quality program effectiveness, benchmark plan performance trajectory against competitor plans, and project future payment implications of current quality improvement investments. Star rating trends are a primary KPI for Medicare Advantage quality programs because multi-year improvement trajectories affect plan reputation, enrollment growth, and long-term financial performance.

The monetary or numeric amount reflected on a patient account statement summarizing charges, payments, adjustments, and outstanding balances for a defined billing period. Used in revenue cycle management systems to communicate financial obligations to patients and support collections and payment plan processing.

A quality measure tracking the proportion of days covered for statin therapy in members who had an acute myocardial infarction and were discharged on statin medication, used to assess secondary prevention therapy adherence in a high-risk cardiovascular population. Post-MI statin adherence is associated with significantly reduced risk of recurrent MI, stroke, and cardiovascular death, making this a high-priority medication adherence quality measure in both commercial and Medicare Advantage health plan quality programs.

A HEDIS measure assessing the percentage of members 21-75 years old with clinical atherosclerotic cardiovascular disease or an LDL-C of 190 mg/dL or higher who were dispensed at least one statin medication of any intensity during the measurement year. STP evaluates primary and secondary cardiovascular prevention through statin prescribing and is distinguished from SPC which focuses on high-intensity statin use in members with established cardiovascular disease events.

A HEDIS measure assessing the percentage of members 21 years and older who were discharged alive after a coronary artery bypass graft, percutaneous coronary intervention, or had evidence of cardiovascular disease and received a statin medication of any intensity. SPC is included in CMS Star Ratings and represents a high-yield quality improvement intervention because statin therapy has strong clinical evidence for secondary cardiovascular event prevention and most members with qualifying diagnoses are candidates for therapy.

The numeric measurement representing the duration or a specific metric of an inpatient hospital stay, such as length of stay in days, acuity score, or cost per stay. Used in utilization management, case mix reporting, and payer contract analysis to evaluate inpatient resource consumption and efficiency.

The numeric concentration or potency of an active pharmaceutical ingredient in a medication formulation, expressed in units such as mg, mcg, or mg/mL. Captured in pharmacy and medication management systems to ensure accurate prescribing, dispensing, and clinical decision support for dosing verification.

The numeric or coded result associated with a diagnostic imaging examination or clinical research study, such as a radiology read score, imaging finding severity rating, or protocol-specific measurement. Used in radiology information systems and clinical data repositories to quantify and track diagnostic study outcomes.

An aggregated or rolled-up numeric measure derived from detailed clinical, financial, or operational records to provide a high-level snapshot of patient health status, account activity, or population metrics. Used in reporting dashboards, care management platforms, and executive analytics to support decision-making.

Clinical information obtained from sources other than administrative claims data, such as electronic health record extracts, laboratory result feeds, provider attestations, or pharmacy data feeds, used to identify numerator events or exclusions in quality measure calculations that may not be captured in standard claims. Supplemental data submission requires NCQA certification and auditable source documentation linking each supplemental event to a verifiable clinical record.

A flag indicating that a surgeon's involvement in a specific procedure or patient case is restricted from general visibility due to privacy, legal, or sensitivity requirements. Controls attribution of surgical services in operative documentation, claims data, and care coordination records while maintaining appropriate audit trails.

A flag indicating that a surgeon's record has been logically removed from active provider rosters within surgical scheduling or clinical documentation systems. Prevents assignment of new cases while preserving historical operative records for compliance, credentialing audit, and outcomes reporting purposes.

A flag identifying a specific surgeon as the primary or attending operative clinician responsible for a surgical procedure. Used in operative reporting, claims adjudication, and credentialing systems to distinguish the lead surgeon from assistants or co-surgeons when multiple clinicians participate in a procedure.

The age of a patient or respondent at the time a healthcare satisfaction or outcomes survey was administered. Used in patient experience analytics and population health reporting to segment survey results by age cohort, identify demographic response patterns, and support CAHPS or similar standardized reporting requirements.

The maximum reimbursable dollar amount associated with administering a patient survey instrument or health assessment tool under a specific payer contract or program. Used in value-based care and quality incentive programs to capture approved compensation for survey-linked outreach and patient engagement activities.

The total monetary value associated with a patient survey activity, including costs or reimbursements tied to survey administration, outreach, or incentive programs. Used in quality and value-based program accounting to track financial transactions linked to patient feedback collection and health outcomes measurement initiatives.

Identifies the user who authorized a patient satisfaction or clinical survey instrument for distribution. Captures the approving staff member's credentials in quality management workflows, ensuring accountability for survey content before deployment to patients or care teams.

Records the clock time a patient physically arrived at a care facility during the encounter linked to a satisfaction or outcomes survey. Used in patient experience analytics to correlate wait times, throughput efficiency, and service quality scores reported in survey responses.

Records the calendar date a patient arrived at a care facility for the encounter associated with a satisfaction or outcomes survey. Used in patient experience reporting to align survey responses with specific visit dates and measure care quality across time periods.
