The portion of written premium revenue that has been earned by the insurance company through the passage of time as coverage has been provided to policyholders, calculated by prorating written premiums over the coverage period. Earned premium is the appropriate revenue measure for matching against incurred claims in medical loss ratio calculations, as it represents premiums for coverage that has already been provided rather than premiums collected for future coverage periods. Earned premium calculations are fundamental to health plan GAAP and statutory financial reporting.

The unique account identifier linked to a coverage effective date record within member enrollment and benefits administration systems. Used to track when health plan coverage becomes active for a member, supporting claims eligibility verification, enrollment reconciliation, and benefit period management across payer systems.

The expense amount associated with initiating or administering coverage as of a specific effective date within a health plan. Used in enrollment and premium billing workflows to capture costs tied to coverage activation, retroactive adjustments, and benefit period financial reconciliation for member accounts.

A boolean indicator identifying that a healthcare claim was submitted electronically using a HIPAA-compliant standard transaction format rather than a paper claim form. The Health Insurance Portability and Accountability Act mandates electronic submission for most Medicare and Medicaid claims, and commercial payers strongly incentivize electronic submission through faster processing times and lower administrative fees. Electronic claims are transmitted in the X12 837P format for professional claims, 837I format for institutional claims, and 837D format for dental claims. Electronic submission through clearinghouses enables claim validation before payer submission, reducing rejection rates and accelerating payment. Healthcare data teams track elec_clm_ind to measure electronic submission rates by payer and facility, calculate administrative cost savings from paper-to-electronic conversion, identify remaining paper claim volumes by payer that could be converted to electronic submission, and benchmark electronic submission rates against industry standards.

The electronic transmission of healthcare claim payment funds directly from a health insurance payer bank account to a provider bank account, replacing paper check payments and enabling faster, more accurate cash management. The HIPAA Administrative Simplification provisions require payers to offer electronic funds transfer to providers upon request using the CCD+ format. Electronic funds transfer is paired with the HIPAA 835 electronic remittance advice transaction to provide both the payment and the detailed explanation of how each claim was processed in a standardized electronic format. Healthcare organizations that adopt EFT and ERA eliminate check handling costs, reduce payment posting errors, and accelerate cash availability. Healthcare data teams track EFT adoption rates by payer, measure the cost reduction from eliminating paper check processing, and reconcile EFT deposits against 835 remittance data to ensure all expected payments are received and accurately posted.

The process of confirming that a patient is enrolled in and actively covered by a health insurance plan on the date of service, using real-time electronic inquiry through HIPAA 270/271 transactions or payer web portals. Eligibility verification confirms the member active enrollment status, coverage effective and termination dates, plan type and benefit structure, primary care physician assignment for HMO plans, and referral requirements. Eligibility errors are among the most common causes of claim denials, generating significant rework costs and payment delays. Industry best practice recommends verifying eligibility for all patients within 48 hours of the scheduled service and again on the date of service for high-volume payers. Healthcare data teams build eligibility verification analytics that track real-time verification rates by payer and service type, measure eligibility denial rates as a quality indicator, and calculate the revenue impact of eligibility-related denials to justify investment in automated eligibility verification technology.

The unique account identifier assigned to track claims and financial transactions associated with emergency care services rendered to a member. Used in medical claims processing and care management systems to link emergency department visits, urgent interventions, and associated costs to a specific member benefit account.

The total dollar amount paid or incurred for emergency department or urgent care services, captured at the claim or encounter level. Includes facility fees, physician services, and ancillary charges billed under emergency revenue codes in medical claims data.

The number of emergency department visits per 1,000 member years for a health plan enrolled population, used as a utilization quality and financial metric indicating access to appropriate primary and urgent care alternatives. High ED visit rates relative to benchmarks suggest inadequate access to after-hours primary care, insufficient urgent care network coverage, or member health literacy gaps driving unnecessary ED utilization. ED visit rate reduction through improved care access and member education is a cost-effective quality improvement intervention.

Claims-like records submitted by Medicaid managed care organizations and Medicare Advantage plans to state Medicaid agencies and CMS documenting all healthcare services provided to enrolled members, used for risk adjustment, quality measurement, program oversight, and rate setting. Encounter data completeness and accuracy are subject to CMS and state audit requirements, with incomplete encounter data submission resulting in risk adjustment payment penalties and increased regulatory scrutiny of plan financial and quality reporting.

The unique account identifier assigned to endocrinology specialty services, including diabetes, thyroid, and hormonal disorder care. Used to track and reconcile endocrinology-related claims, referrals, and patient encounters across billing and clinical systems.

The total dollar amount paid or incurred for endocrinology specialty services, including consultations, hormone testing, and treatment for conditions such as diabetes, thyroid disorders, and metabolic diseases. Captured at the claim or encounter level in medical cost data.

The unique identifier assigned to a discrete episode of care, representing all services delivered for a specific condition or procedure within a defined timeframe. Used in value-based care analytics to group related claims and track total cost across care settings.

The remaining unpaid dollar amount associated with all services within a defined episode of care after payments, adjustments, and credits have been applied. Used in revenue cycle management to monitor outstanding financial obligations tied to condition-specific care episodes.

The total gross charges submitted to the payer for all services rendered within a defined episode of care for a specific condition or procedure. Represents the sum of all claim line billed amounts before contractual adjustments, denials, or patient responsibility are applied.

The total allowed or paid dollar amount for all healthcare services delivered within a defined episode of care for a specific clinical condition or procedure. Used in value-based payment models to evaluate provider efficiency and total cost of care across the care continuum.

The count or rate at which discrete care episodes occur for a specific condition or procedure within a defined population and time period. Used in utilization management and population health analytics to identify high-frequency conditions driving medical cost and care variation.

The unique account identifier assigned to durable medical equipment, prosthetics, orthotics, or supplies provided to a patient or facility. Used to track equipment-related billing, inventory, and claims submissions under HCPCS codes in DME and ancillary service records.

The total dollar amount paid or incurred for durable medical equipment, prosthetics, orthotics, or medical supplies. Captured at the claim level using HCPCS billing codes and used in cost analysis to evaluate DME expenditures across member populations or benefit categories.

The unique account identifier assigned to a clinical evaluation or assessment service, such as an evaluation and management visit, diagnostic workup, or functional assessment. Used to track and reconcile evaluation-related billing and encounters across healthcare systems.
