coinsurance riskcoins_rsk

An assessment of the financial exposure or uncertainty associated with a coinsurance arrangement, considering member utilization patterns and plan liability. Used in actuarial modeling and underwriting to evaluate whether the defined cost-sharing percentage adequately distributes risk between the payer and member.

coinsurance routecoins_rte

The processing pathway through which a coinsurance obligation is calculated and applied during claims adjudication. Identifies whether the cost-sharing calculation follows standard medical, pharmacy, or facility benefit rules, ensuring the correct coinsurance percentage is applied based on service type.

coinsurance scorecoins_scr

A calculated value summarizing the relative coinsurance burden or cost-sharing performance for a member, plan, or provider group. Used in benefit analytics and population health reporting to rank and compare cost-sharing exposure across plan tiers, benefit designs, or member segments.

coinsurance sequencecoins_seq

A numeric value indicating the order in which a coinsurance rule is applied relative to other cost-sharing elements such as deductibles and copayments during claims adjudication. Ensures member liability is calculated in the correct sequence as defined by the benefit plan structure.

coinsurance severitycoins_sev

Indicates the severity level of a diagnosis or condition that determines the applicable coinsurance percentage on a claim. Higher severity tiers may trigger different cost-sharing rates under a member's benefit plan, affecting patient liability calculations.

coinsurance sexcoins_sex

Records the member's biological sex as it applies to coinsurance benefit determination. Used in health plan adjudication to validate gender-specific coverage rules and apply the correct cost-sharing percentage when processing claims for sex-linked services or benefits.

coinsurance sourcecoins_src

Source system or channel for coinsurance within Utilization processes in Healthcare implementations. Used for reporting, integrations, and downstream analytics.

coinsurance start datecoins_start_dt

The effective date on which a member's coinsurance obligation begins under a specific benefit plan or policy period. Used in claims adjudication and member enrollment systems to determine when the cost-sharing percentage applies to covered medical services.

coinsurance start timecoins_start_tm

The specific time of day at which a coinsurance rule or benefit period becomes effective. Used in health plan systems to precisely establish when a member's cost-sharing obligation activates, particularly relevant for same-day benefit changes or inpatient admission timing.

coinsurance statecoins_st

The U.S. state or territory associated with a coinsurance benefit rule or member policy. Used in health plan enrollment and claims systems to apply state-mandated cost-sharing requirements and determine jurisdiction-specific coinsurance rates for covered services.

coinsurance statuscoins_sts

A lifecycle status field stored as coins_sts that reflects the current processing state of a coinsurance obligation within pharmacy and claims systems, such as Pending, Applied, Waived, or Reversed. Used in PBM platforms and benefit administration systems to manage cost-share workflows and support member financial reporting.

coinsurance strengthcoins_str

Captures the drug concentration or dosage strength associated with a pharmacy benefit that carries a coinsurance obligation. Used in pharmacy claims processing to apply the correct cost-sharing percentage based on formulary tier rules tied to specific drug strengths.

coinsurance subtotalcoins_subtot

A partial sum of coinsurance amounts owed by a member before final adjustments, credits, or additional charges are applied. Used in claims financial reporting to break down member cost-sharing liability across multiple service lines or benefit categories within an explanation of benefits.

coinsurance system identifiercoins_sys_id

A system-generated unique key assigned to a specific coinsurance record within a health plan or claims processing platform. Used to track, reference, and reconcile coinsurance configurations across adjudication engines, member portals, and benefit administration systems.

coinsurance targetcoins_tgt

Identifies the specific benefit category, service type, or claim line to which a coinsurance percentage is directed. Used in health plan benefit design systems to map cost-sharing rules to targeted covered services such as specialist visits, imaging, or inpatient stays.

coinsurance taxonomy codecoins_tax_cd

The NUCC provider specialty taxonomy code associated with a coinsurance rule, identifying the rendering provider's specialty classification. Used in claims adjudication to apply the correct cost-sharing percentage based on the type of provider delivering the covered service.

coinsurance temperaturecoins_temp

Records a patient's body temperature measurement linked to a clinical encounter where coinsurance cost-sharing applies. Used in integrated clinical-financial data systems to associate vital sign data with the claim event that triggers a member's coinsurance obligation.

coinsurance termination datecoins_term_dt

The date on which a member's coinsurance benefit obligation ends under a specific plan or policy. Used in health plan enrollment and claims adjudication systems to ensure cost-sharing rules are no longer applied after coverage termination or benefit period expiration.

coinsurance timecoins_tm

The specific time of day associated with a coinsurance event, such as when a claim service was rendered or a benefit rule was evaluated. Used in claims processing systems to establish precise temporal context for cost-sharing calculations and audit trails.

coinsurance timestampcoins_ts

System timestamp for coinsurance within Eligibility processes in Healthcare implementations. Used for reporting, integrations, and downstream analytics.
