Claims data plays a vital role in the landscape of healthcare information, providing insights into patient care, provider performance, and healthcare costs. It is generated every time healthcare providers submit billing requests to insurers, offering a wealth of information about interactions between patients, healthcare professionals, and payers. This data encompasses various standardized codes and details that are crucial for analyzing healthcare utilization, costs, and outcomes.

As organizations increasingly leverage claims data for research and operational purposes, understanding its types, advantages, and challenges becomes essential. Combining claims data with other real-world data sources, such as electronic health records or registries, enhances the depth and accuracy of insights, enabling more informed decision-making. For example, exploring innovative applications like virtual reality in medicine perspectives and features can further enrich healthcare research.

This article delves into the different types of claims data, their respective uses, and the benefits and limitations associated with their employment in healthcare analysis. It also discusses best practices for protecting patient privacy and highlights how organizations can access and connect claims data effectively through platforms like Datavant.

Different Types of Claims Data

Claims data can be categorized into two main types, each originating from distinct sources and serving different purposes in healthcare analysis.

Open Claims

Open claims refer to healthcare transactions that are still in progress or awaiting final resolution. These include services that have been rendered but are under review, pending adjudication, or reimbursement. Because they are not yet finalized, open claims tend to reflect more current activity, making them suitable for real-time monitoring and rapid insights.

Healthcare facilities generate open claims by submitting clinical data such as procedures, diagnoses, and encounters, which provides a snapshot of ongoing patient interactions. This type of data is particularly useful when capturing large volumes of patient activity, such as in marketing or operational contexts where some data completeness can be tolerated. Their real-time nature allows organizations to respond quickly to emerging trends or issues.

Closed Claims

In contrast, closed claims are those that have undergone review, processing, and final determination of payment. Once a claim is resolved—either approved for reimbursement or denied—it is considered closed. This dataset offers a comprehensive view of healthcare services that have been fully processed, reflecting completed patient encounters and associated costs.

Closed claims are predominantly generated by insurers and serve as a reliable source for assessing healthcare utilization, costs, and outcomes over a specified period. Due to the processing time involved, this data typically becomes available weeks or months after the services are provided, making it more suitable for retrospective analyses and comprehensive studies.

Advantages and Disadvantages of Claims Data for Healthcare Analysis

While claims data provides a rich resource for understanding healthcare utilization and outcomes, it also presents certain challenges that organizations must navigate. Recognizing these benefits and limitations is key to leveraging claims data effectively.

Advantages of Claims Data

• Standardization and Streamlined Processing: Claims data adheres to structured templates with uniform codes such as ICD-10 for diagnoses and CPT for procedures. This standardization simplifies data processing, enhances consistency, and accelerates analysis workflows.
• Large and Diverse Sample Sizes: The extensive volume of claims data allows for the study of rare conditions and diverse patient populations, increasing the statistical power of research and supporting robust findings.
• Tracking Patient Journeys Across Providers and Payers: Claims data from multiple sources enables organizations to follow patient care pathways across various healthcare settings and insurance plans, giving a holistic view of patient experiences.
• Cost-Effective Data Utilization: Since claims data is routinely collected for billing purposes, it is readily available, reducing the need for additional data collection efforts and associated costs.
• Structured and Privacy-Ready: Fully structured datasets facilitate de-identification processes, ensuring patient privacy while maintaining data utility for research.

Disadvantages of Claims Data

• Limited Clinical Detail: Claims data often lack detailed clinical information such as physician notes, lab results, or imaging data, which restricts the depth of clinical analysis and outcome assessment.
• Fragmentation and Integration Challenges: Combining claims data from different payers and providers can be complex due to data silos and inconsistent formats, hindering comprehensive patient profiling.
• Incomplete Healthcare Journey: Certain interactions, like non-billable services or informal care, may not be captured, leaving gaps in the patient’s complete healthcare history.
• Limited Insight into Utilization and Appropriateness: While claims indicate when care was provided, they do not necessarily reflect how often or whether treatments were appropriate for the patient’s condition.
• Exclusion of Uninsured and Cash Payments: Patients without insurance and those paying cash are often omitted, which can skew analyses and limit representativeness.
• Missing Certain Data Types: Information such as laboratory results, imaging, and genetic data are frequently absent, restricting the ability to analyze specific diseases or patient subgroups. Integrating claims data with sources like electronic medical records (EMRs) can address these gaps, offering a more comprehensive view.

Practical Uses of Claims Data in Healthcare

Combining claims data with other real-world data sources opens numerous opportunities for advancing healthcare research and improving patient outcomes. From evaluating treatment effectiveness to disease monitoring, claims data underpins many critical applications.

• Comparative Effectiveness Research: By analyzing real-world patient data, organizations can assess how different treatments perform outside controlled trials. For instance, evaluating the effectiveness of various antihypertensive medications in reducing cardiovascular events can inform clinical decisions. Accessing detailed data through platforms like artificial intelligence in healthcare pharmaceuticals and sports enhances such analyses.

• Health Economics and Outcomes Research (HEOR): This field evaluates the economic impact of healthcare interventions, guiding policy and reimbursement decisions. For example, analyzing claims from a large cohort can reveal the cost savings associated with new diabetes management programs, supporting broader adoption.

• Disease Surveillance and Epidemiology: Claims data enables monitoring disease trends across populations, essential during outbreaks or for vaccine effectiveness studies. During flu seasons, tracking diagnosis and treatment patterns helps public health officials allocate resources effectively. In long-term vaccine studies, linking various data sources, including claims, supports assessment of sustained vaccine efficacy.

• Patient Adherence and Treatment Compliance: Understanding medication refill patterns and gaps in care helps identify patients who may need additional support. For example, linking claims and social determinants of health data can reveal barriers like transportation issues, prompting targeted interventions.

• Predictive Analytics and Risk Stratification: Integrating clinical data with claims enhances the ability to predict patient risks, such as hospital readmission. This proactive approach facilitates personalized care and resource allocation, ultimately improving outcomes.

Protecting Privacy and Ensuring Data Security

Handling claims data necessitates strict privacy protections to safeguard patient confidentiality and comply with regulations like HIPAA. Effective measures include:

• De-identification and Anonymization: Removing personally identifiable information (PII) while preserving data utility allows organizations to conduct research securely.
• Access Controls and Secure Sharing: Limiting data access to authorized personnel and using encrypted channels ensure data remains protected during transfer and storage.

Platforms like virtual reality in medicine perspectives and features demonstrate how technological advances are balancing innovation with privacy considerations, emphasizing responsible data management.
