Automating Clinical Validation in Claims Adjudication: An NLP/LLM Systems Approach

Abstract

Healthcare claims adjudication suffers a lot of challenges in its operations because of manual clinical validation processes that use huge resources and yield inconsistent results when applied to different populations of reviewers. The use of Natural Language Processing and Large Language Models to automate clinical validation offers a transformational potential for payment integrity activities in payer organizations. Domain-adapted models of language models, such as BioBERT and ClinicalBERT, exhibit advanced performance in the task of clinical entity detection, medical terminology comprehension, and documentation pattern reasoning that is typical of real-world healthcare delivery. The introduction of the implementation strategies that focus on the gradual implementation, human-AI interaction, and ongoing quality control allows integrating the novel approach into the existing adjudication processes without deteriorating the quality of the results that are needed to comply with the regulations. The deployed systems are shown to have significant gains in processing efficiency, consistency of decisions, and the productivity of reviewers in comparison to traditional manual validation techniques. The features of enhanced explainability create transparent justifications to support appeals management and audit requests and establish trust among the clinical staff. The technology can resolve the underlying capacity issues of payer organizations by facilitating the processing of greater claim volumes without similarly large projections of staffing. Financial gains are attained in the form of lower processing fees, lower rate of appeals, and reduced adjudication time, which enhances the satisfaction of stakeholders. The development of such systems proceeds via the increased training data, improved architectures, and experience of operation that brings the ability to solve more and more complicated validation problems. The smart fusion of the sophisticated computational systems with human clinical knowledge generates validation workflows that will reach performance levels that are not feasible by either of the preceding methods.
