Optimizing Health Insurance Claims Processing: The Role of Clinical Documentation Improvement (CDI)

Background and Objectives: Clinical Documentation Improvement (CDI) programs have been identified as a financial risk reduction strategy and are becoming increasingly important in payer-provider alignment. This study aimed to evaluate the effect of CDI on insurance claim denials in the context of the healthcare sector in Saudi Arabia and the Vision 2030 healthcare transformation plan. Methods: A cross-sectional study of secondary data from two public healthcare facilities in Eastern Saudi Arabia. A total of 203 insurance claim denials (2023–2024 data) were analyzed. Denial reasons, CDI implementation, and patient characteristics were the study variables. Results: Among the rejected insurance claims, 52.7% of the denials were due to policy, declaration, and billing issues, and 47.3% were due to documentation issues. Denial reasons were significantly different between the two study hospitals. Documentation-related denials were significantly higher in the absence of CDI implementation (86.2%), whereas policy and billing issues were predominant in the hospital with CDI implementation (92%). The absence of CDI implementation was strongly associated with documentation-related denials (OR=73.07). Female patients had lower odds of insurance claim denials (OR=0.055, p<0.001). Diagnosis was significantly associated with denial reasons (χ²=119.152, p<0.001). Conclusion: CDI implementation is associated with a substantial reduction in documentation-related insurance claim denials and policy and billing issues. This study highlights the role of documentation in financial risk reduction and the importance of CDI implementation in healthcare facilities in the context of the healthcare sector in Saudi Arabia and the Vision 2030 healthcare transformation plan.
