This paper explores the utilization of Pega Decisioning capabilities to personalize patient communication and resolve disputes effectively within healthcare organizations. By integrating patient data, treatment history, and dispute resolution workflows, Pega Decisioning enables tailored communication strategies and resolutions based on individual patient needs and preferences. The study employs a mixed-methods approach, combining quantitative data analysis with qualitative case studies, to assess the impact of Pega Decisioning on patient satisfaction and operational efficiency. The findings demonstrate significant improvements in personalized communication, reduced dispute resolution times, and enhanced patient engagement, suggesting that advanced decision management tools can transform healthcare communication and dispute resolution processes.
