The Customer

The client is a Fortune 500 Healthcare company with more than $21bn in annual revenue and more than 77,000 employees supporting client operations in 100 countries and 750 global locations. The customer supports US states and Healthcare providers with Medicaid Management Information Systems (MMIS). An MMIS is composed of many functional components like Provider and Member enrollment, claims processing and payment systems with high end reporting solutions working together to pay Medicaid claims to active providers. In addition it contains robust reporting capabilities and is required to interface with outside entities while also tracking correspondence and communications.


The customer had an existing legacy system of 30 different applications with this product, some of which were COTS products like DocFinity and xPression. This disparate nature of the system posed significant challenges to efficiency and interoperability. The system needed to process around 4 million claims a month that would result in provider payments of $400mn. In addition, the system needed to maintain and enroll approximately 40000 providers and determine eligibility of 1 million recipients.

From an architectural standpoint the system needed to be designed to process up to 100,000 claims in 2 hours and determine eligibility of 5000 members in 30 minutes.


Infinite’s analysts studied the requirements of the system and recommended a product that was built on IBM WebSphere suite. With the margin for error being virtually zero, the product would need robust architecture to support the functional demand. Service Oriented Architecture (SOA) was used to build this product, keeping needs of the stakeholders of the system in mind. Blaze Advisor Rules Engine was chosen because it enabled changes in rules to be made directly in the database, rather than in program code. This would reduce the time taken to make the change in rules that determined the processing logic.


Infinite’s robust solution had measurable business impact. Once the product was built, it reduced the cost of development and implementation. Similarly, time of development, customization and implementation for the client was brought down once the product was deployed. A key business advantage was the ability to quickly incorporate the change in Healthcare regulations.

The scalable application with high availability in a clustered environment with multiple node support could reduce the processing time of claims and payment for recipients or providers.
