Modularity in Medicaid Management Information Systems (MMIS): Has the Silver Bullet Hit Its Target?

The US state Medicaid market is marred by legacy, monolithic Medicaid Management Information Systems (MMIS), which strain the government’s resources. Most initiatives to modernize these aging systems were accompanied by budget and timeline overruns in the past, and, in a few cases, lawsuits by vendors and the government. In such a scenario, CMS’ move to introduce modularity in MMIS was touted as the next big thing in US healthcare. A new modular MMIS was envisioned, which broke the siloed system into multiple modules and made the MMIS technologically superior, operationally more effective, and financially cheaper. While this is true, modularity has also introduced new complexities and challenges in the system.

In this viewpoint, we analyze modularity in MMIS and discuss its adoption among various states. We also look at how the vendor landscape has evolved due to modularity and what are some of the factors that could impact modularity in the future.
