Trendsic Case Study

ARAMIS & OARS Modernization Unifies Louisiana’s Public Health Billing

Trendsic integrated two aging state billing systems — ARAMIS and OARS — into one unified web application, modernizing Medicaid and Medicare billing and accounts receivable for Louisiana’s community mental health and addictive disorder clinics and significantly improving data management statewide.

Trendsic system modernization for Louisiana Department of Health and Hospitals

Client & Industry

The Louisiana Department of Health and Hospitals is the state agency responsible for overseeing public health programs, community mental health services, and addictive disorder treatment clinics across Louisiana. Managing Medicaid and Medicare billing for this network of clinics requires robust, accurate, and interconnected systems.

At this point, the Department was relying on two separate legacy platforms — ARAMIS (Accounts Receivable and Management Information System) and OARS (On-line Accounts Receivable System) — to handle electronic accounts receivables and government health billing.

Trendsic was contracted to modernize and integrate both systems into a single, efficient platform — a critical government IT modernization for one of Louisiana’s most essential public health agencies. See how Trendsic serves government clients across Louisiana.

The Challenge

Outdated, fragmented billing systems were creating inefficiencies across Louisiana’s statewide network of community mental health and addictive disorder clinics — slowing Medicaid and Medicare transactions and impairing data management.

Challenge 1

Outdated Legacy Systems

Both ARAMIS and OARS operated on aging platforms with limited capabilities, constraining the Department’s ability to scale and adapt to evolving state health IT requirements.

Challenge 2

Fragmented Billing Processes

Running separate billing systems for mental health and addictive disorder clinics introduced redundancy and inefficiencies into Medicaid and Medicare billing workflows across the state.

Challenge 3

Inadequate Data Warehousing

The existing data warehousing infrastructure lacked the capacity and accuracy needed to support effective statewide billing operations, hindering reliable reporting and financial oversight.

The Solution

Trendsic developed a unified web application that seamlessly integrated ARAMIS and OARS, consolidating billing operations and modernizing data management for the Louisiana Department of Health and Hospitals.

Capability 1

Streamlined Billing & Accounts Receivable

Trendsic built a consolidated system serving both community mental health and addictive disorder clinics, with enhanced electronic Medicaid and Medicare billing processes replacing the two fragmented legacy workflows.

Capability 2

Advanced Data Warehousing

Upgraded data warehouse capabilities enabled efficient statewide billing and data management, with integrated data uploads from the new unified system providing better consolidation and accuracy across all participating clinics.

Capability 3

Phased Retirement of Redundant Modules

Outdated ARAMIS modules were gradually phased out as their functions were transferred to the new platform, ensuring a smooth transition with minimal disruption to departmental operations throughout the migration.

This modernization project reflects Trendsic’s expertise in government software integration and state health IT — delivering complex system migrations with minimal disruption to critical public services.
