Mission Context

CMS and state partners relied on multiple legacy systems and manual workflows to manage Medicaid and CHIP program actions. Standards changed, application patterns aged, and fragmented tools made consistent review more difficult. theta. delivered across the modernization lifecycle: moving MACPro into CMS’s authorized cloud environment, strengthening quality through eAPD testing, and building OneMAC as the unified path forward.

Why it mattered

Program administration depends on consistent, traceable exchanges between states and CMS.

Program administration depends on consistent, traceable exchanges between states and CMS. Disconnected systems and manual intervention increase error risk, slow reviews, and make it harder to adapt when policy or reporting standards change.

The Challenge

Unify Medicaid oversight without interrupting active program work
1

Fragmented legacy workflows

Separate systems and processes created inconsistent experiences for state and federal users.

2

Manual, error-prone exchanges

Repeated intervention increased processing effort and made program actions harder to track.

3

Modernization without interruption

Cloud migration and new product delivery had to preserve access to active program work.

How theta. Delivered

A connected path from legacy platforms to OneMAC

Moved MACPro to CMS AWS GovCloud

theta. migrated the application from a commercial cloud environment and integrated it with CMS identity and access services.

2

Strengthened eAPD quality

theta. delivered software testing that improved release confidence for electronic advance planning document workflows.

3

Built OneMAC

theta. used Agile product delivery to advance the unified platform replacing fragmented Medicaid and CHIP workflows.

4

Connected delivery to operations

theta. aligned migration, testing, and product development so modernization could progress without losing program continuity.

Outcomes

Cloud, quality, and product modernization advanced together
theta. created a clearer, more secure modernization path across the platforms CMS uses to oversee Medicaid and CHIP program actions.

MACPro operating in CMS GovCloud

The application moved into the agency's authorized AWS environment with CMS identity integrations in place.

Stronger release confidence

Dedicated testing improved the quality and predictability of eAPD delivery.

A unified path through OneMAC

Agile product development advanced the phased replacement of disconnected legacy workflows.
