Modernizing a Legacy Disbursement Hub to Power High-Volume Healthcare Payments
High-volume healthcare payment platforms can’t afford performance bottlenecks, fragile integrations, or legacy constraints. In this case study, discover how HealthAsyst helped a leading U.S. healthcare payment facilitator modernize a mission-critical disbursement hub, unlocking scale, speed, and reliability without disrupting ongoing operations.
The Need
As transaction volumes grew into the billions, the customer’s legacy disbursement hub, central to insurer, hospital, and government payment workflows, began to limit scalability and agility. New partners needed faster integrations, end users expected flexible payment options, and internal teams required stable environments to develop and release features with confidence.
To support continued growth, the platform needed modernization without risking downtime, compliance, or business continuity in a highly regulated healthcare ecosystem.
The Challenge
The platform faced multiple compounding challenges:
- A legacy Windows-based architecture with limited in-house expertise
- Severe performance issues, with 3,000+ payment vouchers taking over 5 hours to process
- Fragmented APIs with multiple versions and no centralized documentation
- No clearly defined development, sandbox, or production environments
- Lack of automated testing, resulting in frequent defects and redeployments
- Legacy code vulnerabilities creating security and compliance risks
Together, these issues slowed partner onboarding, strained operations, and threatened the platform’s ability to scale.
