Scalable APIs for StarHealth with CMS Open Payments and GCP

Managing CMS Open Payments data presented multiple challenges for StarHealth. The platform required scalable APIs capable of:

• Ingesting large volumes of financial transaction data, including payments, ownership interests, and transfers of value.
• Supporting real-time analytics, dynamic dashboards, and customizable reports.
• Generating alerts for unusual patterns to strengthen compliance monitoring.
• Scaling to meet surges in traffic during regulatory deadlines.
• Enforcing strict compliance with HIPAA and GDPR for data security and privacy.

The project demanded a robust, cloud-native architecture with both reliability and flexibility.

NextGen developed and deployed a secure, scalable API system on Google Cloud Platform (GCP) to integrate CMS Open Payments into StarHealth’s ecosystem.

• Established a RESTful API integration with CMS Open Payments to ingest financial transaction records.
• Synchronized data in real time, ensuring providers and administrators had immediate access.

Real-Time Data Processing with Google Cloud Dataflow

• Deployed Google Cloud Dataflow to clean, transform, and enrich ingested data.
• Supported both batch and streaming pipelines to handle historical data loads and live updates.

Centralized Data Storage in BigQuery

• Leveraged Google BigQuery for scalable, high-performance storage.
• Enabled advanced querying on payments by physician, specialty, or region.

Secure API Gateway

• Implemented Google Cloud Endpoints as an API gateway with authentication, rate-limiting, and monitoring.
• Provided secure access for both internal developers and external partners.

Custom Dashboards in Looker Studio

• Built interactive dashboards with Looker Studio, enabling customizable visualizations.
• Supported filters for compliance monitoring, regional payment analysis, and trend identification.

Real-Time Alerts with Firebase Cloud Messaging

• Integrated Firebase Cloud Messaging to trigger alerts for irregular transactions or compliance risks.
• Provided instant notifications to regulatory teams for proactive action.

Scalable Cloud Infrastructure

• Deployed the system on Google Kubernetes Engine (GKE) for auto-scaling during traffic surges.
• Maintained consistent performance during high-volume regulatory reporting periods.

Security and Compliance

• Applied Google Cloud Key Management Service (KMS) for encryption in transit and at rest.
• Enforced role-based access with Firebase Authentication.

Ensured end-to-end compliance with HIPAA and GDPR.

The CMS Open Payments integration transformed StarHealth’s ability to manage financial compliance data:

• 50% faster search times, with immediate access to payment records by physician or organization.
• 30% improvement in compliance monitoring, supported by automated alerts and anomaly detection.
• Millions of daily records processed, with queries reduced from hours to seconds via BigQuery.
• 1 million+ API requests per day supported, with performance maintained during peak usage.
• 40% increase in dashboard engagement, as users visualized complex data in real time.
• 25% rise in partner adoption, driven by secure external API access.
• 35% increase in user trust, following strong compliance and encryption measures.

Healthcare compliance requires transparent, real-time access to financial transaction data. By integrating CMS Open Payments with scalable APIs and cloud-native architecture, StarHealth delivered a platform that improved compliance monitoring, reduced reporting delays, and increased trust across the industry. The project highlights how combining GCP services with secure APIs enables healthcare organizations to meet regulatory requirements while expanding value for users and partners.

Healthcare organizations managing compliance and reporting workflows benefit from scalable APIs and real-time data pipelines. NextGen builds cloud-native systems that integrate regulatory data securely while ensuring compliance with HIPAA and GDPR.
