Multi-Specialty Hospital Network
OIC-powered integration unifying ERP, HIS, and billing across 6 hospitals.
All case studiesA multi-specialty hospital network operating 6 hospitals across Tamil Nadu, Kerala, and Karnataka engaged Cydez Technologies to build a unified integration architecture connecting disparate clinical and administrative systems. Each hospital ran its own hospital information system (HIS), pharmacy management system, laboratory information system, and billing platform — all from different vendors with no interoperability.
A patient visiting two hospitals within the network had two separate medical records with no cross-referencing. Insurance claim rejections ran at 18% due to ICD-10 coding errors, missing documentation, and billing discrepancies between departments. Monthly billing reconciliation between clinical departments and the finance team consumed 5 days of effort. The CFO had no real-time visibility into revenue cycle performance across the 6 facilities.
Cydez deployed Oracle Integration Cloud (OIC) as the central integration hub, connecting each hospital's HIS with a unified Oracle ERP Cloud instance for financials and procurement. HL7 FHIR APIs were built to create a master patient index enabling a single patient record across all 6 hospitals. Automated billing workflows with ICD-10 code validation at the point of care reduced claim rejections. A real-time revenue cycle management dashboard built on Oracle Analytics Cloud gave the finance leadership visibility into admissions, billing, collections, and outstanding claims across all facilities.

A multi-specialty hospital network operating 6 hospitals across South India ran separate HIS, billing, pharmacy, and ERP systems at each facility. Patient data was siloed — a patient visiting two hospitals had two separate records. Billing reconciliation between departments took 5 days per month, and insurance claim rejections ran at 18% due to coding errors and missing documentation.
Cydez deployed Oracle Integration Cloud as the central integration hub, connecting each hospital's HIS with a unified Oracle ERP Cloud instance for financials and procurement. HL7 FHIR APIs enabled a master patient index across all 6 hospitals. Automated billing workflows with ICD-10 code validation reduced claim rejections, and a real-time revenue cycle dashboard gave the CFO visibility across all facilities.
How we delivered this project
Discovery
Audited all 6 hospitals over 8 weeks. Mapped HIS vendor APIs, data models, and HL7 message capabilities at each facility. Documented billing workflows, insurance panel requirements, and ICD-10 coding practices. Identified the top 20 claim rejection reasons.
Design
Designed the OIC integration architecture with canonical data models for patient, encounter, and billing data. Created the HL7 FHIR-based master patient index specification. Designed the Oracle ERP Cloud configuration for multi-facility financial consolidation. Planned the revenue cycle dashboard on OAC.
Development
Built OIC integration flows connecting 6 HIS systems using HL7 FHIR and REST APIs. Developed the master patient index with probabilistic matching algorithms. Configured Oracle ERP Cloud with multi-facility chart of accounts. Built automated ICD-10 validation logic and insurance claim submission workflows.
Launch
Deployed facility-by-facility over 12 weeks. Each facility required HIS API testing, data migration for the patient index, and staff training on new billing workflows. Conducted 30-day parallel billing reconciliation at each facility. Achieved target claim rejection rate within 60 days of full deployment.
What we built
Master Patient Index
HL7 FHIR-based patient identity management across 6 hospitals. Probabilistic matching using demographics, phone, and ID number. Single patient timeline view for clinicians regardless of facility.
Integration Hub
OIC-based canonical integration connecting 6 HIS platforms from 4 different vendors. Standardised data exchange for patient, encounter, order, and billing data. Real-time and batch integration patterns.
ICD-10 Billing Validation
Automated ICD-10 code validation at the point of care. Completeness checks for insurance documentation. Coding suggestions based on clinical notes. Rejection prediction scoring before claim submission.
Revenue Cycle Dashboard
Real-time visibility into admissions, billing, collections, outstanding claims, and aging receivables across all 6 facilities. Drill-down by facility, department, payer, and claim status.
Insurance Claim Automation
Automated claim submission to 30+ insurance panels with payer-specific formatting. Real-time claim status tracking. Automated follow-up workflow for pending and rejected claims.
Unified Procurement
Centralised procurement across all 6 hospitals via Oracle ERP Cloud. Consolidated vendor management, group purchasing negotiations, and automated PO generation based on consumption patterns.
Measurable outcomes
- Insurance claim rejection rate reduced from 18% to 4%
- Unified patient record across 6 hospitals via master patient index
- Monthly billing reconciliation reduced from 5 days to same-day
- Revenue cycle visibility improved CFO decision-making speed by 60%
