Design scalable insurance claims processing system
Design a Scalable Insurance Claims Processing System
Design an end-to-end insurance claims system for a health-focused insurance company, capable of handling claims from submission to payment. The system must be robust and support future growth.
High-Level Requirements
Actors
- Members / Policyholders: Submit claims, upload supporting documents (e.g., receipts, medical reports), and track the status of their claims.
- Providers (e.g., clinics, hospitals): May optionally submit claims on behalf of members.
- Claims Adjusters: Review claims, request additional information from members/providers, approve or deny claims, and trigger payments.
- Admins / Operations: Configure business rules, view operational dashboards, run reports, and audit historical data.
Core Functionality
- Claim Submission: Members or providers can submit a claim, which must include:
- Policy and member identifiers.
- One or more claim items (e.g., procedures, services, medications) with associated dates, codes, and amounts.
- Attachments (PDFs, images) as supporting documentation.
- Claim Validation: The system must validate submitted claims against defined policy coverage and business rules (e.g., coverage limits, pre-authorizations, exclusions).
- Claim Workflow: Claims must progress through a defined lifecycle: Submitted → Under review → Pending info → Approved → Denied → Paid.
- Status Tracking: Members can view the current status and historical details of their claims via web or mobile applications.
- Adjuster Processing: Claims adjusters need efficient tools to prioritize, search, and process claims.
- Payment Integration: Upon claim approval, the system must integrate with an external payment system to disburse funds to providers or members.
- Audit Trail: A comprehensive audit trail must be maintained for compliance purposes, recording who changed what and when.
Non-Functional Requirements (for a mid-sized insurer)
- Scalability: The system should handle tens of thousands of active users and millions of claims over time.
- Availability & Durability: High availability and durability of claim data are critical, ensuring no data loss.
- Latency: Common operations, such as viewing claim status, should have reasonable latency (e.g., < 200–500 ms).
- Security: Strong security and access control mechanisms are required, as claims contain sensitive health and financial data.
Design Deliverables
In your design, describe the following aspects:
- API and User Flows: Detail the APIs and user interaction flows for key operations (e.g., submitting a claim, viewing status, adjuster processing).
- High-Level Architecture: Outline the services/components, their interactions, and choices for data storage.
- Data Model: Propose a suitable data model for core entities such as Claim, ClaimItem, Policy, Member, Attachments, and ClaimEvents.
- Workflow/State Machine: Explain how you would implement the claim processing workflow and state machine.
- Scalability, Reliability, and Data Consistency: Address how these aspects would be handled across services.
- Security: Describe measures for authentication, authorization, data privacy, and audit logging.
- Integrations and Reporting: Explain integration strategies with external systems (e.g., payment processors, existing policy administration systems) and how reporting/analytics would be supported.
