Medical Claims Clearinghouse Architecture Diagram

Modernizing Legacy Claims Clearinghouse with Real-Time Adjudication Rails

A healthcare revenue cycle enterprise faced 72-hour batch EDI processing cycles, an 18% first-pass claim rejection rate, and costly manual re-submission workflows.
Codixon engineered an event-driven claims orchestration engine replacing legacy batch EDI 837/835 processing with real-time FHIR transformation and automated pre-submission scrubbing, cutting first-pass rejection rates by 68%.

Technical Constraints

Legacy Clearinghouse Inefficiencies

Decades-old batch mainframes, opaque payer error logs, and brittle flat-file schemas choked revenue flow across provider networks.

Brittle EDI 837/835 Batch Processing

Batch Dependency

Claims were pooled into nightly flat-file batch drops; syntax errors or missing NPI numbers aborted entire batch files without early notification.

Opaque Payer Rejection Feedback

Denial Visibility

Payer remittance advice (835) arrived days later with cryptic denial codes, forcing billing teams into manual phone and portal audits.

Disconnected Eligibility Verification

Eligibility Gaps

Lack of real-time 270/271 eligibility checks at the point of care generated downstream denials for expired coverage and unverified co-pays.

High A/R Days & Working Capital Drag

Working Capital

Multi-day parsing windows delayed provider reimbursements, ballooning Days Sales Outstanding (DSO) and complicating cash forecasting.

Engineering Blueprint

Streaming Claims Pipeline & Intelligent Scrubbing

A modern event-driven clearinghouse engine bridging legacy X12 standards with real-time RESTful FHIR APIs.

01
TRANSFORMATION

Streaming X12 EDI to FHIR Translation

Constructed high-throughput Rust and Go microservices that convert EDI 837 claim files into structured FHIR Claim and Coverage resources in milliseconds.

02
SCRUBBING

Pre-Submission Algorithmic Scrubbing

Engineered dynamic rule engines validating ICD-10, CPT, and NPI identifiers against current CMS guidelines to trap syntax and billing errors before submission.

03
CLEARING

Multi-Payer Direct API Routing

Deployed smart routing adapters connecting directly to major commercial and government payer gateways, replacing intermediary toll clearinghouses.

04
RECONCILIATION

Automated Remittance & Denial Matching

Built real-time 835 payment posting pipelines automatically reconciling Electronic Remittance Advice (ERA) entries against original clinical claims.
