The challenge
- A 6-week coding backlog driving delayed claim submission and cash flow disruption for provider clients
- Coding accuracy at 91%, below the industry-accepted 95% threshold for reimbursement optimisation
- Claim rejection rate at 12.4%, generating rework cycles and revenue leakage
- Difficulty recruiting AAPC-certified coders in the US onshore market at sustainable cost levels
- Increasing complexity of state-specific compliance and payer-specific coding rules
The Corpshore approach
- Recruited a dedicated cohort of AAPC-certified CPC and CCS coders from the Clark Freeport Zone workforce
- Established a HIPAA-compliant secure workstation environment with SOC 2 Type II certified operations
- Built a triple-layer QA process combining peer review, senior audit and randomized adversarial spot-check
- Deployed a proprietary coding workflow with an error catch-back mechanism to identify systemic coding issues
- Instituted a continuous education program with 40 hours per coder per year on updates and payer changes
