Claims Processing

The end-to-end system by which payers receive, review, adjudicate, and pay healthcare claims submitted by providers.

Claims processing is the payer's internal system for handling every claim that comes in from every provider in their network. For large payers, this means processing millions of claims per month through automated systems with manual review queues for exceptions. The claims processing workflow starts when your claim arrives at the payer, either directly or through a clearinghouse. The system checks the claim format for compliance with HIPAA transaction standards. If the format is wrong, the claim is rejected back to you immediately, this is a rejection, not a denial, because the claim never entered the adjudication system. Claims that pass format validation enter the adjudication engine. The system runs the claim through a series of automated rules: member eligibility, provider enrollment, benefit coverage, coding edits, prior authorization requirements, duplicate claim detection, and fee schedule pricing. Claims that pass all automated rules are auto-adjudicated and queued for payment. Claims that fail one or more rules are routed to manual review. Manual review adds time. A claims examiner looks at the claim, determines why it failed automated processing, and either processes it, requests additional information, or denies it with a specific reason code. The time in manual review can range from a few days to several weeks depending on the payer's staffing and the complexity of the issue. State prompt payment laws and payer contracts specify how quickly claims must be processed. The standard is 30 days for electronic claims and 45 days for paper claims. If the payer misses these deadlines, you may be entitled to interest on the late payment. Understanding how claims processing works helps you optimize your billing practices. Submit electronic claims (faster processing), use correct payer IDs (avoid routing errors), verify eligibility before visits (prevent eligibility denials), include prior auth numbers (avoid authorization denials), and submit within days of service (avoid timely filing issues). The cleaner your claims are going in, the faster and more reliably they come out paid.
