Claims Processing

Claims processing is the full sequence a health plan follows once a claim arrives: intake and validation, benefit and eligibility verification, adjudication against plan rules and medical necessity criteria, and final payment or denial. The share of claims that pass through this process with no human intervention, straight-through processing, is one of the most closely watched efficiency metrics in the industry, since manual review is both slower and meaningfully more error-prone than automated adjudication.

It is the operational core of how a plan actually pays for care, and it touches almost every other function. Provider satisfaction depends on how quickly and accurately claims are paid. Member trust depends on whether denials are correct and clearly explained. Financial accuracy depends on whether the right amount was calculated against the right benefit. Because every claim runs through the same pipeline, small inefficiencies at any one step multiply across millions of claims, which is why plans invest heavily in making the process both faster and more consistent rather than treating it as routine back-office work.

Why It Matters

Manual claims handling carries a real accuracy cost that compounds at scale. Health insurers report an average claims-processing error rate of 19.3%, meaning close to one in five claims processed manually contains a mistake, and every one of those errors triggers rework that delays payment and consumes staff time that could otherwise go toward the exceptions that genuinely need human judgment.

Errors are also expensive in both directions. An overpayment has to be identified and recovered, which is slow and often incomplete, and an underpayment or wrongful denial generates appeals, provider abrasion, and potential regulatory exposure. The rework itself carries a cost of roughly $25 per claim, and that figure only captures the direct handling, not the downstream expense of appeals, provider calls, and lost trust. Reducing the number of claims that need a manual touch in the first place is therefore the most reliable lever a plan has for lowering both cost and error rate at the same time.

Health insurers report an average claims-processing error rate of 19.3%, nearly one in five claims, with manual rework costing roughly $25 per claim on average across the volume most plans process. (Industry benchmarking, 2025-2026)

How It Works

• Intake and validate. A claim is received electronically and checked for completeness and basic formatting errors before it enters the adjudication queue.
• Verify eligibility and benefits. Coverage, network status, and benefit limits are confirmed against the member's plan at the time of service.
• Adjudicate. The claim is evaluated against plan rules, medical necessity criteria, and pricing schedules to determine what is owed.
• Pay or deny. Approved amounts are paid to the provider or member, and denials are issued with a specific reason code that supports a potential appeal.

Key Metrics and Benchmarks

Straight-through processing rate (the share of claims adjudicated with no manual touch), financial accuracy, and average processing time are the three metrics that matter most in claims operations. Leading plans now push straight-through processing rates well above the historical 15-20% manual-review baseline, and automation applied to claims processing has been shown to cut cycle times by 30 to 75% depending on claim complexity, with the simplest, most standardized claim types seeing the largest gains.

Where Firstsource Fits

The practical challenge for most plans is not knowing that automation helps, but finding where accuracy and speed are actually leaking and fixing the root cause rather than the symptom.

Firstsource helps plans close these gaps in practice: one major national health plan rooted out claim leakage causes and costs with advanced claims management, reducing costs by identifying and fixing the root causes of leakage rather than simply reworking the claims after the fact. That distinction matters, because addressing the source of an error prevents the next batch of similar claims from failing, while reworking only clears the current backlog.

These gains sit within Firstsource's broader claims optimization capabilities for health plans, which combine automation for the high-volume, rules-driven claims with human review reserved for the genuinely complex exceptions.
