What is payment integrity in healthcare?

Payment integrity in healthcare is the discipline of ensuring that claims submitted to a health plan are paid correctly, in the right amount, to the right provider, for services that were actually delivered and appropriately authorized, in accordance with the plan’s contract terms and benefit design. It applies across both medical and pharmacy benefits, though the administrative structures, error profiles, and oversight models differ significantly between the two. Where payment integrity programs exist, they serve as an independent check on whether the systems processing claims are executing as intended.

The concept is straightforward, but the execution is not. Health plans contract with vendors and service providers to administer benefits on their behalf. Each of those relationships involves negotiated terms, pricing schedules, clinical rules, and regulatory requirements that must be translated into adjudication logic and applied to every claim. Payment integrity is the mechanism that detects when the translation breaks down.

Why payment integrity exists

Health plans invest significant resources in designing benefits and negotiating the contract terms that govern how those benefits are administered. Payment integrity exists to verify that this work is reflected accurately at the claim level.

The challenge is structural, not adversarial. Claim adjudication is handled by systems and vendors that operate at enormous scale: millions of transactions per year across thousands of pricing rules, eligibility conditions, and clinical protocols. Even small configuration errors, when applied systematically to a class of claims, produce meaningful financial impact. A dispensing fee that deviates from the contracted rate by a few cents per claim generates thousands of dollars in overpayments across a full book of business. A coordination of benefits rule that is miscoded for a subset of members affects every claim for every affected individual.

Without independent oversight, these errors persist because the entity processing the claims is also the entity reporting on their accuracy. Payment integrity introduces a third-party perspective that can verify execution against the plan’s actual terms.

Payment integrity on the medical side

Most health plans are already familiar with payment integrity through their medical benefits. Medical payment integrity focuses on claims for physician services, hospital stays, outpatient procedures, and ancillary care. Common areas of review include coding accuracy, billing compliance, duplicate claims, unbundling of services that should be billed together, and provider credentialing. Medical payment integrity programs typically involve a mix of pre-payment editing and post-payment audit, and many plans have had these programs in place for years.

What makes medical payment integrity relatively straightforward, in structural terms, is that health plans often adjudicate medical claims through their own systems or maintain direct visibility into the adjudication logic. The plan and the claims processor are often the same entity, or at least operate on shared infrastructure. That visibility makes oversight more accessible, even if the clinical and coding complexity is high.

Why pharmacy payment integrity is different

Pharmacy payment integrity operates in a fundamentally different administrative environment because of the pharmacy benefit manager (PBM). The PBM controls claim adjudication, formulary management, pharmacy network contracting, and rebate negotiation. The health plan retains the financial and regulatory risk but delegates the operational execution to an entity running its own technology stack and applying its own configuration of the plan’s terms.

This separation creates a verification gap that does not exist in the same way on the medical side. The plan cannot see inside the PBM’s adjudication engine. It cannot confirm, transaction by transaction, that its benefit design is being implemented as written. It relies on the PBM to both process claims and report on the accuracy of that processing. Independent pharmacy payment integrity exists to close that gap.

Common findings include pricing misapplications, coordination of benefits errors, member cost-share miscalculations, incorrect generic or brand adjudication, rebate shortfalls, and configuration drift after mid-year formulary or benefit changes. Because pharmacy benefits involve hundreds of distinct rules governing copay tiers, substitution logic, accumulator programs, specialty drug handling, and pricing methodologies, the surface area for implementation error is substantial. And because the PBM processes claims at volume, systemic errors compound quickly.

At Rivera, pharmacy payment integrity is delivered through a library of 750+ proprietary algorithms, each tied to a specific question about how the benefit should be adjudicated. These algorithms are configured from the plan’s actual contract and benefit design, not from generic compliance rules. The library compounds: findings from one client inform the algorithms applied across all clients, which means the system becomes more precise as it scales. Rivera works directly with health plans and self-funded employers, and through channel partners who bring independent pharmacy oversight as a differentiated service to their own clients.

The three dimensions of payment integrity value

Effective payment integrity programs produce value in three ways, regardless of the benefit type.

Recovery is the most visible output. Claims that were paid incorrectly are identified, documented, and recovered. This is the number that shows up on a board report and justifies the investment. For most health plans, first-year recoveries exceed the cost of the program.

Recurrence prevention is where the compounding value begins. When an error is identified, the root cause is diagnosed and the underlying configuration, pricing logic, or contract interpretation is corrected so the same error stops appearing on future claims. Recovery addresses what already went wrong. Recurrence prevention ensures it does not happen again. For a deeper look at how these mechanisms produce measurable ROI, see our analysis of pharmacy payment integrity returns.

Contract leverage is the strategic dimension. A health plan entering a vendor contract renewal with twelve months of independently validated, claim-level performance data is in a fundamentally different negotiating position than one relying on vendor-supplied reports. This is particularly consequential in pharmacy, where PBM contract negotiations determine billions of dollars in annual spend.

The regulatory environment is raising the bar

Payment integrity has historically been a voluntary best practice. That is changing. The Consolidated Appropriations Act of 2026 introduced new transparency, rebate pass-through, and reporting requirements for PBMs servicing health plans. The DOL has proposed sweeping fee disclosure rules under ERISA Section 408(b)(2). State-level spread pricing bans and managed care oversight requirements continue to expand.

These developments raise the floor for what health plans are expected to know about how their benefits are being administered. But disclosure is not verification. A PBM can comply fully with statutory reporting requirements while the plan still absorbs claim-level execution errors that no disclosure regime is designed to catch. Payment integrity fills the gap between what regulations require vendors to disclose and what plans need to independently confirm.

Frequently asked questions about payment integrity in healthcare

What is the difference between payment integrity and fraud, waste, and abuse (FWA)?

FWA programs focus on detecting intentional fraud, inappropriate billing, and wasteful utilization. Payment integrity is broader. It encompasses FWA but also covers unintentional errors: pricing misapplications, configuration mistakes, contract interpretation discrepancies, and adjudication logic that diverges from the plan’s design. Most payment integrity findings involve systemic errors, not bad actors. The financial impact of those systemic errors often exceeds what FWA programs surface.

Is payment integrity the same as claims auditing?

Claims auditing is one method within payment integrity, but it is not the only one. Traditional audits are periodic, sample-based, and retrospective. Continuous payment integrity programs review 100% of claims on an ongoing basis, surface findings earlier, and address root causes to prevent recurrence. An audit tells you what went wrong. A continuous program tells you what went wrong, fixes it, and confirms it stays fixed.

Why is pharmacy payment integrity more complex than medical payment integrity?

The PBM intermediary structure creates a verification gap that does not exist in the same way on the medical side. In medical claims, the health plan often adjudicates through its own systems or has direct visibility into the adjudication logic. In pharmacy, the PBM operates as a separate entity with its own technology stack, applying its own configuration of the plan’s terms. The plan bears the financial risk but cannot independently see whether each claim is being processed correctly without a third-party oversight program.

How does payment integrity differ between pharmacy and medical benefits?

Medical payment integrity often focuses on coding accuracy, billing compliance, and utilization review. Pharmacy payment integrity focuses on contract execution: whether the PBM is applying the plan’s pricing terms, formulary rules, copay structures, and coordination of benefits logic correctly at the claim level. The error profiles, data structures, and vendor relationships are different, which is why pharmacy payment integrity has become a specialized discipline.

Do health plans need a separate payment integrity program for pharmacy?

In most cases, yes. The administrative systems, contract structures, and error patterns in pharmacy are distinct from medical. A medical payment integrity program will not catch pharmacy-specific issues like PBM pricing misapplications or formulary configuration drift. Pharmacy payment integrity requires specialized expertise because of the PBM relationship, the volume of distinct adjudication rules, and the compounding nature of systemic errors in high-volume claim categories.
