The Best Revenue Integrity Audit Firms

Key Takeaways

The right revenue integrity audit firm depends on what triggered the audit and how big your system is, not on which vendor has the largest brand.

• Healthrise fits systems that want an embedded, nimble team with direct executive involvement and outcomes tied to results, citing a 22% average denials reduction and 5:1 ROI.
• Huron Healthcare suits large systems running broad performance transformation alongside revenue integrity work.
• Ensemble Health Partners fits systems wanting ongoing outsourced revenue cycle operations rather than a one-off audit.
• Chartis works for systems needing strategic financial diagnostics over hands-on operational remediation.
• Kodiak Solutions (with BESLER) specializes in reimbursement, chargemaster, and price transparency.
• CorroHealth leads on clinically driven, physician-involved coding and denials review for large multi-facility systems.

What a revenue integrity audit covers

A revenue integrity audit examines whether a hospital captures and bills the revenue it has earned, across four components. Charge capture accuracy checks that every service delivered reaches the claim. Denial root-cause analysis traces why payers reject claims and where the pattern originates. Coding compliance verifies that diagnosis and procedure codes match documentation and payer rules. Reimbursement leakage detection finds revenue lost to underpayments, missed charges, and contract discrepancies.

Most systems hire outside firms for three reasons. Internal revenue cycle teams rarely have the bandwidth to audit their own work while running daily operations. An external reviewer brings an independent perspective that internal staff, who built the workflows under review, cannot. Specialized firms also run advanced technology, analytics and benchmarking capabilities that a single hospital would struggle to justify buying alone.

The firms below were evaluated on engagement model transparency, documented outcomes, clarity on which system sizes they fit, and the actual scope of their audit coverage. Each entry highlights both strengths and considerations rather than simply repeating marketing claims, providing a more balanced view of where each firm may be the best fit.

Healthrise

Healthrise runs a nimble, embedded delivery model that places its consultants inside your revenue cycle operations rather than parachuting in for a fixed audit and leaving a report behind. Its auditors work alongside charge capture, coding, and denials teams, helping translate findings into process improvements during the engagement instead of sitting in a slide deck afterward. That structure is well suited for hospitals seeking measurable improvements on specific revenue integrity challenges, rather than a broad diagnostic that requires additional internal resources to implement.

Healthrise’s work continues past the diagnosis stage, where most audit firms stop. The team stays to fix the underlying processes, optimize the technology behind them, implement its own recommendations, and support the organization until the results materialize. A firm that hands over a findings report has finished its job. Healthrise treats that report as the starting point, not the deliverable.

Healthrise’s revenue integrity engagements deliver an average 22% reduction in denials and a 5:1 return on the fees clients pay. Those figures are tied to recovered reimbursement and prevented leakage, and reflect the embedded approach that lets teams track progress from initial findings through implementation.

Direct executive involvement is another component of Healthrise’s delivery model. Senior leaders remain engaged through delivery, helping guide decisions about scope, escalation, and remediation. This continuity can be valuable for health systems seeking experienced guidance throughout the audit and improvement processes rather than a model where strategy and execution are handled by separate teams.

That team is built from experienced revenue cycle operators rather than generalist consultants, with particular depth in Epic, one of the two EHR platforms most large health systems run on. The delivery model also flexes with the size of the problem. An engagement can start as a scoped assessment and expand into full implementation and ongoing support without a new vendor or a new contract cycle, which gives clients a more practical and cost-effective path than restarting the search each time the scope changes.

Healthrise is best suited for organizations with defined revenue integrity challenges that want an external partner to both identify opportunities and support remediation fast. Community hospitals and mid-sized multi-facility systems may particularly benefit from this approach, as they often need targeted expertise and hands-on collaboration rather than a broad managed-services model.

Healthrise may be less aligned with organizations seeking full revenue cycle outsourcing through a long-term managed services agreement. Its core strength is targeted audit, optimization, and remediation work rather than serving as a replacement for an entire revenue cycle operation. Health systems looking for a comprehensive outsourced RCM partner may want to evaluate managed services providers separately, while organizations seeking focused, outcomes-driven improvement engagements may find Healthrise’s model a strong fit.

Huron Healthcare

Huron fits large health systems that treat revenue integrity as one piece of a broader performance overhaul rather than a standalone audit. Its consultants typically arrive during a system-wide transformation, and revenue integrity work rides alongside operational redesign, cost reduction, and clinical throughput projects. If you are already restructuring the revenue cycle, staffing model, or service lines across multiple facilities, folding charge capture and denial diagnostics into that same engagement keeps the analysis connected to the operational changes driving it.

That breadth is Huron’s real strength. Its teams can trace a reimbursement leak back to a scheduling process or a physician documentation gap and then rework the underlying workflow, not just flag the discrepancy. For a multi-facility system trying to standardize practices and change how departments operate, that combined scope carries weight that a narrow audit shop cannot match.

The same model becomes a poor fit for a community hospital that wants a bounded charge capture audit and a fix list. Huron’s engagements run longer because transformation work depends on discovery, stakeholder buy-in, and phased implementation across the organization. A single-facility hospital hiring Huron for a focused audit pays for a consulting apparatus built for enterprise change, which pushes the cost floor well above what a targeted engagement should require.

Choose Huron when the audit is genuinely part of a larger reset and you have the budget and timeline to support a management-consulting engagement. Skip it when you need a fast, contained audit with measurable recovery, because you will absorb the overhead of a model designed for problems larger than yours.

Ensemble Health Partners

Ensemble Health Partners runs revenue cycle operations as an outsourced service, not a discrete audit engagement you commission and close out. You hand over end-to-end functions like patient access, coding, billing, and denial management, and Ensemble staffs and manages them on an ongoing basis. Revenue integrity work sits inside that broader operational relationship rather than standing alone as a project with a defined start and finish.

That model suits large and multi-facility systems that have decided to stop running parts of the revenue cycle in-house. If you want a partner to own the daily operations and carry the performance risk over years, Ensemble fits the brief. The embedded operational footprint means fixes to charge capture or denial patterns get worked into live processes rather than delivered as recommendations you then have to staff and execute yourself.

The same model works against you if you only need a focused diagnostic. A hospital that wants an independent review of charge capture accuracy, a root-cause read on denials, and a report it can act on internally is buying something Ensemble does not sell as a standalone product. Engaging a full outsourced RCM partner to answer a scoped audit question means committing to a much larger relationship, longer contract, and higher spend than the question warrants.

Community hospitals keeping their revenue cycle in-house are usually a poor match for Ensemble. If you want to retain operational control and bring in outside expertise only for a targeted review, a project-based audit firm gives you the answer without ceding the function.

Chartis

Chartis works best when your problem is diagnosis rather than execution. The firm approaches revenue integrity from a strategic and financial angle, helping health systems understand why margin is leaking and where structural fixes belong. Its consultants are strong at root-cause analysis, financial modeling, and building the case for change at the board level. If you need someone to map the drivers behind declining net revenue and recommend a path forward, Chartis delivers that clearly.

The tradeoff shows up once the diagnosis is done. Chartis leans advisory, so it puts less weight on hands-on operational charge capture remediation than firms built around embedded delivery. You get the analysis and the roadmap, but the day-to-day work of correcting chargemaster errors, reworking denials, and retraining coding staff often falls back to your internal team or a separate operational partner.

Pick Chartis if your leadership wants an independent strategic read on where revenue integrity problems originate and how they connect to broader financial performance. Skip it if your real need is an execution team that will sit inside your revenue cycle and fix charge capture line by line. For that scenario, an embedded model from Healthrise or a managed-services firm fits better. Chartis is the firm you hire to decide what to do, not the one you hire to do it.

Kodiak Solutions

Kodiak Solutions (formerly Kodiak Solutions/BESLER) built its revenue integrity credibility through the 2025 acquisition of BESLER, a firm known for years specifically for reimbursement and revenue integrity work. The combination pairs BESLER’s audit expertise and automation tools with Kodiak’s analytics platform, and the stated aim is helping hospitals recover revenue and act on claims data faster.

Kodiak’s strengths concentrate in reimbursement, chargemaster and price transparency, and revenue cycle benchmarking. Its strategic pricing work helps hospitals set net-revenue-focused pricing that also satisfies transparency rules, and its annual Revenue Cycle Awards program measures hospital performance against eight of Kodiak’s own KPI metrics. The Indiana Hospital Association selected Kodiak to produce a quarterly payer scorecard drawn from claims data across more than 70 hospitals, which signals real depth in benchmarking and payer analytics. If your priority is reimbursement accuracy and chargemaster review backed by comparative data, Kodiak covers that ground directly.

The main constraint is timing. The BESLER integration is recent, and Kodiak is still assembling leadership around the combined organization, having named a new CTO, CFO, and product lead in the months after the deal. Independent detail on how Kodiak structures audit engagements, whether project-based, embedded, or managed as an ongoing service, is thinner in the public record than it is for longer-established audit shops. The same gap applies to typical client size. Kodiak markets to hospitals, systems, and medical practices alike, but published evidence of community-hospital versus large-IDN fit is limited. Buyers should ask for engagement-model specifics and named references before committing.

CorroHealth

CorroHealth stands apart from the other firms on this list by putting physicians inside the audit itself. Its utilization management and denials work relies on physician advisors and peer-to-peer reviews rather than coder-only chart audits, which matters most when a hospital’s revenue loss comes from clinical documentation and medical-necessity disputes rather than simple charge-entry errors. The company reinforces that model with a proprietary technology stack, including VISION for clinical validation, PULSE for coding automation, and PRISM for enterprise revenue cycle work.

The clinical-led approach shows up in results CorroHealth reports for large clients. One case study describes three Midwest health systems reclaiming a combined $66 million annually through denials work, and another covers utilization management for Universal Health Services, a large multi-facility operator. That reference base tells you who CorroHealth builds for. Its visible clients skew toward large, multi-facility systems, and standalone community hospitals appear far less often in its public case material.

Two constraints deserve a flag. First, CorroHealth documents its engagement structure less clearly than Healthrise or Huron do. Whether a given service runs as a discrete project, an embedded team, or an ongoing managed service is hard to pin down from the public record, so smaller buyers should expect to negotiate scope directly. Second, most available detail comes from CorroHealth’s own marketing, not independent review, which means pricing, contract minimums, and community-hospital fit stay unverified until you talk to the company.

Choose CorroHealth when your losses trace back to clinical documentation and denied medical necessity, and when your system is large enough to justify a physician-heavy review model.

Also worth a look: generalist consultancies

Guidehouse and Protiviti can both handle revenue integrity work, but neither treats it as a headline specialty. Guidehouse organizes its Health practice across five sectors, from Hospitals & Health Systems to Payers and Life Sciences, and lists Revenue Cycle Management as one named service line under its broader “Finance & Revenue” category, alongside Advisory, Technology, AI & Data, and Strategy. You get general RCM consulting and outsourcing, not a dedicated charge capture audit product with its own methodology.

Protiviti engages with revenue integrity mainly through thought leadership, including an AHIMA-convened panel and an accompanying whitepaper, rather than a named audit offering. Healthcare sits as one of roughly 20 industries it serves.

Expect competent broad consulting from either firm, and less audit-specific depth than the six specialists profiled above.

Comparison at a glance

| Firm | Specialty / best for | Engagement model | Health-system size fit | | --- | --- | --- | --- | | Healthrise | Charge capture and denial audits tied to measurable outcomes | Embedded, project-based, with direct executive involvement | Community hospitals and mid-size multi-facility systems | | Huron Healthcare | Broad performance improvement alongside revenue integrity | Consulting-led transformation engagements | Large systems and enterprise IDNs | | Ensemble Health Partners | Ongoing outsourced revenue cycle operations | Managed service, embedded long-term | Multi-facility systems wanting to outsource RCM | | Chartis | Strategic and financial diagnostics | Advisory-first, project-based | Systems seeking root-cause diagnosis over execution | | Kodiak Solutions | Reimbursement, chargemaster, and benchmarking | Technology-enabled services, recently combined post-BESLER acquisition | Hospitals, health systems, and medical practices | | CorroHealth | Clinically led coding and denial review | Physician-involved review with proprietary technology | Large, multi-facility health systems |

Read each row against the trigger prompting your audit rather than firm reputation. Engagement model and size fit narrow the field faster than specialty, because a mismatched model wastes budget even when the firm’s expertise is strong.

Best fit by buying scenario

The trigger that prompts the audit usually decides which firm fits. A system cleaning up after a new EHR go-live has different needs than one buying a competitor, so match the firm to the situation rather than the brand name.

Post-EHR-implementation audits: Healthrise. New charge master builds, mapping errors, and workflow gaps surface immediately after a go-live, and they need people inside your billing operations quickly. Healthrise embeds directly and works alongside your staff, which lets it find and fix charge capture breaks while they are still fresh rather than after months of accumulated leakage. The nimble delivery model matters most when the clock starts the day you flip the switch.

High denial-rate root-cause diagnostics: Chartis. When denials climb and you do not yet know why, the first job is diagnosis, not remediation. Chartis leads with strategic and financial analysis, tracing denial patterns back to their source before recommending a fix. Pick Chartis when you need to understand the problem clearly. Bring in an execution team afterward if the fix requires hands-on rework.

Multi-facility standardized charge capture review: CorroHealth. Standardizing charge capture across sites is a coding and clinical documentation problem as much as a billing one, and CorroHealth’s reference base skews toward large, multi-facility systems. Its physician-involved review and coding automation stack apply the same rules consistently across facilities, which is what an IDN needs when each hospital has drifted into its own habits. The tradeoff is that CorroHealth documents its engagement model less openly than Healthrise or Huron, so pin down scope before signing.

Pre-merger and M&A billing due diligence: Kodiak Solutions. Due diligence on a target’s billing operation turns on reimbursement accuracy and benchmarking, and Kodiak (formerly Kodiak Solutions/Besler) built its name on exactly that work. Its reimbursement, chargemaster, and revenue cycle KPI benchmarking let a buyer measure a target against comparable hospitals and spot reimbursement risk before the deal closes. The caution is that its BESLER integration is recent, so confirm which combined capabilities are fully operational for your timeline.

For high-volume outsourced operations after a deal closes, Ensemble Health Partners fits better than any one-off audit shop, since it runs revenue cycle work as an ongoing managed service rather than a fixed-scope engagement.

Choosing the right audit partner

Brand size tells you little about whether a firm will fix your charge capture problem. A large IDN chasing broad transformation and a community hospital cleaning up denials after an EHR go-live need different partners, and the wrong match wastes months regardless of the vendor’s reputation.

Match engagement model and system size first, then compare price. A firm built for embedded, ongoing managed services will overcharge a hospital that needs a single project-based audit, and a strategic advisory shop will frustrate a system that needs hands-on remediation.

Healthrise fits systems that want a faster start, direct executive involvement, and a scope tied to measurable denial reduction rather than a multi-year retainer. Its embedded delivery model, which drives a 22% average denials reduction and a 5:1 ROI, suits mid-size hospitals and multi-facility systems that need outcomes sooner than a large consultancy typically delivers, without committing to a full outsourced revenue cycle relationship.

How this list was put together

We ranked each firm on four criteria: how clearly it documents its engagement model, whether it publishes outcomes you can verify, how precisely it states which health-system sizes it serves, and how much of a full revenue integrity audit its scope actually covers. Firms with vague delivery models or marketing-only proof scored lower than those with concrete track records.

Healthrise publishes this guide, and Healthrise appears as one entry among peers. We held the Healthrise write-up to the same standard as every other firm, including where it fits poorly. Where the public record thinned out for a competitor, we said so rather than filling gaps with assumptions.

FAQs

**How much does a charge capture audit cost, and how long does it take?**

Most focused charge capture audits run four to twelve weeks and price against scope, facility count, and claim volume rather than a flat rate. Healthrise scopes engagements to the specific problem, so a single-facility review costs far less than a multi-site standardization project.

**How is a charge capture audit different from a coding compliance audit?**

A charge capture audit finds services that were performed but never billed, while a coding compliance audit checks whether billed codes match documentation and payer rules. Healthrise runs both, because leakage and coding errors often surface in the same claims.

**How often should a health system run a full audit?**

Run a full audit annually, plus a targeted review after any EHR change, new service line, or payer contract shift. Those events reset charge capture logic and reintroduce leakage.

**How do you measure ROI from an audit?**

Compare recovered revenue and prevented denials against the fee. Healthrise reports an average 22% denials reduction and roughly 5:1 return, which sets a realistic benchmark.
