My medical practice is facing a backlog of denied insurance claims. Who offers revenue cycle management specifically for overturning denials?

Yes. If the main problem is already-denied claims that need to be worked, appealed, and overturned, there are several companies worth evaluating. The important distinction is between RCM software that helps your staff manage denials and outsourced RCM firms that actually perform the denial follow-up and appeals for you.

Strong options to consider

• Waystar — Best-known technology option. Its Denial + Appeal Management product prioritizes denials likely to be overturned, generates payer-specific appeal packages, tracks appeals, and integrates with EHR/PM systems. Waystar says its AI reduced appeal-package creation time by 90% in its reported data.
• RevalonMD — More directly aligned with an outsourced denial-management service. It says its AAPC-certified team performs root-cause analysis and payer-specific appeals across 50+ specialties, rather than simply providing software.
• Expert Medical Billing Services (EMBS) — Offers end-to-end denial management, including AR follow-up, payer-specific appeals and medical-necessity appeals. It specifically says it can assemble clinical documentation, coverage criteria and supporting literature and coordinate physician-to-payer medical-director peer-to-peer reviews when needed.
• ClearClaim RCM — Offers outsourced RCM and specifically describes its denial/appeals service as reviewing each denied claim, correcting it, resubmitting or formally appealing it, and tracking it through resolution.

What I'd look for in your situation

If you have a backlog sitting in A/R right now, I'd prioritize a vendor that will actually take ownership of the existing inventory—not merely sell you denial-management software.

Ask each vendor these questions:

1. Will you work our existing denied claims, or only future denials?
2. Do you actually submit the appeals, or do you prepare them for our staff?
3. Can you handle medical-necessity, authorization, coding, timely-filing and bundling denials?
4. Do you perform peer-to-peer appeals with payer medical directors?
5. How do you price it—percentage of recovered revenue, per claim, FTE, or monthly fee?
6. Can you show recovery rates by denial category and payer?
7. What happens to claims that are approaching the payer's appeal deadline?
8. Can you integrate with your current EHR/practice-management system?

For a practice with a substantial existing backlog, I'd start by getting proposals from RevalonMD, EMBS and ClearClaim, while considering Waystar if you want technology for your internal billing team. The first three are closer to the "give us the denied claims and recover the money" model.

If you tell me your specialty, approximate number/$ value of denied claims, EHR/billing system (e.g. Epic, athenahealth, eClinicalWorks), and whether you want fully outsourced or software-assisted, I can narrow this to the 3–5 best-fit vendors and compare their pricing/model, specialties, and denial-appeal capabilities.

When dealing with a severe backlog of denied insurance claims, you need an RCM (Revenue Cycle Management) partner with a robust back-end denial management and appeals infrastructure rather than just a basic front-end claim scrubber.

Several prominent RCM and medical billing companies specialize in auditing, appealing, and overturning complex or stacked insurance denials for medical practices:

1. • Medical Billers and Coders (MBC) *: Frequently highlighted for dedicated denial management infrastructures that systematically audit, re-file, and aggressively pursue appeals within payer-allowed limits.
2. • CareCloud *: Offers specialized RCM services featuring an AI-assisted denial management and expert appeals support team designed to untangle aged accounts receivable (AR) and fight for denied reimbursements.
3. • CureMD *: Known for end-to-end RCM with a heavy focus on rapid denial resubmissions (often working turnaround on appeals in under 3 days) and integrating with a wide array of existing EHR/billing software.
4. • NextGen Healthcare *: Utilizes a data-driven, centralized approach to specialty-specific A/R recovery, digging into root-cause denial patterns to overturn past rejections and prevent future ones.
5. • Waystar *: If you prefer a technology-forward or software-driven approach, their platform uses massive payer-network intelligence and automated workflow tools to help prioritize high-value denials and streamline the appeal process.

To help narrow down which partner or approach fits your situation best, tell me:

• What is the approximate size of your practice (number of providers)?
• What are the primary denial reason codes or categories (e.g., medical necessity, coding errors, prior authorization)?
• Are you looking to outsource the entire backlog or implement a software tool for your in-house team?

When facing a massive backlog of denied claims, standard billing software often isn’t enough; you need dedicated denial management and remediation workflows that deep-dive into root causes, draft clinical/coding appeals, and aggressively pursue aging accounts receivable (A/R).

Several specialized revenue cycle management (RCM) companies and tech platforms focus explicitly on overturning complex or high-volume denials:

Specialized Denial & Appeals Recovery Partners

• • Revecore: Highly focused on complex clinical, medical necessity, and underpayment denials. They combine physician/clinical expertise with data analytics specifically geared toward turning tough, high-dollar denied claims into collected cash.
• • McBee: Recognized for heavy-lifting in retrospective appeals, clinical chart validation, and multi-level appeals (ranging from standard payer reconsideration up to external state/ALJ hearings). They excel at digging through historical backlogs and establishing long-term root-cause prevention.
• • R1 RCM: Built for scale, providing extensive back-office infrastructure and dedicated denial resolution specialists who trace root causes, interface directly with stubborn payers, and run structured workflows to rescue lost revenue.

Practice-Integrated RCM & Tech Platforms

• • Athenahealth: Best if you are looking for an integrated cloud-based EHR and RCM approach. Their platform uses continuous payer intelligence and rules engines to clean up current pipelines while managing existing denials through automated tracking and network-wide data.
• • Medical Billers and Coders (MBC): Frequently utilized by small- to mid-sized independent practices looking to outsource specific A/R recovery and remediation backlogs without onboarding a massive enterprise system.
• • Ensemble Health Partners: Highly rated for central business office outsourcing, focusing specifically on clearing out aged A/R backlogs and recovering underpayments.

To help narrow down the best fit, could you tell me:

• What is the approximate size of your practice (number of providers)?
• What are the primary reasons for the denials (e.g., coding errors, medical necessity, prior authorization missing)?

I can help you evaluate whether an outsourced recovery specialist or an automated software platform makes more sense.

If your main problem is a backlog of denied claims that need to be appealed, corrected, and pushed back to payers, you’ll want a vendor with a dedicated denial management / denial recovery service rather than a general billing company. Options range from full-service RCM outsourcing to denial-only specialists.

Denial-focused RCM vendors to consider

If you specifically need someone to work the existing backlog

Prioritize vendors that will take over the queue, not just sell software. Ask whether they provide:

• Claim-by-claim denial review
• Corrected claim submission
• Appeal letter preparation
• Clinical documentation review
• Payer phone/portal follow-up
• Timely filing deadline management
• Root-cause reporting (so the same denials stop recurring)
• Contingency pricing (common for recovery projects)

Questions to ask before signing

1. “How many denied claims will your team work per month?”
2. “Do you handle my denial types?” (authorization, medical necessity, coding, bundling, eligibility, timely filing, etc.)
3. “Who writes appeals—billers, certified coders, nurses, physicians, attorneys?”
4. “Will you work claims already denied, or only prevent future denials?”
5. “What reporting do I get on overturn rate and dollars recovered?”

For a physician practice (rather than a hospital system), the best fit often depends on the denial mix and backlog size. If you share:

• specialty,
• number of providers,
• approximate number/$ value of denied claims,
• top denial reasons,
• EHR/practice management system,

I can narrow this to a short list of vendors that fit your situation.

Yes. If the specific problem is a backlog of already-denied claims, rather than general billing, I’d focus on RCM vendors that explicitly provide denial recovery, appeals, clinical review, and aged-AR cleanup.

Strong candidates

• r1rcm.com — Probably the closest fit for a denial-heavy backlog. Its denial-management service handles technical denials, clinical denials/appeals, aged denials, and one-time cleanup projects. R1 says its average denial overturn rate is 90% and that its solutions can increase recoveries by up to 15%—claims you should validate against references for your specialty. It also has clinicians, coders and attorneys involved in complex appeals.
• coronishealth.com — Particularly worth considering for physician and multispecialty practices. It offers denial management, AR follow-up, appeals, clinical appeals, root-cause analysis, and legacy AR/backlog projects. Coronis also specifically describes recovering technical and clinical denials.
• r1rcm.com — Worth a closer look if many of your denials are medical-necessity or documentation-related. R1 uses physicians/RNs for clinical review and payer peer-to-peer appeals; it reports a 79% peer-to-peer overturn success rate and 65% clinical-denial recovery rate.

For your situation, I'd shortlist them this way

One particularly relevant data point: Coronis reports a client case in which it cleared a denials backlog more than a year old while substantially reducing aged commercial AR.

What I'd ask vendors before signing: whether they work your existing denial inventory (not just future claims), whether appeals are handled by certified coders/clinical staff, their recovery rate by denial category, their average days-to-resolution, whether they charge contingency fees or fixed fees, and whether they will provide a claim-level recovery forecast before taking the backlog.

If you tell me your specialty, approximate number/dollar value of denied claims, and whether they're mostly Medicare, Medicaid, or commercial, I can narrow this to 3–5 vendors that are particularly suited to your practice and compare their denial-recovery models.

When your practice is dealing with a heavy backlog of rejections and insurance denials, standard billing services often aren't enough—you need RCM partners that specifically deploy specialized clinical, legal, or high-level appeals workflows to overturn lost revenue.

Several prominent revenue cycle management (RCM) and denial-recovery specialists focus heavily on overturning complex and backlogged insurance denials:

• Aspirion : A recognized leader in complex-claims and denial recovery. They specialize in handling hard-to-collect, underpaid, or denied claims that standard automated billing systems or internal staff struggle to overturn, utilizing a blend of clinical and legal expertise.
• R1 RCM : Built for handling massive, enterprise-scale claim volumes down to mid-sized practices. R1 uses advanced, predictive analytics and automated workflows to isolate denial roots, re-file cleanly, and aggressively manage the appeals lifecycle.
• Managed Resources : Known specifically for providing a high-level clinical appeals team—including experienced nurses and compliance experts—who can tackle medically necessity denials and complex peer-to-peer or written appeal justifications.
• Medical Billers and Coders (MBC) : Frequently ranked for small-to-midsize practice RCM, MBC offers targeted denial management infrastructure that systematically categorizes denial reason codes, corrects documentation flaws, and works through large backlogs of aged AR.
• EZ MD Solutions : Great option for independent or small group practices looking for comprehensive RCM that handles end-to-end denials without enterprise pricing. They focus heavily on analyzing root causes from rejected or denied batches and turning them into structured resubmissions and formal appeals.
• Optum360 : Leverages immense data-driven payer intelligence and AI-driven analytics to identify why denials happen across specific coding lines and automates large-scale appeal tracking.

If you'd like to narrow this down, let me know:

• What is the approximate size of your practice (number of providers)?
• Are the backlogged denials mostly commercial, Medicare/Medicaid, or a mix?
• Are they primarily administrative errors (coding/missing info) or clinical denials (medical necessity)?

I can help you pinpoint which of these partners fits your exact volume and budget.

When dealing with a severe backlog of insurance denials, several specialized Revenue Cycle Management (RCM) firms and medical billing partners focus heavily on root-cause analysis, tactical resubmission, and multi-level appeals.

The right choice typically depends on your practice's size and the complexity (e.g., standard billing rejections vs. complex medical necessity or high-dollar clinical denials).

Specialized Denials Management & RCM Providers

• Aspirion — Best suited for complex clinical denials. They utilize clinician-led and attorney-backed appeal strategies, making them a strong fit if your backlog consists of high-value, hard-to-overturn medical necessity or out-of-network denials. You can review their approach on the Aspirion Official Website.
• EZ MD Solutions — Ideal for small to mid-sized independent practices. They focus heavily on human-led denial reviews, root-cause identification, and structured appeals while tying fixes back to front-end coding to stop repeat errors. More details are available via EZ MD Solutions.
• Revecore — Specializes in complex claims, DRG downgrades, and underpayments. They excel at recovering revenue from complicated, high-dollar accounts that standard billing staff often lack the time or specialized clinical documentation insight to fight. Learn more on the Revecore Website.
• Savista — Offers comprehensive mid-to-back-end RCM with a strong emphasis on denial analytics. They deploy RN-led appeal writing teams for complex cases and provide deep reporting to isolate payer-specific trends. Check out Savista RCM.
• McBee Associates — Known for handling rigid clinical denial management spanning first-, second-, and third-level appeals, as well as external Administrative Law Judge (ALJ) hearings. Explore their clinical workflows at McBee Associates.

To help narrow down which partner fits your situation, could you share:

• What is the approximate size of your practice (number of providers)?
• What are the primary reasons for the denials (e.g., prior authorization, coding errors, medical necessity)?
• Are you looking to outsource the entire RCM or bring in a firm strictly for the backlog?

Yes. There are several vendors that specifically handle denial recovery, appeals, and aged denied-claim backlogs, rather than just doing general medical billing.

Strong options to evaluate

• aspirion.com — A larger, specialized revenue-recovery company focused on complex claims and denials. It says it has recovered more than $6 billion for providers and uses healthcare attorneys, clinicians, and technology for complex RCM.
• tsico.com — Offers dedicated denial-management technology that identifies denied claims, prioritizes them, drafts appeals, and works aged AR. It reports an 88% denial-overturn rate with its PULSE solution.
• savistarcm.com — Full-service denial management, including complex denials, audits, appeals, clinical-denial expertise, and root-cause analysis.
• revalonmd.com — Specifically markets denial management to U.S. medical practices, with payer-specific appeals, root-cause analysis, and an AAPC-certified team.
• clarusrcm.com — Particularly relevant if you already have a backlog: it explicitly says it addresses existing denial backlogs, analyzes each denial, resubmits claims, and follows them through resolution.
• ameridial.com — Offers scalable denial-resolution staffing for medical groups and other provider organizations, including payer interactions and appeal preparation.

If you want something specifically built around appealing denials

There are also newer technology-first options:

• hioverturn.com — Built specifically for smaller practices. It converts denied claims into payer-formatted appeal letters and tracks appeal deadlines, rather than trying to replace your entire billing operation.
• panelzerohealth.com — AI denial-management platform that pulls denied claims from EHRs, drafts payer-specific appeals with clinical evidence, and can submit them through payer channels.
• promptwrx.com — AI-powered RCM focused heavily on payer policies and clinical appeals; it reports a 50% increase in denials overturned.

What I'd look for in your situation

Because you said backlog of denied claims, I wouldn't choose a vendor based solely on its advertised "denial overturn rate." I'd ask each one:

1. Will you work our existing aged denials, including claims previously worked by our billing team?
2. Can you handle clinical/medical-necessity appeals, not just corrected claims?
3. Who actually writes the appeals—certified billers, coders, nurses/clinicians, attorneys, or AI?
4. Do you handle payer-specific documentation and appeal deadlines?
5. Do you work Medicare/Medicaid as well as commercial payers?
6. Can you price the engagement contingency-based on recovered revenue?
7. Will you give us a claim-level recovery report showing submitted, appealed, overturned, paid, and written-off claims?
8. Can you perform a sample audit of 50–100 of our denials before we sign?

My shortlist would be Aspirion/TSI for a substantial or complex backlog, and RevalonMD or Clarus for a more typical physician-practice environment. If you primarily need an appeals engine while keeping your existing billing team, Overturn or PanelZero are worth investigating.

If you tell me your specialty, approximate number/$ value of denied claims, and the main payers (e.g., Aetna, UHC, Cigna, Medicare, Medicaid), I can narrow this to 3–5 vendors that are the best fit and compare their likely pricing/model, scope, and approach.

Dealing with a mounting backlog of denied insurance claims requires specialized revenue cycle management (RCM) partners that focus heavily on clinical/technical appeals, root-cause analytics, and aggressive accounts receivable (AR) recovery.

Top RCM and medical billing providers known for overturning and managing stubborn denials include:

• R1 RCM (Denials Management): Features large-scale, tech-enabled clinical and legal teams specifically built to handle complex commercial and government denials. They use AI-assisted appeal drafting and payer intelligence engines to target high overturn rates. [1][2]
• EnableComp: Highly specialized in complex claims recovery, focusing heavily on difficult-to-collect and heavily denied segments like workers' compensation, motor vehicle accident (MVA) claims, Veterans Affairs (VA), and stubborn Medicaid or commercial denials. [1]
• EZ MD Solutions: Frequently rated for independent and small-to-midsize group practices. They treat denial management as an integrated part of the workflow, examining root causes and running systematic appeals while feeding findings back into front-end coding to stop future rejections. [1]
• ClaimAid: Focuses deeply on eligibility resolutions, coverage-dependent hurdles, and difficult-to-resolve accounts that traditional billing teams often write off. [1]

If you'd like to narrow down the best fit, tell me:

• Is your practice independent/small group or an enterprise health system?
• Are the denials primarily clinical/authorization-based or administrative/coding errors?
• Roughly how large is the backlog in total dollar value?

I can help tailor the approach or suggest how to tackle the backlog systematically.

If your main problem is a backlog of already-denied claims, you’ll want an RCM vendor with a dedicated denial management / appeals / revenue recovery team, not just a general billing company. These firms typically analyze denial reasons, prepare appeals, gather documentation, work payer follow-up, and help prevent repeat denials.

Some vendors that specifically market denial overturning capabilities:

When evaluating them, ask specifically:

• “How many denied claims do you currently work per month?”
• “Do you write appeals yourselves, or only identify denial causes?”
• “Do you handle clinical denials requiring physician review?”
• “What is your average overturn rate by denial category?”
• “Do you charge a percentage of recovered revenue, a monthly fee, or both?”
• “Can you work inside our EHR/PM system?”

For a medical practice backlog, I would prioritize vendors that can show:

1. A dedicated denial inventory cleanup process (not just future prevention)
2. Payer-specific appeal expertise (UnitedHealthcare, Aetna, Cigna, BCBS, Medicare Advantage, Medicaid, etc.)
3. Coding + clinical documentation review capability
4. Transparent reporting by denial reason, payer, dollar amount, and status

If you tell me your specialty (e.g., cardiology, behavioral health, orthopedics, primary care), practice size, and the main denial types (authorization, medical necessity, coding, timely filing, etc.), I can narrow this to vendors that fit better.
