Denial Management - Get Paid for the Claims Others Give Up On

Us vs. Typical Billing Company: Denial Management

Common Problems in Denial Management

Denials Are Coming In Faster Than You Can Fight Them

When a big share of your claims bounce on the first try, the pile of rework grows faster than your team can clear it. Denials aren't patient: every payer sets a window for appeals, and a denial that sits in the queue too long ages past the point where anyone can fight it. Past that line, being right no longer matters - the money is gone on a technicality.

Denied Claims Are Quietly Falling Through the Cracks

Denials arrive scattered across payer portals, remittance files, and mailed letters, and without one system that captures every single one, some simply never get logged. A denial nobody logged is a denial nobody works. Practices routinely discover, when someone finally reconciles billed against paid, that a meaningful slice of their revenue vanished this way - not disputed, not appealed, just forgotten.

Weak Appeals Get Rejected and Waste the Effort

An appeal is an argument, and payers reject weak ones. A generic letter that restates the claim without addressing the specific denial reason, in the format that specific payer requires, with the documentation that payer wants attached, usually loses - which means your team burned an hour of work and still didn't recover the money. Losing appeals also teaches staff that appealing is pointless, so fewer denials get fought at all.

The Same Denials Keep Happening Over and Over

Most denial volume isn't random - it's a handful of recurring causes generating the same denial month after month: a registration field entered wrong, a service billed before verification, a payer rule nobody flagged. If all your team ever does is fix individual denials, the leak refills as fast as you bail. The pattern only stops when someone traces denials back to their cause and fixes the process.

Fighting Denials Is Burning Out Your Staff

Denial rework is grinding, thankless work: hold queues, resubmissions, letters that get rejected on formatting. Staff stuck in that loop full-time make more errors, resent the work, and eventually leave - taking their hard-won payer knowledge with them. And because they're always reacting, nobody ever has time for the prevention work that would shrink the pile.

Money You Earned Is Being Written Off

Industry research has consistently found that a large share of denied claims are never resubmitted or appealed at all - even though many denials are overturnable when actually worked. Every unworked denial becomes a write-off, and a write-off is care your physicians delivered, documented, and billed, converted to zero. It's usually the largest recoverable pool of money in a struggling revenue cycle.

How We Approach Denial Management End to End

We See Every Denial and Why It Happened

Step one is simply seeing everything. Every denial from every payer gets pulled into one tracked worklist the day it arrives - no portal left unchecked, no paper letter lost in a stack. Each one is categorized by what actually caused it, so instead of a chaotic pile you get a clear picture: these five causes are producing most of your denials, and here's what each is costing you.

• Every denial tracked across all payers
• Grouped by reason so patterns stand out
• Root causes identified, not just symptoms
• Trends flagged before they cost you more

Appeals Built to Actually Win

An appeal that wins answers the denial's actual reason, in the payer's required format, with the exact supporting records attached. Our appeal writers know what each of your payers responds to - which arguments work, which clinical documentation to pull, when to cite the payer's own published policy back at them - and when a first-level appeal is wrongly denied, we escalate to the next review level instead of accepting the loss.

• Professionally written appeals
• Tailored to each payer's requirements
• Backed by the right supporting records
• Escalated further when a first appeal fails

Stopping Denials Before They Happen

Winning appeals recovers money once; fixing causes recovers it every month afterward. When the tracking data shows a recurring cause - coverage not verified before visits, authorizations missed for certain procedures, a claim error repeating from one workflow - we fix that upstream process, not just the individual claims. Over time this is what actually shrinks your denial volume rather than just managing it.

• Claims checked for errors before they go out
• Coverage verified before the visit
• Accuracy reviewed upfront
• Authorizations tracked and managed

Nothing Slips Past a Deadline

Every denial carries a countdown - the payer's appeal deadline - and our worklists are built around it. Denials are worked in priority order by deadline and dollar value, so the claim expiring soonest and worth the most gets attention first, and no recoverable dollar is lost because a deadline passed while the claim sat in someone's inbox. Every action taken is logged, so you can see exactly what happened on any claim.

• Denials worked in priority order
• Deadlines tracked so claims don't expire
• Less manual chasing for your team
• A full record of every action taken

What's Included in Denial Management, in Detail

Denial Analysis & Reporting

Every denial tracked, categorized by cause and payer, and reported back to you in plain terms - which payers deny you most, for what reasons, at what cost - so decisions about your revenue cycle rest on data instead of anecdotes.

• Denial reason categorization
• Payer-specific analysis
• Trend identification
• Custom reporting dashboards

Appeals & Reconsiderations

Professionally written appeals tailored to each payer's process and backed with complete supporting documentation, filed within the deadline and escalated through additional review levels when a valid claim is wrongly denied again.

• Expert appeal writing
• Documentation gathering
• Payer-specific strategies
• Multi-level appeals

Root Cause Resolution

The denial data gets traced back to whatever is producing it - a front-desk step, a documentation gap, a payer policy change nobody caught - and that process gets fixed, with your staff trained on the change so it sticks.

• Pattern recognition
• Process improvement
• Staff training
• Workflow optimization

Denial Prevention

Claims get checked before submission against the same rules payers will apply after - coverage active, authorization on file, information complete - so the errors that would have become next month's denials get caught while they're still cheap to fix.

• Pre-submission validation
• Coding review
• Eligibility verification
• Authorization tracking

How Denial Management Delivers Results

Denial Audit & Categorization

We start with your existing backlog: every denied claim gets reviewed, sorted by cause - clinical, administrative, or technical - and triaged by how much it's worth and how much appeal time remains. This first pass tells you three things most practices can't answer: how much denied money is still recoverable, which of it is most urgent, and which handful of causes are generating most of the volume.

Appeal Strategy Development

For your most frequent denial types, we build the winning argument once: the right letter structure for that payer, the clinical documentation that supports it, the payer policy language to cite. That preparation means each subsequent denial of the same type gets a strong, fast, consistent appeal instead of a from-scratch effort that varies with whoever writes it.

Systematic Appeal Submission

Appeals go out in deadline order with complete documentation attached, and each one is tracked until the payer responds. When a first-level appeal is denied on a claim that deserves to be paid, we escalate - to reconsideration, to the next review tier - rather than treating the first 'no' as final. Payers count on practices giving up after one attempt; we don't.

Root Cause Remediation

In parallel with the recovery work, we fix what's causing the denials: correcting recurring claim errors, tightening how coverage gets verified before visits, building tracking for services that need advance payer approval, and telling your clinicians exactly what documentation gaps keep costing money. Each fixed cause permanently removes a slice of future denial volume.

Ongoing Denial Prevention

Once the backlog is cleared and causes addressed, the system stays in place: claims screened before submission, new denials worked as they arrive, and monthly reporting that shows your denial rate trend. If a new pattern emerges - a payer changes a policy, a new procedure starts bouncing - it gets flagged and addressed in weeks, not discovered in a year-end review.

Getting Into Denial Management Claims

Understanding Denial Reason Categories for Effective Appeals

Every payer attaches a standardized reason to each claim it denies, reduces, or adjusts, and that reason is the single most important clue for how to respond. Mastering these denial categories is fundamental to effective denial management because the specific reason dictates the appropriate appeal strategy, required supporting documentation, and likelihood of overturn success.

The categories you will actually meet

• Missing or incomplete information
• Duplicate claims
• Filed past the timely-filing deadline
• Medical necessity
• Non-covered service
• Missing prior authorization

Each of these requires a fundamentally different response: missing-information denials typically need the complete data resubmitted within a specific timeframe; medical-necessity denials require a formal appeal with clinical documentation supporting the service; and no-authorization denials may need retroactive authorization requests or peer-to-peer reviews.

Practices that categorize denials by reason can identify systemic patterns: a high volume of missing-information denials suggests front-end claim scrubbing failures, while recurring medical-necessity denials may indicate documentation deficiencies or diagnosis selections that do not support the service.

• Missing-information denials indicate front-end claim scrubbing failures and are typically resolved by resubmitting with complete data within the payer-specific correction window.
• Medical-necessity denials require formal clinical appeals with supporting documentation; generic appeal letters without clinical evidence have low overturn rates.
• No-authorization denials may be recoverable through retroactive authorization requests or peer-to-peer reviews within the payer-specific retrospective auth window.
• Tracking denial patterns by reason category enables root cause identification; recurring patterns point to systemic process failures rather than isolated incidents.

The Appeal Is Usually Worth Making, and Almost Nobody Makes It

Two federal datasets, measured in completely different ways, land on the same conclusion.

KFF analyzed the federal Transparency in Coverage filings and found that marketplace insurers denied 19% of in-network claims in 2024, in a range from 3% to 36% depending on the insurer. Of roughly 85 million denied claims, consumers appealed fewer than 1%. Of the appeals that were filed, insurers upheld 66%, so about one in three appealed denials was reversed.

The federal audit of Medicare Advantage is starker. The HHS Office of Inspector General reviewed skilled nursing prior authorization denials across 19 plans in June 2024 and found that plans overturned 95% of appealed denials in favor of the enrollee, while only 18% of denials were appealed at all. A companion audit found long-term acute care denials overturned 36% of the time and inpatient rehabilitation denials 43%, with the inpatient rehab rate ranging from 14% to 86% depending on which plan issued the denial.

That spread is the tell. When one plan reverses 14% of its own denials on appeal and another reverses 86%, the denial is not tracking a consistent clinical standard. OIG attributed the highest denial rates to contractors deciding on the plans' behalf, later reversed by the plan itself once someone pushed back.

What this means for a practice

• A denial is a first position, not a final answer, and the reversal rates say so plainly.
• The economics favor appealing far more often than practices actually do.
• Nobody appeals claims that were never worked, which is why denial follow-up has to be somebody's standing job rather than what happens when there is time.

OIG put it in its own words: a 95% overturn rate "raises concerns about denials that were not appealed."

• Marketplace insurers denied 19% of in-network claims in 2024, ranging from 3% to 36% by insurer (KFF analysis of CMS Transparency in Coverage data)
• Fewer than 1% of those denials were appealed, and insurers upheld 66% of the appeals that were filed
• Medicare Advantage plans overturned 95% of appealed skilled nursing denials, but only 18% of those denials were ever appealed (HHS OIG, OEI-09-24-00331, June 2024 data)
• Inpatient rehabilitation overturn rates ranged from 14% to 86% depending on the plan (HHS OIG, OEI-09-24-00330)

Reconsideration vs. Formal Appeal: Choosing the Right Strategy

Healthcare providers often conflate reconsiderations and formal appeals, but these are distinct processes with different requirements, timelines, and implications. A reconsideration is an informal request to re-examine a claim, typically used when a claim was denied due to a correctable error such as missing information, incorrect coding, or data entry mistakes.

Reconsiderations generally do not require extensive clinical documentation and can often be resolved by resubmitting the claim with corrections or providing the specific missing data element identified in the denial.

A formal appeal is a different instrument

It is a structured challenge to a payer's coverage or medical necessity determination, governed by filing deadlines, required documentation formats and defined levels of review.

For Medicare claims, the appeals process follows five distinct levels: redetermination by the MAC (120 days), reconsideration by a Qualified Independent Contractor (180 days), hearing before an Administrative Law Judge for claims exceeding $180 (60 days), Medicare Appeals Council review (60 days), and federal district court judicial review for claims exceeding $1,760.

Commercial payer appeals typically have two internal levels followed by external review through an Independent Review Organization (IRO). Understanding which pathway to pursue is critical because filing a formal appeal when a simple reconsideration would suffice wastes resources and delays resolution, while treating a medical necessity determination as a correctable error misses the substantive clinical argument needed to overturn the denial.

• Reconsiderations address correctable errors (missing data, coding mistakes) and typically resolve within 30 days; formal appeals challenge coverage or medical necessity determinations and follow structured timelines.
• Medicare appeals have five defined levels with specific filing deadlines at each stage; missing a deadline forfeits the right to appeal at that level and all subsequent levels.
• Commercial payer appeals typically allow two internal levels before external IRO review; state insurance department complaints can be filed concurrently to create additional pressure.
• Approximately 40% of initial denials can be resolved through simple reconsiderations rather than formal appeals, significantly reducing the time and resources needed for recovery.

Underpayment Identification and Recovery Strategies

Underpayments represent a substantial but often overlooked category of revenue leakage that differs from outright denials in that the claim is paid, but at a rate lower than the contracted amount. Underpayments are easy to miss precisely because the claim comes back marked paid, so nothing flags for follow-up and the shortfall compounds quietly.

Identifying underpayments requires systematic comparison of actual payments against contracted fee schedules for every claim, which most practice management systems can automate through payment variance reporting.

• Payer system errors applying the contracted rate
• Multiple-procedure payment-reduction rules applied incorrectly
• Separately payable services bundled together
• Visit or procedure levels downcoded without clinical justification
• Negotiated rate increases not applied on the contractual effective date

The distinction between underpayments and legitimate payment adjustments is critical.

Contractual adjustments, co-pay/deductible allocations, and coordination of benefits reductions are not underpayments, while payment amounts below the contracted fee schedule rate for a covered service are actionable.

Recovery typically means filing a payment dispute or reconsideration with the payer, providing the contract terms and demonstrating the shortfall. Most payer contracts include a payment dispute window of 60-120 days from the remittance date, making timely identification essential. Practices that implement automated underpayment detection as part of their standard posting workflow recover significantly more revenue than those relying on periodic manual review.

• Paid does not mean paid correctly, and underpaid claims are easy to miss; automated payment variance reporting against contracted fee schedules is essential for detection.
• Common underpayment causes include payer system errors, incorrect multiple-procedure reductions, improper bundling, unauthorized downcoding, and failure to apply negotiated rate increases.
• Payment dispute windows are typically 60-120 days from remittance date; underpayments identified after the dispute window may be permanently unrecoverable.
• Automated underpayment detection integrated into the payment posting workflow identifies issues in real-time rather than through periodic manual reviews that miss dispute deadlines.

What Each Payer Expects

Medicare (Traditional Fee-for-Service)

• Medicare redetermination requests must be filed within 120 days of the initial determination date. Submit the redetermination request in writing with a clear statement of disagreement and all supporting clinical documentation.
• Medicare claims denied for medical necessity should include the relevant local and national coverage policy citations in the appeal, demonstrating that the service meets established coverage criteria. Reference the specific coverage policy and covered indication.
• Duplicate-claim denials on Medicare are common when resubmitting corrected claims. Clearly flag the resubmission as a replacement or corrected claim to prevent it from being rejected as a duplicate.
• Medicare timely filing is 12 months from the date of service, but appeals of denied claims have separate deadlines at each appeal level. Track both the original filing deadline and each appeal-level deadline independently.

Medicare Advantage Plans

• Medicare Advantage denial rates are 30-40% higher than traditional Medicare for the same services. MA plans frequently deny claims for lack of prior authorization on services that traditional Medicare covers without pre-approval.
• MA plan appeals must follow the specific plan's internal process before accessing the external Medicare appeals system. Exhaust both internal appeal levels within the plan's specified timeframes before requesting an IRE (Independent Review Entity) review.
• Expedited appeals for urgent services must be decided within 72 hours by MA plans. Request expedited review when a standard appeal timeline could jeopardize the patient's health or ability to regain maximum function.
• MA plans that deny coverage must provide a written Organization Determination explaining the denial reason, appeal rights, and filing deadlines. If this notice is missing or incomplete, file a complaint with CMS which can trigger immediate plan compliance review.

Commercial Payers (UnitedHealthcare, Aetna, Cigna)

• Commercial payer appeal deadlines vary significantly: UnitedHealthcare allows 180 days for most appeals, Aetna allows 180 days, and Cigna typically allows 365 days. Verify the specific deadline on each Explanation of Benefits (EOB) rather than relying on general guidelines.
• Peer-to-peer reviews are often available for medical necessity denials from commercial payers. Requesting a peer-to-peer conversation between the treating physician and the payer's medical director can overturn denials that written appeals cannot.
• State insurance department external review is available for commercial payer denials after internal appeals are exhausted. External review decisions are binding on the payer in most states and have overturn rates of 40-60% for medical necessity denials.
• Commercial payers increasingly use automated clinical editing software that auto-denies based on how services are combined on a claim. Understanding which payer bundling rules trigger auto-denials enables front-end correction before claim submission.

All Payers (General Denial Management Best Practices)

• Implement a denial management dashboard that tracks denials by payer, denial reason category, service type, and provider. Monthly trending reveals systemic issues that can be addressed through process improvement rather than individual claim rework.
• Set automated alerts for appeal deadline tracking with escalation at 30-day, 15-day, and 5-day intervals before each filing deadline. Lost appeal rights due to missed deadlines represent permanent, unrecoverable revenue loss.
• Maintain a payer-specific appeal template library with pre-built clinical arguments for the most common denial reasons. Customized templates with clinical evidence overturn denials at 3-4x the rate of generic form letters.
• Track denial overturn rates by appeal writer and strategy to identify which approaches are most effective for each payer and denial type. Use this data to continuously refine appeal strategies and allocate resources to the highest-value recovery opportunities.

Questions we get asked

What is the difference between a rejection and a denial?

A rejection never reached the payer's adjudication system, usually stopped at the clearinghouse for a formatting or data problem. A denial was adjudicated and refused. Rejections are cheaper and faster to fix, and are the ones most often lost because nothing appears on an aging report.

Is it worth appealing small denials?

Often yes, because the value is not only the single claim. A denial worked and logged tells you which upstream step produced it, and fixing that step is what stops the next fifty. Appeal economics alone would say ignore small claims; pattern economics say otherwise.

How long do we have to appeal?

Every payer sets its own window, and they differ widely. The practical risk is not one missed deadline but a backlog quietly ageing past several at once, which is why aged claims get worked oldest-first rather than by size.

What causes most denials?

Two categories come up again and again: eligibility and authorization problems created before the visit, and documentation that does not support what was billed. Both originate upstream of billing, which is why denial work that never reports causes back to intake keeps producing the same denials.

Can you work denials we have already written off?

Sometimes, depending on how old they are and each payer's filing limits. It is worth reviewing before writing anything off permanently, because written-off claims never appear in any report and so never get counted as a loss.
