Claim Denial Resolution
A denial is not a dead end. It's a decision waiting to be reversed.
Where a denial-management program watches the whole portfolio, this work goes the other direction — down into the individual claim. We read the remittance line by line, find why this claim was truly denied, choose the path that this payer actually rewards, and assemble a rebuttal that leaves the adjudicator no room to say no again.

01Down into the individual claim
Where a single denied claim ties up your cash
Reversing a denial takes something a busy front desk rarely has: the time to read the remittance line by line, pull the operative note or the authorization number, match the payer's own medical policy against the denial reason, and assemble a rebuttal that leaves the adjudicator no room to say no again. Skip any of those steps and the resubmission bounces a second time, the clock keeps running, and a claim you fully earned quietly ages past timely filing into a permanent write-off.
Four questions decide whether the dollars come back
Getting all four right on each denied claim is the difference between recovery that produces cash and a resubmission habit that produces nothing but more denials.
Question 01Why was this specific claim denied, really — beyond the surface reason code?
Question 02Is the fastest path a corrected claim or a formal appeal?
Question 03Which one does this particular payer actually reward?
Question 04What evidence does its policy require, and what is the exact deadline?
A prior-auth denial may actually be a demographic mismatch; a "not covered" may be a coordination-of-benefits sequencing error.
What the pile looks like
UNWINNABLE
The assumption behind every abandoned denial — that the payer was right, or that the fight was not worth having.
What it usually is
UNWORKED
Set aside because no one had the hours to run a proper denial analysis and no one was fluent in the appealing payer's rules.
When you hand those claims to specialists who do nothing else, the write-off pile shrinks and the money you already earned by delivering care finally lands in your account.
02We do not batch-resubmit and hope
What our claim denial resolution recovers, claim by claim
We diagnose each denial by its true root cause, choose the correct recovery path for that payer, and document the appeal so it holds. The reason codes below only illustrate how we classify a claim on intake — your staff never has to touch them.
| Denial reason on the claim | Representative codes | How we resolve that specific claim |
|---|---|---|
| Coverage / patient not eligible | CARC 27, 31; RARC N30 | Trace correct plan, rebill active coverage, appeal with eligibility proof |
| No prior authorization on file | CARC 197; RARC N54 | Retro-authorization request, medical-necessity packet, corrected-claim resubmission |
| Bundling / modifier / coding | CARC 4, 11, 16; RARC M51 | Certified-coder re-review, modifier correction, appeal with code rationale |
| Medical necessity not met | CARC 50, 55; RARC N115 | Attach clinical notes, cite the payer's own LCD/NCD policy, formal appeal |
| Timely filing exceeded | CARC 29; RARC N211 | Produce clearinghouse proof of original filing, submit override request |
| Duplicate / coordination of benefits | CARC 18, 22; RARC N598 | Correct primary/secondary sequence, update COB, resubmit clean |
| Underpayment vs. contract | CARC 45; RARC N517 | Compare to fee schedule, appeal the shortfall with contract language |
03Investigator, coder and litigator at once
Outsource claim denial resolution to specialists who read payer policy for a living
A rare mix
Winning a single appeal well demands a rare mix: an analyst who can find the real reason behind a vague denial code, a coder who can defend the procedure on the record, and an appeal writer who speaks the appealing payer's exact medical-policy language. Few practices can staff all three for the handful of complex denials that carry the most dollars. When you outsource this work to a specialist billing company, you stop asking one overloaded biller to be an investigator, a coder, and a litigator at once.
Where it matters most
As a full-service medical billing services company, we put certified AAPC and AHIMA coders, RCM analysts, and payer-specialized appeal writers on every case together. That matters most on the high-dollar, high-friction denials — surgical bundling disputes, medical-necessity rejections on advanced imaging, retro-authorization fights — where a generic resubmission fails and a policy-cited, evidence-backed appeal wins.
The quieter return
When your best billers stop grinding through complex appeals, they get their hours back for the upstream work — verifying benefits before the next schedule, posting payments faster, answering patient-balance calls. Reassigning appeals to a specialist partner reclaims internal capacity you already pay for. That is the real economics of choosing to outsource denied-claim work: you are not just buying recovery labor, you are freeing the team you have.

04One owner, one measurable outcome
How we work a denied claim from receipt to overturn
Every denial we accept moves through a defined path with one owner and one measurable outcome — money recovered or a documented reason it could not be. This is the case-level companion to the ongoing denial management services program; use them together and the same denial stops coming back.
- 01Triage
Intake & triage
We log the denial the moment it posts, capture the CARC/RARC reason, and rank it by dollar value and days left to the timely-filing or appeal deadline — so the claims most at risk of aging out get worked first.
- 02Diagnose
Root-cause analysis
We go past the surface reason code and read the full remittance, the original claim, and the clinical record to find why this claim was truly denied. Accurate denial analysis is what makes the fix stick.
- 03Choose
Decide the path
If a data or coding error caused the denial and a fix will clear it, we submit a corrected claim for the fastest turnaround. If the payer is wrong on policy or medical necessity, we escalate to a formal appeal. Choosing correctly per payer is where recovery is won or lost.
- 04Build
Build the packet
For appeals, we assemble an appeal letter that cites the payer's own policy, the operative or progress notes that prove necessity, corrected coding from our medical coding services coders, and proof of eligibility or timely filing where relevant.
- 05Escalate
Submit, track & escalate
We file to the right level and address, confirm receipt, and track to resolution — escalating to second-level and external review when a wrongful denial is upheld. Recovered dollars flow into your A/R follow-up workqueue and your free dashboard, inside the full revenue cycle management picture.
05Lost on execution, not on the merits
The appeal failures we eliminate
Most lost appeals are not lost on the merits — they are lost on execution. These are the specific failure points that turn a winnable denied claim into a write-off, and how we remove each one.

06The reversals hold up
Why providers trust 247MBS to overturn denials
Built to win the claims a generalist would abandon.
Providers bring us their hardest denials because the reversals hold up. Our claim denial resolution services sit inside an operation that runs a 99% clean-claim rate, roughly 99% net collection, first submissions within 24 hours, and accounts receivable held under 25 days. On workable denials, our recovery approach targets up to 90% — and the appeals that succeed are the high-dollar ones that move a practice's month. Behind every appeal is a compliance and expertise foundation you can defend to any auditor. We are HIPAA-compliant and SOC 2 Type II-certified, an HBMA member, and staffed with AAPC and AHIMA-certified coders whose reviews give each appeal genuine clinical weight. A 98% client-retention rate across 20-plus years since 2005 is what happens when a partner treats a denied claim as recoverable revenue instead of paperwork to file and forget.

07On a single high-dollar denial
Case-level specialists vs. a generalist resubmitter
A generalist resubmits the claim and moves on. A denial-resolution specialist investigates it, chooses the winning path, and documents the appeal to overturn it. On a single high-dollar denial, that difference is the whole recovery:

08Written in the language its payer respects
Who we win appeals for
We resolve denied claims for solo practitioners, group practices, multi-specialty clinics, ambulatory surgery centers, and hospital-affiliated groups across behavioral health, anesthesia, urgent care, primary care, pain management, and more. Because our coders and analysts are specialty-aligned, your appeals are written by people who already know the payer policies governing your procedures.
Pain-management groups
Interventional medical-necessity denials, where the appeal has to argue the procedure against the payer's own coverage policy.
What wins the appealPolicy-cited necessity argument
Primary-care panels
Coverage and coordination-of-benefits denials, which need a very different appeal — and often just the correct sequence.
What wins the appealCorrect COB sequencing
Surgical & imaging disputes
Bundling disputes and medical-necessity rejections on advanced imaging, where a generic resubmission fails outright.
What wins the appealEvidence-backed code rationale
Specific high-dollar backlogs
Some practices come to us with a backlog of high-dollar denials they cannot afford to lose; others fold case-level resolution into a broader engagement.
What wins the appealGetting to it before the deadline
Either way, the work scales to your claim volume and payer mix, and you keep full visibility into every case from intake to outcome.
09No long ramp
Getting started on your denied-claim backlog
Onboarding is deliberately low-lift — we connect, analyze, and start winning claims back.
We review the open denials
After the revenue review we go through your open denials and rank what is still recoverable.
Read-and-work mode
We connect to your practice-management system and clearinghouse in read-and-work mode — there is no software to replace.
Deadline-critical first
Within the first cycles we are filing corrected claims and appeals on the denials most at risk of aging out.
Your dedicated account manager reviews recovered dollars and overturn rates with you on a set cadence.
Claim denial resolution services are the case-level work of recovering a specific denied claim: deep root-cause analysis of why it was denied, the decision between a corrected claim and a formal appeal, and a payer-specific appeal packet built to overturn the denial before its deadline. It is claim-by-claim recovery, not portfolio-level prevention.
This page is the worked-claim and appeals service — deep analysis and resolution of individual denied claims. Our denial management services page is the ongoing program that trends denial patterns and prevents them upstream. Most clients use both: resolution wins back today's claims, management stops tomorrow's.
Yes. The first thing we decide on each claim is which path wins it. If a data or coding fix will clear the denial, we file a corrected claim for speed. If the payer is wrong on policy or medical necessity, we build and submit a formal, policy-cited appeal — and escalate to reconsideration or external review if it is upheld.
Often, yes — as long as the appeal or timely-filing window is still open, and sometimes even after, with proof of original submission. We triage by deadline first, so aging high-dollar denials get worked before they are lost for good.
No. We work inside your existing practice-management and clearinghouse systems in read-and-work mode. There is no rip-and-replace to begin recovering your denied claims.
Fully. We are HIPAA-compliant and SOC 2 Type II-certified, with strict access controls and audit logging across every appeal and workflow.
