End-to-End Denial Resolution From Root-Cause Audit to Final Reimbursement
Up to 65% of denied healthcare claims are never reworked by busy in-house teams. Doc Flow RCM combines certified medical coders and appeal specialists to fight every unpaid claim.
Same-Day Rejection Fixes
We resolve 277CA front-end clearinghouse and payer scrub rejections within 24 hours so clean claims enter payer adjudication queues immediately.
Coding & NCCI Edit Rebuttals
Our AAPC/AHIMA-certified coders review clinical notes to correct CPT/ICD-10 mismatches, unbundling edits (CO-97/CO-59), and missing modifiers (25, 59, XU).
Medical Necessity Appeals
For CO-50 and LCD/NCD medical necessity denials, we draft evidence-based appeal letters backed by operative reports, chart notes, and payer policy citations.
Prior Auth & Retro Appeals
We fight CO-197 authorization denials by matching existing auth numbers, pursuing retroactive authorizations, or appealing urgent/emergent care exceptions.
Timely Filing Overturns
When claims deny for CO-29 (Timely Filing Limit), we pull clearinghouse 277CA acceptance logs and electronic submission trails to prove on-time filing.
Underpayment & Fee Audits
We audit partial payments against your contracted payer fee schedules and file formal reconsiderations when payers reimburse below contracted rates.
Denial Prevention Analytics
We deliver monthly denial trend reports to fix front-desk registration, eligibility, and clinical documentation gaps so denials stop happening in the first place.
How Our Denial Management & Appeals Process Works
Every denied claim is captured on the day the ERA posts, routed to a specialized resolution queue, and pursued until full reimbursement is recovered.
01
Daily ERA & EOB Capture
Zero-pay claims and partial denials are flagged automatically from daily 835 ERAs and paper EOBs.
02
CARC/RARC Categorization
Claims are sorted by denial type, dollar value, payer timely filing deadline, and soft vs. hard denial status.
03
Clinical & Coding Review
Certified coders examine EHR chart notes, modifiers, LCD guidelines, and patient eligibility records.
04
Corrected Claim or Appeal
We transmit corrected 837 claims (Frequency Code 7) or submit formal Level 1 & Level 2 clinical appeal packets.
05
Payer Escalation & Tracking
Our A/R specialists follow up via payer portals and phone calls every 14 days until the claim reprocesses.
06
Root-Cause Elimination
We update clearinghouse scrub rules and train front-end staff to prevent recurring denial patterns.
Major Claim Denial Categories We Overturn Across All Payers
Generic form letters rarely overturn complex insurance denials. We tailor every corrected claim and clinical appeal to the specific CARC/RARC denial reason code.
1. Front-End Eligibility & Registration Denials
- ✓CO-27 (Coverage Terminated): Retroactive policy discovery and alternative active coverage search
- ✓CO-22 (Coordination of Benefits): Primary EOB attachment and secondary crossover billing
- ✓CO-16 / MA130 (Missing Info): Rapid demographic, subscriber ID, and referring NPI corrections
- ✓CO-109 (Wrong Payer): Identification of correct Medicare Advantage or Managed Medicaid plan
2. Coding, Bundling & Modifier Denials
- ✓CO-97 / CO-59 (Bundled Services): NCCI edit reviews and distinct procedural service documentation
- ✓CO-4 / CO-11 (Modifier & DX Errors): Proper application of Modifiers 25, 26, 59, 76, 79, LT/RT, and JW/JZ
- ✓CO-151 (Frequency Limits): Medical necessity justification for exceeded units or visits
- ✓Global Period Denials: Unrelated E/M or staged procedure documentation during post-op windows
3. Prior Authorization & Medical Necessity
- ✓CO-197 (Missing Prior Auth): Auth number linkage, retro-auth submissions, and urgent care appeals
- ✓CO-50 (Not Medically Necessary): Clinical appeals citing CMS LCD/NCD guidelines and chart notes
- ✓CO-252 (Missing Medical Records): Immediate submission of operative notes, labs, and imaging reports
- ✓CO-96 (Non-Covered Charges): Policy exception reviews and accurate patient responsibility transfer
4. Timely Filing, Duplicates & Credentialing
- ✓CO-29 (Timely Filing Expired): Appeals backed by clearinghouse acceptance reports and timely primary EOBs
- ✓CO-18 (Duplicate Claim): Proof of distinct multiple encounters, repeat procedures, or bilateral services
- ✓CO-185 / B7 (Provider Enrollment): Resolution of rendering vs. billing NPI and taxonomy mismatches
- ✓CO-45 (Contractual Underpayments): Payer fee schedule variance disputes and repricing demands
How Proactive Denial Management Protects Your Practice Revenue & Profitability
Industry studies show practices lose 5% to 10% of their net annual revenue to unworked denials and premature write-offs. See how our dedicated recovery desk changes the outcome.
Reactive / Unmanaged Denials
Why practices lose thousands each month to preventable write-offs
- Billers simply re-submit the exact same claim without fixing the underlying error, triggering CO-18 duplicate denials
- Complex clinical and medical necessity denials sit untouched until timely appeal windows expire
- Staff write off recoverable balances as "Contractual Adjustments" just to clear their work queues
- No feedback loop to the front desk or coders—causing the exact same denials to repeat every week
- Aging A/R over 90+ days balloons while practice cash flow becomes unpredictable

Frequently Asked Questions About Denial Management Services
Clear answers on how Doc Flow RCM overturns denied claims and prevents future revenue leakage.
Q1. What is the difference between a claim rejection and a claim denial?
A claim rejection occurs at the clearinghouse or payer front-door (via 277CA) due to missing demographics, invalid subscriber IDs, or formatting errors before the payer ever adjudicates the claim. A claim denial occurs after the payer processes the claim and refuses payment on the 835 ERA/EOB due to medical necessity, missing prior auth, bundling, or coverage rules. We resolve both within 24 to 48 hours.
Q2. How quickly does your team work newly denied claims?
Clearinghouse rejections are corrected and resubmitted within 24 hours. Payer ERA/EOB denials are triaged and reworked within 24 to 48 hours of posting, ensuring corrected claims and clinical appeals are submitted long before payer timely filing deadlines.
Q3. Can you recover our existing backlog of 60, 90, and 120+ day denied claims?
Yes. When onboarding a new practice, we perform a comprehensive Old A/R and Denial Audit. We prioritize high-dollar claims and those approaching timely appeal deadlines first, systematically appealing and collecting revenue that would otherwise be written off.
Q4. How do you handle clinical and medical necessity (CO-50) appeals?
Our certified coders review the provider’s clinical progress notes, operative reports, diagnostic test results, and the payer’s specific Local Coverage Determination (LCD) or clinical policy bulletin. We then draft a customized Level 1 or Level 2 clinical appeal packet demonstrating why the procedure met medical necessity criteria.
Q5. How do you help our practice stop the same denials from happening repeatedly?
Reworking denials is only half the battle. Every month, we analyze your denial CARC/RARC trends by payer, provider, and CPT code. If we see front-desk eligibility errors, missing referrals, or recurring modifier issues, we update your clearinghouse rules and give your team actionable checklists to fix the root cause permanently.
