Out-of-Network Billing Solutions

The OON Challenge
Challenges Facing O-O-N Providers Today
If any of these describe your practice, Revix MD was designed to solve exactly these problems.
Chronic Underpayments
Payers routinely process out-of-network claims at rates far below UCR. Without a structured underpayment analysis workflow, practices leave substantial revenue uncollected every month.
High Denial Rates
Out-of-network claims attract disproportionate scrutiny. Without proactive denial management and clean claim submission protocols, rejection rates compound quickly.
Stalled A/R
Aging accounts receivable tied up in appeals or awaiting payer response directly erodes cash flow and most OON providers don’t have the infrastructure for aggressive A/R follow-up.
BCBS Complexity
Blue Cross Blue Shield plans operate under highly variable state and regional policies. Without BCBS-specific billing workflows and institutional payer knowledge, claims stall or underpay.
Coding Gaps
Errors in CPT or ICD coding even minor ones – trigger automatic denials. OON billing leaves no margin for coding inaccuracies; payer policy compliance must be exact.
Front-Desk Leakage
Incomplete insurance eligibility verification and benefits verification upstream translates into preventable denials downstream. Front-end accuracy is non-negotiable.
Core Services
Full-Cycle Out-of-Network Billing & Reimbursement Services Built Around Your Practice
Our OON billing services cover every touchpoint from patient intake through final reimbursement – leaving no revenue stage unmanaged.
Insurance Verification & Eligibility
Real-time benefits verification with payer-specific OON benefit extraction, coordination of benefits review and patient responsibility estimation before service delivery.
Prior Authorization Support
Structured prior authorization tracking with payer-specific documentation requirements, reducing authorization-related denials before they occur.
Clean Claim Submission
Claims are processed through a multi-layer claim scrubbing workflow with clearinghouse integration to identify errors before submission, helping improve first-pass claim acceptance and reduce preventable rejections.
Denial Management & Appeals
Systematic denial trend analysis with payer-specific appeals optimization. Each denial receives root-cause analysis and a response strategy tailored to that payer’s review protocols.
A/R Recovery & Follow-Up
Aggressive accounts receivable recovery with dedicated payer follow-up schedules, ERA/EFT reconciliation and escalation workflows for unresponsive payers.
Underpayment Analysis & Auditing
Fee schedule analysis against payer-paid amounts identifies systematic underpayments. We pursue recoupment on shortfalls through structured out-of-network reimbursement auditing processes.
Advanced Out-of-Network Reimbursement Capabilities
Beyond standard claims billing, Revix MD deploys the full toolkit of out-of-network revenue strategies that most billing firms simply don’t offer.
UCR Benchmarking & FAIR Health Analysis
Usual, Customary, and Reasonable (UCR) rate benchmarking is the primary lever for maximizing OON reimbursement. We use FAIR Health – the standard independent database for OON reimbursement benchmarking to challenge underpayments and substantiate UCR claims with payers. When payers pay below UCR, we have the data and the process to dispute it.
Single-Case Agreements (SCAs)
For surgery centers and high-acuity specialty practices, single-case agreements represent one of the most effective OON revenue tools available. We negotiate SCAs directly with payers on your behalf – securing a pre-agreed rate for specific patients before services are rendered, eliminating post-service payment uncertainty on complex cases.
Gap Exceptions & Letters of Agreement
When no in-network provider is available to meet patient need, payers are often required to consider gap exceptions – reimbursing an OON provider at in-network rates. We identify when gap exceptions apply, prepare the necessary documentation, and pursue letters of agreement that protect your patients and your revenue.
IDR Representation (No Surprises Act)
For NSA-protected claims, the Independent Dispute Resolution (IDR) process is one of the most powerful post-payment recovery tools available to OON providers today. Our team manages the full IDR workflow, eligibility assessment, open negotiation, arbitration submission and follow-through turning regulatory complexity into a recoverable revenue stream.
Payer Negotiation & Escalation
Payer negotiation is a dedicated capability at Revix MD – not a footnote. For underpayment disputes, open negotiation periods and chronic underpayment patterns, we engage payers directly with documented UCR comparisons, FAIR Health data and escalation pathways specific to each carrier. We know when to escalate and how.
Patient Balance Billing Strategy
OON billing creates real patient balance considerations that have to be handled carefully – both for the patient relationship and for NSA compliance. We advise on balance billing strategy, manage patient financial communications and ensure your practice stays compliant with federal and state balance billing restrictions while still collecting what you are owed.
We Recover Revenue at Every Stage of the Billing Cycle
Revenue cycle performance is determined at both ends of the claim lifecycle. Revix MD manages both with equal rigor.

Revix MD integrates natively with the major EHR and practice management platforms used by U.S. healthcare providers. Rather than forcing workflow disruption during onboarding, our billing infrastructure connects to your existing systems – preserving scheduling continuity, clinical documentation flows and data integrity.

Why Revix MD
Built for Practices That Cannot Afford to Under-Collect
Specialty providers operating out-of-network run on thin operational margins where every unpursued claim or underpaid remittance has a real bottom-line impact. Revix MD operates as a strategic revenue cycle partner – not just a claims processing vendor.
OON-Dedicated Specialists
Our billing team works exclusively on out-of-network accounts. This focus produces deeper payer knowledge and faster denial resolution than generalist billing departments.
Payer-Specific Workflow Libraries
We have built and refined payer-specific workflows for BCBS, Aetna, Cigna, UHC and regional carriers – covering documentation requirements, appeal timelines and escalation paths.
Revenue Leakage Prevention
From front-desk intake accuracy through ERA reconciliation, we close the gaps where practices commonly experience silent revenue leakage.
Transparent Monthly Reporting
Practices receive detailed monthly reports covering collection rates, denial trends, A/R aging and payer-level performance – giving leadership full revenue visibility.
No Surprises Act Compliance
Our billing operations are structured to comply with evolving NSA requirements – including IDR representation, Good Faith Estimate protocols and balance billing compliance, protecting your practice from regulatory exposure while preserving reimbursement rights.
HIPAA & SOC 2 Type II
We operate under both HIPAA-compliant data handling protocols and SOC 2 Type II certification, the standard for service organizations handling protected health information. Your patient data is secure at every stage.

FAQs
What makes out-of-network billing different from standard medical billing?
Out-of-network billing involves submitting claims to payers without a contracted rate, which introduces unique challenges: variable reimbursement calculations tied to UCR methodology and FAIR Health benchmarks, higher denial rates, more complex appeals processes, and frequent underpayments. It also requires deep knowledge of payer-specific OON benefit structures, single-case agreement negotiation, IDR representation under the No Surprises Act and gap exception handling. Standard billing companies rarely have the specialized workflows OON billing requires.
How does Revix MD use UCR benchmarking and FAIR Health data?
Usual, Customary, and Reasonable (UCR) rate benchmarking is central to how we challenge underpayments. FAIR Health is the independent, nationally recognized database payers, providers and regulators rely on for OON reimbursement benchmarking. We use FAIR Health data to document the gap between what a payer paid and what the claim warranted and we use that documentation to formally dispute underpayments through appeals, open negotiation and where applicable, the federal IDR process.
What are Single-Case Agreements and when do you pursue them?
A Single-Case Agreement (SCA) is a one-time negotiated rate between a provider and a payer for a specific patient’s care – typically used for high-cost, complex procedures where post-service payment uncertainty is a real risk. We pursue SCAs proactively for surgery centers and specialty practices when the case warrants it, securing a written commitment from the payer before services are delivered. This is one of the most effective OON revenue tools available and one most billing vendors simply don’t offer.
How does Revix MD handle BCBS out-of-network claims?
BCBS billing requires plan-specific expertise because reimbursement policies vary significantly across state affiliates and employer group plans. We maintain dedicated BCBS follow-up workflows, monitor BCBS-specific denial trends and have established escalation pathways for underpayment disputes. Our clients see an average 37% reduction in BCBS Days in A/R within 90 days of go-live.
Is Revix MD compliant with the No Surprises Act?
Yes. Our billing operations are structured around NSA requirements, including Good Faith Estimate protocols, Independent Dispute Resolution eligibility assessments, required patient communications and balance billing compliance. We also provide active IDR representation for eligible claims – not just eligibility review, but end-to-end management through the federal arbitration process. We monitor regulatory updates and adapt our workflows as federal and state guidance evolves.
How long does the onboarding process take?
Most practices are fully onboarded with EHR integration, payer credentialing review and initial claims submission within 30 days. Our implementation team manages the technical setup, data migration and workflow configuration so your clinical staff experiences minimal disruption.
What does the revenue assessment include?
Our free revenue assessment includes a review of your current out-of-network claims submission process, A/R aging analysis, denial rate benchmarking against industry standards, payer mix evaluation and a candid assessment of where revenue leakage is occurring – including whether you have opportunities for SCA negotiation, gap exceptions or IDR recovery. There is no obligation – the goal is to give you an honest picture of your OON revenue performance and where improvement is possible.
