Out-of-Network Medical Billing Services

Accurate claim management is the foundation of proper out-of-network reimbursement.

Because OON claims are not based on negotiated payer contracts, reimbursement depends on accurate benefit verification, complete documentation, correct coding, proper claim submission, and consistent follow-up with insurance companies.

Without a dedicated OON billing process, practices can lose revenue through underpayments, denials, and missed appeal opportunities, not because the care was not provided, but because claims were not properly supported and managed.

MZ Medical Billing manages the complete out-of-network revenue cycle, from benefit verification and superbill preparation to claim submission, payment tracking, denial management, and appeals. Our OON specialists review reimbursement details, identify underpayments, handle payer follow-up, and help providers pursue appropriate payment for the services they provide.

We don’t measure OON success by claim volume submitted.

We measure it by reimbursement captured, denials addressed, and a healthier revenue cycle for your practice.

What Is Out-of-Network Medical Billing?

Out-of-network medical billing is the process of submitting and managing healthcare claims when a provider does not have a contracted agreement with a patient’s insurance company.

Unlike in-network providers, who agree to predetermined reimbursement rates through payer contracts, out-of-network providers do not have a negotiated fee schedule with the insurance plan. Instead, claims are submitted based on the provider’s billed charges, and the insurance company determines reimbursement according to the patient’s specific plan benefits, allowed amounts, and coverage rules.

Because there is no payer contract defining reimbursement rates, out-of-network billing requires careful claim preparation, accurate documentation, benefit verification, and ongoing follow-up. The amount a provider receives depends on several factors, including the patient’s out-of-network benefits, deductible status, coinsurance requirements, insurance plan policies, and how the claim is processed by the payer.

For many practices, OON billing provides greater control over pricing and allows providers to serve patients outside contracted networks. However, it also creates additional administrative responsibilities, including verifying benefits, preparing accurate superbills, tracking payments, reviewing underpayments, and appealing claims when reimbursement does not match the services provided.

Key Terms Providers Should Understand

Billed Charge

A billed charge is the amount a healthcare provider charges for a medical service or procedure. For out-of-network claims, the provider submits this charge to the insurance company for review.

The billed charge does not always equal the amount reimbursed by insurance. The payer reviews the claim based on the patient’s benefits, plan rules, and applicable reimbursement methods.

Allowed Amount

The allowed amount is the maximum amount an insurance plan recognizes as eligible for reimbursement for a specific service.

For in-network providers, the allowed amount is usually determined by the contracted payer agreement. For out-of-network providers, the allowed amount may be calculated using the insurance plan’s methodology, such as a percentage of a benchmark, UCR methodology, or other benefit provisions.

The difference between the provider’s billed charge and the insurance company’s allowed amount may affect the provider’s reimbursement and the patient’s financial responsibility.

UCR (Usual, Customary, and Reasonable) Rates

UCR refers to a method insurance companies may use to determine what they consider a reasonable reimbursement amount for out-of-network services.

UCR calculations may consider factors such as:

Geographic location
Historical charges for similar services
Provider specialty
Industry reimbursement data

Because UCR calculations vary between insurance plans, providers must carefully review reimbursement levels and payer methodologies to identify potential underpayments.

Patient Responsibility

Patient responsibility refers to the portion of healthcare costs that the patient may owe after insurance processes an out-of-network claim.

This may include:

Deductibles

The amount a patient must pay before insurance begins contributing toward covered services.

Coinsurance

The percentage of the allowed amount that the patient is responsible for after meeting the deductible.

Remaining Balance

The difference between the provider’s charge and the amount paid by insurance and the patient, when permitted under applicable laws and insurance plan requirements.

Understanding patient responsibility is important because OON claims often involve more complex billing expectations compared to in-network services.

Assignment of Benefits (AOB)

An Assignment of Benefits (AOB) is an authorization signed by the patient that allows insurance payments to be directed to the healthcare provider instead of being sent directly to the patient.

For out-of-network providers, AOB can help simplify reimbursement workflows by allowing the practice to receive payments directly from the insurance company when permitted by the patient’s plan and applicable regulations.

Without an AOB arrangement, some patients may receive insurance reimbursement first and then become responsible for paying the provider, which can create additional collection challenges.

In-Network vs Out-of-Network Medical Billing

Understanding the difference between in-network and out-of-network billing is important for providers deciding how they want to manage payer relationships, reimbursement expectations, and administrative requirements.

The primary difference comes down to the relationship between the provider and the insurance company. In-network providers have a signed agreement with the payer that establishes contracted reimbursement rates. Out-of-network providers do not have that agreement, which gives them more control over their billed charges but requires stronger billing processes to manage reimbursement.

Comparison Factor	In-Network Billing	Out-of-Network Billing
Payer Contract	Provider has a contract with the insurance company outlining reimbursement terms.	Provider does not have a contracted agreement with the insurance company.
Reimbursement Rates	Payment rates are based on negotiated payer agreements.	Reimbursement is determined by the patient’s benefits, payer policies, allowed amounts, and applicable reimbursement methods.
Provider Pricing Control	Provider accepts contracted rates established by the insurance company.	Provider has greater control over billed charges but must support claims with proper documentation.
Patient Responsibility	Patient costs are often more predictable due to contracted benefits.	Patient responsibility can vary based on deductibles, coinsurance, plan benefits, and applicable regulations.
Claim Management	Claims typically follow established payer contract requirements and workflows.	Claims often require more detailed verification, documentation review, follow-up, and appeal management.
Billing Complexity	Lower administrative complexity due to established payer agreements.	Requires additional attention to benefits, reimbursement calculations, claim tracking, and payer communication.

Key Difference for Providers

In-network billing offers more predictable reimbursement because payment rates are agreed upon before care is provided. However, providers must accept the limitations of contracted rates and payer requirements.

Out-of-network billing allows providers more flexibility over their charges and the ability to treat patients outside contracted networks. However, it requires a stronger revenue cycle process to verify benefits, submit accurate claims, monitor payer decisions, and address underpayments or denials.

For many out-of-network practices, successful reimbursement depends less on simply submitting claims and more on how effectively those claims are documented, managed, and followed through with insurance companies.

How Out-of-Network Medical Billing Works

Out-of-network medical billing starts before a claim is submitted and does not end when the claim reaches the insurance company. Every stage, from verifying benefits and preparing documentation to tracking payments and responding to denials, affects how the claim is processed and reimbursed. A missing modifier, incomplete documentation, or an unanswered payer request can delay payment or reduce reimbursement.

MZ Medical Billing manages each stage of the out-of-network billing process so claims are prepared, submitted, tracked, and followed through until they reach a final outcome.

Step 1: Verify Out-of-Network Benefits

The first step is confirming how the patient’s insurance plan handles out-of-network services before treatment takes place.

This includes reviewing:

Out-of-network benefits
Remaining deductible
Coinsurance and patient responsibility
Coverage exclusions and limitations
Prior authorization requirements, when applicable

Knowing this information before the visit reduces billing surprises and provides a clearer picture of how the claim will be processed.

Step 2: Review Clinical Documentation

Every claim is reviewed against the clinical record before billing begins.

The review includes:

Patient and provider information
Diagnosis documentation
Procedures performed
Medical necessity documentation
Supporting clinical records when required

Insurance companies rely on the documentation submitted with a claim. If the record does not support the services billed, reimbursement may be reduced or the claim may be denied.

Step 3: Prepare the Superbill and Claim

After documentation is reviewed, a complete superbill and CMS-1500 claim are prepared.

Each claim includes:

CPT procedure codes
ICD-10-CM diagnosis codes
HCPCS codes when applicable
Required modifiers
Provider and billing information

Claims are reviewed before submission to identify missing information that could lead to avoidable denials.

Step 4: Submit the Claim

Claims are submitted according to the insurance company’s filing requirements and deadlines.

Before submission, our team checks for:

Claim edits
Missing information
Payer-specific billing requirements
Filing deadline compliance

Submitting complete claims reduces delays caused by preventable errors.

Step 5: Track Payments and Resolve Claim Issues

Submitting a claim is only part of the billing process. Every out-of-network claim is monitored after submission until it is paid or reaches a final determination.

Our follow-up includes:

Payment posting
Review of underpayments
Status follow-up on delayed claims
Denial review
Appeal preparation and submission when appropriate

Claims that are underpaid or denied are reviewed to determine the reason for the payer’s decision and the next steps available under the applicable billing and appeal process.

Why OON Billing Is More Complex Than In-Network Billing

Out-of-network claims are reviewed differently than in-network claims. Since there is no contracted reimbursement rate between the provider and the insurance company, every claim depends on the patient’s benefits, the supporting documentation, payer guidelines, and the information submitted with the claim. Small errors that might have little impact on an in-network claim can significantly affect out-of-network reimbursement.

Underpayments and Reimbursement Reviews

Insurance companies determine out-of-network reimbursement according to the patient's benefits and the payer's reimbursement methodology. The amount paid may differ from the provider's billed charges because of plan limitations, allowed amounts, or how the claim was processed.

When payments are lower than expected, the claim should be reviewed to determine whether the reimbursement reflects the patient's benefits and the information submitted with the claim. Identifying underpayments early gives providers the opportunity to request a review or begin the appeal process when appropriate.

Claim Preparation and Documentation Issues

Out-of-network claims require complete and accurate billing information before they are submitted. Incorrect CPT or ICD-10-CM codes, missing modifiers, incomplete provider information, or documentation that does not support the services billed can delay processing or result in claim denials.

Reviewing claims before submission helps identify missing information and reduces avoidable billing errors that can affect reimbursement.

Delayed Follow-Up on Outstanding Claims

Submitting a claim does not guarantee that it will be processed or paid within the expected timeframe. Claims may remain pending because additional information is requested, payment is delayed, or the claim requires further review by the insurance company.

Without regular follow-up, aging claims can exceed appeal deadlines or remain unresolved for extended periods, increasing the likelihood of delayed reimbursement.

Patient Financial Responsibility

Out-of-network benefits vary from one insurance plan to another. Patients may have different deductibles, coinsurance obligations, reimbursement levels, and coverage limitations depending on their policy.

Verifying benefits before treatment and explaining potential financial responsibility helps patients understand their coverage and reduces billing questions after services have been provided.

Federal and State Billing Requirements

Out-of-network billing is also affected by federal and state regulations. The No Surprises Act established protections for certain out-of-network services and created requirements for provider billing, patient notices, and the Independent Dispute Resolution (IDR) process. Some states have additional balance billing laws that apply to specific healthcare services or insurance plans.

Practices that bill out-of-network claims need billing processes that take these requirements into account while following payer-specific submission and appeal guidelines.

What you get with MZ Medical Billing

With MZ Medical Billing, With MZ Medical Billing, each eligible out-of-network patient encounter is documented through an accurately prepared superbill and supporting claim documentation, reducing paperwork for your staff and helping claims move through the billing process efficiently. Every claim is tracked from submission until payment is received, while denied or underpaid claims are appealed until they are resolved. We bill every eligible claim in line with current No Surprises Act and AB 72 requirements, verify patient coverage before treatment to reduce denials, and provide a dedicated billing team that manages your out-of-network claims, so you always know where your revenue stands.

-Protecting your rate

Supporting Your Billed Charges

The whole advantage of being out-of-network is billing your own rate instead of a rate forced on you by an insurance contract. But that advantage disappears fast if your billing cannot back up the charge with clean documentation. Insurance companies look for any excuse to reduce a payout, and a weak claim gives them exactly that excuse.

Our billing process is designed to support appropriate reimbursement based on the services provided and supporting documentation. Every claim we submit carries the documentation needed to justify the amount billed, so payments come back closer to what you actually charged — not a reduced number the insurance company decided on its own. Over a year, this difference adds up to real revenue that most out-of-network practices are currently leaving behind

-Appeals

Denial recovery and appeals

Out-of-network claims get denied or underpaid far more often than in-network claims. Sometimes it is a coding issue. Some claims are denied because additional documentation is requested, coding needs clarification, or the payer determines that further review is required. Without timely follow-up, many underpaid or denied claims remain unresolved. Practices without a dedicated billing team almost always let it slide, because nobody has the time to fight a denial through multiple rounds of paperwork.

We do not let a denial end the conversation. Every rejected or underpaid claim gets reviewed, rebuilt with stronger documentation, and appealed until it is resolved fairly. This single service alone recovers thousands of dollars a year for practices that were writing off denied claims as a lost cause before working with us.

-Superbills

Superbill creation and management

The superbill is the document that decides whether your patient — and by extension your practice — gets paid back for out-of-network care. If it is missing a code, has the wrong date, or leaves out a detail the insurance company wants, the reimbursement stalls or gets denied outright. Building these by hand, visit after visit, eats up hours your front desk does not have.

We generate accurate superbills straight from your practice records for every out-of-network patient visit. Every code, every charge, every date lines up the way insurance companies expect it to. That means fewer phone calls from confused patients, fewer rejected reimbursements, and a faster payout cycle for everyone involved. Your staff stops spending their day on paperwork and goes back to running the front desk.

-Every specialty

Out-of-network billing across every specialty

Out-of-network billing does not work the same way for every specialty. A behavioral health claim needs different documentation than a surgical claim, and a diagnostic imaging claim gets reviewed by insurance companies in a completely different way than a physical therapy claim. Practices that use one generic billing process for every specialty end up with more denials than they should.

Our billing team builds claims around the specific coding and documentation rules of your specialty — not a one-size-fits-all template. Whether you run a solo practice or a multi-provider clinic, every claim reflects the exact requirements insurance companies expect to see for that type of care, which means fewer rejections and faster payments across the board.

After submission, claims are monitored for processing updates, additional payer requests, payment decisions, or issues that require further action. This allows unresolved claims to be identified and addressed before they become delayed or lost revenue.

COMPLIANCE & BILLING

When Out-of-Network Billing Is Normal — and When It Becomes a Surprise

Not every out-of-network claim carries risk. The difference comes down to one question: did the patient know what they were choosing?

Simply Normal

The Patient Chose to Go Out-of-Network

Most out-of-network billing is straightforward and expected. The patient knowingly chose an out-of-network provider, and both sides understand the arrangement from the start.

Provider bills their full rate, openly
Patient already knew this going in
Nothing about the bill is a surprise

Above board, start to finish.

Surprise Bill Risk

The Patient Never Knew

The patient is treated at an in-network facility, but the specific provider involved, an anesthesiologist, a radiologist, a specialist called into the case, is not in that network. No one told them.

Patient believed they were fully covered
They never agreed to an out-of-network provider
The bill catches them completely off guard

This is where special rules step in.

AB 72 No Surprises Act

Surprise billing situations are covered under specific rules, and billing them the wrong way risks disputes, delayed payment, and a patient who feels blindsided by your practice. We flag these cases early and bill them exactly the way the law requires, so your claim gets paid correctly and your patient never receives a bill they should not have gotten in the first place.

NETWORK STRATEGY

The Real Cost Difference: In-Network vs Out-of-Network

One path is locked into a contract. The other is billed at full value, defended by strong documentation. Here is what that difference actually looks like, visit after visit.

In-Network

Fixed, Contracted Rate

Full charge$120

Contracted rate$90

Insurance pays$70

Patient copay$20

The contract sets the ceiling. That gap is written off before the visit even happens.

Lost per visit −$30

Out-of-Network

Full Charge, Defended

Full charge$120

Contracted rateNone

Insurance paysPer OON benefit

Patient coversRemaining balance

No contract to cut the rate. The full charge stands, backed by documentation strong enough to hold it.

Revenue per visit Full $120

Where practices actually lose revenue

Higher out-of-network payouts only hold up when the billing behind them is airtight. Weak documentation is the only thing standing between your practice and that full charge — and closing that gap is exactly where we come in.

Staying Compliant With Out-of-Network Billing Rules

Out-of-network billing is affected by both federal and state requirements. Providers must understand when balance billing is allowed, when additional patient protections apply, and what documentation is required before billing a patient for out-of-network services.

MZ Medical Billing helps providers manage out-of-network claims while considering applicable billing requirements, payer rules, and compliance obligations that affect reimbursement.

No Surprises Act Compliance

The No Surprises Act (NSA) established federal protections against unexpected out-of-network medical bills in certain situations. While the law primarily focuses on protecting patients, it also affects how providers submit claims, communicate costs, and resolve payment disputes with insurance companies.

The No Surprises Act applies to situations including:

Emergency Services

Emergency services provided by out-of-network facilities or providers are generally protected under the No Surprises Act. Patients cannot be billed beyond the applicable in-network cost-sharing amount for covered emergency care.

Providers must follow the applicable claim submission and payment dispute processes when reimbursement disagreements occur.

Certain Out-of-Network Providers at In-Network Facilities

Patients may receive care at an in-network facility but still be treated by an out-of-network provider, such as:

Anesthesiologists
Radiologists
Emergency physicians
Pathologists
Other specialists involved in facility-based care

In these situations, additional billing protections may apply, and providers must follow the required notice and consent rules when applicable.

Notice and Consent Requirements

For certain scheduled out-of-network services, providers may be required to provide patients with a notice explaining their out-of-network status, expected charges, and available options before receiving consent to proceed.

Proper documentation of these notices and patient decisions is important when billing services that fall under federal surprise billing protections.

Independent Dispute Resolution (IDR)

When an out-of-network payment dispute occurs between a provider and insurance company, eligible claims may qualify for the federal Independent Dispute Resolution (IDR) process.

The IDR process allows both parties to submit information supporting their position, and an independent certified entity reviews the dispute and determines the appropriate payment amount according to applicable requirements.

State Balance Billing Requirements

In addition to federal requirements, many states have their own rules regarding surprise billing, balance billing, patient disclosures, and dispute resolution.

These requirements can vary based on:

State location
Type of healthcare service
Insurance plan
Provider setting
Patient coverage

Providers operating across multiple states must account for different billing requirements rather than applying a single process to every claim.

California AB 72

California’s AB 72 established protections against certain surprise medical bills involving out-of-network providers at in-network facilities. The law limits patient responsibility in covered situations and establishes payment rules between providers and health plans.

Florida Out-of-Network Billing Requirements

Florida has specific requirements related to balance billing disclosures, patient protections, and insurance claim practices. Providers must follow applicable state requirements when billing patients for out-of-network services.

New York Surprise Billing Protections

New York has additional protections for certain out-of-network healthcare services, including requirements related to patient disclosures and dispute resolution procedures.

Understanding federal and state requirements is an important part of managing out-of-network claims. MZ Medical Billing incorporates applicable billing rules into claim workflows, documentation review, and reimbursement follow-up to help providers handle OON billing responsibly.

Specialty-Specific Out-of-Network Billing Expertise

Out-of-network billing requirements vary across specialties because each type of care involves different documentation standards, coding requirements, authorization processes, and payer review criteria. MZ Medical Billing supports providers across behavioral health, physical therapy, cardiology, orthopedics, surgical practices, and other specialties with billing workflows based on the services provided and the reimbursement requirements involved.

Behavioral health billing requires careful review of therapy documentation, diagnosis coding, and payer requirements related to medical necessity. Physical therapy billing involves ongoing treatment plans, visit limits, authorization requirements, and detailed procedure documentation. Cardiology and orthopedic billing often involve complex procedures, diagnostic services, surgical care, and higher-value claims that require accurate CPT coding, modifier review, and supporting documentation.

MZ Medical Billing also supports surgical and specialty practices with complex claim preparation, documentation review, payment analysis, denial management, and appeals. By understanding the billing requirements associated with different specialties, our team helps providers submit claims that accurately reflect the services performed and addresses issues that may delay or reduce reimbursement.

Built around your practice, not the other way around

Nationwide out-of-network billing support

Insurance rules, deductibles, and out-of-network coverage limits shift from state to state, and even from plan to plan within the same state. A billing team that only understands one region's insurance landscape will miss details that cost your practice money in another. We work with out-of-network practices across the country, which means our billing team already understands the coverage patterns, common denial reasons, and state-specific billing laws tied to different insurance markets.

Transparent reporting, real-time visibility

Handing off your billing should not mean losing sight of your own revenue. A lot of practices avoid outsourcing because they are worried about losing control over what is happening with their claims. With MZ Medical Billing, you get clear reporting on every claim, every payment, and every appeal in progress, so you always know exactly where your revenue stands. No guessing, no waiting on a monthly summary to find out a claim was denied three weeks ago. You stay fully informed while we do the heavy lifting.

Get started without disrupting your practice

Switching your billing does not have to mean stopping what you are doing or training a whole new team from scratch. Most practices worry that moving to an outside billing partner will slow down their claims during the switch — and that fear alone keeps a lot of practices stuck with a billing process that is already losing them money. Our onboarding is built to fit around your practice. We pull your existing patient and claim data, set up your billing workflow, and start submitting clean out-of-network claims within days, not months.

Your patient data stays protected

Billing touches sensitive patient information every single day, and that information has to stay locked down at every step, from intake to claim submission to payment posting. A billing partner cutting corners on data security is a risk your practice cannot afford to take. Every part of our billing process follows HIPAA requirements, with secure handling of patient records, claims, and payment data at every stage. Your patients' information stays protected, and your practice stays covered

Simple pricing, no hidden fees

A lot of billing services bury their real cost in fine print — extra charges for claim volume, add-on fees for appeals, or a contract that locks your practice in for years. That is not how we work. Our pricing is straightforward and tied to the work we actually do for your practice, with no surprise charges buried in the fine print. You know exactly what you are paying for, and every dollar of it goes toward getting your out-of-network claims paid — faster and more completely than before.

A dedicated team

When a claim gets stuck, you should not have to explain your practice's whole history to a new person every time you call for an update. Practices working with call-center style billing services lose time repeating the same details over and over, while claims sit unresolved in the background. With MZ Medical Billing, your practice gets a dedicated billing team that already knows your specialty, your patient volume, and your claim history. When you need an update, you are talking to someone who already knows the account.

Your out-of-network claims are worth more than you are collecting

Every delayed payment and every denied claim is revenue that belongs to your practice. MZ Medical Billing takes over the entire out-of-network billing process, so nothing gets missed and nothing gets left unpaid.

FAQS

Frequently asked questions

How fast can out-of-network claims get paid with your service?

Turnaround depends on the insurance company, but clean claims with full documentation move far faster than claims sent without it. Our follow-up process also catches slow claims before they get lost in the system.

Do you handle appeals for denied out-of-network claims?

Yes. Every denied or underpaid claim is reviewed and appealed with stronger documentation until it is resolved.

Will my billing stay compliant with the No Surprises Act?

Yes. Every applicable claim is built around current No Surprises Act and AB 72 requirements.

Do you create superbills for us or do we still need to?

We generate the superbills for you, straight from your practice records, for every out-of-network visit.

Can you check a patient's out-of-network coverage before their appointment?

Yes. Coverage checks happen before treatment, so both you and your patient know what to expect.

How long does onboarding take?

Most practices are fully set up and submitting clean out-of-network claims within days, without any disruption to their front desk.

What is balance billing, and does your service handle it?

Balance billing is the gap between your full charge and what insurance agrees to pay. We bill this correctly for every claim, and flag cases where surprise billing laws apply so your practice stays compliant.
