If you search for medical billing services near me in New Jersey, choose on specialty fit and fee model, not on distance, because most billing work happens remotely. InfiniteRCM suits general and multi-specialty practices that want billing, AR recovery and credentialing from one team. AMBSI suits practices with no-fault PIP and workers’ compensation claims. Capital Medical Billing Solutions suits surgical practices with out-of-network volume, and Amromed suits behavioral health and therapy practices. Konnext Solutions suits new practices that need payer enrollment first. Advanced Medical Billing and Collections suits practices that want dedicated remote billing staff, and Millennium Medical Billing suits established specialty groups.
Most New Jersey practices that go looking for a billing company have the same problem. Denials pile up, AR days stretch, and your front-desk staff spend afternoons on hold with payers. The payer mix makes it harder: Medicare, NJ FamilyCare, commercial carriers, auto no-fault PIP and workers’ compensation each follow different rules. Search results for this topic mix agencies, directories and job boards, so it is hard to see who actually fits your practice.
This article compares seven New Jersey options side by side, then explains the fee models and what billing typically costs. InfiniteRCM is our company, based in Chester, NJ, so we list it first and describe it from what we do. We describe the other six from what they publicly state about their services, so confirm the details on a call before you sign anything.
1. InfiniteRCM
InfiniteRCM is a revenue cycle management company in Chester, NJ that runs your billing remotely, from eligibility checks to denial appeals.
Services and focus
The core service is full revenue cycle management: patient eligibility verification, clean claim submission, payment posting, denial management and financial performance reporting. Around that, InfiniteRCM offers AR recovery for unpaid claims, underpayments and appeals, credentialing and payer enrollment (including CAQH profile management and NPI registration support), and medical virtual assistants for scheduling, insurance verification and prior authorizations.
- Claims go out electronically through secure clearinghouses, usually within 24 to 48 hours after charge entry.
- The team works inside your existing systems remotely, so you buy no software.
- The company reports a 99% clean claim rate, 40% faster collections and 60% fewer denials.
- It reports 500+ providers served and over $50M in revenue recovered for clients.
Best fit and what to check
This is the right pick if you run a solo practice, a clinic or a multi-provider group and want one team for billing, AR cleanup and credentialing. It serves family medicine, cardiology, orthopedics, urgent care, laboratories and other specialty practices.
If you want one team to own the whole revenue cycle, a single vendor beats stitching together three.
Before you sign, ask for the fee structure in writing. InfiniteRCM states transparent pricing with no hidden fees. Onboarding typically takes a few days to a few weeks depending on setup complexity, and you get a dedicated account manager. Support answers within 24 business hours. Monthly contracts end with 30 days of written notice, and late payments can accrue 1.5% interest per month. Read those terms for any vendor you consider.
2. AMBSI Inc.
AMBSI (American Medical Billing Solutions) is a Sayreville, NJ company that stands out for claim types many general billers avoid, namely no-fault PIP, workers’ compensation and out-of-network claims.
Services and focus
AMBSI reviews claims before submission, analyzes the root causes of denials and recovers aged accounts receivable. Its service list also includes prior authorization support, ASC billing, pain management billing and anesthesia billing for New Jersey facilities.
- Location: Sayreville, serving Middlesex County and the wider state
- Specialty angle: no-fault PIP and workers’ compensation
- Also covers: ASC, pain management and anesthesia
Best fit and what to check
Choose AMBSI if auto-accident and workers’ comp claims make up a large share of your revenue. Those claims run on their own fee schedules, forms and filing deadlines, and a general biller can lose money on them.
Match the biller to your hardest claim type, because that is where weak billing costs you most.
Ask how they track filing deadlines and handle disputed PIP claims. Also ask for a sample monthly report. If most of your patients carry standard commercial insurance, a general RCM firm may be a better fit.
3. Capital Medical Billing Solutions
Capital Medical Billing Solutions, based in Long Branch, NJ, focuses on surgical and out-of-network billing, where underpayment is the main risk.
Services and focus
The firm works with surgical specialists and hospital-affiliated practices on complex procedures. Its work covers coding analysis, claims management and payer negotiations. It also lists experience with the federal No Surprises Act and state arbitration filings, plus credentialing and EDI enrollment.
- Location: Long Branch, NJ
- Specialty angle: surgical and out-of-network claims
- Also covers: credentialing and EDI enrollment
Best fit and what to check
This is a fit for surgeons and surgical groups that treat out-of-network patients and want help recovering payments that payers underpay or deny. New Jersey’s Out-of-Network Consumer Protection, Transparency, Cost Containment and Accountability Act shapes how those disputes work, so state-level experience matters.
For out-of-network work, ask who files the disputes and what share of the recovery they keep.
Ask how fees work on recovered amounts and how they report arbitration outcomes. A primary care practice with mostly in-network visits will pay for expertise it does not use.
4. Amromed LLC
Amromed is a Jersey City company that bills for therapy and behavioral health practices, a niche where payer rules differ sharply from general medicine.
Services and focus
Amromed handles ABA therapy, mental health and pediatric therapy billing across New Jersey. Its services cover claim submission, payment posting, denial management and AR follow-up, along with provider credentialing and re-credentialing. It also supports single case agreements and works inside platforms such as TherapyNotes.
- Location: Jersey City, NJ
- Specialty angle: ABA, mental health, pediatric therapy
- Also covers: single case agreements and re-credentialing
Best fit and what to check
Pick Amromed if you run a behavioral health or therapy practice. Authorization limits and payer-specific unit rules cause most denials in this field, and a biller who knows them prevents rework.
In behavioral health, authorization and unit rules cause the denials, so specialty experience is the first filter.
Confirm they can work in your current practice platform and ask how they track authorizations as they expire. If your practice mixes therapy with general medical services, ask how they split the work.
5. Advanced Medical Billing and Collections
Advanced Medical Billing and Collections, known as AMBNJ, is an East Brunswick, NJ company founded in 2011 that pairs billing with dedicated remote staffing.
Services and focus
AMBNJ offers claim submission, clinical coding, credentialing, denial management and AR management with certified ICD-10 and CPT coders. Its less common option is remote staffing: you can hire vetted coders and billers through the company instead of recruiting in-house.
- Location: East Brunswick, NJ, serving New Jersey and beyond
- Specialty angle: billing plus remote RCM staffing
- Also covers: eligibility verification and credentialing
Best fit and what to check
This works for practices that want dedicated people on their account without the cost of hiring and training. It also suits groups that already have a billing process and need extra capacity.
Staffing models give you control, but you still need a manager on your side to direct the work.
Clarify who supervises the staff day to day, how performance is reported, and what happens when a team member leaves. Compare that model against a fully managed service, where the vendor owns the outcome rather than the hours.
6. Konnext Solutions
Konnext Solutions is a Jersey City company built around credentialing and payer contracting, with billing added on top.
Services and focus
Credentialing, payer contracting and rate negotiation sit at the center of its service list. After enrollment, it adds coding, denial management and AR follow-up. It uses an in-house claim scrubbing tool called SmartClaim and lists internal medicine, pediatrics and mental health among its specialties.
- Location: Jersey City, NJ
- Specialty angle: credentialing and payer enrollment first
- Also covers: coding, denials and AR follow-up
Best fit and what to check
Konnext fits a new or growing practice that needs panel enrollment before billing volume exists. You cannot bill a payer until the provider is enrolled, so a delay here delays all revenue.
If your providers are not yet enrolled, start with credentialing, because no claim gets paid before that.
Ask for realistic enrollment timelines, since payer approvals often take weeks to months. Ask how they charge for enrollment versus ongoing billing, and how the handoff works once you start seeing patients.
7. Millennium Medical Billing
Millennium Medical Billing is a New Jersey-based firm founded in 1997, which gives it one of the longest track records on this list.
Services and focus
The company bills for 21 specialties, including pain management, neurosurgery, ENT, gastroenterology and OB-GYN. Besides billing and coding, it offers credentialing and a free consultation so you can see how it would work with your practice.
- Location: New Jersey
- Specialty angle: established multi-specialty billing
- Also covers: coding and credentialing
Best fit and what to check
Millennium suits an established specialty practice or group that values longevity and wants a vendor with nearly three decades behind it. A long history helps when payer rules change and you need someone who has seen it before.
A long track record only helps if your specialty is on the list, so confirm that first.
Ask for references from practices in your specialty and check how its reporting compares with what you track today. Also confirm the contract term and the exit process, which matter more than the sales pitch.
Choosing a New Jersey billing company and what it costs
Choose on specialty fit, fee model and reporting, and expect to pay either a percentage of collections or a fixed amount per claim, month or hour. Distance matters far less than whether the biller knows your payers.
Fee models and a worked cost example
Billing companies price in four common ways. Percentages vary by specialty, volume and services included, and a range of roughly 4% to 10% of collections is commonly quoted.
| Fee model | How it works | Works best when |
|---|---|---|
| Percentage of collections | You pay a share of what is collected | Collections are steady and you want aligned incentives |
| Per claim | A flat amount for each claim submitted | Claim volume is high and claims are low in value |
| Flat monthly or per provider | A fixed fee regardless of volume | You want a predictable budget |
| Hourly or full-time equivalent | You pay for dedicated remote staff | You need people for tasks beyond billing |
Take a practice that collects $60,000 a month. At 4% the fee is $2,400. At 6% it is $3,600, which is $43,200 a year. At 8% it is $4,800. A per-claim quote works differently: 800 claims at a hypothetical $3 each is also $2,400. Compare the total each model produces for your volume, then ask what is excluded, such as credentialing or patient statements.
Questions to ask before you sign
Use the same list with every vendor so the answers are comparable.
- Do you bill my specialty and my payer mix, including NJ FamilyCare and any no-fault or workers’ comp claims?
- How do you measure clean claim rate and denial rate, and how often will I see reports?
- Will you work inside my EHR and practice management system?
- Will you sign a HIPAA business associate agreement?
- Who is my day-to-day contact, and how fast do they respond?
- What are the cancellation terms, and do I keep access to my data?
Does a local company matter?
A local biller helps with payer knowledge, not with proximity. New Jersey practices deal with Medicare, NJ FamilyCare, commercial carriers such as Horizon Blue Cross Blue Shield of New Jersey, auto no-fault PIP and state out-of-network rules. A biller who handles these every day will make fewer mistakes.
Nearly all billing work is done remotely and in the same time zone, so you rarely need anyone in your office. Treat "near me" as a filter for New Jersey payer experience, then judge each company on the checklist above.
Picking the right billing partner
The best medical billing company for you is the one whose specialty and fee model match your practice. Use the seven options as a shortlist: no-fault and workers’ comp, surgical out-of-network work, behavioral health, remote staffing, credentialing first, and long-established multi-specialty billing each have a clear match. For a general or multi-specialty practice that wants billing, AR recovery and credentialing together, InfiniteRCM is built for that.
Whichever vendors you shortlist, ask the same questions, compare the total cost at your own collection volume, and read the cancellation terms before you commit. If you want to see how InfiniteRCM would handle your claims, contact the InfiniteRCM team and ask for a walkthrough of your current denials and AR.
