One partner for the work behind the care
Core MB is a Brooklyn-based healthcare services company. We handle credentialing, medical billing and revenue cycle management, website development, digital marketing and virtual assistant support — so providers can spend their time on patients.
Putting the core of your billing at the center of ours
We started with a straightforward observation: most practices lose money not because they are underpaid, but because nobody has the time to chase what is owed. Claims stall. Credentialing applications sit in a payer queue for months. Denials pile up.
Core MB exists to take that work off your desk. Our credentialing team follows up with payers every third day, and every client can watch their applications move in the portal. Our billing team owns each claim through to payment. And we report on all of it honestly, so you always know where you stand.
Over time clients asked for more — a website that actually brings in referrals, a social presence somebody keeps up with, an assistant to handle scheduling and EMR updates. So we built those services too, staffed by the same people and held to the same standard.
Our mission is to provide exceptional medical billing services that enhance your financial health.
Our vision: to set the standard in medical billing through quality and technology.
Why practices choose Core MB
Integrity and ethics
Clean, defensible billing. We will tell you when something cannot be coded the way you hoped.
Commitment
Payers are chased every third day. Claims are owned to resolution, not filed and forgotten.
Excellence in the detail
Measured against outcomes — approvals confirmed, claims paid, AR recovered — not activity reports.
Fiscal soundness
A stable partner. Your revenue cycle should not depend on a vendor's cash flow.
Cultural competence
Teams that communicate well with your patients and your front office, in plain language.
What we hold ourselves to
Integrity
We run the business to the highest ethical standard — honest reporting, transparent terms, and accountability when something goes wrong.
Excellence
We keep sharpening our skills, processes and technology, because clean claims and fast approvals are a floor to defend, not a trophy to display.
Innovation
Payer rules, coding sets and platforms change constantly. We stay at the front of those changes so your practice does not absorb the disruption.
Customer focus
Your success is the only measure that counts. We build the solution around how your practice actually works, not around a standard package.

What does a medical billing company actually do for my practice?
We take over the logistical work of getting you paid. That means coding the encounter, filing the claim, chasing the payer, posting the payment and following up on anything that stalls. Practices that outsource billing typically see lower overhead, steadier cash flow, fewer denials, and a front office that can spend its time on patients rather than invoices.
Which billing services are included?
Provider enrollment, insurance verification, charge entry, claim submission, payment posting, accounts receivable management, denial management, appeal management, patient billing, reimbursement tracking and collections. Most clients take the full cycle, but you can start with a single piece such as AR recovery or credentialing.
How do you handle denials and underpayments?
Submitting a clean claim is only the first step. Once a claim is filed we own it — we speak to payers directly, track status daily, and act as soon as something stalls. Underpaid and denied claims go into a persistent follow-up cycle with appeals filed where they are warranted, so your practice recovers what it is owed rather than writing it off.
Can I see how my billing is performing?
Yes. You get reporting on daily charges and payments, the key performance markers for your revenue cycle, and a plain-language read on what is working and what needs attention. Nothing is hidden behind a portal you have to interpret alone.
Do you work with Medicare and Medicaid claims?
We do. Every state sets its own filing rules and reimbursement requirements for Medicaid, and Medicare has its own moving parts. We stay current on both, apply the right forms and codes the first time, monitor each claim through adjudication, and handle appeals when they are needed.
How do the new services — websites, marketing and staffing — fit with billing?
They come from the same place: practices kept asking us to solve problems next door to billing. A site that does not convert, a Google listing nobody updates, an open biller seat that takes three months to fill. You can engage any of these on their own — you do not need to be a billing client to hire us for a website, a marketing program or staff.
