Vexta RCM: A Billing Partner Built for Every Type of Practice

Introducing Vexta RCM: A Billing Partner Built for Every Type of Practice

Every healthcare organization’s financial stability rests on one thing: a billing process that actually works. Claims that go out clean, denials that get caught before they happen, and receivables that don’t sit aging for months. That’s the foundation Vexta RCM was built on.

We’re a revenue cycle management partner offering end-to-end billing solutions — not built around one facility type, but built to flex across the full range of practices we work with: solo and group physician practices, ambulatory surgery centers, specialty clinics, FQHCs, urgent care centers, and more.

Specialties We Support

Every specialty has its own coding rules, payer quirks, and denial patterns. Our team is built around that reality, with dedicated experience across:

  • Mental & behavioral health
  • Cardiology
  • Orthopedics
  • Neurosurgery
  • General & ambulatory surgery
  • Oncology
  • Dermatology
  • Pathology
  • Urgent care
  • Podiatry
  • Wound care & rehab
  • DME (durable medical equipment)
  • FQHCs and community health clinics

Whichever specialty your practice falls under, you get a team that already understands its billing nuances — not a generalist learning on your account.

What We Handle

Revenue Cycle Management Full oversight of your financial pipeline, from the moment a claim is generated to the moment it’s paid — so nothing falls through the cracks, regardless of your facility type.

Medical Billing Services Full-service claim submission, charge entry, and payment posting, powered by technology that keeps your workflow simple and your collections consistent.

A/R Recovery & Denial Management Targeted strategies to chase down aging receivables and resolve denied claims before they turn into write-offs, with a clear plan for every claim sitting in your A/R.

Front Office Services Scheduling, insurance eligibility verification, prior authorization, and patient registration — proactive front-end support that prevents denials before they happen.

EHR/EMR & Practice Management Integration We work within the systems your team already knows, streamlining clinical and administrative workflows rather than forcing a disruptive software switch.

Patient Engagement Solutions Tools that make the payment experience clearer for patients — which means fewer billing disputes and better collection rates for you.

Why Outsource Your Revenue Cycle

Running an in-house billing department is expensive: recruiting, training, software licenses, and ongoing management all add up before a single claim is submitted. Outsourcing your revenue cycle management to Vexta RCM removes that overhead entirely. Our billing and coding team manages your revenue cycle end-to-end — from initial claim submission to final payment — so your staff can stay focused on patient care instead of chasing reimbursements.

The Vexta Advantage

Practices that partner with us see meaningful revenue growth as a direct result of reduced denials, faster A/R recovery, and cleaner claim submissions — regardless of specialty or facility size. Every practice is different, which is exactly why we start every partnership by reviewing your specific numbers, not a generic industry average.

The Top Health Insurance Payers in the US

The Top Health Insurance Payers in the US — What Providers Need to Know

By the Vexta RCM Team

When patients search “top health insurance companies,” they’re usually shopping for a plan. When providers ask the same question, the stakes are different: these are the payers your practice bills every day, and their size, rules, and reimbursement behavior shape your revenue cycle whether you’re credentialed with them or not.

Here’s a provider-focused look at the largest payers in the US market — and what their scale actually means for your practice.

The Biggest Payers by Market Share

Based on the most recent National Association of Insurance Commissioners (NAIC) market share data for accident and health premiums, ten payer groups account for roughly 60% of the entire US health insurance market. In order of size:

  1. UnitedHealth Group (UnitedHealthcare) — the largest payer by a wide margin, controlling roughly 16% of the national market
  2. CVS Health (Aetna) — climbed to the #2 spot on the back of its pharmacy-and-insurance combination
  3. Centene Corporation — the largest Medicaid managed care organization in the country
  4. Humana — dominant in Medicare Advantage, particularly for senior-heavy practices
  5. Elevance Health — formerly Anthem, with deep Blue Cross Blue Shield roots
  6. Kaiser Permanente — an integrated care model, but only available in a handful of states
  7. HCSC (Health Care Service Corporation) — a regional powerhouse in its core states
  8. Cigna — strong in employer-sponsored coverage
  9. Molina Healthcare — Medicaid- and marketplace-focused
  10. GuideWell (Florida Blue) — a reminder that “largest” is sometimes regional, not national

Why Market Share Matters to Your Billing Team — Not Just Patients

A consumer researching these names cares about premiums and provider directories. Your billing team should care about something different:

Credentialing priority. If your practice isn’t yet paneled with a payer that covers 15–16% of the national market, that’s a meaningful gap in your patient acquisition pipeline. Credentialing timelines can run 60–120 days, so prioritizing the highest-volume payers in your region first has an outsized impact on new-patient revenue.

Claims volume and denial patterns differ by payer. Larger payers process enormous claim volumes through highly automated systems — which means their denial rules are also automated and unforgiving of small documentation gaps. Smaller regional payers sometimes offer more flexibility, but slower turnaround.

Medicaid managed care requires different workflows. Payers like Centene and Molina operate largely through Medicaid managed care, which comes with its own prior authorization rules, timely filing limits, and state-specific quirks. A billing process built around commercial payer norms will generate avoidable denials here.

Medicare Advantage is growing fast. With Humana and UnitedHealthcare together representing nearly half of all Medicare Advantage enrollment, practices that see a meaningful senior population should expect MA-specific prior authorization and referral requirements to keep growing in complexity.

A Practical Checklist for Practices

  • Map which of the top payers you’re currently credentialed with — and which represent the biggest gap in your region
  • Review denial patterns by payer, not just in aggregate — a payer-specific trend often points to a payer-specific fix
  • Confirm your front office is verifying eligibility payer-by-payer, since rules (referrals, prior auth, filing windows) vary meaningfully even among the largest names on this list
  • Revisit your Medicaid and Medicare Advantage workflows separately from commercial billing — they are not interchangeable

How Vexta RCM Helps

Understanding the payer landscape is only useful if your billing and credentialing processes are built around it. Our Revenue Cycle Management and A/R Recovery teams track denial and reimbursement patterns by payer, so your practice isn’t guessing which payer relationships need attention first.

Top 10 Medical Billing Denial Codes

Top 10 Medical Billing Denial Codes Every Practice Should Know

By the Vexta RCM Team

Denials are the single biggest drag on a practice’s cash flow — and most of them are preventable once you know what to look for. Below, we break down the ten denial codes we see most often across specialties, what they mean, and the fastest way to fix and prevent each one.

Why Denials Deserve Your Attention

Every denied claim is money sitting in limbo. Left unmanaged, denials pile up, age past the point of easy recovery, and quietly erode revenue that your practice has already earned. The good news: the majority of denials fall into a handful of predictable categories. Once your team recognizes the pattern, fixing it — and preventing it from recurring — becomes routine instead of a fire drill.

The Codes That Cost Practices the Most

Eligibility & Coverage Issues

PR-276 — Not Eligible on Date of Service The patient’s coverage had lapsed or changed by the time the service was rendered. This is almost always a front-desk catch: verify eligibility at every visit, not just at intake, since coverage can change month to month.

CO-119 — Benefit Maximum Reached The payer has already paid out the patient’s allowed benefit for that service type. Confirm remaining benefits before the appointment, and give patients a heads-up if they’ll owe out-of-pocket.

Denial Code 97 — Service Not Covered The plan simply doesn’t include this service. Confirming coverage in advance — and having an alternative-treatment conversation with the patient early — avoids the surprise entirely.

Coding & Documentation Mismatches

CO-11 — Diagnosis Inconsistent With Procedure The submitted diagnosis doesn’t support the billed procedure in the payer’s eyes. Usually traced back to a mismatch between provider notes and the codes selected. A second set of eyes on ICD-10/CPT pairing before submission catches most of these.

CO-167 — Diagnosis Not Covered The diagnosis code itself isn’t payable for the billed service under that plan’s policy. Cross-check payer-specific coverage policies rather than assuming a code that worked for one payer works for all.

CO-16 — Missing or Invalid Information A catch-all for incomplete claims — missing modifiers, an invalid NPI, a mismatched date of birth. A claim scrubber that flags incomplete fields before submission eliminates most CO-16 denials before they ever reach the payer.

Timing & Duplication

CO-29 — Timely Filing Limit Exceeded The claim arrived after the payer’s filing deadline — and once it’s late, it’s usually late for good. Track each payer’s filing window (they vary) and build submission deadlines into your workflow rather than your memory.

Denial Code 18 — Duplicate Claim The payer believes this claim was already submitted. Check claim status before resubmitting anything, and if it genuinely wasn’t a duplicate, appeal with the original submission record attached.

Patient Responsibility & Coordination

PR-3 — Patient Responsibility This isn’t technically a “denial” in the traditional sense — it’s the payer correctly routing the deductible, copay, or coinsurance to the patient. Clear, upfront communication about estimated out-of-pocket costs reduces billing disputes later.

CO-B11 — Coordination of Benefits Required The payer needs clarity on which insurance is primary. A quick COB update from the patient, confirmed with the insurer, usually resolves this in one call.

Turning Denial Codes Into a Prevention System

Recognizing a code after the fact is only half the job. The practices that keep denial rates low build these habits into their workflow:

  • Verify eligibility every visit — coverage changes more often than people expect.
  • Scrub claims before submission — catch missing fields and mismatched codes automatically.
  • Track denials by category, not just by claim — recurring CO-29s or CO-119s point to a process gap, not bad luck.
  • Communicate costs to patients early — it prevents PR-3 disputes down the line.
  • Appeal promptly and with documentation — many “hard” denials are actually recoverable if you act fast.
