MB2 Dental: Fillings, Referral Payments and Provider Numbers

In MB2 Dental’s 2017 Medicaid settlement, the management company, participating practices, owners and marketing chief agreed to pay $8.45 million to resolve allegations of fillings never performed, kickbacks and incorrect provider numbers. The whistleblower’s complaint described how patient recruitment and treatment pressure met in the billing office: referral checks tied to completed visits, instructions to maximize the first appointment, and payroll codes connecting recruiters to particular clinics.

The whistleblower alleged that the management company billed Medicaid more than $100,000,000 for the practices in 2011 alone. We see the scale in that contrast: a single year’s alleged billings dwarfed the settlement.

What MB2’s Medicaid Settlement Resolved

The government alleged that MB2 and participating practices billed the Texas Medicaid Fee for Service Program for single-surface fillings in children that they never provided, from January 1, 2009 through December 31, 2014. The settlement also resolved allegations that MB2 paid patients, families and marketers for referrals, and that MB2 and the practices used incorrect Medicaid provider numbers to misrepresent which dentists performed procedures.

A former MB2 employee brought part of the allegations through a False Claims Act qui tam case, which the government joined. This was a Medicaid dental fraud case about provider claims. Fee-for-service dentistry pays by procedure. In the government’s allegations, the program paid for fillings the children never received.

The Management Company Behind the Practice Names

The 2017 settlement announcement described MB2 Dental Solutions as a dental management firm based in Carrollton, Texas, providing management services to dental offices. The whistleblower’s amended complaint described Dental Professionals of Texas, called DPT in the complaint, as the business that became MB2. It alleged that DPT handled human resources, billing and government regulatory contact for the practices.

The whistleblower’s position gave her a view across those functions. Her complaint said she began as an office manager at Wow Dental, became a regional manager with access to patient records, billings, marketing and budgets, and later worked in the referral business. A clinic name on a claim could conceal a management decision made elsewhere. Her account connected the dental offices to the people controlling recruitment and billing.

Single-Surface Fillings and First-Visit Billing Pressure

The government’s filling allegation was specific: Medicaid claims for single-surface fillings that children did not receive. The whistleblower’s complaint described a broader pressure to increase billings, including treatment she alleged was unnecessary and work she said could not fit into the available day.

According to the complaint, dentists received a percentage of the billings they generated. Management shared practices’ patient counts and daily billings with other offices and pressed them to increase both the number of patients and the services billed per patient.

The complaint described the first appointment as a revenue opportunity that staff were told to exhaust:

The whistleblower alleged that staff aimed to bill $2,000 for each patient whether the work was needed or not, using what she described as Medicaid’s payment ceiling as the target. She also described work in all four quadrants of a child’s mouth at the first visit.

Drawing on her dental-office experience, she said dentists should treat only one or two quadrants per visit because of patient stress and the time needed to do the work, especially with young children. We see a telling priority in that alleged instruction: make the most of the child’s bill before the family can go elsewhere. In the whistleblower’s account, fear of losing revenue was choosing the child’s treatment.

For one day at Wow Dental, September 16, 2011, the complaint alleged that three dentists billed for 90 Medicaid patients and more than $63,000 in services. The whistleblower argued that the claimed work, including multiple fillings and crowns, could not physically have been performed in the available time. That allegation connects a billing total to the people and hours available to do the work.

The government’s 2018 settlement with Benevis and Kool Smiles likewise addressed alleged production pressure. The Justice Department alleged that clinics rewarded procedure revenue with cash bonuses, disciplined dentists deemed unproductive and ignored dentists’ complaints about excessive treatment.

Referral Payments That Followed the Patient Visit

The MB2 settlement’s Medicaid provider kickback allegations covered payments to beneficiaries and families as well as marketers and marketing entities. The complaint explained the alleged connection between the payment and the visit: a recruiter earned the payment when the patient registered and received services.

The whistleblower alleged that recruiters received additional cash or electronics after bringing more than 100 Medicaid patients into the offices in a month. Parents allegedly received payments to bring their children, and relatives received payments for referring other family members. The complaint described practice-level promotion budgets used for items such as gift cards and manicure or pedicure certificates.

The whistleblower alleged that local television reports on dental kickbacks prompted the MB2 name change and a new referral arrangement. The alleged referral business later ran through KHB Community Outreach Associates, which the complaint said operated from the same office as the management company and had it as its only customer. According to the whistleblower, workers wore community outreach shirts and received hourly pay through KHB, while continuing the referral scheme.

The complaint pointed to a particularly useful detail in the payroll register: department codes identified the dental practice associated with each worker. The whistleblower alleged that the codes connected payments to referrals for specific offices even though another company issued the payroll. A different name on the paycheck did not, in her account, sever the connection to the clinic.

A separate Texas dental-network lawsuit announced in March 2026 shows why those connections matter. The Attorney General’s Healthcare Program Enforcement Division alleged that dentists paid marketers per patient under the guise of surveys and marketing, while families received cash, gift cards or electronic payments. That announcement identified marketing agreements, invoices, patient spreadsheets and annotated payments as evidence of the alleged scheme. The same question runs through both accounts: which patient visit was the marketing payment buying?

Provider Numbers and Who Performed the Work

The government alleged that MB2 and the practices used erroneous Medicaid provider numbers to misrepresent which dentists performed pediatric procedures. That is a separate provider-claim issue from whether a filling occurred.

The 2012 Journal of Information Systems Applied Research paper Applying Business Intelligence Concepts to Medicaid Claim Fraud Detection describes a review approach that considers money flows, medical logic, treatment frequency, the place and timing of services, and how providers identify themselves to the insurer. Applied to the MB2 allegation, the useful comparison reaches from the dentist identified on the claim to the treatment records and staffing for that visit. An employee familiar with both can explain a discrepancy that a claim total leaves hidden.

The Settlement Payments, Whistleblower Reward and Independent Review

The settlement announcement separately described obligations for five dentist owners or part owners, each agreeing to pay $250,000 to resolve the claims against them individually. MB2’s marketing head agreed to pay $100,000.

The Texas Attorney General’s announcement said the state would receive approximately $4.2 million of the agreed settlement. The federal announcement said the former employee would receive a whistleblower reward of $1.5 million from the United States and Texas. A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers.

MB2 and the dentist owners also entered a five-year corporate integrity agreement with HHS-OIG. The government said an independent review organization would assess annually whether claims reimbursed by federal health care programs were correctly coded, medically necessary and appropriately documented.

What Evidence Is Needed to Prove Fraud?

For allegations like these, the useful evidence connects treatment records, submitted claims, referral payments and the management decisions behind them. Our whistleblower experts work with you to establish how those pieces fit: who did the work, what was billed and who gave the orders.

The 1999 Harvard University report Controlling Fraud and Abuse in Medicaid: Innovations and Obstacles made the case for looking across provider numbers:

The report called for detection methods that could find schemes spread across multiple providers and patients, informed by knowledge of how the business works. The MB2 complaint gives that point a concrete setting: shared billing, promotion budgets and a referral payroll linked to individual offices. We want to understand the decisions behind those records with the person who saw them being made.
