Background: A Practice That Thought It Had Its Insurance Figured Out
Dr. Marlowe had built what she considered a well-run, financially stable general dentistry practice in a mid-sized suburban market. Over 18 years, she’d grown the practice to two associate dentists, $2.4 million in annual production, and a full-time office manager with more than a decade of dental billing experience.
Her insurance mix was something she reviewed annually. She’d made deliberate decisions about which PPO networks to join, had exited two networks that were underperforming, and believed she had a clear picture of her practice’s financial profile. Collections were consistently in the 95-96 percent range. Overhead was well-managed. By most measures, the practice was performing well.
What Dr. Marlowe didn’t know — and what her experienced billing team hadn’t detected — was that her practice was unknowingly participating in four separate rented network arrangements that were collectively costing the practice more than $94,000 per year in preventable write-offs.
How the Problem Was Discovered
The discovery came through an indirect path. Dr. Marlowe was exploring adding a third associate and wanted to model the revenue impact accurately. She reached out to PPO Negotiation Solutions to help benchmark her current fee schedules against market rates before expanding.
During the initial consultation, a preliminary review of her EOB data raised flags. The analyst noticed payer names appearing regularly in her claims data that weren’t reflected in her practice’s direct participation agreement inventory. More specifically, the write-off amounts from those payers aligned precisely with her contracted rates from two of her primary carriers — a pattern consistent with rented network access.
Dr. Marlowe was skeptical at first. ‘We’ve been doing this for 18 years,’ she recalled. ‘My office manager knows billing inside and out. I found it hard to believe something this significant could be happening without us knowing.’
A full PPO network analysis was initiated.
The Analysis: What the Data Revealed
The formal PPO network analysis involved a systematic review of 14 months of claims data, cross-referenced against Dr. Marlowe’s complete contract inventory and EOB records. The process took approximately three weeks and produced a detailed findings report.
The analysis identified the following:
Rented Network #1: A Regional TPA Accessing Her Cigna Fee Schedule
A regional third-party administrator was processing dental claims for several self-funded employer plans in her market. The TPA had a network access agreement with Cigna that allowed them to use contracted provider rates. Dr. Marlowe had never heard of this TPA and had never agreed to participate in their network.
The financial impact: $28,400 in annual write-offs from claims processed at Cigna contracted rates for patients the practice didn’t know were part of a rented network arrangement.
Rented Network #2: A Small Commercial Carrier via Network Aggregator
A small commercial dental insurer operating in two adjacent states had purchased network access through a national dental benefits aggregator, which in turn had a reciprocity agreement with one of Dr. Marlowe’s primary carriers. Her fee schedule was part of the access package.
The financial impact: $19,200 in annual write-offs. Because this carrier’s patient volume was low, individual claims were small — which is exactly why they’d gone unnoticed.
Rented Network #3: A Workers’ Compensation Payor
Workers’ compensation dental claims were being processed at Dr. Marlowe’s Delta Dental PPO contracted rates. Workers’ comp dental reimbursement varies significantly by state, and the practice’s actual contracted rates were substantially lower than the workers’ comp market rate she was entitled to receive as an out-of-network provider.
The financial impact: $31,600 in annual write-offs — the largest single source of rented network losses. This arrangement was particularly significant because workers’ comp fee schedules in her state actually favored providers who were not contracted under standard PPO rates.
Rented Network #4: A Medicaid Managed Care Organization
A Medicaid managed care plan had a network access agreement that allowed them to use her primary carrier’s fee schedule for dental claims. The practice had never applied to participate in Medicaid managed care and was not aware it was effectively functioning as a participating provider for this plan.
The financial impact: $14,800 in annual write-offs.
Total identified rented network exposure: $94,000 per year — representing approximately 3.9% of total annual production, entirely undetected by the practice’s internal billing process.
The Response Strategy
PPO Negotiation Solutions developed a multi-step response strategy tailored to the specific circumstances of each rented network arrangement. The approach varied by arrangement because the options available — and the risk of disrupting legitimate patient relationships — differed for each.
Step 1: Formal Written Notice to Primary Carriers
The first action for rented networks #1 and #2 was to send formal written notice to Dr. Marlowe’s primary carriers requesting full disclosure of all entities with licensed or leased access to her fee schedule. Both carriers were required to respond, and both did — confirming the arrangements that had been identified in the analysis.
Step 2: Opt-Out Request for Specific Network-Sharing Provisions
After reviewing the participation agreement language for each primary carrier, the team identified specific provisions that governed fee schedule sharing and network access. For two of the four arrangements, the practice had the contractual right to opt out of specific affiliated network access — a provision that existed but was not commonly communicated to providers.
Opt-out requests were submitted for rented networks #1 and #2. Both carriers complied within 45 days.
Step 3: Workers’ Comp Re-categorization
For the workers’ compensation arrangement, the strategy involved formally notifying the workers’ comp payor that the practice was not a contracted network provider for workers’ comp claims and establishing the appropriate billing protocol going forward. This required careful coordination to avoid disrupting care for existing workers’ comp patients while transitioning to appropriate out-of-network billing.
The outcome: workers’ comp claims were subsequently billed at the practice’s UCR rate with appropriate state workers’ comp fee schedule guidelines — resulting in materially higher reimbursement per claim.
Step 4: Medicaid Managed Care Credentialing Decision
The Medicaid managed care situation was handled differently. After reviewing the patient demographics, Dr. Marlowe decided to formally credential with the managed care plan rather than terminate the arrangement — but at properly negotiated rates rather than through rented network access. This actually resulted in a modest improvement in Medicaid reimbursement rates and gave the practice direct contract control over those claims going forward.
The Results: 14 Months Post-Engagement
Fourteen months after the PPO network analysis was completed and the response strategy was implemented, the practice was able to quantify the financial outcomes:
- Rented network #1 (TPA/Cigna): Fully resolved. Estimated annual recovery: $28,400.
- Rented network #2 (small commercial carrier): Fully resolved. Estimated annual recovery: $19,200.
- Rented network #3 (workers’ comp): Partially resolved. The practice retained workers’ comp patients but billed appropriately. Net improvement in reimbursement per claim: approximately 34%. Estimated annual recovery: $21,500.
- Rented network #4 (Medicaid managed care): Converted to direct credentialing. Reimbursement improved by approximately 12% compared to rented network rates. Estimated annual recovery: $6,200.
Total estimated annual revenue recovery: Approximately $75,300, with full recovery on two of the four arrangements expected by month 18.
The engagement fee for the complete analysis, strategy development, carrier communications, and implementation support was recovered in the first four months of improved collections.
What Dr. Marlowe Said
‘The thing that surprised me most wasn’t the money — though that was significant. It was that this had been happening for years. We had experienced, careful people managing our billing. The problem wasn’t human error; it was that no one knew this was something to look for. Having a professional analysis that specifically looks for this kind of exposure was worth it simply for the peace of mind, before we even calculated the financial return.’
Key Takeaways for Practice Owners
This case study illustrates several patterns that apply broadly across practices of similar size and complexity:
- Rented network exposure is common and often undetected for years, even in well-managed practices.
- Experienced billing staff are not equipped to identify rented network arrangements without specialized tools and analysis frameworks.
- The financial impact scales with practice size — larger practices face proportionally larger exposure.
- Multiple resolution pathways exist — and the right strategy depends on the specific arrangement and the practice’s patient care priorities.
- Professional PPO network analysis and negotiation services typically deliver a strong and measurable return on investment.
