Most dental groups have a leased network problem. The ones that know about it are the lucky ones.
The others — the majority — signed a PPO contract years ago, watched claims come in and get paid, and never asked the question that determines their actual reimbursement: which fee schedule is repricing these claims?
The answer is almost never the one they signed.
"Silent PPO" refers to the practice of a payor — one you did NOT contract with — applying a discounted fee schedule to your claims without your knowledge or consent. The "discount" shows up as a write-off on your EOB. Most billing teams process it without question.
It happens because dental insurance operates on a system of leased networks. When you contract with a major payor, you're often not just agreeing to their fee schedule. You're agreeing to allow them to lease your participation to other networks — at fee schedules that may be significantly lower than what you negotiated.
Silent PPO is legal. It's disclosed — barely — in the participation agreements most practices sign without reading. And it's draining dental group revenue at scale.
Here's a concrete example of how a single claim can travel through multiple network layers before reimbursement hits your account:
You agreed to MetLife's fee schedule. You got paid at Careington's rates. The difference never appears on a denial. It shows up as a write-off that looks routine — because it is routine. It happens on every claim.
The repricing happens before the EOB is generated. By the time your billing team sees the remittance, the fee schedule that was applied is already baked in. Unless someone is manually cross-referencing every claim against the correct contracted rate — which no one is — the leakage is invisible.
The EOB might say "MetLife" at the top. The repricing might be Careington's. You'd never know without tracing the claim routing.
Compounding this: most DSOs have participation agreements with 15–30 payors. Each of those payors may have their own leasing arrangements with 3–8 downstream networks. The number of possible routing paths is in the hundreds. No human can track this manually.
Quantifying silent PPO leakage is difficult precisely because it's invisible — but industry estimates consistently put it in the range of 3–8% of total collections for groups that haven't audited their network routing.
For a 10-location DSO doing $8M in annual collections, that's $240,000–$640,000 per year flowing out through write-offs that look legitimate but aren't — because the wrong fee schedule is being applied.
That's not a billing problem. That's a contracting intelligence problem.
The starting point is understanding your routing. For each major payor you participate with, you need to know:
1. Does this plan lease my participation to other networks? Most do. The question is which ones, and under what fee schedule hierarchy.
2. What is the repricing hierarchy? When multiple fee schedules could apply, which one takes precedence? Your direct contract rate, or the leased network rate? The answer determines your actual reimbursement.
3. Which network path is most likely to reprice a claim from this payor? The routing isn't always deterministic — it depends on the patient's specific plan, the employer group, and the state. But there are probability distributions that can tell you where most claims will land.
The goal isn't to terminate every leased network agreement. The goal is to know which ones are costing you money — and renegotiate or exit those specifically.
PayorMap maps the PPO leased network relationships across all major dental payors — giving DSOs and billing teams visibility into the routing paths most likely to apply to each claim, before they sign contracts and after.
Enter any payor into the Routing Query and you'll see a probability distribution of which network paths that plan uses, which fee schedules each path applies, and what the implied repricing impact is.
It's the audit you should have done at contract signing — available in 10 seconds instead of 6 weeks.
