PPO Write-Offs: Your Insurance Carrier Is Stealing $42K/Year Per Doctor

Forty-two thousand dollars is what a lightly participating general dentist hands back to carriers in a single year, and that's the conservative read. The U.S. Bureau of Labor Statistics puts the median annual wage for general dentists at $170,950 as of May 2025, which means the write-off alone is roughly a quarter of what the government says the job pays. The carrier doesn't take it at gunpoint, though, and that's the part owners refuse to sit with.

Here's our thesis, and plenty of owners will hate it: the write-off isn't theft, it's rent, and most practices are paying that rent on patients who were already in the neighborhood. If the discount bought you nothing you wouldn't have gotten anyway, the carrier didn't steal from you. You volunteered. That distinction matters because owners who believe they're being robbed go looking for a villain, and owners who understand they're paying rent go looking for a lease negotiation. Only one of those two gets paid.

Where the $42,000 Actually Comes From

Start with the discount rate, because it's worse than most owners admit on paper. The now-discontinued ADA Survey of Dental Fees found participating-PPO write-offs averaging 30% to 40% of production, and at a 35% blended rate a practice producing $1,000,000 at full fee gives back $350,000 a year. Dental Claim Support, working from a live client file, describes a practice sitting at a 40% write-off rate, which it calls twice the recommended maximum of 20%, and runs the arithmetic plainly: a 30% write-off on $100,000 of production is $30,000 gone.

Now scale that to one doctor with modest exposure. Say the practice bills $700,000 a year at its own fee schedule and only 20% of that production sits under PPO contracts. That's $140,000 of contracted production. At a 30% write-off, the adjustment is $42,000. Against the BLS median wage, that single line item equals about 25% of a dentist's annual pay.

That's the floor, not the headline. The National Association of Dental Plans reports that DPPO products carry 89% of total commercial dental plan enrollment as of year-end 2024, so a practice at 20% PPO participation is unusual, not typical. Run the same $700,000 practice at 60% PPO production and the contracted base is $420,000. At 35% that's $147,000 written off in twelve months. The $42,000 in our headline is the number for the doctor who thinks the problem doesn't apply to them.
