How to Value a PPO-Heavy Dental Practice in 2026

PPO-heavy dental practices are the bread and butter of American dentistry. Roughly 70% of the general practices I see in the M&A market derive 60-90% of their collections from in-network PPO contracts. These practices are profitable, stable, and salable — but they trade at very different multiples than fee-for-service practices, and the gap has widened over the last five years as dental insurance fee schedules have stagnated while overhead has climbed.

If you're running a PPO-heavy practice and thinking about an exit, understanding exactly how buyers adjust for insurance write-offs is the single most important thing you can learn. It's the number that determines whether you're selling at the top or the bottom of the range.

The Mid-Range Multiple Reality

PPO-heavy dental practices typically sell for 2-3.5x SDE to private buyers, or 60-80% of annual collections. For platform-scale practices going to DSOs, expect 6-9x EBITDA for add-ons and 9-11x EBITDA for platform deals.

That's the middle of the dental market — below the 3-6x SDE that fee-for-service practices command, but well above the 1.5-3x SDE that Medicaid-heavy practices get. The spread within the PPO range is wide, though, and where your specific practice falls depends almost entirely on which PPO contracts you're in and what your actual write-off percentage is.

The Write-Off Analysis Buyers Actually Run

When a sophisticated buyer or DSO diligence team evaluates your practice, the very first analysis they run is a contract-by-contract write-off review. Here's what it looks like.

They pull your last 12 months of production by payer. They look at your gross production (what you billed at your office UCR fees), then your contractual adjustments (insurance write-offs), then your net collections. The difference between gross and net, divided by gross, is your blended write-off percentage.

For PPO-heavy practices, blended write-offs typically run 28-45%. A practice writing off 28% is in a good position — likely in premium PPOs like Delta Dental Premier, or has a smart network participation strategy. A practice writing off 42% is bleeding value every single day and will be priced accordingly.

Every 5 percentage points of write-off reduction translates roughly to a 10-15% increase in SDE, because the overhead structure stays the same while collections climb. That's why this number dominates buyer underwriting.

Which PPO Contracts Actually Matter

Not all PPOs are created equal, and buyers know the pecking order cold. The contracts that matter most in 2026:

Delta Dental Premier is the gold standard PPO contract. Premier reimburses at close to usual-and-customary rates with minimal write-offs (often under 10%). Practices with 20%+ of their book in Premier trade at the top of the PPO range. Unfortunately, Delta closed Premier to new providers in most states years ago, so if you're not already in it, you can't get in.

Delta Dental PPO (the standard PPO, not Premier) is the workhorse contract in most markets. Write-offs run 25-35% depending on state. Practices heavily dependent on Delta PPO are salable but hit the middle of the range.

Cigna DPPO, MetLife PDP, Aetna PPO, and United Concordia are the second tier. Write-offs run 30-40%. These are fine contracts to be in as part of a diversified mix but problematic if they're your dominant payer.

Guardian, Principal, and Ameritas tend to have moderate write-offs (25-35%) and are generally viewed favorably by buyers.

Humana and Careington discount plans are the contracts most likely to hurt your valuation. Write-offs can hit 45-55%, and buyers will strongly encourage you to drop them before closing.

The Fee Schedule Renegotiation Lever

Here's something most dentists don't realize: PPO fee schedules are negotiable if you're persistent and you understand the leverage. Practices that have successfully renegotiated fee schedules in the last 24 months show up to market with 3-5% higher collections on the same production base, which flows directly to SDE.

The playbook that works: formally request a fee review from every PPO you're contracted with every 18-24 months. Cite your production volume, your A+ provider rating, your years of participation, and any meaningful changes in your local market. Threaten to leave the network if the response is inadequate. For Delta Dental, most other insurers, and especially regional BCBS plans, this process yields 3-8% fee bumps more often than dentists expect.

If you're 12-24 months from selling, this is the single highest-ROI exercise you can run. A 5% fee bump on $1.8M of PPO collections is $90K of additional revenue with zero additional overhead — which is $90K of additional SDE, which at a 2.8x multiple is $248K of additional practice value at closing.

Dropping PPOs Before a Sale

Some brokers will tell you to drop your worst PPOs 12 months before going to market to "clean up" the payer mix. This is sometimes good advice and sometimes terrible advice, and the difference depends on patient stickiness in your specific market.

Dropping a PPO that represents 8-12% of your collections typically results in losing 40-60% of those patients immediately, followed by another 10-20% over the next six months. If your overhead is fixed (which it mostly is), losing 8% of collections often doesn't increase SDE in a clean way — it just moves it sideways while you wait to rebuild with patients from better payers.

Dropping a PPO where the write-offs are above 45% and the production share is under 10% is almost always value-accretive. Dropping a PPO where write-offs are 35% and production share is 25%+ is almost always value-destructive.

The sellers I've seen do this well spend 18-24 months on a gradual transition: stop taking new patients from the bad PPO, raise their office fees, push existing bad-PPO patients toward in-house membership plans, and only formally terminate the contract once the production share has naturally fallen to single digits.

The DSO View of PPO Practices

PPO-heavy practices are the primary diet of most large dental DSOs. Heartland Dental (KKR-backed), Aspen Dental (backed by Ares and Leonard Green), Pacific Dental Services, Smile Brands, Dental Care Alliance, and MB2 Dental all acquire PPO-heavy practices aggressively. North American Dental Group (Jacobs Holding), Western Dental (New Mountain Capital), and 42 North Dental (Blackstone) round out the major platforms.

DSO value creation in PPO practices comes from three levers buyers will quietly bake into their offer: (1) renegotiating your PPO contracts to their larger corporate fee schedules, adding 3-8% to collections; (2) centralizing back office functions like billing, credentialing, and HR to cut overhead 4-8%; and (3) adding specialty services like implants and Invisalign they can staff with traveling specialists. The DSO keeps most of that upside, but they'll pay a premium over a private buyer because they can extract it.

Typical DSO offer on a PPO-heavy practice: 7-9x EBITDA for a bolt-on in a desirable market. Platform deals with multiple locations and strong doctor retention agreements go as high as 11x.

The Math on a Typical PPO Practice

A representative deal: single-location general practice in a middle-class suburb, $1.8M in collections, 75% PPO / 15% FFS / 10% Medicaid, 35% blended write-offs, $470K SDE (26% margin), one owner, two hygienists, five operatories.

Private buyer outcome: 2.5-3x SDE, or $1.18M-$1.41M. Most likely closing price around $1.3M with SBA 7(a) financing.

DSO outcome: after replacing owner comp with a $190K associate, EBITDA is roughly $245K. At 7x, that's $1.7M, with 15-25% held back as equity rollover or earnout. The DSO deal nets a higher headline number but with more complexity and multi-year clinical commitments.

Either outcome is substantially below what a comparable FFS practice would get — roughly $2M+ less — which is why reducing write-offs and shifting payer mix is the single most valuable thing a PPO-dependent dentist can do 2-3 years before selling.

Preparing a PPO Practice for Sale

The prep list for PPO-heavy practices looks like this: run the payer-by-payer write-off analysis yourself so you know your number before a buyer does. Renegotiate every PPO contract for which you have leverage. Drop the worst 1-2 plans only if it can be done cleanly. Build a production dashboard showing trending per-payer economics. And get associate coverage in place so the practice can keep running in a transition.

For context on how your practice fits into the broader dental M&A picture, see our dental practice valuation overview. If you're comparing offers that use different cash flow definitions, the SDE vs EBITDA breakdown will help you translate private buyer offers and DSO offers into apples-to-apples terms.

The Bottom Line

PPO-heavy dental practices sit in the middle of the dental M&A market, and the buyers who underwrite them care about exactly one thing: your blended write-off percentage and the contracts driving it. Sellers who spend 18-24 months optimizing their payer mix, renegotiating fee schedules, and documenting the trend data consistently get 15-25% higher offers than sellers who bring a practice to market with the same write-off percentage they've carried for a decade. The math is boring but it's the math that pays you.
