Every endodontic practice sits somewhere on a spectrum from heavily insurance-dependent to largely fee-for-service, and where you sit affects both what you earn now and what the practice is worth later.
Insurance-driven volume brings a steady case flow but at negotiated rates, with the collection friction of claims, narrowing, and delays. Fee-for-service brings higher realized fees and cleaner collections, but requires referral strength and patient willingness to pay.
On margin, the fee-for-service end typically collects a higher percentage of production with less administrative cost per case. The insurance end trades some of that margin for predictable volume.
At sale, the mix shows up in the multiple. The ADA 2024 data put fee-for-service practices near 1.3 times gross and heavily discounted insurance practices closer to 0.9 times. Payer mix is one of the levers behind that spread.
The point is not that one model wins. It is that the mix is a deliberate strategic choice with measurable financial consequences, and most owners drift into their mix rather than choosing it. Knowing what yours costs and earns lets you decide on purpose.
