THE MECHANICS
How a schedule works
Every dental fee ties back to a CDT procedure code — D0120 for a periodic exam, D2392 for a one-surface posterior composite, and so on through the full code set. A fee schedule is the rate card that maps each code to a dollar figure for a given payer, plan, or practice.
Three numbers usually sit side by side for the same procedure. Your UCR — usual, customary, reasonable — fee is what you'd charge a self-pay patient with no insurance involved, set by your own market and overhead. Your PPO fee schedule is the discounted rate you contractually accept from an in-network plan, procedure by procedure, in exchange for being listed as a participating provider. Your fee-for-service rate is what any out-of-network or cash patient pays — typically your UCR, sometimes adjusted for competitive positioning.
The PPO schedule gets negotiated once, usually at credentialing, then revised by the carrier on its own renewal cycle. Reimbursement can move down without warning; it rarely moves up. Nothing in a standard participating-provider contract requires the payer to ask before cutting a code's rate, which is why reading the rate-change clause matters as much as reading the fee list itself.
THE COMPARISON
Comparing PPO and fee-for-service billing
The gap between the two models is the whole decision. A PPO fee schedule typically reimburses 30–50% below UCR rates for the same procedure code — the carrier trades you patient volume for a fixed discount, locked in at credentialing.
Fee-for-service flips the trade: you set the price, the patient or their out-of-network benefit pays it, and nothing caps the reimbursement but your own market. The tradeoff is volume — FFS patients book because of trust and convenience, not because your name sits on a network list.
That tradeoff shows up in the national numbers. FFS practice share grew from 6% to 16% of all dental practices as reimbursement pressure mounted, and 50.3% of owners now name low reimbursement their top operating challenge. The schedule itself hasn't changed shape — codes, fees, a contract — but what practices choose to do with it has.
THE DECISION
Why the schedule decides your revenue
When a PPO cuts a fee schedule, the practice absorbs the difference on every claim until it renegotiates or exits the network. That calculus is reshaping participation nationwide: 35% of dentists say they're very or somewhat likely to drop at least one PPO network, and earlier ADA polling put the share considering some kind of network exit as high as 42.5%.
Dropping a plan doesn't mean closing the operatory chair — it means re-pricing it. Patients on the dropped plan either pay your fee-for-service rate, use their out-of-network benefit, or leave for another in-network provider. Practices that make this move well model all three outcomes before they send the termination letter: current PPO volume by procedure mix, expected fee-for-service retention, and the marketing cost to backfill whoever doesn't stay. Side's guide to dropping a dental PPO walks through that model step by step — the real math a fee schedule change puts you through, not a surface-level pros-and-cons list.

FAQ
Common questions.
What's the difference between a fee schedule and UCR fees?
A fee schedule is the negotiated rate for a specific payer, procedure by procedure. UCR — usual, customary, reasonable — is your own market rate for self-pay patients, the number a fee schedule is usually discounted against.
Can a PPO lower my fee schedule without my consent?
Most participating-provider contracts let the carrier revise reimbursement rates on renewal, with notice but not negotiation. Read the rate-change clause before you sign — it's the single most consequential paragraph in the agreement.
Is fee-for-service more profitable than PPO participation?
Per procedure, yes — fee-for-service pays your full rate instead of a discounted one. Per chair-hour, it depends on whether your fee-for-service pricing costs you the patient volume the PPO network was delivering.
How do I know if dropping a PPO makes sense for my practice?
Model your current PPO claim volume by procedure, expected fee-for-service retention, and the marketing cost to backfill lost patients. Side's PPO guide sets out that calculation step by step.
Does a fee schedule apply to every procedure the same way?
No — carriers set rates code by code, and some procedures like hygiene and exams are discounted less than others like crowns and implants. Reviewing your schedule by procedure mix, not as one blended number, is how you find where the real losses sit.
