UCR fees and dental fee schedules

UCR fees, short for usual, customary, and reasonable fees, are the fee amounts a dental insurance carrier decides are typical for each procedure in a geographic area and uses to calculate what it will pay, set by the carrier itself rather than by the ADA or the dental office. They are not the same as a dental fee schedule, the practice's own list of full fees per CDT code, or a PPO fee schedule, the reduced fees a dentist has agreed by contract to accept. The three get mixed up constantly, partly because several practice management systems label the office's own fee list "UCR." This entry keeps them apart, shows how an unreviewed fee schedule lowers production at a single office and at every office in a group, and gives an office manager a way to check in one afternoon.

What are UCR fees?

UCR stands for usual, customary, and reasonable, and in dental insurance it names the fee level a carrier considers typical for a procedure in a given area. The carrier pays a percentage of that level on a claim. The three words are usually treated as one idea, but the usual fee is what a dentist actually charges, while customary and reasonable are the carrier's own determination. Each carrier builds its UCR figures from its own claims data and does not publish the method, so two plans in the same city can reach different amounts for the same code. The ADA does not set UCR fees, and neither does your office.

UCR shows up day to day on out-of-network and indemnity claims. The plan pays its percentage of the UCR amount, or of the submitted fee if that is lower, and the patient owes the rest where balance billing is allowed. If your office fee is below the carrier's UCR for a code, the carrier pays its percentage of your lower fee and the difference is never billed. The carrier's number is invisible until the explanation of benefits arrives, which is why UCR is not something the front desk enters into the practice management system.

How is a UCR fee different from an office fee schedule and a PPO fee?

Three separate numbers can attach to one procedure, each set by a different party. The office fee schedule is the practice's own full fee for every CDT code: what a fee-for-service patient pays, what is booked as gross production, and what goes on every claim. The PPO contracted fee is the reduced fee a dentist agreed to accept for that code in exchange for being in-network; the gap between the office fee and the contracted fee is the PPO write-off, also called the adjustment. UCR is the carrier's internal benchmark when there is no contract. One confusion is worth naming: Open Dental, Dentrix, and other systems label the standard office fee schedule "UCR" or "Office (UCR)." That list is yours, not the carrier's.

Only one of the three is under the practice's control, and it is the one the other two are measured against. Write-off percentage is computed against the office fee, gross production is booked at the office fee, and most PPO contracts pay the lesser of the submitted fee and the contracted fee. A stale office fee schedule therefore distorts every number downstream of it, including the production and collections figures a practice runs on.

How does fee-schedule drift erode production?

Fee-schedule drift is what happens when the office fee schedule is left alone for years while the practice's costs, its contracted fees, and area fees all move. Practices commonly review and update the office fee schedule once a year, often in the fourth quarter with the change effective January 1. A practice that skips the review is producing every procedure at a fee set two or three years ago, and the loss lands in four places.

• Fee-for-service and out-of-network patients pay the stale fee directly. That is collected cash, not a paper number.
• Out-of-network claims are paid on the lesser of your fee and the carrier's allowable. Where your fee sits below the allowable, the carrier keeps the difference.
• PPO write-off percentage is understated. The discount is measured against a low office fee, so every contract looks better than it is and renegotiation never reaches the top of the list.
• Any code where the office fee has fallen below a contracted fee is paid at the office fee, since contracts commonly pay the lesser of the two.

Worked example (illustrative figures). A single office produces $1.2 million a year at office fees last updated three years ago. Suppose an annual review would have moved fees about 2 percent a year, so the schedule now sits roughly 6 percent below where it would be. Gross production is understated by about $72,000 a year, which distorts goals, bonuses, and per-provider comparisons. The cash effect is smaller but real: if 30 percent of production is fee-for-service or out-of-network and paid at the office fee, the office collects about $21,600 a year less than it would have, before counting any code that has slipped below a contracted fee. Now take a four-office group where each location keeps its own schedule: one is current, one is two years old, two are three years old. On the same assumptions the group gives up around $50,000 to $65,000 a year in collections. Worse, its per-office write-off percentages are no longer comparable, because each office measures its PPO discount against a different baseline. The office with the oldest fees reports the lowest write-off rate and looks like the best-run location. The drift compounds because each skipped increase is applied to every procedure of every following year.

How do you check your own fee schedule?

The check fits in one afternoon and needs only the practice management system and a spreadsheet. The goal is not to set new fees on the spot but to find out whether the schedule is current and, if not, roughly what that is costing.

1. Pull the top 25 codes by volume for the last 12 months from the production-by-procedure report. Exams, radiographs, prophylaxis, periodontal maintenance, posterior composites, and crowns usually carry most of production.
2. Find the date the office fee schedule was last changed. Most systems keep a fee history; if nobody in the office knows, that is itself the finding.
3. Next to each code, list the office fee and the contracted fee for the two or three PPO plans with the most patients.
4. Compute the write-off percentage for each code and plan: office fee minus contracted fee, divided by office fee. Flag every code where the office fee is at or below a contracted fee.
5. Multiply last year's volume for each code by the office fee to see what the top 25 produce, then by the fee-for-service and out-of-network share to see what a fee change would actually collect.
6. Decide. If the schedule is more than 12 months old, put the review on the calendar. If any code sits below a contracted fee, correct it this week. If a plan's write-off runs past the owner's threshold, put that contract on the renegotiation list.

For a group, add two columns, last-updated date and write-off percentage per plan, and run the sheet per office; the gap between offices is the point. It also cleans up the numbers everyone else depends on: treatment acceptance rate measured in dollars, per-provider production, and the patient portion quoted from a predetermination all start from the office fee.

Frequently asked questions

What are UCR fees?

UCR fees, short for usual, customary, and reasonable, are the fee amounts a dental insurance carrier considers typical for a procedure in a geographic area and uses to calculate what it pays on out-of-network and indemnity claims. Each carrier sets its own UCR figures from its own data and does not publish the method. The ADA does not set them.

How is a UCR fee different from an office fee schedule and a PPO fee?

The office fee schedule is the practice's own full fee per CDT code. The PPO contracted fee is the reduced fee a dentist agreed to accept in-network, and the gap between the two is the write-off. UCR is the carrier's internal benchmark for out-of-network payment. Only the office fee is set by the practice, and some software labels it "UCR."

How does fee-schedule drift erode production?

When an office fee schedule goes unreviewed for years, every procedure is produced at a stale fee. Fee-for-service and out-of-network patients pay the lower fee directly, out-of-network claims are paid on the lesser of your fee and the allowable, write-off percentages are understated, and any code that falls below a contracted fee is paid at your lower fee.

How do you check your own fee schedule?

Pull the top 25 codes by volume for the last year, find the date the office fee schedule was last changed, list the office fee and the main PPO contracted fees for each code, compute the write-off percentage, flag codes at or below a contracted fee, and decide whether to review fees, fix codes, or renegotiate.
