Does Delta Dental downgrade fillings? Some plans do and some do not, which makes this a plan level question rather than a carrier level one. Delta Dental is an association of independent member companies, and the employer group that bought the coverage chooses the provisions inside it. Where a plan carries an alternate benefit provision, a posterior composite is paid at the amalgam allowance and the patient owes the difference. Anterior teeth are usually excluded. You confirm it per plan, per member company, before the case is presented.
That is the short answer. The useful part is how to find out which kind of plan you are holding.
What is a downgrade in dental insurance?
A downgrade is a benefit calculated on a less expensive procedure than the one performed. The plan accepts the treatment, then pays as though the cheaper option had been used. You will see it written as an alternate benefit provision or a least expensive alternative treatment provision. The effect is the same in every wording.
Two things get confused with it, and both confusions cost money.
A downgrade is not a denial. Nothing is rejected and no reason code shouts at you. The claim pays. The only visible symptom is an allowed amount lower than the one your estimate used.
A downgrade is not the contractual write off. The write off is the gap between your full fee and the contracted rate, which you agreed to absorb when you signed. The downgrade reduces the basis the benefit is calculated on, and that reduction lands on the patient. Treating it as a write off is how practices give away money they were entitled to collect.
One close relative: a downgrade recalculates the benefit while your submitted code stands, while downcoding means the payer adjudicates a different code entirely. On the remittance the two look nearly identical, so read the adjudicated code, not just the paid amount.
Why the answer changes from one Delta Dental plan to the next
Three layers sit between the name on the card and the way your claim adjudicates. The member company comes first: Delta Dental operates as independent companies by state, each with its own processing policies, fee schedules and provider handbook. The product comes second, since Delta Dental PPO, Delta Dental Premier and the prepaid DeltaCare USA style product carry different allowables and rules, and one card can name more than one. The purchasing group comes third, because a self funded employer buys the plan design it wants. Two patients with the same logo, state and product can therefore have different alternate benefit language.
How to pin it down before the patient sits down
Work in this order, cheapest step first.
- Ask by name during verification. Does this plan apply an alternate benefit or least expensive alternative treatment provision, and to which categories? A generic benefits response tells you basic services pay at 80 percent and says nothing about the basis those benefits are calculated on.
- Ask per category, not once. A plan can apply an alternate benefit to posterior composites and leave crowns alone, or the reverse. One yes or no cannot price a treatment plan.
- Record the reference number and the date. If a downgrade later contradicts what you were told, that record is the entire argument.
- Pull the processing policy manual. Member companies publish a dentist handbook or processing policy document in the provider portal. It states the standing rules on alternate benefits, buildups and multi surface restorations, and does not expire between phone calls.
- Send a predetermination on anything large. It returns the allowed amount line by line for these teeth on this plan, which nothing else does. Turnaround is commonly quoted at two to four weeks. Our guide to automating dental pre-determinations covers keeping that queue out of one person's head, and expediting a dental prior authorization covers cases that cannot wait.
One more check before you bill. Charging the patient the difference for the more expensive material is standard under most PPO contracts, but some agreements require written consent in advance and some states set rules on optional treatment disclosures. As of this writing that varies, so confirm it against your provider agreement and your state dental board or insurance department.
What the downgrade does to a filling estimate
Take a two surface posterior composite, D2392, with an amalgam alternate at D2150. These figures are illustrative, not a fee survey.
| Line | Amount |
|---|---|
| Office fee for the composite | 295 |
| Contracted allowable for D2392 | 180 |
| Amalgam allowable for D2150, used as the basis | 135 |
| Plan pays at 80 percent of 135 | 108 |
| Contractual write off, 295 minus 180 | 115 |
| Patient owes, 180 minus 108 | 72 |
Without the alternate benefit the plan would have paid 144 and the patient would owe 36, so the downgrade moved 36 dollars onto the patient on one tooth. The codes that most often carry an alternate benefit pair up like this:
| Performed | Commonly paid as | Usual exception |
|---|---|---|
| D2391 to D2394, posterior composite | D2140 to D2161, amalgam, surface for surface | Anterior teeth generally exempt |
| D2330 to D2335, anterior composite | Usually not downgraded | Sometimes reduced by surface count |
| D2740, ceramic crown, posterior | Base metal or porcelain fused to metal allowance | Anterior crowns often exempt |
| D2950, core buildup | Sometimes bundled into the crown allowance | Documented loss of tooth structure |
Verify each row against the plan in front of you. This is a list of places to look, not a ruling.
How much do 4 fillings usually cost?
Full fees for a posterior composite are commonly quoted at roughly 150 to 350 dollars per tooth depending on surfaces, region and practice, so four often total between 600 and 1400 dollars before insurance. Use your own fee schedule for the real number, and regional fee data rather than a national average.
The patient's share is a different calculation, and the downgrade is what makes it swing. Below are two one surface and two two surface posterior composites at 80 percent coinsurance, deductible set aside.
| Line | No alternate benefit | With the amalgam alternate |
|---|---|---|
| Contracted allowable, four composites | 660 | 660 |
| Basis the plan calculates on | 660 | 480 |
| Plan pays at 80 percent | 528 | 384 |
| Patient owes | 132 | 276 |
Same four fillings, same network, same coinsurance, and the patient's share doubles. A patient quoted 132 who receives a bill for 276 does not conclude that their plan has an alternate benefit provision. They conclude that your office quoted badly.
Is 200 expensive for a filling?
For a one or two surface posterior composite, 200 dollars sits inside the commonly quoted range across much of the country. A patient asking this is usually holding one of three numbers without knowing which.
If 200 is the office fee, it is ordinary in most markets and the contracted allowable will be lower. If 200 is the contracted allowable, that is what the plan and the patient pay between them. If 200 is the patient's share of a covered filling, something specific produced it: an unmet deductible, an exhausted annual maximum, an out of network claim, or a downgrade. Naming which one turns an argument into an explanation.
Why do dentists not like Delta Dental insurance?
The complaints are consistent, and each has a document that settles it.
Fee schedule levels. Premier and PPO allowables for the same code can differ noticeably. The fix is knowing the exact contracted rate per code before you quote.
Provisions that do not surface at verification. Alternate benefits, missing tooth clauses and frequency limits rarely appear in a standard eligibility response. They live in the plan document and the processing policy manual, and have to be asked for by name.
Processing policies that bundle. Buildups folded into crown allowances and multi surface restorations reduced to fewer surfaces produce shortfalls that look like underpayment and are actually policy.
Payment routing out of network. In some states and plans, benefits for a nonparticipating dentist go to the subscriber rather than the office, which changes your collection plan. Confirm it with the member company before treatment.
None of these is unique to one carrier, and none is secret. They are simply not volunteered.
Does Delta Dental downgrade crowns?
Some plans apply a material based alternate benefit to posterior crowns and pay at a base metal or porcelain fused to metal allowance where a ceramic crown was placed. Others leave crowns alone, and anterior crowns are more often exempt.
Predetermine crowns every time, because the money is hundreds of dollars rather than tens. When the reduction looks wrong, for example applied to an anterior tooth or to a plan you verified as having no alternate benefit, appeal with the dated verification record attached. Our dental claim narrative examples show how to document clinical necessity in language an adjudicator reads, and appealing a denied dental claim for a crown covers the sequence and deadlines.
Catching the ones you did not price
Some downgrades will get past you. The plan changed in January, the group swapped administrators, or nobody asked. The recoverable version is short: the shortfall is caught on the remittance, billed to the patient promptly with an explanation, and written into that plan's record. The uncontrolled version is a posted payment, an automatic write off, and a slow leak nobody measures.
Comparing every allowed amount against what you estimated is the control, and it belongs in your revenue cycle audit. Curo reads the full benefits detail at verification, prices from the downgraded allowable where a plan applies one, and flags remittance lines that come in under the estimate, which is what our payment and EOB reconciliation work is for.
Say it before, not after
Practices that handle downgrades well are not the ones with better appeals. They are the ones where the patient hears one sentence at the chair: your plan pays fillings at the silver filling rate, the tooth colored material costs this much more, and here is why we recommend it.
Said in advance, that sentence almost never stops treatment. Said three weeks later on a statement, it costs you the balance and sometimes the patient.
