# Does Delta Dental downgrade crowns?

> Less often than fillings. As of September 2026, 8.5% of paid crowns on Delta Dental plans were paid at a cast-metal alternate benefit — 170 of 2,004 lines across 15 practices — and 57 of those 170 carried no downgrade remark. Which molars are in scope, and what the substitute is, changes by Delta member company.

Delta Dental downgrades crowns on some plans, and as of September 2026 it does so on 8.5%
of paid crown lines — roughly half as often as it downgrades posterior composites. What
makes Delta's crown rule harder to work with than its filling rule is that 57 of those 170
downgrades carried no downgrade remark, and that the tooth scope is drawn differently by
each member company: one state spares the upper first molar, another reaches forward to
the lower first molar, and the substitute is a porcelain-fused-to-high-noble crown in one
and gold without porcelain in the next.

## What we measured

| Delta Dental | Paid lines | Practices | Stated on the remittance | Silent | Downgraded |
|---|---|---|---|---|---|
| Crown (D2740–D2752) | 2,004 | 15 | 113 | 57 | **8.5%** |
| Bridge retainer / pontic | 196 | 13 | 31 | 16 | 24.0% |
| Posterior composite | 7,897 | 21 | 1,039 | 145 | 15.0% |

A line is one procedure on one claim; these are paid explanation-of-benefits lines pooled
across the practices Kaylie serves, all Delta member companies together, measured on
8 September 2026. "Silent" means the remittance carried no downgrade remark, but the
allowed amount was below the contracted fee for the billed code, or the carrier issued a
substitute line. A third of Delta's crown downgrades are in that state — a materially
higher share than its filling downgrades, where 145 of 1,184 were silent.

## What Delta Dental's own policy says

The most specific crown-downgrade sentence any carrier publishes belongs to Delta, in the
"Optional Services" list that appears word-for-word in Pennsylvania, Georgia and California
policies:

> "porcelain, resin or similar materials for crowns placed on a maxillary second or third
> molar, or on any mandibular molar (an allowance will be made for a porcelain fused to
> high noble metal crown)."

— [*Delta Dental of Pennsylvania Individual & Family PPO Preferred Plan*](https://www1.deltadentalins.com/content/dam/ddins/en/pdf/hcx/2024/dd-dd-pa-i-fam-prf-24.pdf), 2025

Read the tooth list carefully: upper second and third molars, and every lower molar. The
**upper first molar is not in scope**. The same list also names "a crown where a filling
would restore the tooth" as an Optional Service — a separate rule that re-prices a crown to
a restoration rather than to a cheaper crown.

Delta Dental of Oregon draws the line one tooth further forward on the lower arch and
substitutes a different material:

> "Porcelain crowns are considered cosmetic dentistry if placed on the upper second or
> third molars or the lower first, second or third molars. Coverage is limited to gold
> without porcelain, and you must pay the difference."

— *Delta Dental PPO 1000 Oregon Group Dental Plan Handbook*, 2026

Two Delta companies, two different answers to "is my lower first molar crown downgraded?".
Others state a coverage boundary instead of a downgrade: Delta Dental of Virginia's Classic
plan covers "Porcelain/Ceramic/Resin fused to metal crowns… on front teeth, premolars and
1st 2 upper molars" (*Delta Dental of Virginia Individual and Family Classic Plan*, undated),
and Delta Dental of Wisconsin covers porcelain veneers on crowns "only
on the six front teeth, bicuspids, and upper front molars".

One more Delta rule affects children rather than adults: "A prefabricated stainless steel
crown with resin window is a benefit only on anterior primary teeth. If submitted for a
posterior primary tooth or for a permanent tooth, an alternate benefit allowance for
prefabricated stainless steel crown… is made. The difference… is denied and chargeable to
the patient." (*2026 Delta Dental Dentist Handbook*, Delta Dental of Arkansas.)

## Why it depends on the plan group

Within a single member company, the crown clause can drop out of the plan entirely. Delta's
Georgia Basic tier carries only the composite example from the Optional Services list; the
full four-item list, including the crown clause, appears in the Preferred and Premium tiers
— because a tier that sells no Major coverage has no crown benefit to re-price. So the
question is not "does Delta downgrade crowns" but "does this group's plan, from this member
company, at this tier, downgrade crowns". Measured across 2,748 employer groups in August
2026, the tooth-scope answer is settled within the group 97.4% of the time and at carrier
level only 77.6%.

## What to do

- **Compare the allowed amount to your contracted fee for the crown code you billed.**
  With a third of Delta's crown downgrades carrying no remark, the money is the only signal
  on those lines.
- **Note the arch and the tooth number, not just "molar".** Under the Pennsylvania,
  Georgia and California wording an upper first molar crown is not downgraded; under
  Oregon's, a lower first molar crown is. A note that says "molars" loses the case you
  will argue about.
- **Do not read a cast-metal substitute as a cheap one.** Delta's named target is a
  porcelain-fused-to-high-noble crown in three states and gold without porcelain in Oregon;
  the point of the substitution is the material specified in the contract, not a lower
  number.
- **Record the answer against the employer group number, with the member company and the
  plan tier beside it.** "Delta Dental" alone is not a plan.
- **Quote the patient the difference between the two allowed amounts before treatment.**
  Delta's own wording puts that difference on the patient, in network or out.
