Is a porcelain crown covered by dental insurance?
Usually yes, but only as a major service, which most plans pay at around 50% after the deductible, and only once any waiting period has passed. A porcelain crown (code D2740) is a tooth-colored cap that covers the whole tooth, used to hold together a tooth that is cracked, badly broken down, or has had a root canal.
50%
Major service, after any waiting period
5 to 10 years
Once per tooth. The clock starts at the old crown's seat date, even if another office placed it, so ask before you quote.
6 to 12 months
The major waiting period on new plans. A patient who switched plans in January may have zero crown coverage until summer or later.
Molar downgrade
Many plans pay porcelain on a back tooth at the metal crown allowance. The patient owes the difference, and it is not a denial.
Max remaining
A crown at 50% can use up a big share of the annual maximum. One check shows the remaining max, deductible, and waiting period before the patient asks.

When D2740 is the right code
- Tooth is cracked, broken, or heavily filled
- Root canal done and the tooth needs full coverage
- Old crown is failing and past the plan's window
- Crown is all porcelain or ceramic, no metal
Documentation payers expect
A current X-ray showing the damage or the old restoration, notes on why a filling would not hold, and the seat date. Plans with a molar downgrade decide by tooth number, so it has to be right.
Why porcelain crowns get denied
What happens after the crown
The surprise here usually arrives as a short payment, not a denial: the plan paid a back tooth at its metal crown rate and the patient owes the gap. After the seat, that tooth is locked out of another crown for 5 to 10 years, and a big piece of the annual maximum is gone. A loose crown later is D2920; a break under it is D2950 or D3330. Quoting the downgrade and the remaining max on prep day, after one check, keeps the seat visit quiet.
D2740, quick answers
Does insurance cover a porcelain crown?
Most plans do, as a major service at around 50% after the deductible, once any waiting period has passed.
How often will a plan pay for a crown on the same tooth?
Typically once every 5 to 10 years per tooth, counted from the old crown's seat date, even if a different office placed it.
Why did the plan pay less than 50% on a back tooth?
Many plans downgrade porcelain on molars to their metal crown allowance. The plan pays 50% of that lower number and the patient owes the rest.
Is a crown covered on a brand-new plan?
Usually not right away. Major waiting periods of 6 to 12 months are common, and the check shows the end date before you schedule the prep.
When does the plan pay, prep or seat?
Most plans pay on the seat date. If the deductible or plan year resets between the two visits, the patient's share changes.
