Is a lower partial denture covered by insurance?
Usually yes, as a major service at around 50%, when the teeth it replaces were lost after the plan began. A lower partial (code D5214) is a removable piece with a cast metal frame that fills in missing bottom teeth and clips to the natural ones next to them. When each tooth came out matters as much as the plan percentage.
50%
Major, check the extraction dates
One per arch
Most plans pay for one lower prosthesis per window, partial, bridge or denture. A bridge paid 3 years ago blocks a new partial on that arch.
Opposite of D5110
A lower partial often pairs with a full upper denture. Both are major, both hit one annual maximum, and 50% of two appliances rarely fits under it.
Paid as D5212
Some plans approve the metal frame but pay the plastic-base lower partial fee instead. The gap lands on the patient unless you quoted it first.
Effective date
The check returns the plan's coverage dates, major percentage and remaining maximum in under a second. Compare them to the extraction dates before the impression, not after.
What would a real check show for this patient's D5214?
Pick a sample plan and type your fee. This is the visibility a real-time check gives the desk for every actual patient, in under a second.

Why lower partials get denied
What happens after the lower partial
The lower partial rests on the ridge, and as the ridge changes a reline becomes its own claim (D5761 for a lower partial), usually allowed once every 12 to 36 months and never inside the first 6 months. If a clasp tooth is lost later, adding a tooth to the frame is a separate claim too, and by then the plan year's maximum has often gone to the partial itself. Quoting the remaining maximum and the reline window on delivery day, from a real check, stops the surprise.
D5214, quick answers
Does insurance cover a lower partial denture?
Most plans cover D5214 as a major service at around 50% after the deductible, as long as the missing tooth clause and waiting period do not apply.
The patient lost the teeth years ago. Does that matter?
Yes. If they were lost before the plan's effective date, many plans exclude replacing them. Verify the dates before treatment.
How often will a plan pay for a new lower partial?
Typically once every 5 to 10 years for that arch, and any other prosthesis on the lower arch in the window usually counts.
Why did the payment come back lower than expected?
The plan may have paid the plastic-base (D5212) fee as an alternate benefit. Checking D5214 against the plan before treatment shows the percentage it will actually apply.
Can the lower partial and an upper denture be done together?
Yes, but both are major and share one annual maximum. Check the remaining maximum before booking the second appliance.
