Benefits and Eligibility

How can we obtain benefit information for our patients without waiting on the phone?

There are two easy-to-use options available:

  • Our interactive voice response (IVR) system allows you to use your touch-tone phone to obtain eligibility and benefit information, and claim status. You'll also be able to elect to have the benefits said back to you, by choosing the speak back option. Our IVR also includes the ability to have the information you request faxed directly to your office for eligibility and benefit information, claim status or the status of unpaid claims we've received within the past 60 days. The IVR flow chart can be found by clicking here.
  • You can also go to the secured section of our website and check patient benefits, claim status and verify the amount of your payment voucher.

My benefits page is not printing correctly, how do I get everything on the page to display when printing?

To view all benefits, change your print preferences to landscape. This allows all of the information to fit on the page.

The Interactive Voiced Response System (IVR) states that there is an Eligibility through Date of 06/30/2014, what does this mean?

The eligibility through date on the fax back indicates the system is able to confirm eligibility and benefits through the end of the month. If the individual you are inquiring about has not had any coverage/employment changes after the end of the month, they will still be eligible for coverage.

Is there a missing tooth clause?

No, we don't have a missing tooth clause.

Can all four quadrants be done on the same day for procedure code D4341?

No, no more than two quadrants can be done on the same day.


What is the claims mailing address?

Our claims mailing address is:

Delta Dental of Washington
P.O. Box 75983

What if there's additional information I feel is pertinent to processing a specific claim?

These “key words” will stop a claim for review of additional information.

What is the process of submitting Orthodontia claims?

When submitting a full case set-up, it is not necessary to submit claims for monthly or quarterly payments. In fact, it is important that you do NOT send continuation claims for the remainder of treatment. Delta Dental will set those up automatically and pay them on schedule. If you are not receiving payments, call Delta Dental Customer Service at (206) 522-2300 or 1-800-554-1907. When submitting your full case set-up claim, please be sure to include:

  • The banding date
  • The total treatment fee
  • The down payment
  • The estimated number of treatment months (not payment months)
  • The monthly fee

Where can I periodically review information about the Clinical Review process at Delta Dental?

Clinical review information is available by selecting the Clinical Information drop down in the menu, after you login to your account.

If I submitted incorrect information on a claim, what is the best way to submit a corrected claim so I don’t have to call customer service?

If you need to submit a corrected claim, please make sure you clearly indicate on a new claim form that it is a corrected claim and include a narrative with the corrected information. (For example: Claim #123456789123456 submitted with tooth #15 in error. Please reprocess D7140 using tooth #16.) If the additional or corrected information is not submitted with a corrected claim form, it will be returned to your office.

If my patient has Dual Delta Dental Coverage do I need to submit two claim forms?

No, only one claim needs to be submitted as long as all the Secondary Coverage information is filled out under the other coverage section of the claim form.

Should I highlight important information on claim forms before sending them in?

Highlighting data on the claim forms causes that information to be unreadable when the claims are scanned. Please do not highlight any information on them prior to submitting them.

How long should I wait to receive payment or denial on a claim before I resubmit the claim or contact customer service?

Delta Dental has 30 days to process claims. For claims that have not received a payment or denial, please wait 30 days before resubmitting them or calling customer service to inquire about their status. Resubmitting the claims may cause additional claim volume and can delay the payment or denial of the claims.

Are there any restrictions to sealants?

Sealants are covered on permanent molars with no restorations or decay on the occlusal surface.

Should I include the primary carrier’s explanation of benefits (EOB) when submitting a claim to Delta Dental if Delta Dental is the secondary carrier?

Yes. You should always include the primary carrier’s EOB when submitting your patients’ claims to us if we are secondary. This will reduce requests for additional information and help ensure that your claims are processed quickly and accurately.

If I am a Delta Dental member dentist, which networks do I belong to?

When you become a member dentist with Delta Dental, you are automatically a member of the Delta Dental Premier® network. You must apply separately for any other network(s) you would like to join. If you're not sure which networks you have joined, you can use the "Find a Dentist" capability on our website to double check. Click the Refer a patient link under Provider Tools and search for yourself; the results will display every network you currently belong to.

I am a member at one dental office. Does that mean I'm automatically a member at all of my offices?

No. Delta Dental membership, and membership in any provider network, is per location. If you want to be a member dentist in any or all of our networks at multiple locations, you must apply separately for each location.

Do dental associates working under my Tax ID Number need to be members?

No. Your employees do not need to be member dentists, but this could result in their claims paying as non-member claims, using non-member fees. This is especially true for claims processed in states other than Washington. Also, most Delta Dental plans pay non-member claims directly to the patient instead of to the dentist.
