Appeals of Denied Claims How to contact us DDWA will accept notice of an Urgent Care Request or Appeal if made by you, your covered dependent, or an authorized representative orally by contacting us at the telephone number below or in writing directed to Delta Dental of Washington, P.O. Box 75983, Seattle, WA 98175-0983. You may include any written comments, documents or other information that you believe supports your claim. For more information please call 1-800- 650-1583. Authorized Representative You may authorize another person to represent you or your dependent and receive communications from DDWA regarding your specific appeal. The authorization must be in writing and signed by you. If an appeal is submitted by another party without this authorization, a request will be made to obtain a completed Authorized Representative form. The appeal process will not commence until this form is received. Should the form, or any other document confirming the right of the individual to act on your behalf, i.e., power of attorney, not be returned, the appeal will be closed. Informal Review If your claim for dental benefits has been completely or partially denied, you have the right to request an informal review of the decision. Either you, or your authorized representative (see above), must submit your request for a review within 180 days from the date your claim was denied (please see your Explanation of Benefits form). A request for a review may be made orally or in writing and include the following information: • Your name and ID number • The claim number (from your Explanation of Benefits form) • The name of the dentist DDWA will review your claim, make a determination within 14 days of receiving your request, and may take up to an additional 16 days with the delivery of this notice, for a total of 30 days. DDWA will send you a written notification of the review decision and information regarding any further appeal rights available should the result be unfavorable to you. Upon request, you will be granted access to, and copies of, all relevant information used in making the review decision. Informal reviews of wholly or partially denied claims are conducted by persons not involved in the initial claim determination. Formal Review If you are dissatisfied with the outcome of the informal review, you may request in writing that your claim be reviewed formally by the DDWA Appeals Committee. This Committee includes only persons who were not involved in either the original claim decision or the informal review. Your request for a review by the Appeals Committee must be made within 90 days of the post-marked date of the letter notifying you of the informal review decision. Your request should include the information noted above plus a copy of the informal review decision letter. You may also submit any other documentation or information you believe supports your case. The Appeals Committee will review your claim and make a determination within 30 days of receiving your request, and send you a written notification of the review decision. Upon request, you will be granted access to, and copies of, all relevant information used in making the review decision. Whenever DDWA makes an adverse determination and delay would jeopardize the eligible person's life or materially jeopardize the covered person's health, DDWA shall expedite and process either a written or an oral appeal and issue a decision no later than seventy-two hours after receipt of the appeal. If the treating Licensed Professional determines that delay could jeopardize the eligible person's health or ability to regain maximum function, DDWA shall presume the need for expeditious review, including the need for an expeditious determination in any independent review consistent with applicable regulation. 2024-01-03100-BB 37 DCL 20240101
