Dental credentialing services →Send group dental claims electronically with payer ID CX087, the ID on Mutual of Omaha's own dental provider flyer. Some clearinghouse payer lists carry 71412 for Mutual of Omaha dental instead, so check your clearinghouse list before your first claim and keep whichever it accepts. Paper claims go to Mutual of Omaha, Claims, P.O. Box 211472, Eagan, MN 55121.
File under the insured member's number from the ID card. Mutual of Omaha's flyer says claims are filed using the insured member number, so a claim keyed to a dependent's details alone can stall.
Indemnity plans work differently. Mutual of Omaha tells group indemnity members to bring a claim form to the dentist at their first visit. Its claim form is on mutualofomaha.com.
Group dental is underwritten by United of Omaha Life Insurance Company or Mutual of Omaha Insurance Company. Individual dental is underwritten by Mutual of Omaha Insurance Company and, by its own description, administered at least in part by TruAssure Insurance Company. Mutual of Omaha does not publish a separate claims address for individual plans, so use the address and phone number on the patient's card, or call individual dental support at 800-775-1000.
Both lines use the DenteMax Plus network. For group plans it is branded the Mutually Preferred Network powered by DenteMax Plus. If you are in DenteMax, the DenteMax fee schedule applies.
For out-of-network dentists, Mutual of Omaha's group dental FAQ says that in most cases it sends reimbursement directly to the member. If the patient has not paid at the visit, collect at the time of service or have a signed assignment ready, and expect the check to go to the patient anyway in many cases.
Written appeals go to Mutual of Omaha, Attn: Appeals and Grievances, P.O. Box 211472, Eagan, MN 55121. Mutual of Omaha does not publish a deadline, so appeal as soon as the denial arrives. See our dental appeals guide.
A pretreatment estimate is not required, but the group FAQ recommends one for non-emergency treatment of $300 or more. That is the cheapest way to catch a frequency limit, a waiting period or a missing tooth clause before the patient is in the chair.
