Plan clauses to check during verification

Missing tooth clause

Whether a missing tooth clause applies depends on the group plan. Ask whether the plan excludes replacing teeth lost before coverage began, and note the answer before you present a bridge or implant. See how to spot the missing tooth clause.

Waiting periods

State of Wisconsin employee PPO Select plan: no waiting period for eligible new employees; late enrollees wait until the next open enrollment.

Downgrades (alternate benefit)

State of Wisconsin employee PPO Select plan: Delta Dental pays the maximum plan allowance for the least expensive adequate procedure; the patient owes the rest, or the full fee if not covered.

Frequency limits

Frequency limits vary by plan. Confirm cleanings, exams, bitewings, full-mouth X-rays and fluoride limits, and the date of the last service billed.

Verification checklist for Delta Dental of Wisconsin

• Confirm whether the patient has PPO, Premier or DeltaCare USA (DHMO) before treatment; fee schedules and rules differ by network.
• Use the secure dentist portal for eligibility, claim status and statements; the direct deposit form is only available there.
• The 15-month filing and 180-day appeal figures apply to the State of Wisconsin employee plan; other group contracts may differ.
• ERAs are shared through a national DentalXChange repository; check which clearinghouse the office already uses before re-enrolling.
• For DeltaCare USA (DHMO) patients, confirm the primary care dentist assignment before treating.
• Record the representative's name, the call reference number and the date for every phone verification.
