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
Waiting periods are set by the group plan. Confirm the waiting period for basic and major services and the patient's effective date.
Downgrades (alternate benefit)
Handbook definition: the alternate benefit is the amount allowed for the least costly, most commonly accepted service when a covered person selects a more costly treatment.
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 Colorado
Submit predeterminations for basic and major services before treatment; the handbook recommends it, and predeterminations stay valid for 90 days.
Check claim status in the Provider Portal before resubmitting; duplicate paper claims delay processing.
Send corrected claims with documentation to appeals@ddpco.com, not to the claims mailing address; a new claim form there is treated as a duplicate.
Written appeals are due within 180 days for commercial plans, but within 60 days for Medicare Advantage reconsiderations.
Confirm the plan type (PPO or Premier, Medicare Advantage, or Connect for Health Colorado exchange); routing differs by plan.
Record the representative's name, the call reference number and the date for every phone verification.
