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)
Ask whether posterior composites are paid at the amalgam rate and whether crowns downgrade to a base-metal benefit, so the patient estimate is right the first time.
Frequency limits
Delta Dental Smiles (Medicaid): denture and partial repairs once per 3 years; complete maxillary denture relines once per 3 years, starting one year after delivery.
Verification checklist for Delta Dental of Arkansas
- Confirm which network covers the patient (Premier, Premier/PPO, Smiles Medicaid or Allwell Medicare Advantage); each has its own mailing address and rules.
- Use the Dental Office Toolkit at deltadentalsmiles.com for real-time Smiles claim status rather than mailing paper claims.
- Do not mail a paper claim after filing electronically; duplicates delay processing.
- Commercial timely filing and appeal deadlines are not published; confirm with Professional Relations before relying on a day count.
- PO Box 6247 (ZIP 72124) is printed as Little Rock on one page and Sherwood on another; confirm with Professional Relations if mail is returned.
- Record the representative's name, the call reference number and the date for every phone verification.
