Timely filing limits

Delta Dental of Ohio does not publish one filing deadline for every plan on its provider pages. The limit depends on the employer group or plan, so confirm it on the patient's plan documents or with provider services before you rely on it. Our guide to timely filing limits covers the common ranges.

EFT and ERA enrollment

Log in to the Dental Office Toolkit and follow the direct deposit link; new users register first. Activation typically takes seven days. EFT/ERA opt-in applies nationally across all Delta Dental member companies at once, not company by company.

Credentialing and network enrollment

Contact: https://www.providerwebportal.com/pact-ui/login

Self-service Provider Application and Credentialing Toolkit (PACT). Delta Dental of Michigan, Ohio and Indiana is NCQA-accredited for credentialing as one entity. No credentialing phone is published.

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

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