Credentialing and network enrollment

Contact: Network Services 1-800-890-4774 (fax 509-468-6550)

Dentists are credentialed individually. Requirements include a valid license and DEA certificate, accredited dental degree, specialty verification if applicable, malpractice insurance and claim history, 5 years of work history and attestations. The Dentist Agreement auto-renews every 12 months.

Plan clauses to check during verification

Missing tooth clause

Guardian will not pay for a prosthetic replacing teeth missing before coverage unless it also replaces a tooth lost while insured. Does not apply to existing restorations.

Waiting periods

Some plans include waiting periods by service category; benefits vary by member.

Downgrades (alternate benefit)

Least Expensive Alternate Treatment may apply. Contracted dentists may bill the patient up to the fee schedule amount for the costlier service performed.

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 Guardian Dental

• Search benefits in Guardian Anytime by name, DOB and relationship or member ID; it shows CDT-level coverage and last-visit history for up to 8 patients.

• For clinical review, send dated, labeled diagnostic radiographs (FMX preferred for SRP) and chart notes; panoramic films alone are of limited diagnostic value.

• Confirm the network: DentalGuard Select is administered by a TPA, so use the number on the member's ID card, not Guardian's lines.

• File claims within 15 months of the date of service, per Guardian's claim-filing guidance.

• For First Commonwealth, Managed DentalCare or Managed DentalGuard patients, call the plan-specific call center, not the Group Benefit Service line.

• Guardian pays by virtual credit card via ECHO Health unless you register for EFT or check.

• Record the representative's name, the call reference number and the date for every phone verification.
