Providers:

Check out our monthly must-read designed to help you stay informed, save time and focus on patient care.

Reminder: Urgent prior authorization requests

To ensure timely and appropriate review of prior authorization and other review requests, requests submitted as urgent or expedited must meet the CMS definition of an expedited request and be supported by clinical documentation demonstrating the urgent need. 

CMS defines an expedited/urgent request as: 

“A request for a determination in which waiting for a decision under the standard timeframe could place the member's life, health, or ability to regain maximum function in serious jeopardy.

Providers are encouraged to carefully assess the clinical circumstances and submit all relevant supporting documentation at the initial submission to avoid delays in processing.

Dental Office Toolkit™ (DOT) enhancements

Several enhancements have been made to improve the claims experience in DOT, including expanded claim views for members and families, improved search and filtering options, claim export to CSV and enhanced treatment detail visibility through expandable claim information.

Additional updates, such as sortable columns and streamlined action buttons, make it easier to find, review and manage claims.

Cracking the code: D4249 (crown lengthening) vs. D4212 (gingivectomy for restorative purposes)

D4212

D4212 is appropriate when only soft tissue is removed to gain access for a restoration.

D4249

D4249 should be reported only when the procedure includes flap reflection, osseous resection and exposure of additional tooth structure through hard-tissue removal. Documentation for D4249 should clearly support bone removal and the restorative need for crown lengthening.

Quick tip:

If no bone is removed, D4212 is generally the appropriate code. If bone removal is required to expose additional tooth structure for restoration, consider D4249.

Medicare Advantage requirement: Type 2 National Provider Identifier

Providers submitting claims for Medicare Advantage members must have a Type 2 National Provider Identifier (NPI) on file for their business. Federal law requires all healthcare providers and organizations use a standard identifier in their administrative and financial transactions.
All electronic claims submitted to Delta Dental must include:

  • Treating dentist’s Type 1 NPI 
  • Treating dentist’s state license number 
  • Tax Identification Number (TIN) of the billing dentist or practice 
  • Type 2 NPI to identify the billing provider, following these guidelines:
    • Multiple dentists at one practice location (group practice, partnership): Type 1 for each dentist and Type 2 for the practice, if claims are transmitted in the practice’s name and TIN.
    • Multiple dentists at multiple practices (clinics, dental service organizations, etc.): Type 1 for each dentist and Type 2 for each practice, with a separate TIN.
