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.
