D4210Gingivectomy or Gingivoplasty - Four or More Contiguous Teeth or Tooth Bounded Spaces Per Quadrant

What This Code Covers

D4210 covers the surgical removal (gingivectomy) or reshaping (gingivoplasty) of gum tissue involving four or more contiguous teeth or tooth-bounded spaces in a single quadrant. This procedure is performed to eliminate diseased gum pockets, correct gum overgrowth (hyperplasia), or reshape the gingival contour for better oral hygiene access and periodontal health.

Billing Guide

Bill this code when:

• Gingivectomy or gingivoplasty is performed on four or more contiguous teeth in one quadrant
• The procedure addresses gum disease (pocket reduction) or gum overgrowth
• Tissue is surgically removed or reshaped to improve gingival health or contour
• The indication is periodontal, not cosmetic crown lengthening

Do not bill this code when:

• Fewer than four contiguous teeth are treated. Use D4211 for one to three teeth
• Osseous (bone) surgery is also performed. Use D4260 or D4261
• The procedure is crown lengthening for restorative purposes. Use D4249
• Laser gingivectomy is performed as an adjunct to scaling (may be considered part of D4341/D4342)

Insurance and Denial Prevention

Key Payer Rules:

• D4210 is a per-quadrant code for four or more contiguous teeth
• Most payers require periodontal charting documenting the condition being treated
• Some plans classify gingivectomy as a major periodontal benefit with higher cost-sharing
• Drug-induced gingival overgrowth (from medications like phenytoin or nifedipine) is a common covered indication

Common Denials and How to Respond:

• Not medically necessary - Submit periodontal charting showing pseudopockets from tissue overgrowth or persistent pockets that have not responded to scaling and root planing.
• Should be D4211 - Verify the number of contiguous teeth treated. D4210 requires four or more; D4211 is for one to three.
• Cosmetic procedure - Document the medical or periodontal necessity. Include the diagnosis (gingival hyperplasia, periodontal disease) rather than esthetic concerns.
