D4285Non-autogenous Connective Tissue Graft Procedure (Including Recipient Surgical Site and Target Material) - Each Additional Contiguous Tooth, Implant or Edentulous Tooth Position in Same Graft Site

What This Code Covers

D4285 covers non-autogenous connective tissue graft procedure (including recipient surgical site and target material) - each additional contiguous tooth, implant or edentulous tooth position in same graft site. Soft tissue is harvested from a donor site (or a non-autogenous material is used) and placed at the recipient site to increase tissue volume or cover exposed root surfaces. Both the donor and recipient surgical sites are included in this code.

Billing Guide

Bill this code when:

• The graft procedure described by D4285 is performed
• The graft material type and site match the code description

Do not bill this code when:

• The graft type or material does not match this code
• The graft is included in another surgical code being billed at the same visit
• No actual graft material was placed
• The procedure is better described by D4265 (Biologic materials to aid in soft and osseous tiss...)

Insurance and Denial Prevention

Key Payer Rules:

• Periodontal treatment is typically covered as a major service (50-80%)
• Full-mouth debridement (D4355) and D4346 may have specific frequency limits
• Surgical periodontal procedures often require documentation of previous non-surgical treatment
• Some plans require periodontal charting with probing depths for approval

Common Denials and How to Respond:

• Insufficient documentation - Submit complete periodontal charting, radiographs, and a narrative of findings.
• Non-surgical treatment not attempted first - Document previous scaling/root planing and explain why surgery is now indicated.
• Frequency exceeded - Verify the payer's frequency schedule for the specific procedure.
