D4267Guided Tissue Regeneration - Nonresorbable Barrier, per Site (Includes Membrane Removal)

What This Code Covers

D4267 covers guided tissue regeneration - nonresorbable barrier, per site (includes membrane removal). A membrane barrier is placed to guide selective tissue growth into a periodontal defect. The code depends on whether the barrier is resorbable or non-resorbable.

Billing Guide

Bill this code when:

• The procedure described by D4267 is performed and documented
• The clinical indication supports the procedure
• Documentation meets the payer's requirements for the service

Do not bill this code when:

• A different procedure was actually performed
• The procedure is included in another code being billed at the same visit
• Documentation does not support the medical necessity of the procedure
• The procedure is better described by D4249 (Clinical crown lengthening - hard tissue)

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.
