D4266 Dental Code
D4266 Dental Code Definition
D4266 dental code definition is the dental procedure for Guided tissue regeneration – resorbable barrier, per site.
The D4266 dental code is officially defined in the Current Dental Terminology (CDT) system as the dental procedure for Guided Tissue Regeneration – resorbable barrier, per site. This CDT code is used to describe a specialized periodontal treatment that involves placing a resorbable barrier membrane in a surgical site to promote the selective growth of desired tissues. By preventing unwanted soft tissue from interfering with bone and ligament healing, guided tissue regeneration enhances periodontal regeneration, supports long-term tooth stability, and improves overall treatment outcomes.
When submitting dental procedure billing with the D4266 code, it is essential for dental professionals to verify that this CDT code accurately reflects the service performed. Since CDT codes are highly specific, the correct selection of D4266 ensures that dental insurance companies process the claim accurately and that patients receive proper reimbursement for the periodontal treatment provided. Misuse of CDT codes can lead to claim denials, delays in payment, or incorrect patient billing, which makes careful code selection a critical part of dental practice management.
Dental providers are also encouraged to review whether there may be alternative CDT codes that better describe the procedure, depending on the exact clinical situation. For example, other guided tissue regeneration codes may apply if a non-resorbable barrier is used, or if additional surgical procedures are performed at the same site. By carefully cross-checking CDT options, practitioners can ensure that the billing process is both compliant and precise, reflecting the treatment performed with accuracy.
The D4266 CDT code highlights the importance of staying updated with ADA’s annual revisions to the dental coding system. Since CDT codes are updated every year, dentists and billing staff should always confirm that the D4266 code remains valid and has not been modified or replaced. Proper usage of D4266 not only improves claim success but also helps maintain accurate dental records that reflect best practices in periodontal care.
What is D4266 Dental Code?
The D4266 dental code is a CDT (Current Dental Terminology) billing code used to describe the periodontal procedure known as Guided Tissue Regeneration – resorbable barrier, per site. This treatment is designed to encourage the natural regrowth of bone and supporting tissues around teeth affected by periodontal disease. By placing a resorbable barrier membrane at the surgical site, the dentist prevents unwanted soft tissue from growing into the area, allowing bone and ligament tissue to regenerate properly.
When a dental professional bills with the D4266 CDT code, it signifies that a guided tissue regeneration procedure was performed using a resorbable barrier, and that the billing applies per individual surgical site treated. This CDT code is important for insurance claim processing because it ensures that the treatment is documented clearly, with a distinction between resorbable and non-resorbable barriers. Accurate coding with D4266 helps avoid claim denials, supports proper reimbursement, and keeps patient treatment records in compliance with ADA standards.
The D4266 dental code also highlights the importance of correct code selection in dental billing. Using the wrong CDT code can lead to rejected claims or incorrect patient charges, which is why dental offices must confirm that D4266 is the best match for the procedure performed. Since CDT codes are updated annually by the American Dental Association, dentists and billing teams should always make sure they are referencing the latest CDT manual to confirm that D4266 is still valid and has not been revised. Proper application of the D4266 dental code helps streamline the billing process, ensures transparency in dental records, and contributes to the overall efficiency of dental practice management.
Understanding D4266 Dental Code, Dental Coding and Billing
The D4266 dental code is an important part of the CDT (Current Dental Terminology) system, which is published annually by the American Dental Association (ADA) and used universally for dental procedure documentation, billing, and insurance claims. Specifically, D4266 represents Guided Tissue Regeneration – resorbable barrier, per site. This periodontal treatment involves the placement of a resorbable membrane at the surgical site to promote proper healing and regeneration of bone and supporting tissues while preventing unwanted soft tissue from interfering with recovery.
For dentists and dental billing professionals, understanding how to correctly apply the D4266 CDT code is essential. Accurate dental coding ensures that claims submitted to insurance providers are processed correctly, reduces the risk of denials, and guarantees proper reimbursement for services provided. For patients, correct use of D4266 in billing helps clarify the exact procedure performed and prevents unnecessary delays or misunderstandings with dental insurance coverage.
Dental coding and billing can be complex, especially when dealing with specialized procedures such as guided tissue regeneration. By learning more about D4266 and how it fits within the broader CDT coding system, both providers and patients can gain confidence in the accuracy of dental records, insurance submissions, and financial transparency.

What are CPT Codes?
CDT codes, officially known as Current Dental Terminology, are the standardized dental procedure codes published and updated each year by the American Dental Association (ADA). These codes serve as the universal reference manual for dental treatments, procedures, and nomenclature. Dentists, hygienists, office administrators, and dental insurance companies all rely on CDT codes to ensure consistency in patient records, accuracy in claim submissions, and clarity in billing practices. Without CDT codes, dental billing would lack structure, leading to miscommunication, rejected claims, and confusion across the dental industry.
Each CDT code represents a specific dental procedure. For example, the D4266 Dental Code is the official billing code for Guided Tissue Regeneration – resorbable barrier, per site. This code is widely used in periodontal treatments to document procedures where a resorbable barrier membrane is placed to encourage the regrowth of bone and supporting structures while preventing unwanted soft tissue from interfering. By applying the correct CDT code, such as D4266, dental professionals not only follow ADA coding standards but also ensure that their patients’ insurance claims are processed quickly and accurately.
