D0274 Dental Code
D0274 Dental Code is the dental procedure for Bitewings – Four Radiographic Images – Limit To 1 Series Every 6 Months.
The D0274 Dental Code refers to the dental procedure involving four bitewing radiographic images, a diagnostic tool commonly used by dental professionals to detect cavities (dental caries), monitor bone loss, and evaluate the alignment and spacing between teeth. This code is part of the Current Dental Terminology (CDT) code set maintained by the American Dental Association (ADA) and is widely used in dental practices for billing and clinical documentation purposes.
The D0274 CDT code is specifically used when four separate bitewing X-ray images are taken during a single visit. These images capture both the upper and lower posterior teeth on both sides of the mouth. This comprehensive series helps dentists detect issues between the teeth that may not be visible during a standard visual examination. Bitewing X-rays are essential for diagnosing interproximal decay, early gum disease, and changes in bone structure.
It is important to note that most dental insurance plans allow reimbursement for D0274 only once every six months, unless additional radiographs are deemed medically necessary and properly documented. Dental offices must adhere to these insurance limitations and submit supporting clinical justification if bitewings are taken more frequently.
Accurate CDT code selection not only ensures compliance with dental billing standards but also reduces the risk of claim denials and supports faster insurance reimbursement. Dentists and billing coordinators should reference the latest ADA CDT coding manual or consult with an experienced dental coder when in doubt.
D0274 is the standard CDT code used for a complete series of four bitewing radiographs. It is one of the most commonly utilized diagnostic codes in preventive dental care and is essential for ongoing oral health monitoring. To achieve proper billing accuracy and avoid insurance complications, always verify the procedure performed and review related CDT codes for the best match.
D0274 Dental Code Definition
What is D0274 Dental Code?
The D0274 dental code is a specific CDT (Current Dental Terminology) code used to describe a common diagnostic dental procedure involving four bitewing radiographic images. This procedure is essential for identifying dental issues such as interproximal decay, bone loss, tooth alignment issues, and other conditions that may not be visible during a standard clinical examination. These four images provide a comprehensive view of both the upper and lower posterior teeth on each side of the mouth.
According to most dental insurance guidelines, the D0274 CDT code is typically limited to one series every six months as part of a routine dental check-up. Bitewing X-rays are considered a preventive service and are vital in helping dental professionals detect problems early, which supports effective treatment planning and long-term oral health.
D0274 is one of the most frequently used radiographic codes in dental billing and is recognized and accepted by all major dental insurance carriers. But it is also important to understand the context and limitations of the D0274 dental code when preparing dental insurance claims. The D0274 dental code represents the procedure for taking a full set of four bitewing radiographs and is a key component of preventive dental care. Accurate usage of this code allows for proper documentation, precise billing, and timely insurance reimbursement. It also helps ensure that patients receive the best diagnostic care based on their specific oral health needs.
D0274 Dental Code & CDT Codes Explained
What are CDT Codes (Current Dental Terminology)?
The D0274 Dental Code, which refers to the dental procedure for taking four bitewing radiographic images, is just one example of the thousands of standardized codes included in the Current Dental Terminology (CDT) coding system. Maintained and published annually by the American Dental Association (ADA), CDT codes are the official language used across the dental industry for documenting and billing dental services accurately.
CDT codes like D0274 are essential tools used by dentists, oral health professionals, insurance companies, and billing coordinators to ensure uniformity and transparency in the communication of dental procedures. These codes are recognized nationwide by all major dental insurance carriers, enabling providers to submit claims efficiently and receive timely reimbursement for the services they perform.
The CDT coding system is updated each year to reflect the latest developments in dental treatments, technologies, and regulatory requirements. These updates include revisions to existing CDT codes, the introduction of new dental procedure codes, the removal of obsolete codes, and clarification edits from the ADA. Staying current with these changes is critical for compliance and financial accuracy in any dental practice.
For example, D0274 is used when a dentist captures a complete series of four bitewing X-rays—a diagnostic procedure typically performed once every six months during routine dental checkups. Understanding when to use D0274 instead of related codes such as D0272 (two bitewing images) or D0273 (three bitewing images) is essential for correct coding and billing.
Learning how CDT codes work and how they are interpreted by dental carriers, benefit administrators, and third-party payers can help prevent insurance claim denials, improve patient communication, and streamline office workflows. Dental professionals are encouraged to refer to the official ADA CDT codebook and stay updated with annual changes to maintain accurate and compliant dental billing practices.

CDT codes are integral to setting coverage policies, streamlining audits, and verifying clinical necessity.
Health information technology systems—including electronic health record (EHR) platforms, dental practice management software, and insurance billing platforms—are built around the CDT coding structure.
