Some CDT Codes, especially recent additions, may not be readily understood by dentists and others in the dental community. These codes prompt a need for a coordinated educational message on the procedure and its reporting. The American Dental Association, with support from organizations on the Code Maintenance Committee and others in the dental community, has developed a variety of educational material. This information, within the following list of topics, is available online for anyone to download, read or view.
Bitewings and Extraoral Image Procedure Codes – Watch Video
This short video, available at no cost for you to watch, covers a number of topics that will help dentists properly prepare and submit a claim form. Services are listed below.
- Overview of dental claim form
- Recording procedure information on a service line
- Diagnostic codes on a dental claims
- ADA resources to help you submit claim
Getting Paid: Coding on a Claim Form – Watch Video – Watch Video
The recording will address the evolving tools, techniques and scenarios for image capture and interpretation, as well as provide specific answers to questions that may have come to mind such as:
- Am I reporting bitewings correctly when capturing the image extra-orally?
- In a teledentistry encounter, how are image capture and interpretation procedures documented?
Featuring speakers Dr. Walter Weber (Chair, Dental Benefit Information Subcommittee at ADA Council on Dental Benefit Programs) and Dr. Jessica Stilley (Member, ADA Council on Dental Benefit Programs).

This program is a primer that covers a number of services and their CDT Codes that establish and support prevention and ongoing oral health. There is more – an overview of emerging interest in dental diagnosis coding, CDT Code maintenance, and where coding and claim submission assistance is available from the ADA. The material covered is pertinent to activities and services delivered by private dental practices, as well as Medicaid MCOs and Federally Qualified Health Centers (FACHs).
The program’s Part 1 begins with commentary on some things that are relatively old – several pertinent diagnostic, preventive and administrative procedures that have been part of the CDT Code for several editions. Part 2 discusses case management – ways to bring patients into your operatories so that they receive necessary dental care, and the four new CDT Codes to document these efforts. In Part 3 the program closes by addressing some ins-and-outs and how-to’s concerning codes used every day within the dental community.

During its March 2022 meeting the ADA’s Code Maintenance Committee (CMC) approved seven (7) new COVID-19 vaccination procedure codes. These codes are now part of CDT 2022.
A memorandum to the entire dental community that announces the inclusion of these codes in CDT 2022, from the Council on Dental Benefit Programs and CMC Chairs, is available for reading and download.
This memorandum also announces an update to the ADA’s vaccination procedure coding guidance document, available online for reading and download.
These newly approved COVID vaccination procedure codes are also listed for anyone to download or view on the CDT Publication Errata web page as they are not included in the printed CDT 2022 manual.
This guide is published to educate dentists and others in the dental community on selection and reporting of diagnostic imaging procedures documented with codes listed in the Diagnostics category of service under “Image Capture Only.” CDT 2021 marks an expansion of codes in this sub-subcategory of service.
The “ADA Guide to ‘Image Capture Only’ Procedures and Their Reporting” is a comprehensive review and discussion of these procedures and their documentation. This publication includes a code selection decision tree and scenarios intended to provide insight and understanding of the procedures and their reporting.

This guidance document addresses confusion over appropriate documentation and reporting overdenture procedures as the applicable codes differ depending on the components and whether the prosthesis is borne by natural teeth or implants. The two scenarios illustrate coding for placement of maxillary and mandibular overdentures for a fully edentulous patient. This guidance also applies to placement of other types of overdentures (e.g., partial).
This guidance document addresses reporting extraction procedures, often referred to as “simple”, documented with CDT codes D7140, D7210 or D7250. Selection of the applicable code depends on the clinical scenario, several of which are described herein. Inquiries concerning these procedures led ADA staff to conclude that there is some confusion over CDT code selection. These recurring inquires indicated that there is a need to educate dentists and others in the dental community on appropriate procedure documentation.

Some CDT codes, especially recent additions, may not be readily understood by dentists and others in the dental community. In response, the ADA, with support from knowledge experts in the dental community, has developed a new CDT code guide. The aim is to help dentists understand the procedures underlying these codes and how they should be reported.

Some dentists have patients who, for any number of reasons, have communication challenges that can be addressed through the use of oral translators or visual sign language. A robust patient dental record would document when such a service is provided.
The ability to record use of such services is especially valuable for dentists who are covered entities under nondiscrimination laws such as the Affordable Care Act (ACA) Section 1557. Dentists who are subject to such laws may be required to provide “meaningful access to individuals with limited English proficiency" as well as providing effective communication with individuals with communications disabilities such as vision, hearing, or speech disabilities, often through the use of qualified interpreters and translators.
As of January 1, 2019 there is a specific CDT code to document and report interpreter and translator services –
D9990 certified translation or sign-language services – per visit
CDT code D9990, first published in CDT 2019, is intended to document these services in a clinical scenario when an individual and the doctor or practice staff do not share a common language and a translator or translation service is used to ensure meaningful communication, or when a qualified interpreter is used to ensure effective communication with an individual with a disability. Such assistance, subject to applicable regulatory or contractual requirements, is provided by qualified bilingual staff, staff interpreters, contracts or formal arrangements with organizations or individuals providing interpretation or translation services in-person or through technology and telephonic interpretation services.
NOTE: This guidance supersedes the prior recommendation that code “D9994 dental case management – patient education to improve oral health literacy” could be used to document translation services. CDT code D9990’s nomenclature is more explicit, therefore use of D9994 to document translation services is no longer correct.
Under nondiscrimination laws such as Affordable Care Act, Section 1557 regarding non-discrimination, there may be a requirement for covered entities to provide free language services to individuals with limited English proficiency, and effective communication with individuals with communications disabilities. CDT code D9994 remains available for use when deemed appropriate to document services as described in the code’s descriptor.
Although D9990 refers to “certified translation or sign-language services,” ADA recommends that it apply to qualified interpretation and translation services, whether or not the provider is certified and whether the service is considered interpretation or translation.
As always, it is up to the dentist to read the full nomenclature and descriptor of a CDT code entry to determine whether the code is appropriate to report the service provided. When the dentist determines that there is no applicable CDT code, an unspecified procedure, by report code may be used to document and report the service (e.g., D9999 unspecified adjunctive procedure, by report).
Please note that: 1) the existence of a CDT Code is not a guarantee of reimbursement for the service by a third-party payer; and 2) HIPAA only requires a third-party payer to accept a CDT Code that is valid on the date of service, and does not mandate coverage.
A “strip crown” is a direct procedure that involves: 1) placing a form on the tooth; 2) filling the form with composite resin that bonds directly to the tooth in the shape of a crown; 3) removal of the form from the tooth after the composite resin cures (i.e., the form is “stripped away” from the tooth and composite resin crown); and 4) finishing and final polishing as necessary.
The ADA’s position is that a “strip crown” procedure would be reported with a CDT Code listed within the “Resin-Based Composite Restorations — Direct” subcategory of service. Further, the dentist who delivers this procedure would consider the full CDT Code entry when determining the code that appropriately describes the service she or he delivered. Should a dentist be delivering a direct composite resin restoration, selection of the appropriate CDT Code is affected by the preparation —
If the restoration is full coverage with no visible original enamel, this is a crown procedure documented with the following CDT Code.
resin-based composite crown, anterior
Full resin-based composite coverage of tooth.
(Note: Should a dentist elect to deliver such a direct crown to a posterior tooth, the applicable CDT Code is “D2999 unspecified restorative procedure, by report.”)
If some of the original enamel is preserved on any of the surfaces, this is a multi-surface restoration procedure documented with one of the following CDT Codes.
resin-based composite — four or more surfaces or involving incisal angle (anterior)
Incisal angle to be defined as one of the angles formed by the junction of the incisal and the mesial or distal surface of an anterior tooth.
resin-based composite — four or more surfaces, posterior
There is no question that a “strip crown” procedure is a direct resin-based composite restoration procedure. All the clinical steps occur inside the patient’s mouth, which meets the ADA Glossary of Dental Clinical and Administrative Terms definition of direct restorations (“A restoration fabricated inside the mouth.”). The “strip” is simply a form that enables creation of the artificial crown in-situ.

In some parts of the dental community D1354 has been referred to as the SDF code, which is an understandable misperception as this medicament is widely used for the procedure. The code’s nomenclature and descriptor are intentionally more broadly worded and inclusive. Find out why in the guide. Inside you will also find out about this code’s CDT 2018 revision, adding “…– per tooth” to its nomenclature so that the procedure is reported consistently.

Patients with generally healthy periodontium receive preventive care, and those with periodontal disease involving bone and attachment loss receive therapeutic care. But what about patients who are in-between, who have widespread gingival inflammation but no bone or attachment loss? CDT Code D4346, added in CDT 2017, addresses this procedure that lies between a prophylaxis and a scaling and root planing. To learn about the procedure for these “in-between” patients and its code “D4346 scaling in presence of generalized moderate or severe gingival inflammation – full mouth, after oral evaluation”, download the publication, and view the webinar delivered in September 2016.
CDT code D4355’s nomenclature and descriptor were revised in CDT 2018 to emphasize that this is a preliminary procedure that sets the stage for a comprehensive oral evaluation on another day. But, many people ask, how is the need for the D4355 procedure determined and documented?
The publication “D4355 – ADA Guide to Reporting Full Mouth Debridement” answers this question, and more. It is available at no cost for you to view or download
The ADA’s position is that when coding for removal of impacted teeth the selection of either D7230 or D7240 is dependent on the definition of an “anatomical crown”. The full entries for these codes, as published in the CDT Manual, are: D7230 removal of impacted tooth – partially bony
Part of crown covered by bone; requires mucoperiosteal flap elevation and bone removal. D7240 removal of impacted tooth – completely bony
Most or all of crown covered by bone; requires mucoperiosteal flap elevation and bone removal.
anatomical crown: That portion of tooth normally covered by, and including, enamel.
Given this definition, the “crown” referenced in these codes’ descriptors is the portion of the tooth above the cemento-enamel junction. It follows that “part of the crown” should be interpreted as “less than 50% of the entire crown” and “most or all of the crown” should be interpreted as “at least or more than 50% of the entire crown”.
An interpretation that some portion of the occlusal surface must reside below the bone in order for D7240 to apply is an incorrect interpretation.
The dentist who removes an impacted tooth or teeth removal would consider this guidance and the full CDT Code entry when determining the code (D7230 or D7240) that appropriately describes the service she or he delivered.
D7230 and D7240 – Guidance on Coding for Impacted Teeth Removal Procedure as seen above is also available at no cost for you to download.
The ADA guide to reporting “D9912 Pre-Visit Patient Screening” addresses how this procedure aids determining whether there is a risk to practice staff if the patient is permitted entry, or if findings indicate that rescheduling the appointment is prudent.

Case management occurs when the techniques that enable early interventions and ensure needed dental services are delivered. To learn more about these procedures and how they are being used today, and about the four CDT Codes added in CDT 2017 to document their delivery, view the program delivered in August 2016.
CDT 2018 marks the addition of codes for documenting and reporting the two types of teledentistry scenarios a dentist can play a part in – one where data is collected and addressed in real-time, and the other where data is collected, stored and forwarded to be addressed at another time and location.
Teledentistry provides the means for a patient in one physical location to receive services, and the dentist or other oral health or general health care practitioner overseeing the delivery of those services is in another location. This mode of patient care makes use of telecommunication technologies to convey health information and facilitate the delivery of dental services without the physical constraints of a brick and mortar dental office.
