The Ultimate List Of Dental Billing Codes 2024

Every healthcare department has its distinct set of codes. These codes serve as a base to file claims, create bills, and receive payment. Specifically dentists, too have different codes for their facility. However, having a list of dental billing codes is essential as there are hundreds of them, and can’t be learned. So a list can help find accurate codes according to the certain dental conditions.

So here we are providing an ultimate list of codes used in dental practice. Stay tuned as we dive into the coding world of this healthcare department.

Understanding Codes Used in Dental Billing

Dental billing codes are no different than other coding systems. But for beginners, let’s have an overview of what types of codes are utilized during dental coding and billing.

Current Dental Terminology (CDT)

Just like CPTs are created by the AMA, CDT codes are specifically designed for dental billing by the American Dental Association (ADA). 

These codes are utilized to list dental services and procedures and send to patient’s respective insurers.

Healthcare Common Procedure Coding System (HCPCS)

Among dental billing codes, HCPCS level II is mostly used by coders. Basically, these are the codes that are not included in the CPT code category.

Internal Classification of Diseases (ICD)

Dental ICD codes help in reporting diagnoses and medical conditions. These codes are used to describe patient’s diagnoses or the reason for patient visits. 

These are crucial codes that provide necessary information for insurance claims.

Current Procedural Terminology (CPT)

Although CPT codes are not very used in dental billing codes. 

But they can occasionally be mentioned if the patient has medical insurance instead of dental insurance and must be treated soon.
