Introduction

Dental procedure codes are integral to a smooth billing and coding process in dental practices. Among these, codes D0120 and D1110 play crucial roles. Understanding these codes and the latest updates is essential for dental office teams, ensuring compliance and accuracy in submissions. This guide delves into the intricacies of D0120 and D1110, offering workflow strategies and best practices for 2026.

Understanding D0120 and D1110

What Are D0120 and D1110?

  • D0120 refers to the periodic oral evaluation, an essential part of preventive oral care, providing a general assessment of the state of a patient’s oral health.

  • D1110 pertains to prophylaxis for adults. It includes cleaning procedures for adults to help maintain oral health and prevent disease.

Both codes are pivotal for insurance billing, requiring thorough documentation and correct usage for reimbursement.

Why Are These Codes Important?

Accurate use of D0120 and D1110 ensures timely reimbursements and minimizes the risk of claim denials. With ongoing updates in CDT codes, dental professionals must remain informed about any changes to maintain high standards of billing accuracy and compliance.
