2. Understanding Dental Codes (CDT Codes)

What Are CDT Codes?

The Current Dental Terminology (CDT) is a standardized coding system maintained by the American Dental Association (ADA). These codes are used to describe dental procedures for billing and insurance purposes.

Why Are CDT Codes Important?

• Standardization: Ensures uniformity in dental billing.

• Insurance Claims: Required by Blue Cross and other insurers for reimbursement.

• Tracking & Analytics: Helps in tracking treatment trends and insurance approvals.

CDT Code Structure

Each CDT code consists of:

• A letter (D) followed by four digits (e.g., D0120 for periodic oral evaluation).

• Updated annually to reflect new procedures and technologies.

3. Why Dental Codes Matter for Blue Cross Insurance

Blue Cross Blue Shield, like other insurers, relies on CDT codes to:

• Determine Coverage: Some procedures are only covered if billed with the correct code.

• Prevent Claim Denials: Incorrect codes lead to rejected claims.

• Set Reimbursement Rates: Each code has an assigned fee schedule.
