What Is CDT Coding and Why It Matter

Ever wondered what CDT coding is? It’s the backbone of dental billing, standing for Current Dental Terminology, a set of codes maintained by the ADA for standardizing procedures.

Understanding CDT (Current Dental Terminology)

CDT dental meaning boils down to a universal language for insurers. Unlike medical codes, these are dental-specific, ensuring clear communication.

CDT Codes and Descriptions (Printable 2025 Sheet)

Need a quick reference? A CDT codes and descriptions PDF or dental coding reference sheet is your go-to dental billing cheat sheet.

How to Read CDT Codes

  • Preventive: D1110 (prophylaxis)
  • Restorative: D2330 (resin filling)

Dental Hygiene and Ortho Codes Cheat Sheet

Importance of CDT Codes in Dental Insurance Billing

  • Health plans and dental insurers rely on the correct CDT code to adjudicate claims. If the wrong code is submitted, the claim may be denied, delayed, or underpaid.
  • Using the correct code helps ensure compliance with HIPAA and avoids potential audits or penalties.

Step-by-Step Dental Billing Guidelines 

Here is the 5-step follow-up plan followed by a dental insurance biller to process the medical dental billing.

Step 1: Patient Registration and Insurance Verification

  • When a patient arrives, gather their details accurately. This includes demographics, insurance information, and any medical history that might tie into medical dental billing.
  • Use an insurance verification cheat sheet to double-check coverage—does their plan cover dental office visit code like D0150 for comprehensive exams? Skipping this can lead to denials later.

Step 2: Procedure Documentation and Code Entry

Here’s where ADA dental coding shines.

  • Document every service with the right CDT coding guide. For instance, a simple filling might use D2391 for a one-surface resin composite.
  • Accuracy here prevents underbilling or overbilling.
  • Always follow the HIPAA rules to protect patient data
  • For medical-related dental billing, cross-reference CDT with CPT/ICD codes.

Step 3: Claim Submission to Insurance

  • Submit claims electronically for faster processing
  • Use dental billing guidelines to ensure forms like the ADA claim are complete.

Tip: Batch submissions weekly to keep cash flowing

Step 4: Payment Posting and Denial Management

  • Post payments to patient accounts promptly
  • Track discrepancies and appeal denials.

Tip: Denial management is crucial; missing codes cause 40% of claim denials.

Step 5: Reporting and Record Keeping

  • Generate reports on receivables and compliance.
  • Accounts receivable tracking spots aging claims. Retain records per HIPAA compliance rules—at least six years.
