Key Features of Dental Codes:
- Five-digit format (e.g., D0140 for limited oral evaluation)
- Updated annually to reflect new procedures and technologies
- Used universally by insurers, Medicaid, and Medicare (where applicable)
3. Importance of Dental Coding in Practice
Accurate coding is critical for:
✅ Insurance Reimbursement – Ensures claims are processed without delays.
✅ Legal Compliance – Prevents fraud and billing inaccuracies.
