Tips for Success in Dental Billing and Coding
Ready to learn how to prevent dental insurance verification errors and delays in billing? These tried-and-true tips can make your practice succeed more often with claims and minimise administrative stress:
Keep Current with CDT Code Updates
The ADA updates Current Dental Terminology codes each year. Applying old dental billing codes may result in claim denials, so keep your coding systems updated.
Preverify Patient Eligibility
Always confirm dental insurance before the patient visit to prevent denied claims for inactive policies or uncovered treatments.
Utilise Proper CDT Codes and Documentation
Coordinate procedures with the right dental codes for procedures and attach clear clinical notes to back up each submitted claim.
Train Your Staff Periodically
Ongoing training helps your staff be conversant with coding news, insurance policy updates, and the need to use the right dental procedure codes.
Collaborate with a Trustworthy Billing Specialist
Having a professional dental insurance verification company like QuestSol makes the process easier. We provide skilled health insurance verification, precise claim submissions, and diligent dental credentialing professionals, so you can concentrate on patient care while we manage the backend.
Why Should Your Practice Be Current with CDT Codes?
Staying current with Current Dental Terminology (CDT) codes is important because:
Accurate Insurance Billing
Incorrect codes lead to claim denial, underpayment, or delayed payment. The American Dental Association (ADA) changes codes every year to include procedures, technology, and coding guidelines.
Prevention of Insurance Errors
Misuse of expired or incorrect dental billing codes is a common reason for claim denials. Staying current eliminates dental insurance verification mistakes and reduces resubmission hassles.
Staying in Compliance
HIPAA, insurance plan, and legal documentation rules compliance is ensured through proper coding.
QuestSol keeps your practice up to code and streamlined by means of real-time surveillance and specialist assistance in dental insurance verification and putting into practice the latest codes for dental treatments.
