Preventive Care and Oral Hygiene: What Dental Billing Specialists Should Know
Published by the American Dental Coders Association
As a dental billing specialist, understanding clinical terminology is only part of the job — knowing how preventive care and oral hygiene translate into billing accuracy and patient outcomes is essential. Preventive dentistry is the cornerstone of oral health, and many of the services performed in a dental office fall under this category.
This blog post breaks down what preventive care means in dentistry, how it impacts billing workflows, and why it matters in your day-to-day role as a billing specialist.
What Is Preventive Dental Care?
Preventive dental care refers to treatments and services that help maintain oral health and prevent the onset of dental disease. These procedures are typically performed during routine visits and include everything from cleanings to fluoride applications.
Common Preventive Services Include:
- Oral exams (periodic, comprehensive, limited)
- Prophylaxis (cleanings)
- Fluoride treatments
- Sealants
- X-rays (bitewing, panoramic, periapical)
- Oral hygiene instruction
Why Preventive Care Matters in Dental Billing
Insurance companies often fully or partially cover preventive procedures, and patients may not understand the difference between what’s covered at 100% and what applies to their deductible or co-pay.
As a billing specialist, it’s your job to:
- Accurately code and bill these services
- Ensure that frequency limits are not exceeded
- Confirm patient eligibility and plan allowances
- Educate the team on payer rules for routine exams and cleanings
When preventive services are misbilled or overutilized, claims may be denied — delaying reimbursement and increasing patient frustration.

- Documentation requirements: Sealants and fluoride may require clinical notes.
- COB confusion: Primary vs. secondary plan mix-ups can delay payment.
