Dental Billing 101: What Every New Administrative Assistant Should Know

Stepping into the dental administrative industry is both rewarding and challenging, but it comes with a learning curve, particularly in billing tasks. 

Understanding the basics of dental billing is essential for your long-term success as a dental administrative assistant. Your primary role is to keep the office running efficiently by handling insurance claims and effectively managing patient accounts.

In this 2025 guide, we’ll cover the basic knowledge that every new dental administrative assistant needs, from standard billing codes to insurance terminology.

What is dental billing, and why does it matter?

Dental billing is the act of filing and pursuing payments with dental insurance providers so that the dental practice is paid for services rendered.

It entails interpreting the dentist’s care in standard, numeric codes, filing those codes with insurance companies, and collecting correct payment from the insurance carrier or the patient.

Dental billing is an essential aspect of a dental practice’s finances. 

Accurate billing pays the office promptly, ensures good patient relationships, and avoids costly errors and delays. In a dental administrative assistant, billing knowledge benefits the staff and keeps the practice profitable and efficient.

Understanding Common Dental Codes

Each dental procedure has a unique number known as a procedure code. The codes specify to the insurance company what procedure was performed, such as a cleaning, filling, or X-ray.

You don’t have to memorize each code, but you do have to know where to look them up in the system and assign the appropriate code to the dentist’s treatment. If you enter the incorrect code, payment may take longer or result in a claim denial.

Difference Between Medical and Dental Billing

Although dental and medical billing both involve processing insurance claims, there are some key differences:

Dental Billing:

• Uses CDT codes
• Focuses on oral health (teeth, gums, jaw)
• Annual benefit limits

Medical Billing:

• Uses ICD and CPT codes
• Covers a broader range of health issues
• Includes deductibles, coinsurance, and out-of-pocket maximums
  

Understanding the Difference Between Patient Payments and Insurance

To understand dental billing, one has to identify who pays for what aspect of a dental bill: the patient or the insurance provider. Both undertake a specific role in the billing process.

Insurance Payments

Dental insurance pays for the services based on a patient’s plan. After a dental procedure, a claim is put into the patient’s insurance carrier. The insurance provider reviews the claim and pays for services according to the patient’s coverage, which can be:

• Preventive care
• Basic procedures
• Major procedures

Patient Payments

Patients may be required to pay for:

• Copays
• Deductibles
• Coinsurance
• Non-covered services

Some patients pay upfront, while others are billed after insurance processes the claim. Clear communication about these responsibilities helps avoid confusion or frustration later on.

Keep Patient Information Safe and in Order

Dental clinics use personal information daily—names, addresses, insurance, and health information so you must keep everything confidential and protected.

You’ll also have to be precise when placing information into the system. Minor errors can cause charges to go out incorrectly or create patient confusion. Being detail-oriented and double-checking the work greatly helps in this profession.

Conclusion

Dental billing can be challenging for beginners, but with the right program and learning the right software to aid with daily administrative tasks, it’s a skill you can master that is also highly sought after in any dental practice.
