Current Dental Terminology (CDT): The primary coding system used for dental billing is the CDT code set. CDT codes are developed by the American Dental Association (ADA) and are used to identify dental procedures and services. For example, a routine dental exam might have a code like D0120, while a filling might be coded as D2140.
ICD-10 Codes: These are used to indicate the diagnosis or medical condition that requires dental treatment. For example, an ICD-10 code may describe tooth decay, gum disease, or another dental issue.
CPT Codes: Though CPT (Current Procedural Terminology) codes are typically used for medical billing, some dental practices may use them for specific procedures that are part of medical services (e.g., orthodontic treatments, or surgical dental procedures).
Insurance Verification: Before providing services, the dental office verifies that the patient’s insurance is active and that the planned procedures are covered. This often involves contacting the insurance company or using an online payer portal.
Benefit Breakdown: Understanding the specifics of the patient's dental insurance plan, including coverage limits, co-pays, deductibles, and out-of-pocket maximums, is essential to avoid surprises for both the provider and the patient.
Electronic vs. Paper Claims: Most dental offices now submit claims electronically through a practice management software system, which is faster and more efficient. However, paper claims may still be used in some cases.
Claim Form: The primary form used for submitting dental insurance claims is the ADA Dental Claim Form (often referred to as the CMS-1500 form in medical billing). This form includes information about the patient, provider, diagnosis, and procedures performed.
Claim Adjudication: Once submitted, the insurance company processes the claim and determines how much they will pay for the covered services. The insurer will send an Explanation of Benefits (EOB) to the dental office and the patient, showing what was covered, what was denied, and what the patient’s responsibility is.
Payment Posting: The dental office receives payments from the insurance company (or the patient) and posts those payments to the patient’s account. Any remaining balance that the patient owes is then communicated to them, often through a billing statement.
Appealing Denied Claims: If a claim is denied, dental billers must identify the reason (e.g., incorrect coding, missing information, or medical necessity issues) and appeal the denial by providing additional information or corrections.
Resubmission: Some claims are simply rejected due to errors or missing information. In these cases, the dental biller resubmits the claim with the correct details to avoid the claim being written off.
Patient Statements: After the insurance company has paid its portion, the remaining balance is billed to the patient. This may include the patient’s deductible, co-pays, or any non-covered services.
Payment Plans: Some dental offices offer payment plans for patients who cannot afford to pay the balance in full upfront.
Collections: If patients fail to pay their bills, the dental office may initiate a collections process, including sending reminders, setting up payment arrangements, or working with a collections agency.
Key Differences Between Dental Billing and Medical Billing
CDT Codes vs. CPT/ICD-10 Codes: Dental billing primarily uses CDT codes to identify dental procedures, while medical billing uses CPT and ICD-10 codes. While both types of billing use codes to describe services, dental codes are specific to dental care.
Claim Forms: Dental billing typically uses the ADA Dental Claim Form for submitting claims, while medical billing uses the CMS-1500 form.
Dental vs. Medical Procedures: Dental billing focuses on services related to oral health, such as cleanings, fillings, extractions, and orthodontics. Medical billing, on the other hand, deals with a broad range of healthcare services beyond dental care, such as surgeries, doctor visits, and hospitalizations.
Preventive Care: Many dental insurance plans heavily focus on preventive care (e.g., routine cleanings, exams) and limit coverage for restorative or cosmetic procedures. This differs from medical insurance, which may have broader coverage for diagnostic and therapeutic services.
Dental insurance typically works differently from health insurance, with a focus on preventative care and specific coverage limits. Some dental plans have higher co-pays and deductibles, and there are more restrictions on coverage for certain treatments.
Medical insurance plans tend to be more complex, with a broader scope of coverage and often higher reimbursement rates for certain procedures.
In dental billing, a treatment plan is often presented before procedures are performed, especially for costly treatments like orthodontics or oral surgery. Insurance companies may require prior authorization for certain procedures.
In medical billing, prior authorization may also be required for certain services, but treatment planning is typically less formalized compared to dental billing, where treatment plans are commonly used to outline services and costs upfront.
Challenges in Dental Billing
Dental claims are often denied for reasons such as incorrect coding, missing documentation, or services not being covered by insurance. It can be time-consuming to resubmit claims and appeal denials.
Some insurance companies take a long time to process claims, which can delay payments to dental offices and affect their cash flow.
When a patient has multiple dental insurance policies, dental billing must manage coordination of benefits to ensure that the claims are processed correctly and that the correct insurer pays for the services rendered.
Patients may not fully understand their insurance benefits, leading to confusion about their financial responsibility, especially when it comes to co-pays, deductibles, and non-covered services.
Major dental procedures, such as implants, orthodontics, and surgeries, often involve more complex billing due to higher costs, multiple visits, and greater documentation requirements.
Best Practices for Dental Billing
Ensure that all dental procedures are accurately coded using the appropriate CDT codes. Accurate coding helps reduce claim denials and delays.
Submit claims as soon as possible to meet insurance company deadlines and avoid delays in reimbursement.
Always verify patient insurance eligibility and benefits before providing services to ensure that the patient’s plan covers the procedures planned.
Track denials and address them promptly. If necessary, file appeals to ensure reimbursement is received.
Communicate the cost of procedures and patient responsibility clearly upfront, and provide accurate estimates for out-of-pocket costs to avoid surprises.
Dental offices should use specialized practice management software to streamline billing processes, track claims, and improve overall efficiency.
Dental billing is a specialized process within the broader medical billing industry, with its own set of codes, claim forms, and payer policies. Dental billing professionals work to ensure that dental practices are reimbursed for the services they provide by submitting accurate claims, following up on denials, and managing patient billing. Effective dental billing practices are essential for maintaining healthy cash flow and minimizing claim denials, ensuring that dental providers are compensated fairly for their work.
