Dental insurance verification and accuracy in reporting ICD-10 and CDT dental codes on the claims submitted to insurance companies are crucial for timely reimbursement. The ICD-10 diagnosis codes signify particular dental diseases, disorders and symptoms, while the CDT procedural codes are used to report various diagnostic, preventive, restorative, endodontics, periodontics, removable prosthodontics, maxillofacial prosthetics, implant services, fixed prosthodontics, oral and maxillofacial surgery, orthodontics, and adjunctive general services on dental insurance claims.
Dental practitioners help patients suffering from various dental problems and prompt service is essential for excellent patient care. Some of the most common dental problems dentists treat include:
- Erosion of teeth
- Dental caries
- Gingivitis
- Periodontitis
- Endodontic treatment
- Resin restoration

Insurance Eligibility Verification –an Important First Step
Insurance eligibility verification is a key step to ensure that the dental insurance claims are not denied. So, dental offices must review a patient’s benefits before they enter the office. Eligibility verification involves verifying that the patient’s information is up-to-date, his/her benefits are still active, and what is and is not covered by the insurance. For instance, if a patient is requesting a whitening procedure, you must verify whether their insurance plan will cover such a cosmetic procedure. Also, the rules of their benefits as regards frequency and waiting periods must be verified. Often, patients do not completely understand their own benefits and so the dental practice must know all details regarding the patient’s benefits. Only if the dental insurance verification is accurately done, the dentist will receive the due reimbursement.
A dental billing company can prove to be a valuable partner for busy dentists because they will proactively verify the patient’s insurance eligibility even before the patient’s appointment date. They will obtain prior authorizations for particular dentistry codes such as implants, scaling, root canal treatment, crowns and other procedures that require pre-authorization so that claim denials and delays are avoided. In addition, other details will also be verified such as policy status, plan exclusions, deductibles, claims mailing address, and pre-authorization number among others.
Dental billing companies can be entrusted with error-free dental billing and coding because their billing experts stay updated with the frequently changing dental codes. This ensures that dental practitioners can focus on providing patient care and considerably reduce the overhead expenses they might incur if in-house billing staff is hired.
