Insurance Basics

  • CDT Codes

    CDT (Current Dental Terminology) codes are developed and maintained by the American Dental Association (ADA). These codes are used by dentists to record dental procedures and services. Each code corresponds to a specific dental procedure or service, providing a standardized language for recording and reporting dental treatment.

  • CPT Codes

    Current Procedural Terminology (CPT) codes are a set of medical codes used to describe medical, surgical, and diagnostic procedures and services. These codes are maintained by the American Medical Association (AMA) and are used by healthcare providers and insurers to communicate uniform information about treatment performed.

  • ICD-10 Codes

    ICD-10 stands for the International Classification of Diseases, 10th Revision. These codes are used in various healthcare settings, including hospitals and outpatient clinics, to diagnose patients, track public health statistics, and process insurance claims and billing.

Integration in Medical Billing

In medical billing, both ICD-10 and CPT codes are used together to provide a complete picture of a patient's treatment. An insurance claim typically includes both:

  • ICD-10 codes to describe the patient's diagnosis.

  • CPT codes to describe the procedures performed to treat that diagnosis.

For example, if a patient is diagnosed with Amelogenesis Imperfecta (ICD-10 code K00.5: Hereditary disturbances in tooth structure, not elsewhere classified), and they have an office visit (CPT code 99213), both codes would be included in the insurance claim to justify the service provided and ensure proper reimbursement.

Understanding both coding systems is essential for accurate medical documentation, billing, and ensuring appropriate reimbursement for healthcare services.

Documentation Requirements

When using unlisted CPT codes, it is crucial to provide comprehensive documentation to justify the procedure and its medical necessity. This documentation typically includes:

  • A detailed description of the procedure performed

  • The reason for the procedure

  • Any relevant patient history and diagnostic information

  • Clinical notes and any imaging or tests that support the necessity of the procedure

Submitting Claims

When submitting claims, make sure to:

  • Include a narrative that explains why the unlisted code is being used.

  • Provide detailed documentation that clearly describes the procedure and its necessity.

  • Check with the insurance provider beforehand to ensure they accept unlisted codes and to understand their specific documentation requirements.

Using unspecified codes requires thorough and accurate documentation to ensure the claim is processed efficiently and reduces the risk of denial due to lack of information.
