What type of codes are used to identify injectables in an office or outpatient setting?

The correct choice is HCPCS Level II codes because these codes are specifically designed to identify products, supplies, and certain services that are not included in the CPT coding system, which primarily covers medical procedures and services. HCPCS Level II codes provide a standardized coding structure for items such as injectables, durable medical equipment, and non-physician services in office or outpatient settings.

For instance, when a healthcare provider administers a vaccine or any other injectable medication, the corresponding HCPCS Level II code is used to accurately represent the service or product provided. This facilitates proper billing and reimbursement from insurance companies.

In contrast, ICD-10 codes are used primarily for diagnosing and classifying diseases, while CPT codes represent medical procedures and services. Modifier codes, on the other hand, are used to provide additional information about the service performed or to indicate that a service has been altered in some way. None of these codes are suitable for specifically identifying injectables in the same way that HCPCS Level II codes are.
