When an injection is the sole service provided, what is the correct billing procedure?

When an injection is the sole service provided, the correct billing procedure involves reporting both the administration procedure code and the drug code. This approach ensures that both the service performed (the administration of the injection) and the specific drug or biological substance used are accurately documented and billed.

Injections require a separate code to describe the administration process, which reflects the healthcare provider's work involved in giving the injection. Additionally, the drug code is necessary to detail the specific medication administered, which is important for both reimbursement purposes and patient safety. By reporting both codes, the billing accurately represents the services rendered during the patient encounter.

This procedure aligns with the guidelines set forth by coding authorities, ensuring compliance with billing practices and promoting proper reimbursement. Therefore, option B captures the entire scope of the service provided during the injection administration.
