Which modifier indicates that anesthesia was administered by the surgeon?

The modifier that indicates anesthesia was administered by the surgeon is -47. This modifier is specifically used in cases where the surgeon provides anesthesia during a procedure, which is an integral part of the surgical process. Using -47 helps clarify that the anesthesia was part of the surgical service, as opposed to being managed by an anesthesiologist or nurse anesthetist.

In coding scenarios, it's important to specify who provided the anesthesia to maintain accurate billing and to reflect the level of care provided during a surgical procedure. By applying this modifier, it ensures that the surgical procedure and the associated anesthesia are properly documented and reimbursed appropriately.

Understanding the correct application of this modifier is crucial for accurate coding practices, as it affects how claims are processed and how services are valued within the healthcare system.
