CPT code 61304 is for a surgical procedure involving the exploration of the brain's supratentorial region through craniectomy or craniotomy.
CPT code 61304 is used to describe a surgical procedure known as a craniectomy or craniotomy, specifically for exploratory purposes in the supratentorial region of the brain. The supratentorial area is located above the tentorium cerebelli, a membrane that separates the cerebrum from the cerebellum. This procedure involves the removal of a portion of the skull (craniectomy) or the temporary removal of a bone flap from the skull (craniotomy) to allow the surgeon to access and examine the brain tissue in this region. It is typically performed to investigate and address conditions such as tumors, hemorrhages, or other abnormalities that may be affecting the brain's function.
For CPT code 61304, which involves a craniectomy or craniotomy, exploratory; supratentorial, the following modifiers may be applicable:
