What 61545 covers

A neurosurgeon removes a tumor arising in brain tissue through an operative cranial approach, such as a craniotomy or craniectomy. The procedure is generally performed in a hospital operating room for a patient with an intracranial tumor requiring surgical removal. The operative report should establish the tumor as the target and describe the approach and excision performed.

Select this code when the documented operation matches brain-tumor excision, not removal of a pituitary gland or a tumor arising from skull bone. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

61545 billing questions

How do I distinguish this from pituitary tumor surgery?

Use this code when the operative target is a tumor in brain tissue. When the procedure removes the pituitary gland, consider the pituitary excision codes instead.

What documentation supports reporting this code?

The operative report should identify the brain tumor as the target and describe its surgical removal and the cranial approach used.

Can modifier 50 be reported?

No. CMS identifies bilateral adjustment as inappropriate for this code.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full; other procedures in the session are subject to the standard multiple-procedure reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.

What care is included in the global period?

The 90-day global period includes the preoperative visit on the day before surgery and 90 days of related postoperative care.
