About 61522: Infratentorial brain abscess excision

Reports craniotomy or craniectomy to excise an abscess in the infratentorial brain, such as the cerebellum or posterior fossa.

A neurosurgeon uses a craniotomy or craniectomy to reach and remove an abscess in the infratentorial portion of the brain. A cerebellar or other posterior fossa abscess is a typical clinical example. The service is performed in an operating room, generally in a hospital setting, and is distinct from removal of a tumor or meningioma.

Select this code when the operative report supports excision of an infratentorial brain abscess through the described cranial approach; document the abscess location and the work performed. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61522 billing questions

How does this differ from 61514?

61522 is for an infratentorial brain abscess, while 61514 is for a supratentorial brain abscess. Use the documented location of the abscess.

Is this code for stereotactic aspiration?

This code describes excision through a craniotomy or craniectomy. Do not select it solely because an abscess was treated; the operative approach and work must support excision.

Can modifier 50 be reported for abscesses on both sides?

No. Modifier 50 is inappropriate for this procedure. The operative report should support the service and the treated abscess location.

What postoperative care is included?

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

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

What happens when another procedure is performed in the same session?

CMS pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the other procedures.
