What 61313 covers
A neurosurgeon performs a craniotomy or craniectomy to reach and evacuate a hematoma located within the supratentorial brain parenchyma. This code applies to an intracerebral collection; the operative report should distinguish it from blood outside the brain tissue, such as an extradural or subdural hematoma. These procedures are typically performed in an operating room for a patient requiring surgical management of an intracerebral hemorrhage.
Report the service when the documented site is supratentorial and the hematoma is intracerebral. The operative report should support both the location and the evacuation performed. CMS assigns a 90-day global period, including 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 other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this anatomy. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

61313 billing questions
How does this differ from 61312?
61313 is for a hematoma within supratentorial brain tissue. Code 61312 is for a supratentorial extradural or subdural hematoma.
Does the code include the craniotomy or craniectomy?
Yes. The reported service includes the cranial opening and evacuation of the intracerebral hematoma; do not separately report the access as another craniotomy or craniectomy service.
What documentation supports choosing this code?
The operative report should identify the hematoma as intracerebral, establish its supratentorial location, and describe its surgical evacuation.
Can modifier 50 be used?
No. CMS identifies bilateral adjustment as inappropriate for this code's descriptor and anatomy.
How are assistant and co-surgeon services handled?
An assistant at surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
