What 61312 covers

A neurosurgeon uses a craniotomy or craniectomy to reach and remove an extradural or subdural hematoma in the supratentorial compartment. The service is typically performed in a hospital operating room for conditions such as an acute intracranial bleed requiring surgical evacuation. The code identifies both the hematoma’s location and its compartment; it is not the code for an intracerebral clot or a hematoma below the tentorium.

The operative report should establish the supratentorial site, whether the collection is extradural or subdural, and that it was evacuated. The surgical approach and routine work integral to reaching and closing the operative site are part of the service. This major surgery includes 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. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this descriptor and anatomy.

How to choose

61313Hematoma evacuation
Choose 61313 when the hematoma is within brain tissue in the supratentorial compartment. This code is for an extradural or subdural collection above the tentorium.
61314Hematoma evacuation
Both codes describe extradural or subdural hematoma evacuation, but 61314 is for the infratentorial compartment; this code is supratentorial.
61322Cranial decompression
61322 describes cranial decompression without lobectomy, rather than evacuation of a specifically identified supratentorial extradural or subdural hematoma.

61312 billing questions

How does this code differ from 61313?

Use this code for a supratentorial extradural or subdural collection. Code 61313 describes evacuation of a hematoma within the brain tissue.

Can the craniotomy or craniectomy be reported separately?

The operative access is part of the hematoma evacuation service. Do not separately report routine access or closure as a second procedure.

Should modifier 50 be appended?

No. Modifier 50 is inappropriate for this code’s descriptor and anatomy.

How is the 90-day global period handled?

The day-before preoperative visit and 90 days of related postoperative care are included in the major-surgery global period.

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?

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