What 61751 covers

A neurosurgeon uses stereotactic planning and CT or MRI guidance to direct instruments through a cranial opening to an intracranial lesion and obtain tissue. The service is typically performed in an operating room for a suspected brain tumor or another lesion that requires pathologic diagnosis; the specimen is sent for examination. The operative report should identify the target, the stereotactic approach, the imaging guidance used, and the tissue obtained.

Select this code when the biopsy is performed with CT or MRI guidance; distinguish it from stereotactic biopsy without that imaging guidance. The code has a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and reduces the others to 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is barred by statutory restriction; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61751 billing questions

How does this differ from 61750?

Use 61751 for stereotactic intracranial biopsy performed with CT or MRI guidance. Code 61750 describes stereotactic biopsy without that imaging guidance.

What documentation supports 61751?

Document the intracranial target, stereotactic approach, use of CT or MRI to guide the biopsy, and tissue obtained.

Can modifier 50 be used for bilateral targets?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not suitable.

Is assistant-at-surgery payment available?

No. CMS lists a statutory restriction on assistant-at-surgery payment for 61751.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others are paid at 50%.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
