Pain management

About 64451: Image-guided sacroiliac nerve block

Report this code for an image-guided anesthetic or steroid injection targeting nerves that innervate the sacroiliac joint, such as for suspected SI-joint pain.

This service is an injection of anesthetic, steroid, or both around nerves that carry sensation from the sacroiliac joint. Clinicians commonly target the L5 dorsal ramus and sacral lateral branches when evaluating or treating suspected SI-joint pain. Pain medicine physicians, anesthesiologists, and physiatrists may perform it in an office or outpatient facility, using fluoroscopy or CT to guide needle placement.

Report the code when the target is the nerves supplying the SI joint, rather than the joint space itself. The record should identify the side and nerve targets, document image guidance, and describe the injectate and clinical indication. Needle placement and imaging guidance are included. The procedure has a 0-day global period, so same-day preoperative and postoperative care are included. For bilateral services, modifier 50 is paid at 150%. In the same session, the highest-valued procedure is paid in full and other procedures are reduced to 50%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.

64451 billing questions

How is this different from an SI-joint injection?

This code is for injections targeting nerves that innervate the SI joint. Code 27096 is for an injection into the SI-joint space.

Is image guidance separately reported?

No. The service includes fluoroscopic or CT guidance and needle placement.

Can I report this for both sides?

Yes. Report bilateral work with modifier 50; CMS pays the bilateral procedure at 150%.

How does the multiple-procedure reduction affect same-session services?

CMS pays the highest-valued procedure in full and reduces the other procedures to 50% when performed in the same session.

What documentation supports reporting this code?

Document the SI-innervating nerve targets, laterality, image guidance, injectate, and reason for the injection. The record should make clear that the target is neural, not the joint space.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
