What 64461 covers

This service is a single-injection thoracic paravertebral nerve block using anesthetic medication, with or without steroid, to reduce pain in the relevant thoracic distribution. Anesthesiologists and acute pain or pain-management clinicians commonly perform it around thoracic procedures, including thoracotomy, or breast surgery. Imaging guidance may be used to place the injection and is included in the service. The block may be performed in an operating room or another procedural setting.

Select this code for one thoracic paravertebral injection site; report 64462 for each additional site when applicable. Document the indication, laterality, site count, medication, and guidance used. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral performance, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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.
