Nerve injection
About 64450: Other peripheral nerve block injection
Report 64450 for an anesthetic and/or steroid injection targeting a peripheral nerve or branch that does not have a more specific CPT code.
A clinician injects anesthetic, steroid, or both around a peripheral nerve or branch not identified by a more specific nerve-block code. The block may be used to reduce pain or help evaluate whether a particular nerve is contributing to symptoms. Pain physicians, anesthesiologists, surgeons, and other clinicians may perform it in an office, outpatient procedure area, or hospital. The documented target must be the nerve or branch actually treated; this code is not a substitute for a code that names the nerve or anatomic target.
Report the service based on the documented nerve, indication, laterality, and injectate. The record should identify the target and support the clinical purpose of the block; for a diagnostic block, document the patient’s response when assessed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted, and co-surgeon and team-surgery billing are not permitted.

64450 billing questions
When should 64450 be chosen instead of a code for a named nerve?
Use 64450 when the treated peripheral nerve or branch does not have a more specific code. For a nerve with its own code, report that code rather than using 64450 as a general substitute.
What should the procedure note identify?
Document the nerve or branch treated, the clinical indication, laterality, and the anesthetic and/or steroid injected. For a diagnostic block, record the response when it is assessed.
How is a bilateral service reported?
Use modifier 50 for a bilateral procedure; CMS pays it at 150%.
How does the multiple-procedure reduction affect 64450?
When it is performed with other procedures in the same session, the highest-valued procedure is paid in full and the others are paid at 50%.
Can an assistant, co-surgeon, or surgical team be billed for this procedure?
Assistant-at-surgery payment is restricted. Co-surgeons and team surgery are not permitted for this code.
Are same-day preoperative and postoperative services included?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
