Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 64450 covers

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.
