What 64420 covers
An intercostal nerve block places local anesthetic, with or without steroid, near one nerve running beneath a rib to interrupt chest-wall pain. Anesthesiologists, pain physicians, and surgeons may perform it for localized pain after rib injury or thoracic surgery, or for intercostal neuralgia, in an office, procedure suite, or hospital.
Report 64420 for one targeted intercostal nerve; when additional intercostal nerves are blocked in the same session, report 64421 for each additional nerve. The record should identify the side and nerve or level treated, clinical indication, medication, technique, and response. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral treatment, modifier 50 is paid at 150%. When procedures are performed in the same session, the highest-valued procedure is paid in full and the others receive the standard multiple-procedure reduction. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.

64420 billing questions
When should I use 64420 instead of 64421?
Use 64420 for the first, single intercostal nerve treated. Report 64421 for each additional intercostal nerve blocked in the same session.
How is bilateral treatment reported?
For bilateral treatment, report modifier 50. CMS pays the bilateral procedure at 150%.
What documentation supports 64420?
Document the indication, side and intercostal nerve or level treated, medication and technique, and the patient's response.
Is same-day postoperative care included?
Yes. The 0-day global period includes same-day preoperative and postoperative care.
How does the multiple-procedure reduction affect 64420?
When it is performed with other procedures in the same session, the highest-valued procedure is paid in full and the others receive the standard 50% reduction.
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.
