What 64418 covers

The clinician places an injection at the suprascapular nerve, which supplies sensation to parts of the shoulder. Pain medicine physicians, anesthesiologists, physiatrists, and other clinicians may use the block diagnostically or therapeutically for shoulder pain, including pain associated with rotator cuff disease or glenohumeral arthritis. The injected medication may be anesthetic, steroid, or both; the service is defined by the nerve targeted, not simply by an injection into the shoulder joint.

Report 64418 when documentation identifies the suprascapular nerve as the injection target and supports the clinical indication, side, approach, and medication administered. The code has a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral treatment, modifier 50 is paid at 150%. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Medicare does not pay an assistant at surgery for this service; 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.

64418 billing questions

How is 64418 different from a shoulder joint injection?

64418 targets the suprascapular nerve. An injection placed into the shoulder joint itself is a different service and should not be selected based only on the shared shoulder-pain indication.

When should 64450 be considered instead?

Use 64418 when the suprascapular nerve is the target. Code 64450 is for an injection targeting a peripheral nerve or branch without a more specific code for that nerve.

What documentation supports reporting 64418?

Document the shoulder-pain indication, the suprascapular nerve as the target, laterality, injection approach, and medication administered.

Can ultrasound guidance be reported separately?

When ultrasound needle guidance is performed and documented, 76942 may be separately reportable. The record should support the guidance service as well as the nerve injection.

How does Medicare pay when both sides are treated?

For bilateral treatment, Medicare pays 150% when the service is reported with modifier 50.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures in that session are subject to the standard multiple-procedure 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.
