What 64455 covers

A clinician injects anesthetic, steroid, or both around a plantar common digital nerve in the forefoot. The service is commonly performed in an office by a podiatrist, orthopedic clinician, or pain specialist for symptoms such as burning or radiating pain in the ball of the foot associated with suspected Morton's neuroma. The record should identify the treated nerve and side, the clinical indication, and the medication and injection performed.

Report 64455 for the plantar common digital nerve injection, rather than for an injection targeting a different peripheral nerve. The procedure has a 0-day global period, so same-day preoperative and postoperative care is included. For bilateral reporting, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. An assistant is paid only when medical necessity is documented; 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.

64455 billing questions

When should 64455 be used instead of 64450?

Use 64455 for an injection targeting a plantar common digital nerve, such as for Morton's neuroma. Use 64450 when the injected peripheral nerve or branch is not one of those nerves.

Is this code limited to steroid injections?

No. The service may involve anesthetic, steroid, or both. Document the medication administered and the plantar common digital nerve treated.

How is bilateral treatment reported?

CMS recognizes bilateral reporting with modifier 50 and pays it at 150%. Document the treated nerve and side for each foot.

Does the 0-day global period include same-day care?

Yes. Same-day preoperative and postoperative care is included in the procedure's 0-day global period.

Can an assistant or another surgeon be reported?

Assistant-at-surgery payment is allowed only with documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

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.
