What 64640 covers

This service involves intentionally disabling a targeted peripheral nerve or branch to reduce pain, commonly by injecting a neurolytic agent. Interventional pain physicians and other qualified clinicians may perform it for selected cases of persistent neuralgia or nerve pain, including pain associated with an injured nerve or neuroma. The specific nerve and treatment approach distinguish this service from codes assigned to particular nerves or nerve groups.

Select the code based on the nerve treated and the documented procedure, not simply the presence of an injection or nerve block. The record should identify the target nerve or branch, the condition treated, and the neurolytic method. Related postoperative visits are included in the 10-day global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral treatment, modifier 50 is paid at 150%. 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.

64624Genicular nerve ablation
Choose 64624 for the specified genicular nerve treatment; 64640 is the broader code for other peripheral nerve targets.

64640 billing questions

When should 64640 be selected instead of a nerve-specific code?

Use 64640 for neurolytic treatment of another peripheral nerve or branch. Use a more specific code when the treated nerve is named in a separate code, such as the pudendal or common digital nerve.

Does an ordinary nerve block support 64640?

A diagnostic or therapeutic nerve block alone is not the neurolytic treatment reported by this code. The documentation should support intentional neurolytic treatment of the identified nerve or branch.

What should the procedure note identify?

Document the nerve or branch treated, the clinical condition, and the neurolytic method. The note should distinguish the treatment from a temporary anesthetic block.

How is bilateral treatment reported?

For bilateral treatment, report modifier 50; CMS pays the bilateral procedure at 150%.

How are multiple procedures in one session paid?

CMS pays the highest-valued procedure in full and the other procedures at 50% when performed in the same session.

Are related postoperative visits separately included?

Related postoperative visits during the 10-day global period are included in this procedure's payment.

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.
