What 64425 covers

This service places anesthetic near the ilioinguinal and/or iliohypogastric nerves to evaluate or relieve pain in their distribution. Pain medicine physicians and anesthesiologists commonly perform it for groin or lower abdominal wall pain, including persistent pain after inguinal hernia repair. It may be performed in an office-based pain clinic or a hospital outpatient setting.

Select the code when the documented target is these nerves, rather than another named nerve or an unspecified peripheral nerve branch. The record should identify the nerve target, side, clinical indication, medication injected, and the patient’s response when relevant. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral service, modifier 50 is paid at 150%. CMS does not pay an assistant at surgery, and does not permit co-surgeons or team surgery for this service.

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.

64425 billing questions

When should this code be selected instead of 64450?

Use this code when the documented target is the ilioinguinal and/or iliohypogastric nerves. Code 64450 describes an injection for another peripheral nerve or branch not identified by a more specific code.

Can both nerves be addressed under this code?

The code identifies the ilioinguinal and iliohypogastric nerve targets. Document which nerve or nerves were injected and the side treated.

How is a bilateral injection reported?

For bilateral service, modifier 50 is paid at 150%. The documentation should support treatment on both sides.

Is same-day evaluation or postoperative care included?

Yes. The 0-day global period includes same-day preoperative and postoperative care.

How does CMS handle another procedure performed in the same session?

The highest-valued procedure is paid in full, and other procedures in the session are paid at 50% under the standard multiple procedure reduction.

What documentation supports reporting this nerve block?

Record the clinical indication, the ilioinguinal and/or iliohypogastric target, the side, the medication injected, and the response when relevant.

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.
