What 64435 covers

This service places anesthetic, with or without steroid, around a paracervical (uterine) nerve to create a regional block. Gynecologists, anesthesiologists, and pain physicians may perform it in an office, procedure room, or hospital. A typical setting is pain control for a cervical or uterine procedure; the code is selected for the paracervical nerve target, not simply because an injection is near the pelvis.

Document the nerve targeted, side, clinical reason, and procedure performed. The code 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 occur in one session, the highest-valued procedure is paid in full and other procedures are paid at 50%. An assistant at surgery is not paid; 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.

64435 billing questions

How is this different from a pudendal nerve block?

This code is for injection at the paracervical (uterine) nerve. Use the pudendal nerve code, 64430, when the documented target is the pudendal nerve.

When should modifier 50 be reported?

When the paracervical nerve injection is performed bilaterally, report modifier 50. CMS pays the bilateral procedure at 150%.

What does the 0-day global period include?

Same-day preoperative and postoperative care is included in the procedure. The global period is 0 days.

What documentation supports reporting this code?

Document the paracervical nerve target, laterality, reason for the block, and the injection performed. The record should distinguish this target from another pelvic nerve.

How does CMS handle this with another procedure 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.

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.
