What 58674 covers

A gynecologic surgeon uses laparoscopic access to place and guide a radiofrequency device into uterine leiomyomas and ablate the targeted tissue. Intraoperative ultrasound guidance and monitoring are part of this service. It is performed in an operating room for patients undergoing a uterus-sparing fibroid procedure; it is distinct from removing fibroids through laparoscopic or hysteroscopic excision.

Report the code when the operative documentation supports laparoscopic ablation of uterine fibroid tissue. Document the approach, ablation method, treated fibroids, and use of intraoperative ultrasound. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available, and co-surgeons are permitted; team-surgery payment is not permitted.

How to choose

58580Fibroid ablation
Both codes describe radiofrequency ablation of uterine fibroids with ultrasound guidance and monitoring. Choose 58674 for laparoscopic access and 58580 for transcervical hysteroscopic access.
58545Laparoscopic myomectomy
This code covers laparoscopic fibroid ablation. Code 58545 describes laparoscopic removal of a limited number of fibroids by myomectomy.
58546Laparoscopic myomectomy
Use 58674 for laparoscopic ablation; 58546 describes laparoscopic myomectomy for greater fibroid number or weight, with fibroids excised rather than ablated.

58674 billing questions

How is this different from hysteroscopic fibroid ablation?

This code is for laparoscopic access to ablate fibroids. The hysteroscopic counterpart uses transcervical access.

Can intraoperative ultrasound guidance be reported separately?

Ultrasound guidance and monitoring are included in this service. They should not be separately reported solely for guidance integral to the ablation.

Should modifier 50 be used when fibroids are treated on both sides of the uterus?

No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available, and co-surgeons are permitted. Team-surgery payment is not permitted for this code.

How does payment change when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures 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.
