What 58146 covers

A gynecologic surgeon removes uterine fibroids through an abdominal approach while preserving the uterus. This level is for cases meeting the high-burden threshold by fibroid count or total specimen weight: five or more intramural fibroids, or a total weight over 250 grams. The procedure is generally performed in a hospital or other surgical facility for patients seeking fibroid treatment without hysterectomy.

Select the level from the operative record, including the number of intramural fibroids removed and, when relevant, the total specimen weight. The record should establish the abdominal approach and the uterine-sparing procedure. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is 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.

58146 billing questions

How is this level distinguished from 58140?

Use this complex level when the case meets the threshold by count or weight: five or more intramural fibroids, or total specimen weight over 250 grams. Code 58140 is the lower abdominal myomectomy level.

Does the fibroid count or total weight determine the level?

Either qualifying measure supports the complex level. Document the intramural fibroid count and specimen weight when available so the operative record supports the selected code.

Is modifier 50 appropriate for fibroids on both sides of the uterus?

No. CMS identifies bilateral adjustment as inappropriate for this code; the descriptor and anatomy do not support modifier 50.

What postoperative care is included?

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

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures are subject to the standard 50% 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.
