What 58660 covers

Code 58660 represents laparoscopic release of adhesions involving the fallopian tubes or ovaries, also called salpingolysis or ovariolysis. A gynecologic surgeon uses instruments passed through small abdominal incisions to free tissue restricted by fibrous bands. Common settings include pelvic adhesions after prior surgery, inflammation, or endometriosis when the adhesions are treated rather than merely observed during inspection.

Select this code for the adhesiolysis actually performed, and document the affected structures, the adhesions treated, and the operative work. Distinguish that work from removal of an adnexa or excision of a pelvic lesion, which may point to a different procedure code. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. CMS applies endoscopy-family pricing when related endoscopies are performed together. A bilateral adjustment does not apply, and modifier 50 is inappropriate. Assistant-at-surgery payment may be available, co-surgeons are permitted, 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.

58660 billing questions

When should 58660 be selected instead of a code for lesion excision?

Use 58660 when the operative work releases adhesions tethering a tube or ovary. When the main work is excision of pelvic lesions, consider 58662 instead.

Can adhesiolysis be reported with another laparoscopic procedure?

Report it only when the operative record supports distinct therapeutic adhesiolysis, rather than adhesions being encountered or released as part of the other procedure. CMS applies endoscopy-family pricing when related endoscopies are performed together.

Should modifier 50 be used when adhesions are treated on both sides?

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

What documentation supports reporting 58660?

Document the involved tube or ovary, the adhesions treated, and the operative steps showing that they were released. The record should distinguish this work from inspection alone or another primary procedure.

What postoperative care is included in the global period?

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

May an assistant or co-surgeon be paid for this procedure?

CMS indicates that assistant-at-surgery payment may be available and co-surgeons are permitted. Team surgery is not permitted.

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.
