Summary & Overview
CPT 44055: Open Surgical Derotation and Lysis of Intestinal Malrotation
CPT code 44055 represents an open surgical procedure to correct intestinal malrotation by derotation or reduction of volvulus and by division of bands that obstruct the duodenum. This operative code is clinically significant because intestinal malrotation and volvulus are potentially life‑threatening conditions requiring timely surgical management; accurate coding influences surgical case reporting, hospital resource use classification, and national procedure statistics. Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise presentation of what the code covers clinically and operationally, payer coverage considerations, and common billing contexts. The publication outlines typical sites of service and service type, summarizes common modifiers used with this code when available, and highlights areas where policy updates or billing clarifications frequently occur. It also provides benchmarking context and comparator codes where relevant. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 44055 describes a surgical procedure in which the surgeon makes an incision to access part of the intestine (excluding the rectum) and relieves intestinal malrotation. The operation involves reducing volvulus or derotating the malrotated bowel and may include division or lysis of peritoneal bands that kink the duodenum.
-
Service type: Open surgical correction of intestinal malrotation (lysis of Ladd bands and derotation/reduction)
-
Typical site of service: Inpatient or outpatient surgical setting, most commonly performed in an operating room under general anesthesia
Clinical & Coding Specifications
Clinical Context
A typical patient is a child or young adult presenting with recurrent, intermittent abdominal pain, bilious vomiting, failure to thrive, or acute intestinal obstruction. Physical exam may show abdominal distention and tenderness; imaging (upper GI series or CT) demonstrates malrotation with volvulus or obstruction of the duodenum. The operative workflow includes preoperative resuscitation and diagnostics, induction of general anesthesia, a midline or right upper quadrant laparotomy (or laparoscopic approach when appropriate), exploration of the small intestine, lysis or division of Ladd bands, counterclockwise derotation of volvulus if present, widening of the mesenteric base, and placement of the small bowel on the right and colon on the left. Intraoperative decisions include assessment of bowel viability and possible resection if necrosis is identified. Postoperative care includes monitoring for return of bowel function, pain control, and gradual advancement of diet. Typical site of service is an inpatient hospital operating room; ambulatory surgical centers are less common but may be used for stable, elective cases without anticipated bowel resection.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or time is substantially greater than typical for the procedure (extensive adhesiolysis, prolonged derotation, complex resection and anastomosis). |
