CPT 44620 Enterostomy Closure Reimbursement | OpenPayer

Summary & Overview

CPT 44620: Enterostomy Closure to Restore Intestinal Continuity

CPT code 44620 denotes the surgical closure of a previously created enterostomy to restore intestinal continuity. This procedure is clinically significant because it reverses a prior intestinal diversion—commonly performed after recovery from disease, injury, or as part of staged colorectal care—and has implications for surgical resource utilization, perioperative planning, and payer policy. Nationally, enterostomy closure is a routine but potentially complex abdominal surgery that affects inpatient surgical volumes and post-acute care needs.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for enterostomy reversal, typical sites of service, and the service classification. The publication summarizes common modifiers and payer considerations, presents benchmarking context where available, and highlights policy or coding updates relevant to surgical closure of enterostomies. Intended audiences include surgical providers, billing and coding professionals, and payer policy teams seeking a clear reference on CPT code 44620 and its role in surgical care pathways.

Billing Code Overview

CPT code 44620 describes the surgical closure of a previously created enterostomy, restoring an uninterrupted gastrointestinal tract after a patient no longer requires intestinal diversion. The procedure involves takedown of an established stoma and reestablishing intestinal continuity.

Service type: Surgical, general/abdominal surgery
Typical site of service: Inpatient hospital operating room or ambulatory surgery center, depending on patient condition and clinical complexity

Clinical & Coding Specifications

Clinical Context

A typical patient is a 58-year-old who previously underwent a temporary loop ileostomy for distal colorectal anastomotic protection after low anterior resection for rectal cancer. After interval recovery, confirmed healing of the anastomosis by contrast study and colonoscopy, and satisfactory nutritional status, the surgical team schedules closure of the enterostomy to restore intestinal continuity. The patient presents to the hospital on the day of surgery for preoperative evaluation, receives general anesthesia, and undergoes adhesiolysis as needed, mobilization of the stoma limb, resection of the stoma tract if indicated, and a layered intestinal closure with restoration of bowel continuity and abdominal wall closure. The typical clinical workflow includes preoperative imaging or contrast enema, perioperative antibiotics, operative documentation of findings and technique, postoperative monitoring for return of bowel function, and discharge planning with stool softeners and follow-up for wound check and assessment of bowel function.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`K91.1`	Postprocedural intestinal obstruction	May indicate need to reverse diversion once obstruction risk resolved, or represent complication to consider before closure.
`K91.3`	Gastrointestinal complications, not elsewhere classified	Captures sequelae of prior intestinal surgery relevant to timing of closure.
`K63.5`	Polyp of colon	May be part of prior pathology that led to diversion; colon evaluation is required before closure.
`C20`	Malignant neoplasm of rectum	Prior rectal cancer often necessitates temporary diversion; confirmation of healing and remission informs timing of `44620`.
`I10`	Essential (primary) hypertension	Common comorbidity that affects perioperative risk assessment for stoma closure.
