Sigmoid Colon ICD-10-PCS Coding & Reimbursement

Summary & Overview

Sigmoid Colon: ICD-10-PCS Procedure Code Group Overview

International Classification of Diseases, 10th Revision, Procedure Coding System (ICD-10-PCS) codes under the group ICD-10 PCS 0DUN describe procedures that put biological or synthetic material on or in the sigmoid colon to reinforce or augment its function. Accurate ICD-10-PCS coding for this group is critical for correct inpatient reimbursement and for documenting the level of intervention and resource utilization.

Sigmoid Colon Overview

Procedures in this group involve placing biological or synthetic material to reinforce or augment the sigmoid colon, a segment of the large intestine within the gastrointestinal system. These procedures target the lower gastrointestinal tract and may be performed to support tissue integrity or correct structural defects. Accurate coding of these procedures is important for proper inpatient reimbursement and reflects the complexity and resources used during the intervention.

Typical Clinical Scenarios

An elderly patient with recurrent diverticulitis complicated by a large sigmoid wall defect and symptomatic colonic wall weakness presents for planned inpatient surgery to reinforce the sigmoid colon after resection and primary anastomosis to reduce risk of postoperative prolapse or persistent structural insufficiency. The procedure is performed electively during the inpatient admission to place biologic or synthetic material that physically augments the sigmoid colon wall to restore structural integrity. Codes: 0DUN47Z, 0DUN4JZ
A middle-aged patient admitted through the emergency department with acute sigmoid volvulus and ischemic but salvageable sigmoid colon undergoes urgent detorsion and reinforcement of the sigmoid colon to prevent recurrent torsion and support the compromised segment; the augmentation material is applied to support healing after repair. This urgent inpatient procedure is coded when biologic or synthetic material is put onto the sigmoid colon during the emergent operative intervention. Codes: 0DUN07Z, 0DUN0KZ
A patient with prior sigmoid colon surgery develops a postoperative anastomotic leak and chronic fistula, requiring a revision operation in the inpatient setting where the surgeon places reinforcing material onto the sigmoid colon to buttress the repair and promote durable closure. Coding reflects placement of material on or in the sigmoid colon during the corrective/revision procedure to address the complication. Codes: 0DUN77Z, 0DUN7JZ

ICD-10-PCS Codes

ICD-10-PCS codes are seven characters long — each position specifies, in order, the section, body system, root operation, body part, approach, device, and qualifier. Every code in this table shares the same first four characters, meaning they all describe the same root operation on the same body part. The remaining three characters distinguish the approach used, any device placed or maintained, and an additional qualifier.

When a procedure from this group is reported on an inpatient claim, the CMS MS-DRG grouper evaluates the principal diagnosis, procedure codes, and the presence of complicating conditions (CC) or major complicating conditions (MCC) to assign a Diagnosis-Related Group. The DRGs listed above represent the possible MS-DRG assignments for procedures in this group. Each DRG carries a relative weight used to calculate the Medicare inpatient prospective payment.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.
