CPT 39540 Traumatic Diaphragm Repair Reimbursement | OpenPayer

Summary & Overview

CPT 39540: Surgical Repair of Traumatic Diaphragmatic Hernia

CPT code 39540 designates surgical repair of a diaphragmatic hernia caused by an acute traumatic injury to the diaphragm and excludes neonatal hernia repair. This procedure is clinically significant because traumatic diaphragmatic injuries can be life-threatening, often requiring urgent operative intervention in acute care hospital settings. Nationally, appropriate coding of such emergent surgical repairs affects clinical documentation, hospital throughput, and payer claim adjudication for trauma and thoracic surgery services.

Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find guidance on the clinical context in which CPT code 39540 is used, typical sites of service, and the kinds of documentation elements that support billing for an acute traumatic diaphragmatic hernia repair. The publication also outlines common payer considerations and benchmarking topics relevant to billing and coding for emergent thoracic surgical procedures.

This summary is intended to inform hospital billing teams, surgical coders, and compliance officers about the role of CPT code 39540 in trauma and thoracic surgery workflows, and to provide a concise reference for national-level policy and reimbursement discussions. Data not available in the input includes specific payer policies, associated taxonomies, and related ICD-10 diagnosis codes.

Billing Code Overview

CPT code 39540 describes the surgical repair of a diaphragmatic hernia resulting from an acute traumatic injury to the diaphragm. This code applies to procedures that address defects in the diaphragm caused by trauma and explicitly excludes repair of neonatal hernias.

Service type: Surgical — trauma/acute thoracic surgery

Typical site of service: Operating room in an acute care hospital (inpatient or emergent/urgent procedural setting)

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult who sustains blunt or penetrating thoracoabdominal trauma after a motor vehicle collision or significant fall. The patient presents to the emergency department with respiratory distress, chest or abdominal pain, decreased breath sounds on the affected side, and possible bowel sounds in the chest. Imaging (chest radiograph and contrast-enhanced CT of chest/abdomen) demonstrates discontinuity of the diaphragm with herniation of abdominal contents into the hemithorax consistent with an acute traumatic diaphragmatic rupture. The surgical workflow includes emergency surgical consultation, resuscitation, airway management, preoperative anesthesia evaluation, and expedited operative repair. The operation is typically performed in an operating room under general anesthesia; approaches include transthoracic, transabdominal, or combined access depending on associated injuries and surgeon preference. Intraoperative steps include reduction of herniated viscera, debridement of the diaphragmatic tear edges, and primary repair with nonabsorbable sutures or mesh reinforcement when needed. Postoperative care includes intensive monitoring for respiratory compromise, analgesia, chest tube management if placed, and surveillance for associated intra-abdominal or thoracic injuries. Typical site of service: inpatient operating room, often emergent. Service type: emergent surgical repair of acute traumatic diaphragmatic hernia. Typical patient scenario: adult trauma patient with acute diaphragmatic rupture secondary to blunt thoracoabdominal trauma requiring urgent surgical repair using 39540 (repair of traumatic diaphragmatic hernia).

`S37.099A`	Unspecified injury of other and unspecified intra-abdominal organs, initial encounter	May capture associated intra-abdominal injuries identified during evaluation for diaphragmatic rupture.
`S36.819A`	Other intra-abdominal organ injury, initial encounter	Represents concomitant abdominal organ injury that influences operative planning.
`S39.012A`	Traumatic rupture of mesentery, initial encounter	Associated intra-abdominal trauma that can coexist with diaphragmatic rupture and affect repair.
