Summary & Overview
CPT 38100: Open Splenectomy, Complete Excision
CPT code 38100 denotes an open splenectomy — a complete excision of the spleen via an incision into the abdominal cavity. This procedure is performed for acute and chronic indications including traumatic splenic rupture, hemolytic anemias refractory to medical therapy, and splenic malignancies. As a major abdominal operation, CPT 38100 is significant for hospital resource use, perioperative risk profiles, and policy considerations around surgical admission and reimbursement pathways.
Key national payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis covers payer coverage conventions, typical sites of service, and the clinical contexts that justify use of the code.
Readers will find a concise clinical context for CPT 38100, expected service setting and resource implications, common modifiers used with the code, and where available, payer-specific coverage patterns and administrative considerations. The publication summarizes benchmarks and policy-relevant items that affect billing and reimbursement for open splenectomy at a national level.
Billing Code Overview
CPT code 38100 describes a splenectomy by laparotomy: an open surgical procedure in which the provider makes an incision into the abdominal cavity and performs a complete excision of the spleen. The service is performed for conditions such as traumatic splenic rupture, hemolytic anemia, or primary splenic malignancy.
Service type: Surgical — Open splenectomy
Typical site of service: Inpatient surgical suite or operating room with postoperative inpatient care
Clinical & Coding Specifications
Clinical Context
A typical patient is a 34-year-old male presenting to the emergency department after blunt abdominal trauma with hemodynamic instability and signs of intra-abdominal hemorrhage. FAST exam demonstrates free fluid and CT scan confirms a grade IV splenic laceration with active contrast extravasation. After resuscitation in the ED and failure of nonoperative management (including transfusion and angioembolization not feasible or unsuccessful), the surgical team proceeds to operative management: an open exploratory laparotomy under general anesthesia with a complete splenectomy. The intraoperative workflow includes a midline or left subcostal incision, rapid control of hemorrhage, mobilization of the spleen, ligation of the splenic artery and vein at the hilum, division of ligamentous attachments, hemostasis, irrigation, and abdominal closure. Postoperative care involves ICU monitoring for bleeding and infection, immunizations for encapsulated organisms per guidelines, and documentation of indications (traumatic rupture), procedure details, estimated blood loss, transfusions, and attending surgeon attribution for coding and billing purposes.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the splenectomy required substantially greater effort, time, or technical difficulty than usual and documentation supports the increased work. |
