Pancreatic NET Resection billing

Pancreatic NET Resection Billing Guide

Pancreatic neuroendocrine tumors (NETs) are rare, slow-growing tumors that arise from neuroendocrine cells in the pancreas. These tumors can be functional or non-functional, depending on whether they produce hormones that cause symptoms. Pancreatic NET resection is a surgical procedure aimed at removing these tumors, either partially or entirely, to alleviate symptoms and prevent further complications.

Understanding Pancreatic NET Resection

Pancreatic NET resection involves the surgical removal of neuroendocrine tumors from the pancreas. The procedure is performed by a qualified surgeon in a hospital setting under general anesthesia. The surgical approach may vary depending on the size, location, and characteristics of the tumor. It can include techniques such as:

Whipple Procedure: A complex surgery involving the removal of the head of the pancreas, the first part of the small intestine (duodenum), the gallbladder, part of the stomach, and lymph nodes near the pancreas.

Distal Pancreatectomy: Removal of the tail and sometimes a part of the body of the pancreas.

Enucleation: Removal of the tumor while leaving the pancreas intact.

The choice of procedure depends on the location and size of the tumor and the extent of its involvement with nearby structures.

Medical Billing and Coding for Pancreatic NET Resection

Billing for pancreatic NET resection requires accurate documentation and coding to ensure proper reimbursement. Here’s a comprehensive guide to the billing process:

Preoperative Considerations

Before the procedure, the following steps are essential:

Patient Consultation: Evaluation of the patient’s medical history, physical examination, and diagnosis of the pancreatic NET.

Preoperative Testing: Necessary tests, such as imaging studies (CT scans, MRI) and laboratory tests to assess the tumor and the patient’s overall health.

During the Procedure

During the surgical procedure:

Documentation: Detailed operative notes documenting the procedure performed, including the specific technique used (Whipple procedure, distal pancreatectomy, enucleation).

Pathology Report: Pathology report confirming the diagnosis of pancreatic NET and describing the tumor’s characteristics.

Post-operative Care

After the procedure:

Recovery: Monitoring the patient in the recovery room and documenting the recovery process.

Follow-up Care: Post-operative visits to manage the patient’s recovery and assess any complications.

Medical Billing Codes for Pancreatic NET Resection

Medical billing and coding for pancreatic NET resection involve the use of specific codes to accurately reflect the services provided. Here are the main codes involved:

CPT Codes: Common Procedure Terminology (CPT) codes for pancreatic resection include:

  • 48150: Pancreatectomy, distal, with or without splenectomy.
  • 48153: Pancreaticoduodenectomy (Whipple procedure).
  • 48155: Pancreatectomy, proximal subtotal, with total duodenectomy and partial gastrectomy.

ICD-10 Codes: International Classification of Diseases, 10th Revision (ICD-10) codes for pancreatic NETs include:

C25.4: Malignant neoplasm of endocrine pancreas.

C25.9: Malignant neoplasm of pancreas, unspecified.

Reimbursement and Documentation

Accurate documentation is crucial for reimbursement. Ensure the following:

Detailed Operative Notes: Description of the procedure, including specifics like tumor size, location, and extent of resection.

Pathology Report: Confirmation of the diagnosis of pancreatic NET and its characteristics.

Post-operative Notes: Details of the patient’s recovery and any complications.

Complications and Coding Challenges

Pancreatic NET resection can sometimes lead to complications that affect billing and coding. These complications may include:

Pancreatic Fistula: Leakage of pancreatic juices after surgery.

Delayed Gastric Emptying: Slow stomach emptying after surgery.

Postoperative Hemorrhage: Bleeding after surgery.

Each of these complications may require additional management and documentation, which impacts the billing process.

Medicare and Insurance Coverage

Medicare and insurance coverage for pancreatic NET resection can vary based on the patient’s plan and the specifics of the procedure. It’s essential to verify coverage and pre-authorizations before proceeding with surgery to avoid claim denials.

Documentation Tips for Success

Successful billing for pancreatic NET resection requires detailed documentation:

Clear Operative Notes: Include specifics about the tumor, the procedure performed, and any complications.

Pathology Reports: Ensure the pathology report confirms the diagnosis of pancreatic NET and provides details about the tumor.

Post-operative Care: Document the patient’s recovery, any complications, and follow-up care provided.

Coding for Specific Situations

Coding for specific situations in pancreatic NET resection:

Multiple Procedures: When multiple procedures are performed (e.g., Whipple procedure with splenectomy), ensure correct coding for each component.

Combined Procedures: If other organs are involved (e.g., duodenum, stomach), use appropriate combined procedure codes.

Compliance and Auditing

Healthcare providers should ensure compliance with coding guidelines and be prepared for audits:

Internal Audits: Regular audits of coding and billing practices to ensure accuracy and compliance.

External Audits: Medicare and insurance audits to verify that billed services meet documentation and 

coding requirements.

Reimbursement Challenges

Challenges in reimbursement for pancreatic NET resection may include:

Coding Errors: Incorrect use of CPT and ICD-10 codes can lead to claim denials.

Documentation Insufficiencies: Inadequate documentation can result in reduced or denied reimbursement.

Medical Necessity: Ensure that the procedure and services provided are medically necessary and supported by documentation.

Emerging Trends and Updates

Stay updated with emerging trends and updates in pancreatic NET resection billing:

New Codes: Changes in CPT and ICD-10 codes related to pancreatic surgery.

Reimbursement Policies: Updates in Medicare and insurance reimbursement policies.

Technological Advances: Advances in surgical techniques and their impact on billing and coding.


In conclusion, pancreatic NET resection is a specialized surgical procedure aimed at treating neuroendocrine tumors of the pancreas. Proper documentation and accurate coding are essential to ensure appropriate reimbursement for the services provided. By following this billing guide, healthcare providers can navigate the complexities of billing for pancreatic NET resection effectively and efficiently.
