CPT 48001 Pancreatic Drainage: Reimbursement | OpenPayer

Summary & Overview

CPT 48001: Pancreatic and Enteric Drainage Tube Placement

CPT code 48001 denotes a surgical drainage procedure performed for acute pancreatitis in which drains are placed around the pancreas and small openings are made in the gallbladder, stomach, and jejunum to accommodate drainage tubes. This code represents a complex, invasive procedure often performed in hospitalized patients with infected or symptomatic peripancreatic fluid collections. Nationally, accurate coding for this service matters for clinical documentation, resource use tracking, and appropriate claim adjudication for high-acuity surgical care.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context on when this procedure is used, typical sites of service, and common billing considerations. The publication also outlines benchmarks and payer coverage patterns where available, procedural documentation priorities, and relevant policy developments affecting surgical drainage and enteric/gallbladder tube placement for pancreatitis.

This summary is intended for clinicians, coding professionals, and policy analysts seeking a concise national overview of CPT code 48001, its clinical role, and the payment and documentation implications that commonly accompany high-acuity pancreatic drainage procedures. Data not available in the input will be identified in specific sections.

Billing Code Overview

CPT code 48001 describes a surgical drainage procedure for a patient with acute pancreatitis. The provider places drains around the pancreas and creates small openings in the gallbladder, stomach, and jejunum to accommodate drainage tubes.

Service Type: Surgical drainage and enteric/gallbladder drainage tube placement

Typical Site of Service: Operating room or interventional procedure suite (inpatient or procedural setting)

Clinical & Coding Specifications

Clinical Context

A typical patient is a middle-aged adult admitted with severe acute pancreatitis complicated by infected peripancreatic necrosis and persistent fluid collections causing systemic inflammatory response and sepsis. The patient has ongoing abdominal pain, fever, leukocytosis, and imaging (contrast-enhanced CT) demonstrating multiloculated peripancreatic fluid and necrotic debris. Interventional surgery is consulted after failed conservative therapy and antibiotic trials. In the operating room or interventional suite, the provider performs surgical drainage: placing peripancreatic drains, and creating controlled small enteric and biliary openings to facilitate external drainage — specifically making small openings in the gallbladder, stomach, and jejunum for placement of drainage tubes when indicated by anatomy and source control needs. Typical workflow includes preoperative resuscitation, broad-spectrum antibiotics, informed consent documenting risks (bleeding, infection, fistula), intraoperative image guidance as needed, placement of multiple drains, confirmation of drain position, and postoperative monitoring with serial labs, imaging, and drain output assessment. The procedure is commonly performed in an inpatient acute care hospital setting, often in an operating room or interventional radiology suite, and may involve general surgery, hepatobiliary surgery, or interventional radiology teams.

`K85.2`	Alcohol-induced acute pancreatitis	Common etiology of severe pancreatitis leading to necrosis and fluid collections requiring drainage.
`K86.0`	Alcohol-induced chronic pancreatitis	Chronic changes with superimposed acute exacerbation may require drainage of fluid collections.
