CPT 48020 Pancreatic Stone Removal Reimbursement | OpenPayer

Summary & Overview

CPT 48020: Removal of Stone from the Pancreas

CPT code 48020 denotes surgical removal of a stone from the pancreas, a targeted operative procedure to relieve obstruction or address complications from pancreatic calculi. Nationally, this code is relevant where specialized gastrointestinal and surgical services manage obstructive pancreatopathy, postoperative recovery, and potential complication mitigation. Payers evaluate claims for medical necessity, site-of-service appropriateness, and coding alignment with operative notes.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, typical sites of service, and payer coverage considerations. The publication summarizes benchmark information, coding and billing considerations relevant to institutional and professional claims, and policy updates affecting prior authorization and documentation requirements.

This summary equips hospital billing managers, surgical coders, and compliance officers with a concise reference to the clinical intent of 48020, the primary payers likely to adjudicate these claims, and the types of topics—benchmarks, policy clarifications, and documentation expectations—covered in the full publication.

Service type: Surgical removal of pancreatic stone
Typical site of service: Hospital operating room or major ambulatory surgery center

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient with a history of chronic pancreatitis presents with recurrent epigastric pain, nausea, and radiographic evidence of an obstructing pancreatic duct stone on MRCP. After endoscopic evaluation with ERCP and failed endoscopic fragmentation, the surgical team schedules an operative procedure to remove the pancreatic duct stone. The patient is taken to the operating room, placed under general anesthesia, and monitored by anesthesia and perioperative nursing. The pancreatic duct is exposed via either a pancreaticojejunostomy or direct ductotomy depending on intraoperative findings. The surgeon identifies and extracts the calculus, irrigates the duct, assesses duct patency, and may place a stent if indicated. Hemostasis is secured and the incision closed. Postoperative care includes pain control, monitoring for pancreatic leak or infection, serial abdominal examinations, laboratory evaluation of amylase/lipase, and imaging if complications are suspected. Billing uses 48020 to report removal of a stone from the pancreas when performed surgically.

ICD-10 Code	Description	Clinical Relevance
`K86.1`	Chronic pancreatitis	Common indication for pancreatic duct stone removal due to ductal obstruction and pain.
`K85.9`	Acute pancreatitis, unspecified	Stones can precipitate acute exacerbations; operative removal may be required when endoscopy fails.
`K86.8`	Other specified diseases of pancreas	Includes obstructive or chronic degenerative conditions associated with ductal calculi.
`K91.89`	Other postprocedural complications and disorders of digestive system	Relevant when addressing complications from prior procedures contributing to stone formation or obstruction.
`K92.9`	Gastrointestinal hemorrhage, unspecified	Included as a potential complication to monitor for in perioperative management.
