    ICD-10-CM Code For Other Diseases Of Pancreas: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K86 includes chronic and other specified diseases of the pancreas such as chronic pancreatitis, pancreatic cysts, and other non-neoplastic pancreatic disorders. These ICD-10-CM diagnosis codes are used to document patient encounters involving pancreatic inflammation, structural pancreatic abnormalities, or complications affecting pancreatic function and adjacent structures. Accurate coding within the ICD-10-CM K86 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM K86: Other Diseases Of Pancreas Overview

    The ICD-10-CM K86 code group captures non-neoplastic pancreatic disorders such as chronic pancreatitis, pancreatic cysts, and other specified or unspecified diseases of the pancreas. These diagnoses target the exocrine and sometimes endocrine functions of the pancreas and their structural complications. Accurate coding ensures that clinical detail and disease severity are reflected, which supports appropriate reimbursement and continuity of care.

    When to Use

    Use a code from this group when the clinician documents chronic pancreatitis, other specified pancreatic disease, or an unspecified pancreatic disorder as the reason for the encounter or treatment. Select the most specific K86 code that reflects etiology, complications, and laterality when applicable to accurately represent the clinical scenario.

    Typical Clinical Scenarios

    • An adult patient presents to the emergency department with sudden, severe epigastric pain radiating to the back, nausea, and elevated serum amylase/lipase consistent with an acute inflammatory process of the pancreas. Imaging shows focal necrosis and areas of pancreatic tissue destruction following recent heavy alcohol use; the encounter is for acute management and monitoring of pancreatic inflammation and necrosis, so an acute pancreatitis-related code from this group is assigned. Typical codes: K86.0, K86.1
    • A middle-aged patient with a long history of chronic alcohol use reports progressive, persistent upper abdominal pain, malabsorption, and weight loss; outpatient evaluation reveals pancreatic exocrine insufficiency with calcifications on CT and steatorrhea. This represents chronic pancreatic disease with functional impairment managed longitudinally, and a chronic pancreatitis or related sequelae code from this group is assigned. Typical codes: K86.2, K86.3
    • A hospitalized patient with known chronic pancreatitis develops recurrent episodes of pancreatic pseudocyst formation and secondary obstruction of the pancreatic duct, requiring interventional drainage and complicating their clinical course. Because this is a complication of underlying pancreatic disease (structural complication and other specified pancreatic disorder), a code for other specified pancreatic complications is used to capture the comorbidity impacting treatment. Typical codes: K86.81, K86.89
