What K86 covers · when clinicians use it
ICD-10 code K86 identifies Other diseases of pancreas in the U.S. ICD-10-CM clinical and billing record set. It sits within the Digestive System chapter (K00–K95), the section that groups related diagnoses so providers, payers, and public-health agencies report them consistently. Clinicians and medical coders apply K86 when an encounter's findings match the Other diseases of pancreas description, attaching it to the patient record so downstream insurance claims, payer audits, quality reporting, and epidemiological surveillance all reference the same standardized diagnosis. The ICD-10-CM is maintained by the Centers for Medicare & Medicaid Services and the CDC's National Center for Health Statistics, with an updated official code set released each U.S. fiscal year — always verify K86 against the current CMS/CDC release and your payer's documentation guidance before final use. This page summarizes documentation context for K86 and is a coding reference, not clinical, diagnostic, or billing advice.
K86 refers to Other diseases of pancreas, a group of disorders affecting the gallbladder, biliary tract, and pancreas. These include gallstones, inflammation, bile duct obstructions, pancreatitis, and complications due to systemic diseases. These conditions often present with abdominal pain and may require urgent medical or surgical care.
Symptoms
- Right upper abdominal pain – Common in gallbladder disease (K80–K82)
- Nausea and vomiting – Present in cholecystitis (K81) and pancreatitis (K85)
- Fever and chills – Indicate possible infection
- Jaundice – Suggests bile duct obstruction or involvement (K83, K87)
- Back pain and tenderness – Associated with acute pancreatitis
Diagnosis
Diagnosis of Other diseases of pancreas involves abdominal ultrasound, CT scan, MRCP, liver function tests, pancreatic enzymes (amylase, lipase), and sometimes ERCP. These help identify inflammation, obstruction, or underlying causes requiring intervention.
ICD10 Code Usage
ICD10 code K86 is used by gastroenterologists, hepatobiliary surgeons, ER physicians, and internists. It supports billing for imaging, hospital admission, endoscopic procedures, or surgical interventions like cholecystectomy or ERCP.
