Other diseases of pancreas (K86) ICD-10-CM
The K86 code range covers other diseases of pancreas with 9 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the K86 range.
Exocrine Pancreatic Insufficiency
A malabsorption condition resulting from greater than 10% reduction in the secretion of pancreatic digestive enzymes (LIPASE; PROTEASES; and AMYLASE) by the EXOCRINE PANCREAS into the DUODENUM. This condition is often associated with CYSTIC FIBROSIS and with chronic PANCREATITIS.
Pancreas
A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
Pancreatic Fistula
Abnormal passage communicating with the PANCREAS.
About the K86 Code Range
The ICD-10 code section K86 covers various other diseases of the pancreas, including forms of chronic pancreatitis, cysts, pseudocysts, and pancreatic insufficiency. These codes are specifically used to classify and document pancreatic conditions that do not fall under diabetes.
This section includes K86.0 for alcohol-induced chronic pancreatitis, also known as inflammation of the pancreas caused by alcohol or chronic pancreatitis due to chronic alcoholism. The K86.1 code describes other chronic pancreatitis types such as idiopathic, hereditary, or obstructive chronic pancreatitis, as well as related conditions like pseudocysts or recurrent pancreatitis. K86.2 and K86.3 differentiate between pancreatic cysts and pseudocysts, which are fluid-filled sacs often related to pancreatitis. The code K86.81 identifies exocrine pancreatic insufficiency, a condition where the pancreas fails to produce enough digestive enzymes. Codes K86.8, K86.89, and K86.9 cover other specified or unspecified pancreatic diseases, including rare disorders, pancreatic duct issues, and complications such as pancreatic necrosis or fibrosis. These codes are essential for precise clinical documentation and help direct adequate patient care related to pancreatic health.
