D13.6 Benign neoplasm of pancreas

ICD-10-CM D13.6: Benign neoplasm of pancreas

ICD-10-CM code D13.6 represents a benign neoplasm of the pancreas and is used for a patient confirmed to have this diagnosis. The code falls under the digestive system neoplasm category D13. Clinical literature discusses various pancreatic cystic neoplasms, noting that some lesions are benign while others are precancerous or malignant. This reference outlines code structure and clinical context. 4 5 6 1

Plain-language overview

Code D13.6 is intended for use on a patient confirmed to have a benign neoplasm of the pancreas, which clinical literature describes as a type of pancreatic mass. Sources note that pancreatic masses can be identified as either benign or malignant neoplasms. 6

What this code represents

The ICD-10-CM code D13.6 represents the diagnosis of a benign neoplasm of the pancreas. It is organized within the D13 category, which covers benign neoplasms of other and ill-defined parts of the digestive system. 5 4

Coding details

Within the ICD-10-CM hierarchy, D13.6 is grouped under the D10-D36 range for benign neoplasms, except benign neuroendocrine tumors. This code is distinct from D13.7, which is used for a benign neoplasm of the endocrine pancreas. 5

Clinical coding references distinguish D13.6 from malignant pancreatic neoplasm codes, such as C25.9 for malignant neoplasm of the pancreas. The D13.6 code description specifically excludes the islets of Langerhans. 6

Clinical context

Clinical literature discusses various pancreatic cystic neoplasms, noting that differential diagnosis can include benign macrocystic serous cystadenomas, precancerous mucinous lesions, or malignant solid neoplasms. A cystic lymphangioma of the pancreas is identified as a benign neoplasm discovered incidentally in asymptomatic individuals. 1

Documentation considerations

Clinical sources identify that evaluating macrocystic lesions of the pancreas involves differentiating between benign serous cystadenomas and precancerous mucinous cystic neoplasms. This diagnostic process relies on clinical features and imaging data. 1

What the sources add

While clinical literature details the differential diagnosis and management of pancreatic cystic neoplasms, coding references establish the specific ICD-10-CM hierarchy and code definitions. Together, these sources show how clinical findings of a benign pancreatic neoplasm correspond to the D13.6 code. 1 5

Coding references map islet cell adenomas to the endocrine pancreas code D13.7, while D13.6 is used for benign neoplasm of the pancreas excluding islets of Langerhans. This distinction separates the endocrine and digestive system classifications of pancreatic neoplasms. 3 6
