Clinical InformationClinical

  • Carcinoma, Pancreatic Ductal

    carcinoma that arises from the pancreatic ducts. it accounts for the majority of cancers derived from the pancreas.

  • Cystic Fibrosis

    an autosomal recessive genetic disease of the exocrine glands. it is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator expressed in several organs including the lung, the pancreas, the biliary system, and the sweat glands. cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in airway obstruction; chronic respiratory infections; pancreatic insufficiency; maldigestion; salt depletion; and heat prostration.

  • Insulin Infusion Systems

    portable or implantable devices for infusion of insulin. includes open-loop systems which may be patient-operated or controlled by a pre-set program and are designed for constant delivery of small quantities of insulin, increased during food ingestion, and closed-loop systems which deliver quantities of insulin automatically based on an electronic glucose sensor.

  • Islets of Langerhans

    irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the pancreas among the exocrine acini. each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. there are four major cell types. the most abundant beta cells (50-80%) secrete insulin. alpha cells (5-20%) secrete glucagon. pp cells (10-35%) secrete pancreatic polypeptide. delta cells (~5%) secrete somatostatin.

  • Nesidioblastosis

    an inherited autosomal recessive syndrome characterized by the disorganized formation of new islets in the pancreas and congenital hyperinsulinism. it is due to focal hyperplasia of pancreatic islet cells budding off from the ductal structures and forming new islets of langerhans. mutations in the islet cells involve the potassium channel gene kcnj11 or the atp-binding cassette transporter gene abcc8, both on chromosome 11.

  • 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.

  • Pancreas Divisum

    anatomic variants in pancreatic ducts characterized by failure of fusion of the ventral and dorsal endodermal buds. pancreas divisum results in inadequate or no communication between dorsal and ventral ducts. while most cases are asymptomatic, it may be associated with recurrent pancreatitis.

  • Pancreas Transplantation

    the transference of a pancreas from one human or animal to another.

  • Pancreas, Artificial

    devices for simulating the activity of the pancreas. they can be either electromechanical, consisting of a glucose sensor, computer, and insulin pump or bioartificial, consisting of isolated islets of langerhans in an artificial membrane.

  • Pancreas, Exocrine

    the major component (about 80%) of the pancreas composed of acinar functional units of tubular and spherical cells. the acinar cells synthesize and secrete several digestive enzymes such as trypsinogen; lipase; amylase; and ribonuclease. secretion from the exocrine pancreas drains into the pancreatic ductal system and empties into the duodenum.

  • Pancreatic Neoplasms

    tumors or cancer of the pancreas. depending on the types of islet cells present in the tumors, various hormones can be secreted: glucagon from pancreatic alpha cells; insulin from pancreatic beta cells; and somatostatin from the somatostatin-secreting cells. most are malignant except the insulin-producing tumors (insulinoma).

  • Pancrelipase

    a preparation of hog pancreatic enzymes standardized for lipase content.

  • Shwachman-Diamond Syndrome

    an inherited syndrome characterized by exocrine pancreatic insufficiency; hematologic abnormalities (e.g., bone marrow hypoplasia), and skeletal abnormalities (e.g., metaphyseal chondroplasia). germline mutations in the sbds gene are associated with shwachman-diamond syndrome.

Patient EducationClinical

Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Questions About D13.6Overview

Is D13.6 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report benign neoplasm of pancreas on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does D13.6 group to?

When benign neoplasm of pancreas is the principal diagnosis on an inpatient stay, it groups to MS-DRG 438, 439, 440, with relative weights from 0.6214 to 1.6302 depending on complications. Higher weights mean higher Medicare reimbursement.

What is the ICD-9 equivalent of D13.6?

Under the General Equivalence Mappings, benign neoplasm of pancreas converts to ICD-9-CM 211.6 (benign neoplasm pancreas). The mapping is a direct match.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
