D49.0 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of unspecified behavior of digestive system. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2025 through September 30, 2026.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic adenoid (pharynx) (tissue) ; Neoplasm, neoplastic alimentary canal or tract NEC ; Neoplasm, neoplastic alveolar ; Neoplasm, neoplastic alveolar mucosa ; Neoplasm, neoplastic alveolar mucosa lower ; Neoplasm, neoplastic alveolar mucosa upper ; Neoplasm, neoplastic alveolar ridge or process mucosa ; etc

Unspecified diagnosis codes like D49.0 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: NEO072

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

• Ampulla of Vater

a dilation of the duodenal papilla that is the opening of the juncture of the common bile duct and the main pancreatic duct, also known as the hepatopancreatic ampulla.

• Appendiceal Neoplasms

tumors or cancer of the appendix.

• Appendix

a worm-like blind tube extension from the cecum.

• Colon

the segment of large intestine between the cecum and the rectum. it includes the ascending colon; the transverse colon; the descending colon; and the sigmoid colon.

• Duodenal Neoplasms

the area covering the terminal portion of esophagus and the beginning of stomach at the cardiac orifice.

• Barrett Esophagus

a condition with damage to the lining of the lower esophagus resulting from chronic acid reflux (esophagitis, reflux). through the process of metaplasia, the squamous cells are replaced by a columnar epithelium with cells resembling those of the intestine or the salmon-pink mucosa of the stomach. barrett's columnar epithelium is a marker for severe reflux and precursor to adenocarcinoma of the esophagus.

• Esophageal Motility Disorders

disorders affecting the motor function of the upper esophageal sphincter; lower esophageal sphincter; the esophagus body, or a combination of these parts. the failure of the sphincters to maintain a tonic pressure may result in gastric reflux of food and acid into the esophagus (gastroesophageal reflux). other disorders include hypermotility (spastic disorders) and markedly increased amplitude in contraction (nutcracker esophagus).

• Esophageal Mucosa

circular innermost layer of the esophagus wall that mediates esophageal peristalsis which pushes ingested food bolus toward the stomach.

• Esophageal Neoplasms

tumors or cancer of the esophagus.

• Esophagus

the muscular membranous segment between the pharynx and the stomach in the upper gastrointestinal tract.

• Acalculous Cholecystitis

inflammation of the gallbladder wall in the absence of gallstones.

• Cholecystitis

inflammation of the gallbladder; generally caused by impairment of bile flow, gallstones in the biliary tract, infections, or other diseases.

• Gallbladder

a storage reservoir for bile secretion. gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the cystic duct to the duodenum, for degradation of dietary lipid.

• Gallbladder Diseases

diseases of the gallbladder. they generally involve the impairment of bile flow, gallstones in the biliary tract, infections, neoplasms, or other diseases.

the anteriorly located rigid section of the palate.

• Palate, Soft

a movable fold suspended from the posterior border of the hard palate. the uvula hangs from the middle of the lower border.

• 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.

• Pyloric Stenosis

narrowing of the pyloric canal with varied etiology. a common form is due to muscle hypertrophy (pyloric stenosis, hypertrophic) seen in infants.

• Pylorus

the region of the stomach at the junction with the duodenum. it is marked by the thickening of circular muscle layers forming the pyloric sphincter to control the opening and closure of the lumen.

• Bariatric Surgery

surgical procedures aimed at affecting metabolism and producing major weight reduction in patients with morbid obesity.

abnormal distention of the stomach due to accumulation of gastric contents that may reach 10 to 15 liters. gastric dilatation may be the result of gastric outlet obstruction; ileus; gastroparesis; or denervation.

• Gastric Fistula

abnormal passage communicating with the stomach.

• Gastric Stump

that portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. it is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

ICD-9-CM: 239.0

This is a direct match with no additional mapping qualifiers. The absence of a flag generally means the mapping is considered exact or precise. In other words, the ICD-10 code maps cleanly to the ICD-9 code without qualification, approximation, or needing multiple codes.

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Digestive Diseases

When you eat, your body breaks food down to a form it can use to build and nourish cells and provide energy. This process is called digestion.

Your digestive system is a series of hollow organs joined in a long, twisting tube. It runs from your mouth to your anus and includes your esophagus, stomach, and small and large intestines. Your liver, gallbladder and pancreas are also involved. They produce juices to help digestion.

There are many types of digestive disorders. The symptoms vary widely depending on the problem. In general, you should see your doctor if you have:

• Blood in your stool
• Changes in bowel habits
• Severe abdominal pain
• Unintentional weight loss
• Heartburn not relieved by antacids
