ICD-10-CM Code D13.9

Benign neoplasm of ill-defined sites within the digestive system

Version 2020 Billable Code Neoplasm Benign

Valid for Submission

D13.9 is a billable code used to specify a medical diagnosis of benign neoplasm of ill-defined sites within the digestive system. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D13.9 might also be used to specify conditions or terms like benign neoplasm of gastrointestinal tract, benign neoplasm of ileum, benign neoplasm of intestinal tract, benign neoplasm of meckel's diverticulum, benign neoplasm of spleen, benign stromal neoplasm of gastrointestinal tract, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: alimentary canal or tract NEC ; digestive organs, system, tube, or tract NEC ; gastrocolic ; gastrointestinal (tract) NEC ; intestine, intestinal ; intestine, intestinal tract NEC ; spleen, splenic NEC ; etc

These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Benign neoplasm of digestive system NOS
  • Benign neoplasm of intestine NOS
  • Benign neoplasm of spleen


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Diagnostic Related Groups

The ICD-10 code D13.9 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).

Table of Neoplasms

The code D13.9 is included 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.

Information for Patients

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.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

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
