K63.9 is a billable diagnosis code used to specify a medical diagnosis of disease of intestine, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
Unspecified diagnosis codes like K63.9 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.

Patient Education
Colonic Diseases
Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. Some of these include:
- Colorectal cancer
- Colonic polyps - extra tissue growing in the colon that can become cancerous
- Ulcerative colitis - ulcers of the colon and rectum
- Diverticulitis - inflammation or infection of pouches in the colon
- Irritable bowel syndrome - an uncomfortable condition causing abdominal cramping and other symptoms
Treatment for colonic diseases varies greatly depending on the disease and its severity. Treatment may involve diet, medicines and in some cases, surgery.

Small Intestine Disorders
Your small intestine is the longest part of your digestive system - about twenty feet long! It connects your stomach to your large intestine (or colon) and folds many times to fit inside your abdomen. Your small intestine does most of the digesting of the foods you eat. It has three areas called the duodenum, the ileum, and the jejunum.
Problems with the small intestine can include:
- Bleeding
- Celiac disease
- Crohn's disease
- Infections
- Intestinal cancer
- Intestinal obstruction
- Irritable bowel syndrome
- Ulcers, such as peptic ulcer
Treatment of disorders of the small intestine depends on the cause.

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.
