2022 ICD-10-CM Code K50.91

Crohn's disease, unspecified, with complications

Version 2021

Not Valid for Submission

ICD-10:K50.91
Short Description:Crohn's disease, unspecified, with complications
Long Description:Crohn's disease, unspecified, with complications

Code Classification

  • Diseases of the digestive system (K00–K93)
    • Noninfective enteritis and colitis (K50-K52)
      • Crohn's disease [regional enteritis] (K50)

K50.91 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of crohn's disease, unspecified, with complications. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Unspecified diagnosis codes like K50.91 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.

Specific Coding for Crohn's disease, unspecified, with complications

Non-specific codes like K50.91 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for crohn's disease, unspecified, with complications:

  • BILLABLE CODE - Use K50.911 for Crohn's disease, unspecified, with rectal bleeding
  • BILLABLE CODE - Use K50.912 for Crohn's disease, unspecified, with intestinal obstruction
  • BILLABLE CODE - Use K50.913 for Crohn's disease, unspecified, with fistula
  • BILLABLE CODE - Use K50.914 for Crohn's disease, unspecified, with abscess
  • BILLABLE CODE - Use K50.918 for Crohn's disease, unspecified, with other complication
  • BILLABLE CODE - Use K50.919 for Crohn's disease, unspecified, with unspecified complications

Information for Patients


Crohn's Disease

What is Crohn's disease?

Crohn's disease is a chronic disease that causes inflammation in your digestive tract. It can affect any part of your digestive tract, which runs from your mouth to your anus. But it usually affects your small intestine and the beginning of your large intestine.

Crohn's disease is an inflammatory bowel disease (IBD). Ulcerative colitis and microscopic colitis are other common types of IBD.

What causes Crohn's disease?

The cause of Crohn's disease is unknown. Researchers think that an autoimmune reaction may be one cause. An autoimmune reaction happens when your immune system attacks healthy cells in your body. Genetics may also play a role, since Crohn's disease can run in families.

Stress and eating certain foods don't cause the disease, but they can make your symptoms worse.

Who is at risk for Crohn's disease?

There are certain factors which can raise your risk of Crohn's disease:

What are the symptoms of Crohn's disease?

The symptoms of Crohn's disease can vary, depending where and how severe your inflammation is. The most common symptoms include

Some other possible symptoms are

Stress and eating certain foods such as carbonated drinks and high-fiber foods may make some people's symptoms worse.

What other problems can Crohn's disease cause?

Crohn's disease can cause other problems, including

How is Crohn's disease diagnosed?

Your health care provider may use many tools to make a diagnosis:

What are the treatments for Crohn's disease?

There is no cure for Crohn's disease, but treatments can decrease the inflammation in your intestines, relieve symptoms, and prevent complications. Treatments include medicines, bowel rest, and surgery. No single treatment works for everyone. You and your health care provider can work together to figure out which treatment is best for you:

Changing your diet can help reduce symptoms. Your provider may recommend that you make changes to your diet, such as

Some people also need go on special diet, such as a low-fiber diet.

Crohn disease

Crohn disease is a complex, long-lasting (chronic) disorder that primarily affects the digestive system. This condition involves an abnormal immune response that causes excess inflammation. It most often affects the intestinal walls, particularly in the lower part of the small intestine (the ileum) and portions of the large intestine (the colon). However, inflammation can occur in any part of the digestive system, from the mouth to the anus. The inflamed tissues become thick and swollen, and the inner surfaces of the digestive system may develop open sores (ulcers).

Crohn disease most commonly appears in a person's late teens or twenties, although the disease can begin at any age. Signs and symptoms tend to flare up multiple times throughout life. The most common features of this condition are persistent diarrhea, abdominal pain and cramping, loss of appetite, weight loss, and fever. Some people with Crohn disease have blood in the stool from inflamed tissues in the intestine; over time, chronic bleeding can lead to a low number of red blood cells (anemia). In some cases, Crohn disease can also cause inflammation affecting the joints, eyes, or skin.

Intestinal blockage is a common complication of Crohn disease. Blockages are caused by swelling or a buildup of scar tissue in the intestinal walls. Some affected individuals also develop fistulae, which are abnormal connections between the intestine and other tissues. Fistulae occur when ulcers break through the intestinal wall and passages form between loops of the intestine or between the intestine and nearby structures (such as the bladder, vagina, or skin).

Crohn disease is one common form of inflammatory bowel disease (IBD). Another type of IBD, ulcerative colitis, also causes chronic inflammation of the intestinal lining. Unlike Crohn disease, which can affect any part of the digestive system, ulcerative colitis typically causes inflammation only in the colon.
