K57.92 is a billable diagnosis code used to specify a medical diagnosis of diverticulitis of intestine, part unspecified, without perforation or abscess without bleeding. The code K57.92 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code K57.92 might also be used to specify conditions or terms like diverticulitis, diverticulitis of gastrointestinal tract or diverticulitis of intestine.

Unspecified diagnosis codes like K57.92 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.

Information for Patients


Diverticulosis and Diverticulitis

Diverticula are small pouches that bulge outward through the colon, or large intestine. If you have these pouches, you have a condition called diverticulosis. It becomes more common as people age. About half of all people over age 60 have it. Doctors believe the main cause is a low-fiber diet.

Most people with diverticulosis don't have symptoms. Sometimes it causes mild cramps, bloating or constipation. Diverticulosis is often found through tests ordered for something else. For example, it is often found during a colonoscopy to screen for cancer. A high-fiber diet and mild pain reliever will often relieve symptoms.

If the pouches become inflamed or infected, you have a condition called diverticulitis. The most common symptom is abdominal pain, usually on the left side. You may also have fever, nausea, vomiting, chills, cramping, and constipation. In serious cases, diverticulitis can lead to bleeding, tears, or blockages. Your doctor will do a physical exam and imaging tests to diagnose it. Treatment may include antibiotics, pain relievers, and a liquid diet. A serious case may require a hospital stay or surgery.
