Diverticulosis ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Diverticulosis?

Diverticulosis is a common condition characterized by the presence of small pouches (diverticula) in the lining of the digestive tract, usually in the colon. To accurately code and document cases of diverticulosis, the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) provides specific codes. Here are some commonly used codes for this category, along with their clinical descriptions:

K57.20 - Diverticulosis of large intestine without perforation or abscess:
This code is used for uncomplicated cases of diverticulosis in the large intestine without any associated perforation or abscess formation.

K57.90 - Diverticulosis of intestine, part unspecified, without perforation or abscess:
This code is employed when diverticulosis is present in an unspecified part of the intestine without any perforation or abscess.

K57.50 - Diverticulosis of small intestine without perforation or abscess:
Used for documenting diverticulosis in the small intestine without any accompanying perforation or abscess.

K57.30 - Diverticulitis of large intestine without perforation or abscess:
This code describes diverticulitis without complications, such as perforation or abscess, specifically in the large intestine.

K57.92 - Diverticulosis of intestine, part unspecified, with perforation and abscess:
This code is assigned when diverticulosis is present in an unspecified part of the intestine and is complicated by perforation and abscess formation.

K57.52 - Diverticulitis of small intestine without perforation or abscess:

This code denotes diverticulitis without complications, such as perforation or abscess, specifically in the small intestine.

K57.32 - Diverticulitis of the large intestine with perforation and abscess:
Used to indicate diverticulitis with complications, specifically perforation and abscess formation, in the large intestine.

K57.40 - Diverticulosis of both small and large intestine without perforation or abscess:

This code is used when diverticulosis is present in the small and large intestines without any associated perforation or abscess.

K57.59 - Diverticulitis of small intestine with perforation and abscess:

Used to describe diverticulitis with complications, specifically perforation and abscess formation, in the small intestine.

‍K57.92 - Diverticulosis of intestine, part unspecified, with perforation and abscess:
This code is assigned when diverticulosis is present in an unspecified part of the intestine and is complicated by perforation and abscess formation.

Which Diverticulosis ICD codes are Billable: 

K57.20 - Diverticulosis of large intestine without perforation or abscess:

Yes, this code is billable as it specifically represents uncomplicated diverticulosis in the large intestine.

K57.90 - Diverticulosis of intestine, part unspecified, without perforation or abscess:

Yes, this code is billable as it encompasses diverticulosis in an unspecified part of the intestine without any associated perforation or abscess.

K57.50 - Diverticulosis of small intestine without perforation or abscess:

Yes, this code is billable as it indicates uncomplicated diverticulosis in the small intestine.

K57.30 - Diverticulitis of large intestine without perforation or abscess:

Yes, this code is billable as it represents diverticulitis without complications, such as perforation or abscess, specifically in the large intestine.

K57.92 - Diverticulosis of intestine, part unspecified, with perforation and abscess:

Yes, this code is billable as it denotes diverticulosis in an unspecified part of the intestine complicated by perforation and abscess formation.

K57.52 - Diverticulitis of small intestine without perforation or abscess:

Yes, this code is billable as it indicates diverticulitis without complications, such as perforation or abscess, specifically in the small intestine.

K57.32 - Diverticulitis of large intestine with perforation and abscess:

Yes, this code is billable as it represents diverticulitis with complications, specifically perforation and abscess formation, in the large intestine.

K57.40 - Diverticulosis of both small and large intestine without perforation or abscess:

Yes, this code is billable as it encompasses uncomplicated diverticulosis in small and large intestines.

K57.59 - Diverticulitis of small intestine with perforation and abscess:

Yes, this code is billable as it describes diverticulitis with complications, specifically perforation and abscess formation, in the small intestine.

K57.92 - Diverticulosis of intestine, part unspecified, with perforation and abscess:

Yes, this code is billable as it denotes diverticulosis in an unspecified part of the intestine complicated by perforation and abscess formation.

These codes are billable as they accurately classify and provide detailed information about the presence and nature of diverticulosis or diverticulitis and any associated complications, facilitating proper diagnosis, treatment, and billing.

Clinical Information

• Diverticulosis is a condition characterized by the presence of small pouches (diverticula) in the lining of the digestive tract, typically in the colon.
• It is most commonly seen in individuals over 40, and its prevalence increases with age.
• The exact cause of diverticulosis is not fully understood. However, it is believed to be associated with a combination of factors, including age, a low-fiber diet, and a sedentary lifestyle.
• Many individuals with diverticulosis remain asymptomatic and may only discover the condition incidentally during diagnostic tests or procedures.
• However, some individuals may experience symptoms such as abdominal pain (usually in the lower left side), bloating, changes in bowel habits (constipation or diarrhea), and occasional rectal bleeding.
• Complications can arise, leading to conditions like diverticulitis (inflammation of the diverticula), abscess formation, perforation, or even bowel obstruction.
• Diagnosis of diverticulosis typically involves a combination of medical history evaluation, physical examination, imaging tests (such as CT scan or colonoscopy), and ruling out other potential causes of symptoms.
• Treatment for uncomplicated diverticulosis usually focuses on lifestyle modifications, including increasing dietary fiber intake, hydration, and regular exercise.
• In cases of diverticulitis or complications, treatment may involve antibiotics, dietary restrictions (such as a clear liquid or low-residue diet), hospitalization and possible surgical intervention in severe cases.
• Regular follow-up and monitoring are important for individuals with diverticulosis to manage symptoms, prevent complications, and adjust treatment plans as necessary.

Synonyms Include:

• Colonic diverticulosis
• Diverticular disease
• Diverticular disorder
• Diverticular condition
• Diverticula of the colon
