Understanding the specific ICD-10 codes for diverticulitis is essential for accurate and compliant medical billing, especially for those specializing in gastroenterology medical coding. Medical coding outsourcing companies need to stay well updated on the latest coding guidelines to ensure proper reimbursement for client physicians and avoid costly billing errors. This post highlights the key aspects of coding for diverticulitis and the benefits of medical coding outsourcing to enhance accuracy and efficiency.
Understanding Diverticulitis and Its Coding Challenges
A common gastroenterology condition, diverticulitis refers to small pouches or pockets (diverticula) that occur within the wall or lining of any specific portion of the digestive tract. Generally, the condition is categorized based on severity, complications, and the presence or absence of abscesses, perforation, or fistulas. The complexity of these classifications makes coding for gastrointestinal conditions such as diverticulitis particularly challenging.
ICD-10 Codes for Diverticulitis
Diagnosis of diverticulosis involves a detailed medical history review, physical examination, blood tests and symptom evaluation to analyze bowel movements and other signs of pain and tenderness. Diagnosis tests like CT scan, X-ray, or a colonoscopy may be performed. If the gastroenterologist suspects that a person may have diverticulitis, additional tests may be ordered. The physician documentation in the medical record determines the coding and sequencing for diverticulosis. Accurate ICD-10 coding captures the specific type and severity of diverticulitis, which may influence treatment plans and insurance reimbursements.
In ICD-10-CM, diverticulitis is coded using the K57 ICD-10 code series. The codes include location (small, large or small and large intestine), with or without perforation or abscess, and with or without bleeding.
- K57 Diverticular disease of intestine
- K57.0 Diverticulitis of small intestine with perforation and abscess
- K57.00 …… without bleeding
- K57.01 …… with bleeding
- K57.1 Diverticular disease of small intestine without perforation or abscess
- K57.10 Diverticulosis of small intestine without perforation or abscess without bleeding
- K57.11 Diverticulosis of small intestine without perforation or abscess with bleeding
- K57.12 Diverticulitis of small intestine without perforation or abscess without bleeding
- K57.13 Diverticulitis of small intestine without perforation or abscess with bleeding
- K57.2 Diverticulitis of large intestine with perforation and abscess
- K57.20 …… without bleeding
- K57.21 …… with bleeding
- K57.3 Diverticular disease of large intestine without perforation or abscess
- K57.30 Diverticulosis of large intestine without perforation or abscess without bleeding
- K57.31 Diverticulosis of large intestine without perforation or abscess with bleeding
- K57.32 Diverticulitis of large intestine without perforation or abscess without bleeding
- K57.33 Diverticulitis of large intestine without perforation or abscess with bleeding
- K57.4 Diverticulitis of both small and large intestine with perforation and abscess
- K57.40 …… without bleeding
- K57.41 …… with bleeding
- K57.5 Diverticular disease of both small and large intestine without perforation or abscess
- K57.50 Diverticulosis of both small and large intestine without perforation or abscess without bleeding
- K57.51 Diverticulosis of both small and large intestine without perforation or abscess with bleeding
- K57.52 Diverticulitis of both small and large intestine without perforation or abscess without bleeding
- K57.53 Diverticulitis of both small and large intestine without perforation or abscess with bleeding
- K57.8 Diverticulitis of intestine, part unspecified, with perforation and abscess
- K57.80 …… without bleeding
- K57.81 …… with bleeding
- K57.9 Diverticular disease of intestine, part unspecified, without perforation or abscess
- K57.90 Diverticulosis of intestine, part unspecified, without perforation or abscess without bleeding
- K57.91 Diverticulosis of intestine, part unspecified, without perforation or abscess with bleeding
- K57.92 Diverticulitis of intestine, part unspecified, without perforation or abscess without bleeding
- K57.93 Diverticulitis of intestine, part unspecified, without perforation or abscess with bleeding

Best Practices for Coding Diverticulitis in Gastroenterology Billing
- Detailed Documentation: As part of accurate coding, physicians must provide detailed descriptions, including – location (small intestine, large intestine, or both) presence of complications like abscess or perforation and associated bleeding. Partnering with a reliable digestive health coding specialist ensures that documentation matches the coding requirements.
- Use of Combination Codes: Many ICD-10 codes for diverticulitis are combination codes. Combination codes describe the condition and associated complications. Coders must identify and apply the correct combination of codes in order to avoid under- or over-coding.
- Importance of Updates: ICD-10 codes are subject to regular, annual updates. Medical coders need to stay well updated with these changes to avoid billing errors in diverticulitis medical coding. This in turn reduces the risk of claim denials due to outdated coding practices.
Gastroenterology medical billing and coding can be challenging. ICD-10 coding for diverticulitis requires attention to detail and thorough understanding of the associated conditions and complications. Partnering with an experienced gastroenterology medical coding company ensures accurate coding and efficient revenue management. With the complexities of medical billing and coding, professional support can help physicians report diverticulosis using the right ICD-10 medical codes – which is essential to maximize reimbursement and avoid denials.
