Code Description

ICD-10 K52.29 is a billable code used to indicate a diagnosis of other allergic and dietetic gastroenteritis and colitis.

Key Diagnostic Point:

K52.29 refers to other allergic and dietetic gastroenteritis and colitis, which encompasses a range of gastrointestinal disorders characterized by inflammation of the stomach and intestines due to allergic reactions or dietary factors. Clinically, patients may present with symptoms such as abdominal pain, diarrhea, vomiting, and bloating. The anatomy involved includes the stomach, small intestine, and large intestine, where inflammation can disrupt normal digestive processes. Disease progression can vary, with some patients experiencing acute episodes while others may have chronic symptoms. Diagnostic considerations include a thorough patient history, identification of potential allergens or dietary triggers, and exclusion of other gastrointestinal conditions. Laboratory tests, imaging studies, and endoscopic evaluations may be utilized to confirm the diagnosis and rule out other causes of gastroenteritis and colitis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Diagnostic complexity: Requires identification of specific allergens or dietary triggers.
  • Treatment complexity: May involve dietary modifications, medications, and monitoring.
  • Documentation requirements: Detailed clinical history and symptom tracking are essential.
  • Coding specificity: Requires precise coding to differentiate from other gastroenteritis types.

Audit Risk Factors

  • Common coding errors: Misidentification of the cause of gastroenteritis.
  • Documentation gaps: Incomplete patient history or lack of allergy testing results.
  • Billing challenges: Difficulty in justifying the medical necessity of specific treatments.

Enhanced Specificity

ICD-10 Improvements

The clinical significance of K52.29 lies in its association with allergic reactions and dietary intolerances, which can significantly affect patients' quality of life and nutritional status. Understanding the epidemiology of these conditions can help healthcare providers identify at-risk populations and implement preventive measures. Quality measures may include tracking patient outcomes related to dietary modifications and symptom management, which can ultimately reduce healthcare utilization and improve population health.

ICD-9 vs ICD-10

The clinical significance of K52.29 lies in its association with allergic reactions and dietary intolerances, which can significantly affect patients' quality of life and nutritional status. Understanding the epidemiology of these conditions can help healthcare providers identify at-risk populations and implement preventive measures. Quality measures may include tracking patient outcomes related to dietary modifications and symptom management, which can ultimately reduce healthcare utilization and improve population health.

Reimbursement & Billing Impact

Reimbursement considerations include ensuring that the medical necessity for allergy testing and dietary consultations is well-documented. Common denials may arise from insufficient evidence linking the condition to dietary factors or allergies. Coding best practices involve using K52.29 in conjunction with appropriate procedure codes for diagnostic tests and treatments, ensuring that all documentation supports the diagnosis and treatment plan.

Frequently Asked Questions

What specific conditions are covered by K52.29?

K52.29 covers conditions such as allergic gastroenteritis due to food allergies, dietary intolerances (like lactose intolerance), and other non-specific diet-related colitis that do not fall under more specific codes.

When should K52.29 be used instead of related codes?

K52.29 should be used when the gastroenteritis or colitis is specifically linked to allergic reactions or dietary factors that are not classified under other specific codes, such as K52.0 for infectious gastroenteritis.

What documentation supports K52.29?

Documentation should include a detailed patient history, identification of potential allergens, results from allergy testing, dietary logs, and clinical notes that outline the symptoms and their correlation with dietary intake.
