Code Description

ICD-10 K31.819 is a billable code used to indicate a diagnosis of angiodysplasia of stomach and duodenum without bleeding.

Key Diagnostic Point:

Angiodysplasia of the stomach and duodenum without bleeding is a vascular malformation characterized by abnormal blood vessels in the gastrointestinal tract, particularly in the stomach and duodenum. Clinically, patients may present with nonspecific gastrointestinal symptoms such as abdominal pain, nausea, or dyspepsia, but often do not exhibit overt bleeding. The anatomy involved includes the mucosal and submucosal layers of the stomach and duodenum, where these vascular lesions can disrupt normal function. Disease progression may be slow, and while many patients remain asymptomatic, some may develop complications if the lesions become larger or if they lead to chronic inflammation. Diagnostic considerations include endoscopy, where angiodysplastic lesions may be visualized, and imaging studies such as CT scans or angiography may be utilized to assess the vascular structures. Biopsy may be performed to rule out malignancy, although it is not always necessary. Accurate diagnosis is essential for appropriate management and to differentiate from other gastrointestinal conditions such as peptic ulcers or malignancies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Diagnostic complexity: Requires imaging and endoscopic evaluation to confirm diagnosis.
  • Treatment complexity: Management may involve endoscopic interventions or monitoring.
  • Documentation requirements: Detailed clinical documentation is necessary to support diagnosis.
  • Coding specificity: Requires precise coding to differentiate from other gastrointestinal conditions.

Audit Risk Factors

  • Common coding errors: Misclassification with bleeding codes.
  • Documentation gaps: Lack of detailed clinical notes may lead to coding inaccuracies.
  • Billing challenges: Potential for denials if documentation does not support the diagnosis.

ICD-10 Improvements

The clinical significance of K31.819 lies in its potential to cause chronic gastrointestinal symptoms and impact patient quality of life. Although it may not lead to acute complications like bleeding, awareness of this condition is crucial for early diagnosis and management. Population health impact includes understanding the prevalence of gastrointestinal vascular malformations and their contribution to healthcare utilization patterns. Epidemiologically, angiodysplasia is more common in older adults, highlighting the need for targeted screening and management strategies in this demographic.

Frequently Asked Questions

What specific conditions are covered by K31.819?

K31.819 specifically covers angiodysplasia of the stomach and duodenum that is not associated with active bleeding. It is important to differentiate it from other gastrointestinal vascular lesions and conditions that may present with similar symptoms.

When should K31.819 be used instead of related codes?

K31.819 should be used when a patient has been diagnosed with angiodysplasia of the stomach or duodenum without any evidence of bleeding. If there is active bleeding, K31.81 should be selected instead.

What documentation supports K31.819?

Documentation should include clinical findings from endoscopic evaluations, imaging studies, and any relevant patient history that supports the diagnosis of angiodysplasia without bleeding.
