Code Description

ICD-10 D18 is a billable code used to indicate a diagnosis of hemangioma and lymphangioma, any site.

Key Diagnostic Point:

Hemangiomas and lymphangiomas are benign vascular tumors that can occur in various locations throughout the body. Hemangiomas are composed of a proliferation of blood vessels, while lymphangiomas are formed from lymphatic vessels. These tumors are most commonly found in infants and children, often presenting as raised, red or purple lesions on the skin. While most hemangiomas and lymphangiomas are asymptomatic and resolve spontaneously, some may require intervention if they cause complications such as bleeding, ulceration, or functional impairment. Surveillance is essential for larger or symptomatic lesions to monitor for potential complications. Although these tumors are benign, there is a small risk of malignant transformation, particularly in atypical cases or when they are associated with syndromes such as Klippel-Trenaunay syndrome. Accurate coding requires careful documentation of the tumor's location, size, and any associated symptoms or treatments.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and location of lesions
  • Differentiation between hemangiomas and lymphangiomas
  • Potential for associated syndromes requiring additional coding
  • Need for precise documentation of size and symptoms

Audit Risk Factors

  • Inadequate documentation of lesion characteristics
  • Failure to note associated symptoms or complications
  • Misclassification between hemangioma and lymphangioma
  • Lack of follow-up documentation for surveillance

Frequently Asked Questions

What is the difference between a hemangioma and a lymphangioma?

Hemangiomas are benign tumors made up of blood vessels, while lymphangiomas are composed of lymphatic vessels. Both can occur in various locations and may require different treatment approaches.
