Code Description

ICD-10 E64.2 is a billable code used to indicate a diagnosis of sequelae of vitamin c deficiency.

Key Diagnostic Point:

Sequelae of vitamin C deficiency refers to the long-term effects and complications that arise from a prolonged lack of vitamin C in the diet, leading to conditions such as scurvy. Vitamin C is essential for the synthesis of collagen, a protein that helps maintain the integrity of connective tissues, skin, and blood vessels. Deficiency can result in symptoms such as fatigue, weakness, swollen and bleeding gums, joint pain, and anemia. Long-term sequelae may include chronic skin issues, delayed wound healing, and increased susceptibility to infections. In severe cases, it can lead to systemic complications affecting multiple organ systems. The condition is particularly concerning in populations with limited access to fresh fruits and vegetables, such as the elderly, those with malabsorption syndromes, or individuals with restrictive diets. Proper diagnosis and management are crucial to prevent irreversible damage and improve quality of life.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of nutritional deficiencies and their sequelae.
  • Documentation must specify the chronic nature of the deficiency.
  • Differentiating between acute and chronic manifestations can be challenging.
  • Potential overlap with other deficiency codes may complicate coding.

Audit Risk Factors

  • Inadequate documentation of the chronic nature of the deficiency.
  • Failure to link symptoms directly to vitamin C deficiency.
  • Misclassification of acute symptoms as sequelae.
  • Lack of evidence for dietary history or nutritional assessment.
