Code Description

ICD-10 E01.1 is a billable code used to indicate a diagnosis of iodine-deficiency related multinodular (endemic) goiter.

Key Diagnostic Point:

Iodine-deficiency related multinodular goiter is a condition characterized by the enlargement of the thyroid gland due to insufficient iodine intake, leading to the development of multiple nodules within the gland. This condition is prevalent in regions where iodine is not adequately available in the diet, often referred to as endemic goiter. The thyroid gland requires iodine to synthesize thyroid hormones, which are crucial for regulating metabolism, growth, and development. When iodine levels are low, the thyroid compensates by enlarging, resulting in a goiter. Patients may present with symptoms such as neck swelling, difficulty swallowing, or breathing issues if the goiter is large enough. Thyroid function tests may reveal hypothyroidism, as the lack of iodine leads to decreased hormone production. In some cases, the goiter can become multinodular, with varying degrees of hormone production, potentially leading to hyperthyroidism in some nodules. Diagnosis typically involves clinical examination, imaging studies, and laboratory tests to assess thyroid hormone levels and iodine status.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between endemic and sporadic goiter
  • Understanding the relationship between iodine deficiency and thyroid function
  • Interpreting thyroid function tests in the context of goiter
  • Identifying associated conditions such as hypothyroidism or hyperthyroidism

Audit Risk Factors

  • Inadequate documentation of iodine deficiency
  • Failure to specify the multinodular nature of the goiter
  • Misinterpretation of thyroid function test results
  • Lack of clarity on associated symptoms or complications
