Code Description

ICD-10 E01.0 is a billable code used to indicate a diagnosis of iodine-deficiency related diffuse (endemic) goiter.

Key Diagnostic Point:

Iodine-deficiency related diffuse (endemic) goiter is a condition characterized by the enlargement of the thyroid gland due to insufficient iodine intake. Iodine is an essential nutrient required for the synthesis of thyroid hormones, which play a critical role in regulating metabolism, growth, and development. In regions where iodine is scarce in the diet, the thyroid gland compensates for the lack of hormone production by enlarging, leading to a goiter. This condition is particularly prevalent in areas with low dietary iodine, often referred to as endemic regions. Patients may present with symptoms of hypothyroidism, such as fatigue, weight gain, and cold intolerance, or may remain asymptomatic despite the goiter. Diagnosis typically involves clinical examination, thyroid function tests (TFTs), and imaging studies. TFTs may reveal low levels of thyroxine (T4) and elevated thyroid-stimulating hormone (TSH) levels, indicating hypothyroidism. Treatment primarily involves iodine supplementation and monitoring of thyroid function to prevent complications associated with thyroid dysfunction.

Frequently Asked Questions

What is the primary cause of E01.0?

E01.0 is primarily caused by insufficient iodine intake, which is essential for the production of thyroid hormones.

How is E01.0 diagnosed?

Diagnosis is made through clinical examination, patient history regarding iodine intake, and thyroid function tests showing elevated TSH and low T4 levels.

What are the treatment options for E01.0?

Treatment typically involves iodine supplementation and monitoring of thyroid function to prevent complications associated with hypothyroidism.
