What is Hypothyroidism ICD 10?

Hypothyroidism ICD 10 (E03.9), also known as underactive thyroid, which occurs when the thyroid gland in the body does not produce the enough thyroid hormone. This hormone is crucial for regulating the body's metabolism. In the early stages, hypothyroidism may not cause noticeable symptoms, but untreated, it can lead to severe health issues, such as high cholesterol and heart problems.

Why is Hypothyroidism Unspecified ICD 10 Happening?

Hypothyroidism unspecified ICD 10 (Code: E03.9) can be caused by primary and secondary causes:

Primary Causes:
Conditions directly affecting the thyroid gland, such as Hashimoto’s thyroiditis or iodine deficiency, which impair its ability to produce thyroid hormones.
Secondary Causes:
Issues with the pituitary gland or hypothalamus that affect hormone regulation and thyroid function.

Treatment Options for Hypothyroidism ICD 10

The primary treatment is taking levothyroxine, a synthetic thyroid hormone, to normalize hormone levels.

Diagnostics for Hypothyroidism ICD 10

Thyroid Stimulating Hormone (TSH) Test:
Blood test measuring TSH levels, which helps diagnose hypothyroidism by indicating if the thyroid is underactive.

Symptoms for Hypothyroidism ICD 10

Tiredness and fatigue
Increased sensitivity to cold
Constipation
Dry skin and coarse hair
Weight gain and puffy face
Hoarse voice and slowed heart rate
Muscle weakness, aches, and stiffness
Heavy or irregular menstrual cycles
