Other hypothyroidism
Chapter 4:Endocrine, nutritional and metabolic diseases
ICD-10 E03 is a billable code used to indicate a diagnosis of other hypothyroidism.
Other hypothyroidism (E03) refers to a group of conditions characterized by insufficient production of thyroid hormones, which can lead to a variety of metabolic and physiological disturbances. This condition can arise from various etiologies, including autoimmune disorders such as Hashimoto's thyroiditis, congenital hypothyroidism, or secondary causes related to pituitary dysfunction. Patients may present with symptoms such as fatigue, weight gain, cold intolerance, dry skin, and hair loss. Diagnosis typically involves thyroid function tests, including serum levels of Thyroid Stimulating Hormone (TSH) and free thyroxine (FT4). An elevated TSH level with low FT4 indicates primary hypothyroidism, while low TSH with low FT4 suggests secondary causes. Iodine deficiency is a significant contributor to hypothyroidism globally, particularly in regions where iodine supplementation is not prevalent. Treatment usually involves thyroid hormone replacement therapy, with levothyroxine being the most commonly prescribed medication. Regular monitoring of thyroid function tests is essential to ensure appropriate dosing and management of the condition.
Thorough documentation of patient history, physical examination findings, and laboratory results related to thyroid function.
Patients presenting with fatigue, weight changes, or other symptoms suggestive of thyroid dysfunction.
Endocrinologists must ensure that all relevant lab tests are documented to support the diagnosis and treatment plan.
Complete patient history, including family history of thyroid disease, and documentation of symptoms and lab results.
Routine screening for hypothyroidism in patients with risk factors or presenting symptoms.
Primary care providers should be aware of the need for regular monitoring and follow-up of thyroid function tests.
Used to evaluate thyroid function in patients suspected of hypothyroidism.
Document the reason for the test and any relevant clinical findings.
Endocrinologists may require more frequent testing based on patient history.
Common symptoms include fatigue, weight gain, cold intolerance, dry skin, hair loss, and depression. Patients may also experience muscle weakness and joint pain.
