Thyrotoxicosis factitia without thyrotoxic crisis or storm
ICD-10 E05.40 is a billable code used to indicate a diagnosis of thyrotoxicosis factitia without thyrotoxic crisis or storm.
Thyrotoxicosis factitia is a condition characterized by excessive thyroid hormone levels due to the ingestion of exogenous thyroid hormones, often for weight loss or other perceived health benefits. Unlike other forms of hyperthyroidism, this condition does not arise from intrinsic thyroid gland dysfunction but rather from external sources. Patients may present with symptoms typical of hyperthyroidism, including weight loss, palpitations, anxiety, and heat intolerance. However, thyrotoxicosis factitia is distinct in that it does not lead to a thyrotoxic crisis or storm, which is a life-threatening exacerbation of hyperthyroid symptoms. Diagnosis typically involves a thorough history, including medication use, and laboratory tests showing elevated thyroid hormone levels (T3 and T4) with suppressed TSH levels. Management focuses on discontinuing the source of thyroid hormone and monitoring thyroid function tests to ensure levels return to normal. Understanding this condition is crucial for accurate diagnosis and treatment, as well as for appropriate coding.
Detailed patient history, including medication use and symptoms; thyroid function test results.
Patients presenting with symptoms of hyperthyroidism without a clear thyroid pathology.
Endocrinologists must ensure thorough documentation of the source of thyroid hormone to avoid misdiagnosis.
Comprehensive review of patient history and medication lists; referral notes if applicable.
Patients with unexplained weight loss or anxiety who may have self-medicated with thyroid hormones.
Primary care providers should be vigilant about asking patients about any supplements or medications taken.
Used to evaluate thyroid function in suspected thyrotoxicosis factitia.
Document the reason for the test and the patient's medication history.
Endocrinologists may require additional tests to confirm diagnosis.
The primary cause is the ingestion of exogenous thyroid hormones, often for weight loss or other perceived health benefits.
Thyrotoxicosis factitia is due to external hormone intake, while Graves' disease is an autoimmune disorder causing the thyroid to produce excess hormones.
