ICD 10 E05.91 describes a medical condition characterized by the excessive secretion of thyroid hormones in the body due to an overactive thyroid gland, which can lead to a life-threatening state known as thyrotoxic crisis or storm, causing extreme symptoms such as high fever and brain damage if left untreated, and although the provider does not specify the type of thyrotoxicosis, the patient exhibits symptoms of thyrotoxic crisis or storm.

Official Description Of E05.91

The ICD 10 CM book defines ICD 10 code E05.91 as:

Thyrotoxicosis, unspecified with thyrotoxic crisis or storm
Parent Code Notes: E05

Clinical Information

The diagnosis describes by the ICD 10 CM E05.91 code pertains to patients who experience thyrotoxicosis with thyrotoxic crisis or storm. This medical condition can be life-threatening and requires immediate medical attention. Patients experiencing this crisis typically exhibit symptoms such as fever, pain, anxiety, nervousness, increased heart rate, fatigue, muscle weakness, intolerance to heat, excessive sweating, tremors, weight loss, diarrhea, abdominal pain, respiratory problems, mental abnormalities, and coma.

To diagnose thyrotoxicosis, healthcare providers typically look at the patient’s medical history, physical exam, and signs and symptoms. These findings are then supported by laboratory tests such as a thyroid function test, which measures TSH, T4, T3, and thyroglobulin. Other laboratory tests include ELISA and FNA biopsy of the thyroid tissue. Imaging tests such as scintigraphy, CT scan, and MRI can also be utilized to assist with diagnosis.

Treatment for thyrotoxic crisis or storm involves a combination of symptomatic relief and medication to reduce thyroid hormone levels. Antithyroid drugs such as propylthiouracil and methimazole can be used to block the production of thyroid hormones. Radioactive iodine can also be administered as a treatment option. In some cases, surgery to remove the thyroid gland (thyroidectomy) might be necessary to manage the condition effectively.

It is crucial to manage this medical condition promptly since thyrotoxicosis can lead to life-threatening complications. It is essential to follow the treatment plan established by the healthcare provider and attend follow-up appointments to manage the symptoms and ensure that the patient’s condition improves.

In conclusion, the ICD 10 CM E05.91 code identifies patients with thyrotoxicosis and thyrotoxic crisis or storm. The diagnosis involves analyzing the patient’s medical history, conducting physical exams, and performing laboratory and imaging tests. Treatment options include antithyroid drugs, radioactive iodine, or in extreme cases, thyroidectomy. It is critical to act quickly to help reduce the risk of potential life-threatening complications, and following up with healthcare providers is essential to managing symptoms effectively.
