ICD Code E05.20

ICD code E05.20 is thyrotoxicosis with toxic multinodular goiter without thyrotoxic crisis or storm. This means the patient has an overactive thyroid caused by multiple overactive nodules in the thyroid gland, but is not experiencing a severe, life-threatening episode (thyrotoxic crisis or storm).

1. Presence of thyrotoxicosis (clinical or laboratory evidence of excess thyroid hormone)

2. Diagnosis of toxic multinodular goiter (enlarged thyroid gland with multiple nodules producing excess thyroid hormone)

3. Absence of thyrotoxic crisis or thyroid storm (no acute, life-threatening exacerbation of thyrotoxicosis)

4. Symptoms may include weight loss, heat intolerance, palpitations, tremor, anxiety, increased appetite, and hyperactivity

5. Physical findings may include goiter with palpable nodules, tachycardia, and possible atrial fibrillation

6. Laboratory findings typically show suppressed TSH and elevated free T4 and/or T3
