About E05.2
E05.2 is the ICD-10-CM diagnosis code for thyrotoxicosis with toxic multinodular goiter. It belongs to category E05 (thyrotoxicosis [hyperthyroidism]), block E00-E07 (disorders of thyroid gland) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.
Within E05 (thyrotoxicosis [hyperthyroidism]), E05.2 is specifically for thyrotoxicosis with toxic multinodular goiter. Related codes cover thyrotoxicosis with diffuse goiter (E05.0), thyrotoxicosis with toxic single thyroid nodule (E05.1), thyrotoxicosis from ectopic thyroid tissue (E05.3), thyrotoxicosis factitia (E05.4), other thyrotoxicosis (E05.8) and thyrotoxicosis, unspecified (E05.9).
To report this condition, pick the subcode that matches the documentation: E05.20 (without thyrotoxic crisis or storm) and E05.21 (with thyrotoxic crisis or storm).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
