Thyrotoxicosis w diffuse goiter w/o thyrotoxic crisis

This code signifies hyperthyroidism characterized by an enlarged thyroid gland (goiter) that is uniformly affected, without the presence of a severe, life-threatening exacerbation of hyperthyroidism known as a thyrotoxic crisis or storm. It represents a common form of hyperthyroidism, often associated with Graves' disease, where the thyroid gland overproduces hormones.

Apply this code when documentation indicates a patient has symptoms and lab findings consistent with hyperthyroidism, a diffusely enlarged thyroid gland on physical exam or imaging, and no mention of a thyrotoxic crisis. This code is appropriate for initial diagnoses and ongoing management of uncomplicated diffuse toxic goiter.

• Ensure documentation explicitly states "diffuse goiter" and rules out a thyrotoxic crisis.
• Distinguish from nodular goiter (E05.2-) or other forms of thyrotoxicosis (E05.1-, E05.3-, E05.4-).
• If Graves' disease is specifically documented as the cause, an additional code for Graves' disease (E05.01) may be required depending on payer guidelines.
