Thyrotxcosis w toxic sing thyroid nodule w/o thyrotxc crisis

This code describes a condition where an individual experiences hyperthyroidism due to an overactive, solitary thyroid nodule, without the acute, severe symptoms of a thyroid storm. The single nodule autonomously produces excessive thyroid hormones, leading to symptoms of thyrotoxicosis.

Use this code when documentation clearly indicates a diagnosis of hyperthyroidism caused by a single, hyperfunctioning thyroid nodule. This code is appropriate when the patient's symptoms are consistent with thyrotoxicosis but do not meet the criteria for a thyrotoxic crisis or storm.

• Differentiate from other forms of thyrotoxicosis, such as Graves' disease (E05.0-) or toxic multinodular goiter (E05.2-).
• Ensure documentation specifies "single" nodule and the absence of crisis/storm.
• If a thyrotoxic crisis or storm is present, a more specific code from the E05.11 category should be used.
