Thyrotxcosis w toxic multinodular goiter w thyrotoxic crisis

This code signifies a severe and life-threatening exacerbation of hyperthyroidism, specifically in a patient with a toxic multinodular goiter. It represents a decompensated state where excessive thyroid hormone levels lead to systemic dysfunction, often involving multiple organ systems.

Use this code when documentation clearly indicates a patient with a known or newly diagnosed toxic multinodular goiter presenting with signs and symptoms consistent with thyrotoxic crisis or storm. This includes features like fever, tachycardia, altered mental status, heart failure, or gastrointestinal dysfunction attributable to extreme hyperthyroidism.

• Ensure documentation explicitly states "crisis" or "storm" in conjunction with toxic multinodular goiter.
• Do not use this code for uncomplicated thyrotoxicosis with toxic multinodular goiter without evidence of crisis.
• Code any associated complications (e.g., heart failure, delirium) separately as secondary diagnoses.
