Nontoxic multinodular goiter

This code represents an enlargement of the thyroid gland characterized by multiple nodules, which is not associated with hyperthyroidism or hypothyroidism. The goiter is palpable and visible, but thyroid function tests typically remain within normal limits.

Use this code when documentation indicates a patient has a multinodular goiter without evidence of thyroid hormone overproduction or underproduction. This diagnosis is often made incidentally during physical examination or imaging studies.

• Ensure documentation explicitly states "nontoxic" or "euthyroid" in conjunction with "multinodular goiter."
• Do not use this code if the goiter is associated with hyperthyroidism (e.g., toxic multinodular goiter) or hypothyroidism.
• Consider additional codes for any associated symptoms or complications, if documented.
