Nontoxic goiter, unspecified

This code represents an enlargement of the thyroid gland (goiter) that is not associated with hyperthyroidism or hypothyroidism, and where the specific cause of the goiter is unknown or not documented. It indicates a benign, non-inflammatory thyroid enlargement without functional disturbance.

Use this code when documentation indicates a goiter without specifying its toxic nature (e.g., "simple goiter," "diffuse goiter," "nodular goiter") and without evidence of thyroid hormone overproduction or underproduction. This code is appropriate when the physician has not identified a more specific type of goiter.

• Avoid using this code if the documentation specifies a toxic goiter (e.g., Graves' disease) or a goiter with hypothyroidism.
• Always seek clarification from the provider if the documentation mentions a goiter but lacks information regarding its toxicity or specific type.
• Do not use this code if a more specific goiter diagnosis, such as a multinodular goiter with thyrotoxicosis, is documented.
