Thyroiditis, unspecified

This code signifies inflammation of the thyroid gland without further specification regarding its cause or type. It indicates a general diagnosis of thyroiditis when the specific etiology, such as autoimmune, infectious, or drug-induced, is unknown or not documented.

This code is appropriate when the physician's documentation explicitly states "thyroiditis, unspecified" or "thyroiditis NOS." It should be used when diagnostic workup for the specific type of thyroiditis is incomplete, pending, or inconclusive, and a more precise diagnosis cannot yet be assigned.

• Avoid using this code if the documentation provides enough information to assign a more specific type of thyroiditis (e.g., Hashimoto's, subacute, acute).
• Query the provider for clarification if the documentation mentions thyroiditis but lacks specificity regarding its nature.
• This code should be considered a temporary or interim diagnosis if further investigation is planned to determine the specific cause.
