Enlarged Thyroid ICD-10-CM Codes

What enlarged thyroid ICD codes can I use?

The thyroid is a butterfly-shaped endocrine gland located in the neck that plays a vital role in regulating metabolism by producing thyroid hormones. When this gland becomes abnormally enlarged, the condition is known as a goiter, or enlarged thyroid.

This condition can result from various factors, including iodine deficiency, thyroid nodules, thyroid disorders, and thyroid cancer. Accurate coding is essential for effective diagnosis, treatment planning, and medical billing.

If you're searching for ICD-10 codes related to an enlarged thyroid or thyroid disease, you may not find any codes using that exact term. Instead, the condition is classified under the term "goiter" in the ICD-10-CM coding system. Searching for "goiter" will yield the relevant diagnostic codes.

Here are six commonly used examples:

E04.9 - Nontoxic goiter, unspecified

This ICD-10 code is meant to be used on a patient confirmed to have a non-toxic goiter, but the specific type (e.g., diffuse or multinodular) isn't specified in the medical documentation. It's appropriate for general cases of thyroid enlargement without a specified cause.

E04.0 - Nontoxic diffuse goiter

This code applies to a uniform enlargement of the thyroid gland without signs of hyperthyroidism or hypothyroidism. It's often linked to iodine deficiency and may present with difficulty swallowing or breathing.

E04.2 - Nontoxic multinodular goiter

This code is used for cases where multiple nodules are present within the thyroid gland without hyperthyroidism. It's common in regions with iodine deficiency and may lead to noticeable neck swelling.

E07.1 - Dyshormogenetic goiter

This code represents a rare form of goiter resulting from hereditary defects in thyroid hormone synthesis. It's a congenital condition, meaning the patient is born with it.

E04.8 - Other specified nontoxic goiter

This code covers other specific types of nontoxic goiters not classified elsewhere, including those related to Hashimoto's disease or other thyroid disorders. It's used when the goiter has specific characteristics that don't fit into other categories.

E05.21 - Thyrotoxicosis with toxic multinodular goiter with a thyrotoxic crisis or storm

This code is appropriate for patients diagnosed with thyrotoxicosis accompanied by a toxic multinodular goiter and a thyrotoxic crisis or storm. Thyrotoxicosis is characterized by elevated levels of thyroid hormones in the blood, and a thyrotoxic crisis is a life-threatening condition requiring immediate medical attention.

Are these enlarged thyroid ICD codes billable?

Yes, all the ICD-10-CM codes listed for goiter, the clinical term used for an enlarged thyroid, are billable. Each of the following codes is valid for claim submission and should be selected based on the specific diagnosis.

Clinical information about enlarged thyroid

Goiter is the term that healthcare professionals use when referring to the enlargement of the thyroid. A thyroid gland can become large overall or become large due to thyroid nodules. One of the most common causes of thyroid enlargement is an iodine deficiency related goiter, particularly in regions where iodine intake is low.

Goiters may or may not prevent the thyroid from performing its function. It also may or may not affect the amount of thyroid hormones produced. We mentioned “may or may not” twice because some goiters are small enough that they don't cause any problems.

A goiter becomes concerning if it grows too quickly, makes breathing difficult for the person who has it, and if there are noticeable impacts on the thyroid function. If the goiter is large and obstructive, those who have it may experience the following symptoms:

• They will have trouble breathing.
• They will have a difficult time swallowing food.
• Their voice will be scratchy and husky.
• They might start coughing.

Synonyms include

• Goiter
• Goiter due to thyroiditis
• Nodular goiter
• Sporadic goiter
• Substernal goiter
• Colloid goiter
• Diffuse goiter
• Diffuse thyroid goiter without thyrotoxicosis
• Simple goiter
• Multinodular goiter
• Non-toxic multinodular goiter
• Non-toxic nodular goiter
