What enlarged thyroid ICD codes can I use?

If you’re looking for enlarged thyroid ICD codes, but you’re having trouble looking for one, there are no ICD-10 codes that mention enlarged thyroid in their names. Instead, they go by another term: goiter. That will pull up results! Here are six examples of ICD-10 codes for this problem:

  1. E04.9 - Nontoxic goiter, unspecified

This ICD-10 code is meant to be used on a patient confirmed to have a non-toxic goiter; however, the type of non-toxic goiter they have is not specified or known. Once the specific type of non-toxic goiter they have has been identified, it’s best to use a more specific code.

  1. E04.0 - Nontoxic diffuse goiter

This ICD-10 code is meant to be used on a patient confirmed to have a non-toxic diffuse goiter, a smooth and uniform enlargement.

  1. E04.2 - Nontoxic multinodular goiter

This ICD-10 code is meant to be used on a patient confirmed to have a non-toxic multi-nodular goiter caused by thyroid nodules in the thyroid gland.

  1. E07.1 - Dyshormogenetic goiter

This ICD-10 code is meant to be used on a patient confirmed to have a dyshormogenetic goiter, a rare kind of goiter that emerges due to hereditary defects of thyroid hormone synthesis.

  1. E04.8 - Other specified nontoxic goiter

This ICD-10 code is meant to be used on a patient confirmed to have a non-toxic goiter, precisely the kinds that don’t have specific ICD-10 codes.

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

This ICD-10 code is meant to be used on a patient confirmed to have thyrotoxicosis accompanied by toxic multi-nodular goiter and thyrotoxic crisis/storm. Thyrotoxicosis is characterized by having high amounts of thyroid hormones in the blood. The goiter here is like the one mentioned in Item 3, but it’s toxic now. A thyrotoxic storm is also present, a life-threatening problem characterized by the excessive release of thyroid hormones in a person with thyrotoxicosis.

Are these enlarged thyroid ICD codes billable?

Yes. All of those, as mentioned earlier, enlarged thyroid-related ICD-10 codes are valid and billable.

Clinical information about enlarged thyroid:

As we mentioned earlier, if you’re having trouble looking for enlarged thyroid-related ICD codes, the reason for that is that the term is different. Goiter is the term that healthcare professionals use when referring to the enlargement of the thyroid. A thyroid can become large overall or become large due to thyroid nodules. The most common cause for the emergence of goiters is iodine deficiency, so, as a non-medical precaution or lifestyle suggestion, it’s good to ensure that your diet has a good amount of iodine.

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
  • Mass of thyroid gland
  • Nodular goiter
  • Sporadic goiter
  • Substernal goiter
  • Colloid goiter
  • Diffuse goiter
  • Diffuse thyroid goiter without thyrotoxicosis
  • Simple goiter
  • Multinodular goiter
  • Multinodular goiter, cystic kidney, polydactyly syndrome
  • Non-toxic multinodular goiter
  • Non-toxic nodular goiter

Commonly asked questions

Will there ever be ICD codes that specifically mention enlarged thyroid in their names?

Most likely not, given that the term goiter refers to it.

Besides iodine deficiency and thyroid nodules, what other problems cause goiters to emerge?

Other causes include hypothyroidism, hyperthyroidism, thyroid cancer, Hashimoto’s disease, pregnancy, inflammations, and even Grave’s disease.

How are goiters treated?

Some can be left well alone, and they will go away alone. Some may require specific medications, and the drug will depend on what caused the goiter to emerge in the first place. If the goiter is significantly impacting a person’s breathing, surgery is the best bet. Depending on the treatment, the patient may require thyroid hormone replacement therapy down the line.
