What thyroid nodules ICD codes can I use?
There are only a few thyroid nodules ICD codes you can pick from. Here they are:
- E04.1 - Nontoxic single thyroid nodule
This ICD-10 code is meant to be used on a person confirmed to have a single thyroid nodule, and the nodule isn’t toxic. The nodule shouldn’t cease the functioning of the thyroid. The only time it’ll affect the functioning of the thyroid is if the person has a severe iodine deficiency.
- E05.10 - Thyrotoxicosis with toxic single thyroid nodule without thyrotoxic crisis or storm
This ICD-10 code is meant to be used on a patient confirmed to have thyrotoxicosis, which is a condition characterized by having too many thyroid hormones in the body in general. It is also confirmed that they have a single toxic single thyroid nodule. This means that the thyroid nodule releases excessive thyroid hormones. Despite this, the patient doesn’t have a thyrotoxic crisis/storm, a rare albeit life-threatening problem characterized by the thyroid releasing excessive amounts of thyroid hormones in a short time.
- E05.11 - Thyrotoxicosis with toxic single thyroid nodule with thyrotoxic crisis or storm
This is the same as Item 2, but this time, the patient is also dealing with thyrotoxic crisis/storm.
- E05.30 - Thyrotoxicosis from ectopic thyroid tissue without thyrotoxic crisis or storm
This ICD-10 code is meant to be used on a patient confirmed to have thyrotoxicosis due to an ectopic thyroid tissue, which is a thyroid tissue located in unusual areas/places in the body where it shouldn’t be. Just like with Item 2, the patient has no thyrotoxic crisis/storm.
- E05.31 - Thyrotoxicosis from ectopic thyroid tissue with thyrotoxic crisis or storm
This is the same as Item 4, but this time, the patient is also dealing with thryotoxic crisis/storm.
Which of these thyroid nodules ICD codes are billable?
All five of these thyroid nodule-related ICD-10 codes we’ve listed above are valid and billable.
Clinical information about thyroid nodules:
Thyroid nodules are lumps that form in the thyroid gland. Most of the time, these lumps are benign, but there are rare instances of these nodules being cancerous.
A person who has thyroid nodules will experience the following symptoms:
- Their thyroid gland will be enlarged
- They will have trouble swallowing food
- They will have trouble breathing
- They will have trouble sleeping
- They will have pain in the front of their neck
- They will have palpitations
- Diarrhea
- They will have noticeable changes in their voice
So far, it hasn’t been determined why these nodules form. These nodules can come in the form of inflammatory nodules, multinodular thyroid goiter, colloid nodules, cysts, toxic nodules, or even thyroid cancer.
Synonyms include:
- Calcifying cyst of thyroid
- Cyst of thyroid
- Dominant nodule of thyroid
- Hyperplastic thyroid nodule
- Non-toxic uninodular goiter
- Toxic nodular goiter
- Toxic uninodular goiter
Commonly asked questions
We left out one because it isn’t valid and billable: E05.1 - Thyrotoxicosis with toxic single thyroid nodule. It’s not as specific as the ones we’ve listed, so best to use the ones mentioned above instead.
Professionals will conduct thyroid blood tests, thyroid ultrasounds, thyroid scans, and/or biopsies.
The course of action for nodules depends on whether they are benign or not. In the case of benign nodules, some professionals may recommend regular monitoring over time, while others may opt for administering radioactive iodine treatment. However, if the nodules are determined to be cancerous, surgery remains the most effective and advisable approach.
