ICD-10-CM Code D34

Benign neoplasm of thyroid gland

Version 2020 Billable Code Neoplasm Benign

Valid for Submission

D34 is a billable code used to specify a medical diagnosis of benign neoplasm of thyroid gland. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D34 might also be used to specify conditions or terms like benign neoplasm of thyroglossal duct, benign neoplasm of thyroid gland, follicular adenoma of ectopic thyroid tissue, follicular neoplasm of thyroid, neoplasm of thyroglossal duct, thyroid adenoma, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: thyroglossal duct or thyroid (gland) .

Table of Neoplasms

The code D34 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

Thyroid Diseases

Your thyroid is a butterfly-shaped gland in your neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid hormones control the rate of many activities in your body. These include how fast you burn calories and how fast your heart beats. All of these activities are your body's metabolism.

Thyroid problems include

  • Goiter - enlargement of the thyroid gland
  • Hyperthyroidism - when your thyroid gland makes more thyroid hormones than your body needs
  • Hypothyroidism - when your thyroid gland does not make enough thyroid hormones
  • Thyroid cancer
  • Thyroid nodules - lumps in the thyroid gland
  • Thyroiditis - swelling of the thyroid

To diagnose thyroid diseases, doctors use a medical history, physical exam, and thyroid tests. They sometimes also use a biopsy. Treatment depends on the problem, but may include medicines, radioiodine therapy, or thyroid surgery.
