Neoplasms
(C00–D49)
- Benign neoplasms, except benign neuroendocrine tumors
  (D10-D36)
  - Benign neoplasm of thyroid gland
    (D34)

D34 is a billable diagnosis code used to specify a medical diagnosis of benign neoplasm of thyroid gland. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic thyroglossal duct or Neoplasm, neoplastic thyroid (gland) .

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Benign neoplasm of thyroglossal duct
Benign neoplasm of thyroid gland
Follicular adenoma of ectopic thyroid tissue
Follicular neoplasm of thyroid
Follicular neoplasm of thyroid
Follicular neoplasm of thyroid
Neoplasm of thyroglossal duct
Thyroid adenoma
Thyroid follicular adenoma
Thyrotoxicosis due to toxic thyroid adenoma
Toxic thyroid adenoma

Clinical Classification

Clinical Category is Benign neoplasms
CCSR Category Code: NEO073
Inpatient Default CCSR: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

Table of Neoplasms

This code is referenced 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.

Patient Education

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 small, butterfly-shaped gland in the front of your neck. It makes hormones that control the way the body uses energy. These hormones affect nearly every organ in your body and control many of your body's most important functions. For example, they affect your breathing, heart rate, weight, digestion, and moods.

Thyroid diseases cause your thyroid to make either too much or too little of the hormones. Some of the different thyroid diseases include:

Goiter, an enlargement of the thyroid gland
Hyperthyroidism, which happens when your thyroid gland makes more thyroid hormones than your body needs
Hypothyroidism, which happens 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, your health care provider may use a medical history, physical exam, and thyroid tests. In some cases, your provider may also do a biopsy.

Treatment depends on the problem, how severe it is, and what your symptoms are. Possible treatments may include medicines, radioiodine therapy, or thyroid surgery.
