D44.0 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior 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:
- Neoplasm of thyroglossal duct
- Neoplasm of uncertain behavior of thyroglossal duct
- Neoplasm of uncertain behavior of thyroid gland
Clinical Classification
Clinical Category is Neoplasms of unspecified nature or uncertain behavior
- CCSR Category Code: NEO072
- 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.

Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
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
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.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
