Code Classification

  • Neoplasms
    (C00–D49)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes
      (D37-D48)
      • Neoplasm of uncertain behavior of endocrine glands
        (D44)

D44 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of neoplasm of uncertain behavior of endocrine glands. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Neoplasm of uncertain behavior of endocrine glands

Non-specific codes like D44 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for neoplasm of uncertain behavior of endocrine glands:

  • Use D44.0 for Neoplasm of uncertain behavior of thyroid gland - BILLABLE CODE

  • D44.1 for Neoplasm of uncertain behavior of adrenal gland - NON-BILLABLE CODE

  • Use D44.10 for Neoplasm of uncertain behavior of unspecified adrenal gland - BILLABLE CODE

  • Use D44.11 for Neoplasm of uncertain behavior of right adrenal gland - BILLABLE CODE

  • Use D44.12 for Neoplasm of uncertain behavior of left adrenal gland - BILLABLE CODE

  • Use D44.2 for Neoplasm of uncertain behavior of parathyroid gland - BILLABLE CODE

  • Use D44.3 for Neoplasm of uncertain behavior of pituitary gland - BILLABLE CODE

  • Use D44.4 for Neoplasm of uncertain behavior of craniopharyngeal duct - BILLABLE CODE

  • Use D44.5 for Neoplasm of uncertain behavior of pineal gland - BILLABLE CODE

  • Use D44.6 for Neoplasm of uncertain behavior of carotid body - BILLABLE CODE

  • Use D44.7 for Neoplasm of uncertain behavior of aortic body and other paraganglia - BILLABLE CODE

  • Use D44.9 for Neoplasm of uncertain behavior of unspecified endocrine gland - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • multiple endocrine adenomatosis E31.2
  • multiple endocrine neoplasia E31.2
  • neoplasm of uncertain behavior of endocrine pancreas D37.8
  • neoplasm of uncertain behavior of ovary D39.1
  • neoplasm of uncertain behavior of testis D40.1
  • neoplasm of uncertain behavior of thymus D38.4

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Endocrine Diseases

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include:

  • Growth and development
  • Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature
  • Sexual function
  • Reproduction
  • Mood

If your hormone levels are too high or too low, you may have a hormone disorder. Hormone diseases also occur if your body does not respond to hormones the way it is supposed to. Stress, infection and changes in your blood's fluid and electrolyte balance can also influence hormone levels.

In the United States, the most common endocrine disease is diabetes. There are many others. They are usually treated by controlling how much hormone your body makes. Hormone supplements can help if the problem is too little of a hormone.
