The code is not specific and is NOT valid for the year 2022 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.

  • BILLABLE CODE - Use D44.0 for Neoplasm of uncertain behavior of thyroid gland
  • NON-BILLABLE CODE - D44.1 for Neoplasm of uncertain behavior of adrenal gland
  • 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

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!"

Information for Patients


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

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.
