Version 2021

Not Valid for Submission

ICD-10:D35
Short Description:Benign neoplasm of other and unspecified endocrine glands
Long Description:Benign neoplasm of other and unspecified endocrine glands

Code Classification

  • Neoplasms (C00–D48)
    • Benign neoplasms, except benign neuroendocrine tumors (D10-D36)
      • Benign neoplasm of other and unspecified endocrine glands (D35)

D35 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of benign neoplasm of other and unspecified endocrine glands. 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.

Unspecified diagnosis codes like D35 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding for Benign neoplasm of other and unspecified endocrine glands

Non-specific codes like D35 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for benign neoplasm of other and unspecified endocrine glands:

  • NON-BILLABLE CODE - D35.0 for Benign neoplasm of adrenal gland
  • BILLABLE CODE - Use D35.00 for Benign neoplasm of unspecified adrenal gland
  • BILLABLE CODE - Use D35.01 for Benign neoplasm of right adrenal gland
  • BILLABLE CODE - Use D35.02 for Benign neoplasm of left adrenal gland
  • BILLABLE CODE - Use D35.1 for Benign neoplasm of parathyroid gland
  • BILLABLE CODE - Use D35.2 for Benign neoplasm of pituitary gland
  • BILLABLE CODE - Use D35.3 for Benign neoplasm of craniopharyngeal duct
  • BILLABLE CODE - Use D35.4 for Benign neoplasm of pineal gland
  • BILLABLE CODE - Use D35.5 for Benign neoplasm of carotid body
  • BILLABLE CODE - Use D35.6 for Benign neoplasm of aortic body and other paraganglia
  • BILLABLE CODE - Use D35.7 for Benign neoplasm of other specified endocrine glands
  • BILLABLE CODE - Use D35.9 for Benign neoplasm of endocrine gland, unspecified

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D35:


Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.

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.

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.

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.
