2022 ICD-10-CM Code D33

Benign neoplasm of brain and other parts of central nervous system

Version 2021

Not Valid for Submission

ICD-10:D33
Short Description:Benign neoplasm of brain and oth prt central nervous system
Long Description:Benign neoplasm of brain and other parts of central nervous system

Code Classification

  • Neoplasms (C00–D48)
    • Benign neoplasms, except benign neuroendocrine tumors (D10-D36)
      • Benign neoplasm of brain and oth prt central nervous system (D33)

D33 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 brain and other parts of central nervous system. 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.

Specific Coding for Benign neoplasm of brain and oth prt central nervous system

Non-specific codes like D33 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 brain and oth prt central nervous system:

  • BILLABLE CODE - Use D33.0 for Benign neoplasm of brain, supratentorial
  • BILLABLE CODE - Use D33.1 for Benign neoplasm of brain, infratentorial
  • BILLABLE CODE - Use D33.2 for Benign neoplasm of brain, unspecified
  • BILLABLE CODE - Use D33.3 for Benign neoplasm of cranial nerves
  • BILLABLE CODE - Use D33.4 for Benign neoplasm of spinal cord
  • BILLABLE CODE - Use D33.7 for Benign neoplasm of other specified parts of central nervous system
  • BILLABLE CODE - Use D33.9 for Benign neoplasm of central nervous system, 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 D33:


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.

Brain Diseases

The brain is the control center of the body. It controls thoughts, memory, speech, and movement. It regulates the function of many organs. When the brain is healthy, it works quickly and automatically. However, when problems occur, the results can be devastating.

Inflammation in the brain can lead to problems such as vision loss, weakness and paralysis. Loss of brain cells, which happens if you suffer a stroke, can affect your ability to think clearly. Brain tumors can also press on nerves and affect brain function. Some brain diseases are genetic. And we do not know what causes some brain diseases, such as Alzheimer's disease.

The symptoms of brain diseases vary widely depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or physical therapy can correct the source of the problem or improve symptoms.
