ICD-10:D43
Short Description:Neoplasm of uncertain behavior of brain and cnsl
Long Description:Neoplasm of uncertain behavior of brain and central nervous system

Code Classification

  • Neoplasms (C00–D48)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
      • Neoplasm of uncertain behavior of brain and cnsl (D43)

D43 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 brain and 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 Neoplasm of uncertain behavior of brain and cnsl

Non-specific codes like D43 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 neoplasm of uncertain behavior of brain and cnsl:

  • BILLABLE CODE - Use D43.0 for Neoplasm of uncertain behavior of brain, supratentorial
  • BILLABLE CODE - Use D43.1 for Neoplasm of uncertain behavior of brain, infratentorial
  • BILLABLE CODE - Use D43.2 for Neoplasm of uncertain behavior of brain, unspecified
  • BILLABLE CODE - Use D43.3 for Neoplasm of uncertain behavior of cranial nerves
  • BILLABLE CODE - Use D43.4 for Neoplasm of uncertain behavior of spinal cord
  • BILLABLE CODE - Use D43.8 for Neoplasm of uncertain behavior of other specified parts of central nervous system
  • BILLABLE CODE - Use D43.9 for Neoplasm of uncertain behavior 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 D43:


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


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.
