Version 2021

Valid for Submission

ICD-10:D43.1
Short Description:Neoplasm of uncertain behavior of brain, infratentorial
Long Description:Neoplasm of uncertain behavior of brain, infratentorial

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)

D43.1 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of brain, infratentorial. The code D43.1 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code D43.1 might also be used to specify conditions or terms like cerebellar liponeurocytoma, low grade glioma of cerebellum, neoplasm of uncertain behavior of brain stem, neoplasm of uncertain behavior of cerebellum, neoplasm of uncertain or unknown behavior of brain, infratentorial , pilocytic astrocytoma, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: basis pedunculi ; brain NEC cerebellopontine angle ; brain NEC cerebellum NOS ; brain NEC choroid plexus ; brain NEC medulla oblongata ; brain NEC midbrain ; brain NEC peduncle ; etc

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 D43.1:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

Convert D43.1 to ICD-9 Code

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D43.1 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code D43.1 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

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.
