ICD-10-CM Code D49.6

Neoplasm of unspecified behavior of brain

Version 2020 Billable Code Neoplasm Unspecified Behavior

Valid for Submission

D49.6 is a billable code used to specify a medical diagnosis of neoplasm of unspecified behavior of brain. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D49.6 might also be used to specify conditions or terms like cerebellopontine angle tumor, cerebral degeneration due to neoplastic disease, epilepsy due to intracranial tumor, germ cell tumor of the brain, intracranial tumor, neoplasm of brain, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: basal ganglia ; basis pedunculi ; brain NEC ; brain NEC basal ganglia ; brain NEC cerebellopontine angle ; brain NEC cerebellum NOS ; brain NEC cerebrum ; 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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code D49.6:

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.
  • neoplasm of unspecified behavior of cerebral meninges D49.7
  • neoplasm of unspecified behavior of cranial nerves D49.7

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code D49.6 are found in the index:

Table of Neoplasms

The code D49.6 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.
