2024 ICD-10-CM Diagnosis Code D44.5

Approximate Synonyms

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

• Neoplasm of uncertain behavior of endocrine glands and nervous system
• Neoplasm of uncertain behavior of endocrine glands and nervous system
• Neoplasm of uncertain behavior of endocrine glands and nervous system
• Neoplasm of uncertain behavior of pineal gland
• Pinealoma
• Pineocytoma

Clinical Information

• Pinealoma

  neoplasms which originate from pineal parenchymal cells that tend to enlarge the gland and be locally invasive. the two major forms are pineocytoma and the more malignant pineoblastoma. pineocytomas have moderate cellularity and tend to form rosette patterns. pineoblastomas are highly cellular tumors containing small, poorly differentiated cells. these tumors occasionally seed the neuroaxis or cause obstructive hydrocephalus or parinaud's syndrome. germinoma; carcinoma, embryonal; glioma; and other neoplasms may arise in the pineal region with germinoma being the most common pineal region tumor.

Table of Neoplasms

This code is referenced 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.

Filter table of neoplasms:

»Neoplasm, neoplastic   »pineal (body) (gland)	C75.3	C79.89	D09.3	D35.4	D44.5	D49.7

Brain Diseases

Your brain is the control center of your body. It controls your thoughts, memory, speech, and movement. It regulates the function of many organs. It's part of your nervous system, which also includes your spinal cord and peripheral nerves. The nervous system sends signals between your brain and the rest of the body. Your nerves take in information from your senses and send it to the brain to be processed. Your brain and nerves also communicate to help you move and to control your body's functions.

When the brain is healthy, it works quickly and automatically. But when you have a brain disease, it may affect how well you can function and do your daily activities. Some common brain diseases include:

• Brain tumors, which can press on nerves and affect brain function.
• Degenerative nerve diseases, which can affect many of your body's activities, such as balance, movement, talking, breathing, and heart function. Types include Alzheimer's disease and Parkinson's disease.
• Encephalitis (inflammation in the brain), which can lead to problems such as vision loss, weakness, and paralysis.
• Genetic brain disorders, which are caused by changes in genes (also called variants or mutations). These disorders can affect the development and function of the brain.
• Strokes, which can cause a loss of brain cells and can affect your ability to think clearly.
• Traumatic brain injuries (TBIs), which can affect brain function. They may range from mild to severe. The effects of a TBI may be temporary or permanent.

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 therapies such as physical, occupational, and speech therapies, may cure the disease or improve the symptoms.

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:

• Growth and development
• Metabolism - digestion, elimination, breathing, blood circulation and maintaining body temperature
• Sexual function
• Reproduction
• Mood

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.
