Table of Neoplasms

The code C75.1 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.

The Tabular must be reviewed for the complete diagnosis code.

Information for Patients


Pituitary Tumors

Your pituitary gland is a pea-sized gland at the base of your brain. The pituitary is the "master control gland" - it makes hormones that affect growth and the functions of other glands in the body.

Pituitary tumors are common, but often they don't cause health problems. Most people with pituitary tumors never even know they have them. The most common type of pituitary tumor produces hormones and disrupts the balance of hormones in your body. This can cause endocrine diseases such as Cushing's syndrome and hyperthyroidism.

Symptoms of pituitary tumors include

  • Headaches
  • Vision problems
  • Nausea and vomiting
  • Problems caused by the production of too many hormones

Pituitary tumors are usually curable. Treatment is often surgery to remove the tumor. Other options include medicines, radiation therapy, and chemotherapy.
