2022 ICD-10-CM Code C75.1

Malignant neoplasm of pituitary gland

Version 2021

Valid for Submission

ICD-10:C75.1
Short Description:Malignant neoplasm of pituitary gland
Long Description:Malignant neoplasm of pituitary gland

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of thyroid and other endocrine glands (C73-C75)
      • Malignant neoplasm of endo glands and related structures (C75)

C75.1 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of pituitary gland. The code C75.1 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 C75.1 might also be used to specify conditions or terms like carcinoma of brain, carcinoma of hypothalamus, ependymoma, ependymoma of brain, ependymoma of central nervous system , ependymoma of cerebrum, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: fossa (of) pituitary ; hypophysis ; intrasellar ; pituitary (body) (fossa) (gland) (lobe) ; Rathke's pouch ; sella turcica ; etc

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 C75.1 are found in the index:

Approximate Synonyms

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C75.1 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 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.

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

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