ICD-10-CM Code D35.2

Benign neoplasm of pituitary gland

Version 2020 Billable Code Neoplasm Benign

Valid for Submission

D35.2 is a billable code used to specify a medical diagnosis of benign neoplasm of pituitary gland. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code D35.2 might also be used to specify conditions or terms like acth-dependent cushing's syndrome, benign neoplasm of craniopharyngeal duct, benign neoplasm of pituitary gland, benign neoplasm of pituitary gland and craniopharyngeal duct, corticotroph adenoma, familial isolated pituitary adenoma, etc

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

Diagnostic Related Groups

The ICD-10 code D35.2 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2020 through 09/30/2020.

  • 644 - ENDOCRINE DISORDERS WITH CC
  • 645 - ENDOCRINE DISORDERS WITHOUT CC/MCC

Table of Neoplasms

The code D35.2 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


Benign Tumors

Tumors are abnormal growths in your body. They can be either benign or malignant. Benign tumors aren't cancer. Malignant ones are. Benign tumors grow only in one place. They cannot spread or invade other parts of your body. Even so, they can be dangerous if they press on vital organs, such as your brain.

Tumors are made up of extra cells. Normally, cells grow and divide to form new cells as your body needs them. When cells grow old, they die, and new cells take their place. Sometimes, this process goes wrong. New cells form when your body does not need them, and old cells do not die when they should. These extra cells can divide without stopping and may form tumor.

Treatment often involves surgery. Benign tumors usually don't grow back.

Pituitary Disorders

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.

With pituitary disorders, you often have too much or too little of one of your hormones. Injuries can cause pituitary disorders, but the most common cause is a pituitary tumor.
