Clinical Information

• Pituitary Apoplexy-. the sudden loss of blood supply to the pituitary gland, leading to tissue necrosis and loss of function (panhypopituitarism). the most common cause is hemorrhage or infarction of a pituitary adenoma. it can also result from acute hemorrhage into sella turcica due to head trauma; intracranial hypertension; or other acute effects of central nervous system hemorrhage. clinical signs include severe headache; hypotension; bilateral visual disturbances; unconsciousness; and coma.
• Autoimmune Hypophysitis-. immune-mediated inflammation of the pituitary gland often associated with other autoimmune diseases (e.g., hashimoto disease; graves disease; and addison disease).
• Hypophysitis-. inflammation of the pituitary gland.
• Empty Sella Syndrome-. a condition when the sella turcica is not filled with pituitary tissue. the pituitary gland is either compressed, atrophied, or removed. there are two types: (1) primary empty sella is due a defect in the sella diaphragm leading to arachnoid herniation into the sellar space; (2) secondary empty sella is associated with the removal or treatment of pituitary neoplasms.
• Cerebrospinal Fluid Rhinorrhea-. discharge of cerebrospinal fluid through the nose. common etiologies include trauma, neoplasms, and prior surgery, although the condition may occur spontaneously. (otolaryngol head neck surg 1997 apr;116(4):442-9)
• Pituitary Gland-. a small, unpaired gland situated in the sella turcica. it is connected to the hypothalamus by a short stalk which is called the infundibulum.
• Pituitary Hemorrhage-. bleeding within the pituitary gland.
• Autoimmune Hypophysitis|Lymphocytic Hypophysitis-. an autoimmune condition affecting the pituitary gland, characterized by lymphocytic infiltration, commonly presenting with pituitary hormone deficiencies.
• Grade 1 Hypophysitis, CTCAE|Grade 1 Hypophysitis-. asymptomatic or mild symptoms; clinical or diagnostic observations only; intervention not indicated
• Grade 2 Hypophysitis, CTCAE|Grade 2 Hypophysitis-. moderate; minimal, local or noninvasive intervention indicated; limiting age-appropriate instrumental adl
• Grade 3 Hypophysitis, CTCAE|Grade 3 Hypophysitis-. severe or medically significant but not immediately life-threatening; hospitalization or prolongation of existing hospitalization indicated; limiting self care adl
• Grade 4 Hypophysitis, CTCAE|Grade 4 Hypophysitis-. life-threatening consequences; urgent intervention indicated
• Grade 5 Hypophysitis, CTCAE|Grade 5 Hypophysitis-. death
• Hypophysitis-. an inflammatory process in the pituitary gland.
• Hypophysitis, CTCAE|Hypophysitis-. a disorder characterized by inflammation and cellular infiltration of the pituitary gland.
• Lymphocytic Neurohypophysitis-. an autoimmune condition affecting the posterior pituitary gland, which is characterized by lymphocytic infiltration, and which often presents as diabetes insipidus.
• Cerebrospinal Fluid Rhinorrhea-. discharge of cerebrospinal fluid through the nose.

Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

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.
