Code Description

ICD-10 E23.0 is a billable code used to indicate a diagnosis of hypopituitarism.

Key Diagnostic Point:

Hypopituitarism is a clinical condition characterized by the insufficient secretion of one or more of the hormones produced by the pituitary gland, which is a small gland located at the base of the brain. This condition can lead to a variety of hormonal deficiencies affecting multiple endocrine glands, including the adrenal glands, thyroid, and gonads. The causes of hypopituitarism can be diverse, including pituitary tumors, traumatic brain injury, infections, or congenital disorders. Patients may present with symptoms such as fatigue, weight loss, decreased libido, and sensitivity to cold, which are indicative of hormonal imbalances. The diagnosis is typically confirmed through hormonal assays and imaging studies, such as MRI, to assess the pituitary gland's structure. Treatment often involves hormone replacement therapy tailored to the specific deficiencies identified, which may include glucocorticoids for adrenal insufficiency, thyroid hormones, and sex hormones. Monitoring and adjusting therapy is crucial to managing this complex endocrine disorder effectively.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Variety of potential underlying causes requiring thorough investigation.
  • Multiple hormone deficiencies may complicate treatment and documentation.
  • Need for precise lab results and imaging studies to confirm diagnosis.
  • Potential for co-existing endocrine disorders that must be coded accurately.

Audit Risk Factors

  • Inadequate documentation of hormone levels and clinical symptoms.
  • Failure to document the specific cause of hypopituitarism.
  • Lack of follow-up documentation on treatment efficacy.
  • Misclassification of related endocrine disorders.

Frequently Asked Questions

What are the common symptoms of hypopituitarism?

Common symptoms include fatigue, weight gain or loss, decreased libido, sensitivity to cold, and menstrual irregularities in women.

How is hypopituitarism diagnosed?

Diagnosis typically involves a combination of clinical evaluation, hormonal assays to measure levels of pituitary hormones, and imaging studies such as MRI to assess the pituitary gland.
