2024 ICD-10-CM Diagnosis Code E24.1

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

• ACTH-dependent Cushing's syndrome
• Nelson syndrome

Clinical Information

• Nelson Syndrome

  a syndrome characterized by hyperpigmentation, enlarging pituitary mass, visual defects secondary to compression of the optic chiasm, and elevated serum acth. it is caused by the expansion of an underlying acth-secreting pituitary adenoma that grows in the absence of feedback inhibition by adrenal corticosteroids, usually after adrenalectomy.

• Nelson Syndrome

  a syndrome that develops following bilateral adrenalectomy for cushing syndrome. the signs and symptoms result from the presence of an adenocorticotropin-secreting pituitary gland adenoma, and include enlargement of the sella turcica and pressure on the adjacent structures, and skin hyperpigmentation.

E24.1 is grouped with 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.

Convert E24.1 to ICD-9-CM

• ICD-9-CM Code: 253.8 - Pituitary disorder NEC
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

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.
