Code Description

ICD-10 C74.12 is a billable code used to indicate a diagnosis of malignant neoplasm of medulla of left adrenal gland.

Key Diagnostic Point:

C74.12 refers to a malignant tumor located in the medulla of the left adrenal gland, which is responsible for producing catecholamines such as epinephrine and norepinephrine. These hormones play critical roles in the body's stress response, regulating heart rate, blood pressure, and metabolism. Malignant neoplasms of the adrenal medulla can lead to excessive hormone production, resulting in symptoms such as hypertension, palpitations, and anxiety. Diagnosis typically involves imaging studies like CT or MRI, along with biochemical tests to assess hormone levels. Treatment often includes surgical resection of the tumor, and in some cases, chemotherapy or radiation therapy may be indicated. The prognosis depends on the tumor's size, stage, and the presence of metastasis. Accurate coding is essential for proper treatment planning and reimbursement.
