What is the correct code for Nelson's syndrome?

Nelson's syndrome is a condition characterized by the development of a pituitary adenoma in patients with adrenal insufficiency resulting from the surgical removal of adrenal glands. The correct code for Nelson's syndrome is E24.1, which specifically designates this condition within the International Classification of Diseases (ICD-10).

Understanding coding requires knowledge of the specific conditions and their associated codes. E24.1 pertains to Nelson's syndrome, making it the precise identifier for this disorder. The other codes represent different conditions: E03.5 refers to hypothyroidism due to a previous thyroid surgery, Z79.4 refers to long-term use of exogenous hormones, and F50.2 covers a type of eating disorder known as atypical anorexia nervosa. None of these accurately reflects Nelson's syndrome. Thus, E24.1 is the appropriate code for this specific endocrine-related condition.
