Infertility, female, of pituitary-hypothalamic origin

This code signifies female infertility stemming from dysfunction of the pituitary gland or hypothalamus. These endocrine glands are crucial for regulating ovarian function and the menstrual cycle through hormone production. Disruption in this axis leads to anovulation and subsequent inability to conceive.

Apply this code when documentation clearly indicates female infertility due to hormonal imbalances originating from the pituitary or hypothalamus. This includes conditions like hypogonadotropic hypogonadism, Kallmann syndrome, or functional hypothalamic amenorrhea. Supporting documentation should include hormone assay results (e.g., low FSH, LH, and estradiol) and imaging findings (e.g., pituitary adenoma, hypothalamic lesions) if applicable.

• Differentiate from ovarian causes of infertility (e.g., PCOS) or tubal/uterine factors.
• Ensure the physician's documentation explicitly links the infertility to a pituitary-hypothalamic etiology.
• Consider sequencing this code as the primary diagnosis when it is the definitive cause of the infertility being treated.
