2025 ICD-10-CM code E25.0

Congenital adrenogenital disorders associated with enzyme deficiency. This includes conditions like congenital adrenal hyperplasia, 21-hydroxylase deficiency, and salt-losing congenital adrenal hyperplasia.

All neoplasms, whether functionally active or not, are classified in Chapter 2.However, codes E05.8, E07.0, E16-E31, and E34.- may be used as additional codes to indicate functional activity by neoplasms, ectopic endocrine tissue, or hyper/hypofunction associated with neoplasms and other conditions.Transitory endocrine and metabolic disorders specific to newborns (P70-P74) are excluded from this chapter.

Medical necessity for services related to congenital adrenogenital disorders relies on demonstrating the presence of the condition and its impact on the patient's health.Documentation should clearly link the diagnosis to the specific signs, symptoms, and test results.Medical necessity for treatments like hormone replacement therapy should justify the intervention based on the patient's specific needs and the potential benefits and risks of treatment.

Diagnosis and management of congenital adrenogenital disorders often involves a multidisciplinary team including endocrinologists, pediatricians, and geneticists.Physicians diagnose the condition based on patient history, physical exam, and diagnostic tests such as gene testing, newborn screening, blood and urine hormone levels, and imaging studies (MRI, CT, bone X-rays). Treatment focuses on restoring hormonal balance through hormone replacement therapy.

In simple words: Congenital adrenogenital disorders are inherited conditions affecting the adrenal glands. These glands, located above the kidneys, don't produce the right amount of hormones because of a missing enzyme. This can cause a variety of problems, including unusual early puberty changes, and differences in male and female characteristics.

Congenital adrenogenital disorders associated with enzyme deficiency refers to a set of inherited medical conditions where the adrenal glands produce abnormal amounts of adrenal hormones due to enzyme deficiencies (e.g., 21-hydroxylase, 11 beta-hydroxylase, 17 alpha-hydroxylase).These disorders can lead to various imbalances of corticosteroids, mineralocorticoids, and androgens, resulting in a range of symptoms like virilism, feminization, pseudopuberty, macrogenitosomia praecox, and others. General symptoms can include weakness, blood sugar fluctuations, blood pressure irregularities, headaches, irregular menses, irritability, excessive hair growth, and infertility.

Example 1: A newborn presents with ambiguous genitalia during a routine screening.Laboratory tests reveal elevated 17-hydroxyprogesterone levels, confirming the diagnosis of 21-hydroxylase deficiency, a form of congenital adrenal hyperplasia., A young female child exhibits signs of virilization, including hirsutism and a deepened voice. Further investigation diagnoses congenital adrenal hyperplasia due to an enzyme deficiency., An infant experiences recurrent vomiting, dehydration, and failure to thrive. Diagnostic testing leads to a diagnosis of salt-losing congenital adrenal hyperplasia, requiring immediate hormone replacement therapy.

Documentation should include complete patient history, physical examination findings, results of laboratory and genetic tests (hormone levels, electrolyte panels, gene analysis), imaging reports (if applicable), and details of treatment plans, including medication prescribed and dosage.
