E25.0
Congenital adrenogenital disorders associated with enzyme deficiency
Clinical Classification Guidelines
Inclusion Terms
- Congenital adrenal hyperplasia
- 21-Hydroxylase deficiency
- Salt-losing congenital adrenal hyperplasia
Medical Intelligence & Overview
Congenital adrenogenital disorders are a group of rare conditions present at birth that affect the development of the adrenal glands and influence hormone production. The most common form of these disorders is congenital adrenal hyperplasia (CAH), particularly due to a deficiency in the enzyme 21-hydroxylase. This can lead to various physical and hormonal changes, often affecting sexual development and electrolyte balance. Recognizing and understanding these disorders can help in managing their effects effectively.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting the genes responsible for producing adrenal enzymes Inheritance of defective genes from parents, typically following an autosomal recessive pattern Specific enzyme deficiency, most notably 21-hydroxylase deficiency, leading to impaired synthesis of cortisol and aldosterone
Key Symptoms: Ambiguous genitalia in newborn females Virilization, leading to increased body hair and other masculine features Salt-wasting crises characterized by dehydration, low blood pressure, and electrolyte imbalance Rapidly enlarging adrenal glands Delayed or suppressed puberty Possible hormonal imbalances resulting in irregular menstrual cycles or infertility
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a combination of physical examinations, hormonal blood tests measuring levels of cortisol, and the characteristic increase in androgen hormones. Newborn screening programs also detect elevated levels of 17-hydroxyprogesterone, a marker for 21-hydroxylase deficiency. Imaging studies such as ultrasound may be used to assess adrenal gland size. Genetic testing can confirm the specific mutations responsible for the enzyme deficiency.
Treatment Protocols: Glucocorticoid therapy to suppress excess androgen production and replace cortisol levels Mineralocorticoid (aldosterone) replacement in salt-wasting forms to maintain electrolyte balance Monitoring of hormone levels and growth parameters Surgical interventions may be considered for ambiguous genitalia, depending on individual cases and age
Clinical Advice & FAQs
Billing Guidance
Is E25.0 a billable ICD-10 code?
Yes, E25.0 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report E25.0?
Clinical documentation must specify the nature of Congenital adrenogenital disorders associated with enzyme deficiency and any associated comorbidities for accurate reporting.
