Precocious puberty
ICD-10 E30.1 is a billable code used to indicate a diagnosis of precocious puberty.
Precocious puberty is defined as the onset of secondary sexual characteristics before age 9 in boys and before age 8 in girls. This condition can be classified into central precocious puberty (gonadotropin-dependent) and peripheral precocious puberty (gonadotropin-independent). Central precocious puberty is often due to early activation of the hypothalamic-pituitary-gonadal (HPG) axis, which can be idiopathic or secondary to conditions such as tumors or congenital adrenal hyperplasia. Peripheral precocious puberty may arise from excess sex steroid production from adrenal tumors, ovarian cysts, or exogenous hormone exposure. Clinically, children may present with breast development, pubic hair growth, and accelerated growth velocity. Diagnosis typically involves a combination of clinical evaluation, hormone level testing, and imaging studies to identify underlying causes. Early diagnosis and management are crucial to prevent psychosocial issues and complications related to premature skeletal maturation.
Detailed growth charts, age of onset, and physical examination findings.
Evaluation of a child presenting with early breast development or testicular enlargement.
Consider psychosocial impacts on the child and family, and document any referrals to endocrinology.
Comprehensive hormonal assessments and imaging studies to identify any underlying pathology.
Management of a child with confirmed precocious puberty and suspected adrenal or gonadal tumors.
Document the rationale for any hormonal therapies or surgical interventions.
Used to confirm diagnosis in girls presenting with early breast development.
Document the clinical indication for the test and results.
Endocrinologists may require additional tests to assess adrenal function.
Precocious puberty is diagnosed when secondary sexual characteristics appear before age 9 in boys and before age 8 in girls.
