Precocious puberty

This code represents precocious puberty that is not specifically classified as central or due to other defined endocrine disorders. It signifies the premature onset of pubertal development, including the appearance of secondary sexual characteristics, before the typical age range (generally before age 8 in girls and age 9 in boys), when the underlying cause is not identified as central or adrenal in origin.

Use this code when documentation indicates precocious puberty without a clear etiology, or when the cause is determined to be peripheral but not specifically linked to adrenal hyperplasia or other specified pseudopuberty syndromes. This code is appropriate when diagnostic workup has ruled out central precocious puberty and other specific causes listed in the Excludes1 note.

• Carefully review documentation to differentiate between central precocious puberty (E22.8) and other forms, as these are mutually exclusive.
• Ensure that specific causes of pseudopuberty, such as congenital adrenal hyperplasia (E25.0) or other adrenal disorders, have been ruled out before assigning this code.
• Always check for laterality or specific syndrome documentation that would lead to a more precise code assignment.
