Clinical Information

• Menarche

  the first menstrual cycle marked by the initiation of menstruation.

• Adrenocortical Hyperfunction

  excess production of adrenal cortex hormones such as aldosterone; hydrocortisone; dehydroepiandrosterone; and/or androstenedione. hyperadrenal syndromes include cushing syndrome; hyperaldosteronism; and virilism.

• Age at Menarche|MENARAGE|Menarche Age|Menarche Age

  age of first menstruation. a risk factor for breast cancer

• Isolated Premature Menarche|Premature Menarche

  occurrence of the first menstrual period in a girl before the lower limit of the normal age range for the reference population, without other signs of puberty.

• Menarche

  onset of menses.

• Premature Menarche

  occurrence of the first menstrual period in a female before the usual or expected age.

• Primary Amenorrhea|Delayed Menarche|Delayed Menarche

  abnormally late or absent menarche in a female with normal secondary sexual characteristics.

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

• Pediatric diagnoses - The Medicare Code Editor detects inconsistencies in pediatric cases by checking a patient's age and any diagnosis on the patient's record. The pediatric code edits apply to patients age range is 0–17 years inclusive (e.g., Reye's syndrome, routine child health exam).

E30.1 is grouped with Diagnostic Related Groups - MS-DRG Mapping

Diagnostic Related Groups (DRGs) are a classification system used to group together diagnosis codes for the purpose of reimbursement and healthcare management. DRGs are used to standardize the way hospitals and other providers are paid for inpatient services. In this system patients are grouped together based on their principal diagnosis in areas referred to as Major Diagnostic Categories (MDC). Once a patient is assigned a particular diagnostic category, providers receive a predetermined payment rate for the services rendered. This reimbursement rate is often fixed and is meant to cover the cost of care for that patient. Reimbursement is also affected by the relative weight of a diagnostic related group based on the severity of a patient's illness and the associated cost of care during hospitalization.

Diagnostic related groups encourage healthcare providers to focus on quality and efficiency in patient care while managing costs effectively. The diagnosis code is present in the following groups for version MS-DRG V41.0 applicable from 10/01/2023 through 09/30/2024.

MS-DRG	MS-DRG Title	MCD	Relative Weight
643	ENDOCRINE DISORDERS WITH MCC	10	1.6451
644	ENDOCRINE DISORDERS WITH CC	10	1.0617
645	ENDOCRINE DISORDERS WITHOUT CC/MCC	10	0.7609

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

Convert E30.1 to ICD-9-CM

• ICD-9-CM Code: 259.1 - Sexual precocity NEC
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Puberty

Puberty is the time in life when a boy or girl becomes sexually mature. It is a process that usually happens between ages 10 and 14 for girls and ages 12 and 16 for boys. It causes physical changes, and affects boys and girls differently.

In girls:

• The first sign of puberty is usually breast development.
• Then hair grows in the pubic area and armpits.
• Menstruation (or a period) usually happens last.

In boys:

• Puberty usually begins with the testicles and penis getting bigger.
• Then hair grows in the pubic area and armpits.
• Muscles grow, the voice deepens, and facial hair develops as puberty continues.

Both boys and girls may get acne. They also usually have a growth spurt (a rapid increase in height) that lasts for about 2 or 3 years. This brings them closer to their adult height, which they reach after puberty.

Central precocious puberty

Central precocious puberty is a condition that causes early sexual development in girls and boys. While puberty normally starts between ages 8 and 13 in girls and between ages 9 and 14 in boys, girls with central precocious puberty begin exhibiting signs before age 8, and boys with this disorder begin before age 9. Signs of puberty include development of pubic and underarm hair, a rapid increase in height (commonly referred to as a "growth spurt"), acne, and underarm odor. Girls also develop breasts and begin their menstrual periods. Boys have growth of the penis and testes and deepening of the voice. Because of the early growth spurt, children with central precocious puberty may be taller than their peers; however, they may stop growing abnormally early. Without proper treatment, some affected individuals are shorter in adulthood compared with other members of their family. Developing ahead of their peers can be emotionally difficult for affected individuals and may lead to psychological and behavioral problems.
