What ICD-10 Codes are Used for Amenorrhea

Amenorrhea refers to the absence of menstruation in women who are of reproductive age. This condition can be caused by various underlying factors, and for accurate diagnosis and billing purposes, the ICD-10 (International Classification of Diseases, 10th Revision) coding system provides specific codes to represent these causes. 

Below are the clinical descriptions of some commonly used Amenorrhea ICD-10 codes:

  • N91.0 - Primary Amenorrhea: This code is used when a female has not experienced menstruation by the age of 16 despite normal growth and secondary sexual characteristics.
  • N91.1 - Secondary Amenorrhea: Secondary amenorrhea is the absence of menstruation for three or more consecutive cycles in women who have previously had a regular menstrual cycle.
  • E28.8 - Other Ovarian Dysfunction: This code may be used for amenorrhea related to ovarian dysfunction not categorized elsewhere, such as polycystic ovary syndrome (PCOS) or premature ovarian failure.
  • E28.2 - Polycystic Ovarian Syndrome (PCOS): PCOS is a common hormonal disorder in women, often causing amenorrhea or irregular periods, along with other symptoms like cystic ovaries and hyperandrogenism.
  • E28.3 - Primary Ovarian Failure: Primary ovarian failure, also known as premature ovarian insufficiency, is a condition where the ovaries stop functioning before the age of 40, leading to amenorrhea and infertility.
  • N91.2 - Oligomenorrhea: Oligomenorrhea is characterized by infrequent or irregular menstruation, which may lead to periods of amenorrhea.
  • N91.4 - Hypothalamic Dysfunction: This code is used for amenorrhea associated with disorders affecting the hypothalamus, which is crucial in regulating the menstrual cycle.
  • E28.0 - Estrogen Excess: Amenorrhea may result from excessive estrogen levels, which can be due to conditions like estrogen-producing tumors or hormone therapy side effects.
  • N92.0 - Excessive and Frequent Menstruation with Regular Cycle: This code is used when there's concern about amenorrhea being caused by excessive or frequent menstruation within a regular cycle, suggesting a possible underlying issue.
  • N91.3 - Secondary Amenorrhea Due to Pregnancy: Secondary amenorrhea can occur when pregnancy is the cause. This code indicates that the absence of menstruation is due to pregnancy.

Which Amenorrhea ICD Codes are Billable

ICD-10 codes for amenorrhea may be billable, depending on the healthcare provider's services, the patient's insurance, and the medical necessity of the procedures or treatments provided. Here are some commonly used codes:

  • N91.0 - Primary Amenorrhea: Yes.
  • N91.1 - Secondary Amenorrhea: Yes.
  • E28.8 - Other Ovarian Dysfunction: Yes.
  • E28.2 - Polycystic Ovarian Syndrome (PCOS): Yes.
  • E28.3 - Primary Ovarian Failure: Yes.
  • N91.2 - Oligomenorrhea: Yes.
  • N91.4 - Hypothalamic Dysfunction: Yes.
  • E28.0 - Estrogen Excess: Yes.
  • N92.0 - Excessive and Frequent Menstruation with Regular Cycle: Not used for billing as it denotes pregnancy rather than a medical condition.
  • N91.3 - Secondary Amenorrhea Due to Pregnancy: Not used for billing as it denotes pregnancy rather than a medical condition.

Medical coding and billing practices vary based on the healthcare provider, insurance policies, and services. Accurate ICD-10 codes should be used to ensure proper reimbursement and documentation. Insurance companies have specific guidelines for billing, so it's crucial to follow their instructions for successful reimbursement.

Clinical Information

  • Amenorrhea is the absence of menstrual periods in women of reproductive age, and it can result from various underlying causes and conditions.
  • It is categorized into two main types: primary amenorrhea, where a female has not started menstruating by the age of 16, and secondary amenorrhea, which is the cessation of menstruation for three or more consecutive cycles after regular periods.
  • Common causes of primary amenorrhea include genetic factors, anatomical abnormalities of the reproductive system, and hormonal imbalances.
  • Secondary amenorrhea is often associated with factors such as pregnancy, stress, excessive exercise, extreme weight loss or gain, certain medications, and medical conditions like polycystic ovarian syndrome (PCOS), thyroid disorders, or hypothalamic dysfunction.
  • Accurate diagnosis and treatment of amenorrhea involve a thorough medical history, physical examination, hormonal tests, imaging studies, and sometimes genetic testing.
  • Treatment strategies vary depending on the underlying cause and may include lifestyle changes, hormone therapy, surgical interventions, or addressing specific medical conditions contributing to amenorrhea.
  • Amenorrhea can have various impacts on a woman's overall health, including fertility issues, bone health concerns, and potential emotional and psychological effects.
  • Proper evaluation and management of amenorrhea are crucial to address the underlying causes and improve the patient's well-being and reproductive health.
