Thickened Endometrium ICD-10-CM Codes

What ICD-10 Codes Are Used for Thickened Endometrium?

Thickened endometrium, also known as endometrial hyperplasia, typically appears in postmenopausal women, marked by the thickening of the endometrium lining. The following are the primary Thickened Endometrium ICD codes:

• N85.00 - Unspecified endometrial hyperplasia: This is a general code used when specific details are not provided.
• N85.02 - Simple endometrial hyperplasia without atypia: For simple hyperplasia cases without cellular abnormalities.
• N85.03 - Complex endometrial hyperplasia without atypia: Used for complex hyperplasia with no cellular atypicality.
• N85.04 - Simple endometrial hyperplasia with atypia: This code indicates simple hyperplasia with cellular atypicality.
• N85.05 - Complex endometrial hyperplasia with atypia: Describes complex endometrial hyperplasia with atypical cellular structure.
• N85.8 - Other specified noninflammatory disorders of uterus: Used when there is another specific noninflammatory condition of the uterus in addition to endometrial hyperplasia.
• N85.9 - Noninflammatory disorder of uterus, unspecified: Used when the noninflammatory disorder of the uterus is unspecified and confirmed.

Which Thickened Endometrium ICD Codes Are Billable?

The identification of billable codes is critical for accurate insurance reimbursement. Here are the billable codes:

• N85.00 - Yes, it covers the general condition of endometrial hyperplasia.
• N85.02 - Yes, this code is billable and specifies simple endometrial hyperplasia without atypia.
• N85.03 - Yes, complex hyperplasia without atypia is covered under this billable code.
• N85.04 - Yes, simple hyperplasia with atypia is billable.
• N85.05 - Yes, this billable code is used for complex hyperplasia with atypia.
• N85.8 - Yes, other specific noninflammatory disorders of the uterus are billable.
• N85.9 - Yes, this code is billable when the noninflammatory disorder is unspecified.

Clinical Information

A thickened endometrium, or endometrial hyperplasia, is often found in postmenopausal women and involves the excessive proliferation of the endometrium cells or the lining of the uterus.

• The endometrium is responsive to estrogen; prolonged exposure can lead to its thickening.
• This condition can be simple or complex and can present with or without atypia.
• It may lead to heavy, irregular, or prolonged menstrual bleeding.
• In severe instances, it can lead to endometrial cancer, especially when atypia is present.
• Diagnosis often involves a pelvic ultrasound and a biopsy of the endometrium.
• Treatment depends on the severity and type of hyperplasia, the patient's age, and her desire for future fertility. It may include progestin therapy, hysterectomy, or close monitoring.

Synonyms Include:

• Endometrial hyperplasia
• Hyperplasia of endometrium
• Thick uterus lining
• Uterus lining overgrowth
