Code Description

ICD-10 N90.5 is a billable code used to indicate a diagnosis of atrophy of vulva.

Key Diagnostic Point:

Atrophy of the vulva refers to the thinning and shrinking of the vulvar tissues, which can occur due to various factors, including hormonal changes, particularly during menopause. This condition is characterized by a decrease in the elasticity and moisture of the vulvar skin, leading to symptoms such as dryness, irritation, and discomfort. Atrophy can also result in a reduction of the vulvar fat pad, which may contribute to pain during intercourse (dyspareunia) and increased susceptibility to trauma and infections. The condition is often associated with other noninflammatory disorders of the female genital tract, such as vaginal atrophy, which is a similar process affecting the vaginal walls. Clinicians may encounter atrophy of the vulva in patients with a history of estrogen deficiency, such as postmenopausal women or those undergoing certain cancer treatments. Diagnosis typically involves a thorough clinical examination and may require a review of the patient's hormonal status. Treatment options may include topical estrogen therapy, moisturizers, and lifestyle modifications to alleviate symptoms and improve quality of life.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of hormonal influences on vulvar health.
  • Differentiation from other vulvar conditions (e.g., lichen sclerosus).
  • Documentation of symptoms and patient history is critical.
  • Potential overlap with other ICD-10 codes related to vulvar disorders.

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings.
  • Misdiagnosis due to overlapping symptoms with other vulvar conditions.
  • Failure to document treatment plans or follow-up care.
  • Incorrect linkage of diagnosis to procedures performed.
