Code Description

ICD-10 N87 is a billable code used to indicate a diagnosis of dysplasia of cervix uteri.

Key Diagnostic Point:

Dysplasia of the cervix uteri refers to abnormal changes in the cells on the surface of the cervix, which can be precursors to cervical cancer. This condition is often detected through routine Pap smears, which identify atypical squamous cells. Cervical dysplasia is categorized into three grades: mild (CIN 1), moderate (CIN 2), and severe (CIN 3), with the latter being the most concerning due to its higher risk of progression to invasive cancer. The etiology of cervical dysplasia is primarily linked to persistent infection with high-risk strains of human papillomavirus (HPV). Other risk factors include smoking, immunosuppression, and long-term use of oral contraceptives. Management of cervical dysplasia may involve monitoring, surgical interventions such as loop electrosurgical excision procedure (LEEP), or conization, depending on the severity and patient factors. Accurate coding for dysplasia is crucial for appropriate treatment planning and follow-up care, as well as for tracking population health trends related to cervical cancer prevention.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation between grades of dysplasia (CIN 1, CIN 2, CIN 3)
  • Need for precise documentation of biopsy results
  • Variability in treatment protocols based on dysplasia severity
  • Potential for co-existing conditions (e.g., HPV infection)

Audit Risk Factors

  • Inadequate documentation of biopsy results
  • Failure to specify the grade of dysplasia
  • Misclassification of dysplasia severity
  • Inconsistent follow-up documentation

Frequently Asked Questions

What is the difference between CIN 1, CIN 2, and CIN 3?

CIN 1 indicates mild dysplasia, CIN 2 indicates moderate dysplasia, and CIN 3 indicates severe dysplasia, with increasing risk of progression to cervical cancer.

How often should women be screened for cervical dysplasia?

Women should begin screening at age 21 and continue every three years until age 29. From ages 30 to 65, they may choose to have a Pap smear alone every three years or a Pap smear plus HPV testing every five years.
