Code Description

ICD-10 N86 is a billable code used to indicate a diagnosis of erosion and ectropion of cervix uteri.

Key Diagnostic Point:

Erosion and ectropion of the cervix uteri are conditions characterized by the abnormal exposure of the cervical epithelium. Erosion refers to the loss of the epithelial layer, often resulting from chronic inflammation or hormonal changes, while ectropion involves the eversion of the cervical tissue, exposing the inner lining to the vaginal canal. These conditions can lead to symptoms such as abnormal vaginal discharge, bleeding, and discomfort during intercourse. They are often associated with hormonal fluctuations, particularly during pregnancy or with the use of oral contraceptives. While these conditions are generally benign, they can be indicative of underlying cervical dysplasia or other cervical pathologies. Diagnosis typically involves a pelvic examination and may be confirmed through colposcopy and biopsy if necessary. Treatment options may include observation, cauterization, or surgical intervention depending on the severity and associated symptoms. Understanding these conditions is crucial for proper management and coding, as they can impact a patient's reproductive health and require careful monitoring.

Complexity Factors

  • Differentiating between erosion and ectropion
  • Potential overlap with cervical dysplasia codes
  • Need for detailed documentation of symptoms
  • Variability in treatment approaches

Audit Risk Factors

  • Inadequate documentation of symptoms
  • Failure to specify the type of erosion or ectropion
  • Misclassification with inflammatory conditions
  • Lack of follow-up documentation

Specialty Focus

Medical Specialties

Obstetrics and Gynecology

Documentation Requirements

Detailed patient history, examination findings, and treatment plans must be documented.

Common Clinical Scenarios

Routine gynecological exams revealing cervical abnormalities, follow-up visits for abnormal Pap smears.

Billing Considerations

Coders should ensure that any associated conditions, such as dysplasia, are accurately captured.

Family Medicine

Documentation Requirements

Comprehensive documentation of patient symptoms and any referrals made for further evaluation.

Common Clinical Scenarios

Patients presenting with abnormal vaginal bleeding or discharge.

Billing Considerations

Family practitioners should be aware of the need for referrals to specialists for definitive diagnosis and treatment.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of cervical conditions, improving the accuracy of diagnoses and treatment tracking. N86 provides a clear distinction between erosion and ectropion, which aids in clinical management.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of cervical conditions, improving the accuracy of diagnoses and treatment tracking. N86 provides a clear distinction between erosion and ectropion, which aids in clinical management.
