Code Description

ICD-10 D06 is a billable code used to indicate a diagnosis of carcinoma in situ of cervix uteri.

Key Diagnostic Point:

Carcinoma in situ of the cervix uteri refers to a localized form of cervical cancer where abnormal cells are found in the lining of the cervix but have not invaded deeper tissues or spread to other parts of the body. This condition is often detected through routine Pap smears, which identify precancerous changes in cervical cells. The most common type of carcinoma in situ of the cervix is squamous cell carcinoma in situ, although adenocarcinoma in situ can also occur. Patients diagnosed with this condition typically undergo further evaluation, which may include colposcopy and biopsy to confirm the diagnosis and assess the extent of the disease. Treatment options often involve surgical procedures such as conization or hysterectomy, depending on the patient's age, desire for future fertility, and the extent of the disease. Regular surveillance is crucial for monitoring potential progression to invasive cancer, as untreated carcinoma in situ can lead to invasive cervical cancer over time.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between various types of cervical carcinoma in situ.
  • Understanding the implications of staging and grading.
  • Navigating treatment options and their documentation.
  • Interpreting pathology reports accurately.

Audit Risk Factors

  • Inadequate documentation of biopsy results.
  • Failure to document follow-up care and surveillance.
  • Misclassification of the type of carcinoma in situ.
  • Inconsistent coding of treatment procedures.

Coding Guidelines

Inclusion Criteria

Use D06 When
  • According to the ICD
  • CM coding guidelines, D06 should be used when carcinoma in situ is confirmed through biopsy
  • It is essential to document the type of carcinoma and any treatments provided

Exclusion Criteria

Do NOT use D06 When
  • Exclusions include cases where the carcinoma has progressed to invasive cancer

Frequently Asked Questions

What is the difference between carcinoma in situ and invasive cervical cancer?

Carcinoma in situ refers to abnormal cells that have not invaded surrounding tissues, while invasive cervical cancer indicates that cancer cells have spread beyond the cervix.
