Tuberculosis of cervix

BILLABLE STATUSYes

Code Description

ICD-10 A18.16 is a billable code used to indicate a diagnosis of tuberculosis of cervix.

Key Diagnostic Point:

Tuberculosis of the cervix is a rare form of extrapulmonary tuberculosis that primarily affects women, often as a result of hematogenous spread from a primary pulmonary infection. The cervix may become infected through direct extension from adjacent structures or through the lymphatic system. Clinically, patients may present with symptoms such as abnormal vaginal bleeding, pelvic pain, or a palpable mass. Diagnosis is typically confirmed through a combination of clinical evaluation, imaging studies, and laboratory tests, including cervical biopsy, sputum tests, and chest X-rays to rule out pulmonary involvement. Treatment usually involves a prolonged course of antitubercular medications, including isoniazid, rifampicin, ethambutol, and pyrazinamide, with careful monitoring for drug resistance. Public health implications are significant, as tuberculosis is a contagious disease, necessitating contact tracing and isolation procedures for active cases. The management of tuberculosis of the cervix requires a multidisciplinary approach, involving gynecologists, infectious disease specialists, and public health officials to ensure comprehensive care and prevent transmission.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Rarity of the condition, leading to less familiarity among coders.
  • Need for precise documentation of symptoms and diagnostic methods.
  • Potential for misdiagnosis with other gynecological conditions.
  • Variability in treatment protocols based on drug resistance.

Audit Risk Factors

  • Inadequate documentation of diagnostic tests performed.
  • Failure to document the patient's history of tuberculosis exposure.
  • Lack of clarity in distinguishing between active and latent tuberculosis.
  • Insufficient detail regarding treatment adherence and monitoring.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of tuberculosis cases, including those affecting the cervix. This specificity aids in better tracking of disease prevalence and treatment outcomes, enhancing public health responses.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of tuberculosis cases, including those affecting the cervix. This specificity aids in better tracking of disease prevalence and treatment outcomes, enhancing public health responses.

Reimbursement & Billing Impact

Frequently Asked Questions

What are the common symptoms of tuberculosis of the cervix?

Common symptoms include abnormal vaginal bleeding, pelvic pain, and discharge. Some patients may also experience systemic symptoms such as fever and weight loss.

How is tuberculosis of the cervix diagnosed?

Diagnosis typically involves a combination of clinical evaluation, imaging studies, cervical biopsy, and laboratory tests, including sputum tests to assess for pulmonary involvement.

What is the treatment for tuberculosis of the cervix?

Treatment usually consists of a multi-drug regimen including isoniazid, rifampicin, ethambutol, and pyrazinamide, administered over a period of 6 to 12 months, depending on the patient's response and drug resistance.

What public health measures are necessary for tuberculosis of the cervix?

Public health measures include contact tracing, isolation of active cases, and education on tuberculosis transmission and prevention.
