Tuberculosis of spine

BILLABLE STATUSYes

Code Description

ICD-10 A18.01 is a billable code used to indicate a diagnosis of tuberculosis of spine.

Key Diagnostic Point:

Tuberculosis of the spine, also known as Pott's disease, is a form of extrapulmonary tuberculosis that primarily affects the vertebrae. It occurs when Mycobacterium tuberculosis spreads from the lungs or other infected sites to the spine, leading to vertebral osteomyelitis. The condition is characterized by back pain, fever, weight loss, and neurological deficits if the spinal cord is compressed. Diagnosis typically involves imaging studies such as X-rays, MRI, or CT scans, alongside microbiological tests like sputum cultures or PCR for Mycobacterium tuberculosis. Treatment usually includes a prolonged course of antitubercular medications, often for 6 to 12 months, and may require surgical intervention in cases of severe deformity or neurological compromise. Monitoring for drug resistance is crucial, as multidrug-resistant tuberculosis (MDR-TB) can complicate treatment. Public health implications are significant, necessitating contact tracing and isolation procedures to prevent transmission, especially in high-risk populations.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between pulmonary and extrapulmonary tuberculosis
  • Need for comprehensive documentation of symptoms and diagnostic tests
  • Potential for drug resistance complicating treatment
  • Variability in presentation and severity of the disease

Audit Risk Factors

  • Inadequate documentation of diagnostic tests performed
  • Failure to document the extent of spinal involvement
  • Lack of follow-up notes on treatment response
  • Misclassification of the type of tuberculosis

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of tuberculosis cases, including spinal involvement, which aids in better tracking and management of the disease.

ICD-9 vs ICD-10

Frequently Asked Questions

What are the common symptoms of tuberculosis of the spine?

Common symptoms include localized back pain, fever, night sweats, weight loss, and neurological deficits if the spinal cord is affected.

How is tuberculosis of the spine diagnosed?

Diagnosis is typically made through imaging studies such as X-rays or MRI, along with microbiological tests like sputum cultures or PCR.

What is the treatment for tuberculosis of the spine?

Treatment usually involves a combination of antitubercular medications for 6 to 12 months, and surgical intervention may be necessary in severe cases.

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

Public health measures include contact tracing, isolation of infectious patients, and monitoring for drug resistance.
