Code Description

ICD-10 G02 is a billable code used to indicate a diagnosis of meningitis in other infectious and parasitic diseases classified elsewhere.

Key Diagnostic Point:

G02 refers to meningitis that occurs as a complication of other infectious and parasitic diseases that are classified in different categories within the ICD-10 system. This condition is characterized by the inflammation of the protective membranes covering the brain and spinal cord, known as the meninges. Meningitis can be caused by various infectious agents, including bacteria, viruses, fungi, and parasites. The clinical presentation may include fever, headache, neck stiffness, altered mental status, and photophobia. Diagnosis typically involves a combination of clinical evaluation, lumbar puncture for cerebrospinal fluid analysis, and imaging studies. The management of G02 involves treating the underlying infectious disease, which may include antibiotics, antivirals, or antifungals, depending on the causative agent. It is crucial for healthcare providers to accurately identify the underlying condition to ensure appropriate treatment and coding.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of underlying infectious diseases
  • Differentiation from other types of meningitis
  • Potential for multiple coding options based on the primary disease
  • Need for precise documentation of the infectious agent

Audit Risk Factors

  • Inadequate documentation of the underlying infectious disease
  • Failure to specify the type of meningitis
  • Incorrect coding of the primary condition leading to meningitis
  • Lack of clarity in clinical notes regarding symptoms and treatment

Specialty Focus

Medical Specialties

Infectious Disease

Documentation Requirements

Detailed history of the infectious disease, laboratory results, and treatment plans.

Common Clinical Scenarios

Patients presenting with fever and neurological symptoms following a known infectious disease.

Billing Considerations

Ensure that the primary infectious disease is well-documented to support the use of G02.

Neurology

Documentation Requirements

Neurological examination findings, imaging results, and lumbar puncture results.

Common Clinical Scenarios

Patients with altered mental status and signs of meningitis after a recent infection.

Billing Considerations

Document neurological deficits and any changes in mental status to support the diagnosis.

Coding Guidelines

Inclusion Criteria

Use G02 When
  • According to ICD
  • 10 coding guidelines, G02 should be used when meningitis is a complication of an infectious disease classified elsewhere
  • Coders must ensure that the primary condition is coded first, followed by G02

Exclusion Criteria

Do NOT use G02 When
  • It is essential to follow the inclusion and exclusion criteria outlined in the coding manual

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of meningitis cases, including those related to other infectious diseases. This specificity aids in better tracking of epidemiological trends and improves the accuracy of healthcare data.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of meningitis cases, including those related to other infectious diseases. This specificity aids in better tracking of epidemiological trends and improves the accuracy of healthcare data.
