What This Code Means

G02 is the ICD-10-CM diagnosis code for meningitis in other infectious and parasitic diseases classified elsewhere. Inflammation of the membranes surrounding the brain and spinal cord that occurs as a complication of an infectious or parasitic disease classified elsewhere in the medical record. G02 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering inflammatory diseases of the central nervous system (g00-g09).

G02 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28, V24, ESRD, or RxHCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

This code requires a secondary diagnosis code for the underlying infectious or parasitic disease.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for G02 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
