Is G06.0 an HCC code?
No. G06.0 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
G06.0 is the ICD-10-CM diagnosis code for intracranial abscess and granuloma. A collection of pus or inflammatory tissue inside the skull, either as an abscess or granuloma. G06.0 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).
G06.0 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Specify the location (epidural, subdural, or intracerebral) if documented, as this may allow for a more specific code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G06.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Specify the location (epidural, subdural, or intracerebral) if documented, as this may allow for a more specific code
- •Document whether this is an abscess or granuloma, as treatment approaches differ significantly
