Is K82.A2 an HCC code?
No. K82.A2 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
K82.A2 is the ICD-10-CM diagnosis code for perforation of gallbladder in cholecystitis. A rupture or hole in the gallbladder wall that develops as a result of inflammation, which is a medical emergency that can lead to peritonitis. K82.A2 sits in the ICD-10-CM chapter for diseases of the digestive system (k00-k95), within the section covering disorders of gallbladder, biliary tract and pancreas (k80-k87).
K82.A2 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.
Requires documentation of both perforation AND cholecystitis; do not assign if only one condition is documented.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for K82.A2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Requires documentation of both perforation AND cholecystitis; do not assign if only one condition is documented
- •This is typically an acute/emergent condition; verify appropriate severity coding and consider sepsis codes if present
