What This Code Means
Z59.861 is the ICD-10-CM diagnosis code for financial insecurity, difficulty paying for utilities. A person struggles to pay for essential utilities such as electricity, gas, water, or heating for their home. Z59.861 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to socioeconomic and psychosocial circumstances (z55-z65).
Z59.861 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 which utilities are problematic when documented (heating, cooling, water, electricity).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Z59.861 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
