What This Code Means
Y92.820 is the ICD-10-CM diagnosis code for desert as the place of occurrence of the external cause. An injury or accident that occurred while the person was in a desert environment. Y92.820 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering supplementary factors related to causes of morbidity classified elsewhere (y90-y99).
Y92.820 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.
This is a place of occurrence code used to supplement the primary injury diagnosis.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for Y92.820 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
