What This Code Means
L89.899 is the ICD-10-CM diagnosis code for pressure ulcer of other site, unspecified stage. A pressure ulcer on a body site other than the common pressure areas where the stage of severity has not been documented or cannot be determined. L89.899 sits in the ICD-10-CM chapter for diseases of the skin and subcutaneous tissue (l00-l99), within the section covering other disorders of the skin and subcutaneous tissue (l80-l99).
L89.899 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.
Query the provider for stage information if available; this code should only be used when stage is truly unspecified.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L89.899 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
