What This Code Means
L89.891 is the ICD-10-CM diagnosis code for pressure ulcer of other site, stage 1. A stage 1 pressure ulcer on a body site other than the common pressure areas, characterized by redness of the skin that does not blanch (turn white) when pressed. L89.891 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).
L89.891 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.
Stage 1 ulcers have intact skin; document whether the area blanches or non-blanches to confirm the stage.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L89.891 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Stage 1 ulcers have intact skin; document whether the area blanches or non-blanches to confirm the stage
