What This Code Means
L89.526 is the ICD-10-CM diagnosis code for pressure-induced deep tissue damage of left ankle. Deep tissue damage from pressure on the left ankle that appears as a purple or maroon discolored area, indicating tissue death beneath intact skin. L89.526 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).
L89.526 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 code represents suspected deep tissue injury (SDTI) with intact skin; do not use if skin is already broken.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L89.526 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code represents suspected deep tissue injury (SDTI) with intact skin; do not use if skin is already broken
- •Document the color changes and location precisely; this stage may progress to higher stages if skin integrity is lost
