L89.529 ICD-10-CM Code: Pressure ulcer of left ankle, unspecified stage

L89.529 is the ICD-10-CM diagnosis code for pressure ulcer of left ankle, unspecified stage. A pressure ulcer on the left ankle where the specific stage of severity cannot be determined or is not documented. L89.529 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).

L89.529 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.

Use only when stage cannot be clinically assessed or is not documented; query provider for stage information when possible.
