What This Code Means
L89.301 is the ICD-10-CM diagnosis code for pressure ulcer of unspecified buttock, stage 1. A stage 1 pressure ulcer on an unspecified buttock, showing redness of the skin that does not blanch when pressed. L89.301 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).
L89.301 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.
When the specific buttock (left or right) is not documented, use the unspecified buttock code; attempt to clarify laterality in documentation.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for L89.301 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •When the specific buttock (left or right) is not documented, use the unspecified buttock code; attempt to clarify laterality in documentation
- •Stage 1 ulcers have intact skin; ensure non-blanching erythema is documented to support this stage assignment
