To accurately code a pressure ulcer in ICD-10-CM, the code must reflect the ulcer's location and stage. The codes for pressure ulcers specify both the anatomical site and the stage (extent of tissue damage).
L89.613 represents a pressure ulcer on the right heel at stage 3. The stage is critical as it indicates the severity of the ulcer, with stage 3 involving full-thickness skin loss and possibly visible subcutaneous tissue.
A: L89.609 refers to a pressure ulcer on the heel but without specific staging.
C: L89.619 is for a pressure ulcer on the right heel at stage 4, which indicates a more severe level of tissue damage than stage 3.
D: L89.603 represents a stage 3 pressure ulcer but on the left heel, not the right.
Therefore, the correct answer is B. L89.613 for a stage 3 pressure ulcer on the right heel.
