Final answer:
The coding and sequencing for this case would be L89.43, L89.42, I96.
Step-by-step explanation:
The coding and sequencing for this case would be option D: L89.43, L89.42, I96. The patient has a stage 3 pressure ulcer of the right hip with gangrene (L89.43) and a stage 2 sacral decubitus ulcer (L89.42). These two codes should be listed first. The code I96 should be listed last as it represents sepsis due to gangrene.
