Final answer:
The correct code for this scenario is for the stage 2 pressure ulcer, as coding guidelines require reflecting the highest stage diagnosed during the patient's admission, regardless of the treatment initiated.
Step-by-step explanation:
The correct statement for this case is: Only the stage 2 pressure ulcer on right buttock is coded because it is the more severe of the two. When coding for pressure ulcers, the highest stage diagnosed during the admission should be coded. In this scenario, even though the patient was admitted with a stage 1 pressure ulcer, it progressed to a stage 2 during her hospital stay.
Therefore, the coding would reflect the most severe condition, which is the stage 2 ulcer. The treatment by the wound care staff does not affect the coding; coding reflects the condition of the patient during the stay. Treatment provided in the hospital is essential for the patient's recovery but is separate from the issue of documentation and coding. Medical coding must accurately reflect the severity of the patient's conditions, and in the case of pressure ulcers, it is crucial to code the most severe stage noted in the medical record during the stay.
