We had a resident admitted who stayed a few days, then back to hospital, readmitted to us for 36 hrs, then back to hospital, now back again. Already did two PPS assessments that I combined with the discharges. She had documented everywhere-referral forms from hospital and last SNF, MD history and physical on both admits to us, admission nursing assessments, etc multiple stage 2 and 3 pressure ulcers. All were coded on section M on those two assessments already done and transmitted. Now on this last admission, the DON states the areas are not pressure ulcers, but should be coded as other lesions, as they are the result of shingles she had 3 years ago. She states she has now documented this in a nurses note and has discussed it with the RNP in the building as well. Does that make sense to anyone out there? I am not sure what to do about this-do I modify the two assessments I already sent in? Do I code these areas as other lesions? How can we be sure they are not pressure related? Anyone have any advice on this one please.........
