Try your hand at coding these two RAI User's Manual examples below: Scenario No. 1: "A resident has a Stage 2 pressure ulcer on the right heel and no other pressure ulcers." Scenario No. 2: "A resident has a pressure ulcer on the left trochanter that has 25 percent black necrotic tissue present, 75 percent granulation tissue present, and some epithelialization at the edges of the wound." Coding options and instructions: "Code 1, epithelial tissue: if the wound is superficial and is re-epithelializing. Code 2, granulation tissue: if the wound is clean (e.g., free of slough and necrotic tissue) and contains granulation tissue. Code 3, slough: if there is any amount of slough present and necrotic tissue is absent. Code 4, necrotic tissue (eschar): if there is any necrotic tissue (eschar) present." Source: RAI User's Manual Coding Quizzer Answer Scenario No. 1: You would code "1" (epithelial tissue) at M0700. "Rationale: Coding for M0700 is Code 1, (Epithelial tissue) because epithelial tissue is consistent with identification of this pressure ulcer as a Stage 2 pressure ulcer," states the RAI User's Manual. Scenario No. 2: You'd code a "4" (necrotic tissue) at M0700. "Rationale: Coding is for the most severe tissue type present, which is not always the majority of type of tissue. Therefore, Coding for M0700 is Code 4, (Necrotic tissue)," the manual directs.
