Additional Info

• Unstageable- the depth is unknown- full thickness tissue loss in which the base of the ulcer is covered in slough and/or eschar
• Suspected deep tissue injury- depth unknown- purple or maroon localized area of discolored intact skin or blood-filled blister due to damage of underlying soft tissue.
• includes necrotic pressure ulcers where the stage is not indicated

This code covers TWO situations:

• When the stage presumably is known by somebody, but was recorded and so the data collector doesn't have the stage available to them
• When it is "unstageable" from a technical standpoint, i.e. can't see the wound bed.

Includes

• pressure ulcers from rectal tubes, ETT/trach, PEG tube, splints combine with Iatrogenic, complication of medical or surgical care NOS

Coding multiple ulcers

• If there are pressure ulcers on DIFFERENT body parts (e.g. left heel, right heel, coccyx) then code them separately

• If there are multiple pressure ulcers close to each other on the same body part (e.g. coccyx area) then only code the one with the highest/worst stage.

Coding Progression of Ulcers

• Progression of Ulcers should be coded following our guidelines for Acquired Diagnosis combine each stage progression with the date and time it was noted in the chart.

Data

Julie will report on the worst stage from Acquired Diagnosis How will that work now with the locations included? How will the report aggregate? And: which report? It should link to the diagnoses using the wiki infrastructure. If you tell me which report(s) I can set that up. Ttenbergen 15:35, 30 June 2025 (CDT)
