Every wound entry should make the skilled need explicit. The medical-necessity formula combines the skilled action, the RN-level reason it required a nurse, and the measurable effect on the wound or the plan.
The formula
skilled action + RN-level clinical reason + measurable effect on the patient’s condition or plan
Worked examples
• Skilled sterile dressing change and serial measurement of a Stage 3 sacral pressure injury were required to determine that the wound decreased from 3.0 × 2.2 cm to 2.4 × 1.8 cm and that the current offloading order remains effective, avoiding escalation of care.
• Skilled assessment of a diabetic foot ulcer was required to identify new periwound erythema and odor, prompting provider notification and a culture order that initiated antibiotics before the infection progressed to limb-threatening.
• Skilled teaching of repositioning and dressing protection to the caregiver, with return demonstration, was required to prevent recurrent breakdown over the sacrum in a bed-bound patient and to keep the healing wound on trajectory.
