Every eye and vision 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 patient or the plan.
The formula
skilled action + RN-level clinical reason + measurable effect on the patient’s condition or plan
Worked examples
• Skilled recognition of sudden painless monocular vision loss was required to activate emergency eye care for a suspected retinal artery occlusion, a time-critical condition in which delay costs the eye.
• Skilled observation and correction of eye-drop technique was required to ensure a glaucoma patient was actually delivering the drop to the eye, preserving intraocular-pressure control and preventing optic-nerve damage.
• Skilled assessment of a gradual functional-vision decline was required to recognize its contribution to falls and medication errors, prompting an eye-care referral and home safety adaptations that reduced the risk (cross-reference Safety).
