Fall from stairs and steps due to ice and snow, subs encntr

This code signifies an injury sustained from a fall off stairs or steps, specifically caused by the presence of ice or snow, when the patient is presenting for follow-up care after the initial treatment of the injury. It indicates that the fall itself was due to environmental conditions related to winter weather.

Apply this code when a patient returns for subsequent care (e.g., cast check, physical therapy, wound care) for an injury that was initially caused by slipping on ice or snow on stairs or steps. This code is appropriate for any visit after the initial encounter for the acute injury.

• Ensure the documentation clearly states the fall was due to ice or snow on stairs/steps.
• Verify the encounter type is "subsequent" (D) and not initial (A) or sequela (S).
• Always code the specific injury (e.g., fracture, sprain) first, followed by this external cause code.
