A patient is admitted after a fall at home that caused a hip fracture. How should external cause codes be used for the inpatient stay?
Select an answer to reveal the explanation.
Short Explanation
External cause codes tell the “how it happened” story, but they are never the headliner on an inpatient claim. The injury or illness stays principal; the fall/crash/etc. codes tag along in supporting roles.
Full Explanation
External cause of morbidity codes describe the mechanism, place, and activity related to an injury or health condition. Official guidance treats them as supplemental: they may be reported in addition to a code for the condition itself but are not used as the principal diagnosis for inpatient reporting. The hip fracture (or other nature-of-injury/condition code) remains the diagnosis sequenced according to principal diagnosis guidelines.
