Coding W57.XXX lacks specificity, impacting reimbursement and data analysis. CDI should query for details like insect type.
Insect bite with allergic reaction may be miscoded as W57.XXX instead of appropriate allergy codes, affecting severity capture.
Infected insect bite might be initially coded as W57.XXX, delaying appropriate treatment and impacting quality metrics.
