Clinical Information

A severe condition resulting from bacteria invading healthy muscle from adjacent traumatized muscle or soft tissue. The infection originates in a wound contaminated with bacteria of the genus clostridium. C. Perfringens accounts for the majority of cases (over eighty percent), while c. Noyvi, c. Septicum, and c. Histolyticum cause most of the other cases.

ICD-10-CM A48.0 is grouped within Diagnostic Related Group(s) (MS-DRG v36.0):

793 Full term neonate with major problems
867 Other infectious and parasitic diseases diagnoses with mcc
868 Other infectious and parasitic diseases diagnoses with cc
