Other salmonella infections
In Intestinal infectious diseases (A00-A09), chapter 1: Certain Infectious and Parasitic Diseases
11 billable codes under A02: 3 are an MCC, 7 are a CC; 3 map to HCC 92 (Bone/Joint/Muscle/Severe Soft Tissue Infections/Necrosis), HCC 2 (Septicemia, Sepsis, Systemic Inflammatory Response Syndrome/Shock).A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

About the condition

Salmonella Infections
Salmonella is the name of a group of bacteria. In the United States, it is a common cause of foodborne illness. Salmonella occurs in raw poultry, eggs, beef, and sometimes on unwashed fruit and vegetables. You also can get infected after handling pets, especially reptiles like snakes, turtles, and lizards.
