Clostridium Difficile Infections

Also called: C. diff. infections, Clostridium enterocolitis, pseudomembranous colitis

  • Watery diarrhea (at least three bowel movements per day for two or more days)
  • Fever
  • Loss of appetite
  • Nausea
  • Abdominal pain or tenderness

C. difficile is more common in people who need to take antibiotics for a long period of time.The elderly also have a higher risk of getting it. The infection can spread in hospitals and nursing homes.

Tests of your stool can diagnose C. difficile. Sometimes you might also need imaging tests, to check for complications. Certain antibiotics can treat it. Rarely, there are severe cases that need surgery.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
