Information for Patients


Toxoplasmosis

Toxoplasmosis is a disease caused by the parasite Toxoplasma gondii. More than 60 million people in the U.S. have the parasite. Most of them don't get sick. But the parasite causes serious problems for some people. These include people with weak immune systems and babies whose mothers become infected for the first time during pregnancy. Problems can include damage to the brain, eyes, and other organs.

You can get toxoplasmosis from

  • Waste from an infected cat
  • Eating contaminated meat that is raw or not well cooked
  • Using utensils or cutting boards after they've had contact with contaminated raw meat
  • Drinking infected water
  • Receiving an infected organ transplant or blood transfusion

Most people with toxoplasmosis don't need treatment. There are drugs to treat it for pregnant women and people with weak immune systems.

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.
