Information for Patients
Coronaviruses are common viruses that most people get some time in their life. They are common throughout the world, and they can infect people and animals. Several different coronaviruses can infect people and make them sick. They usually cause mild to moderate upper-respiratory illness. But, some coronaviruses can cause severe illness.
Coronaviruses probably spread through the air by coughing or sneezing, or by close personal contact. If you get infected, symptoms may include
- Runny nose
- Sore throat
You may be able to reduce your risk of infection by washing your hands often with soap and water, not touching your eyes, nose, or mouth, and avoiding close contact with people who are sick. There is no vaccine to prevent coronavirus infection. There are no specific treatments. You can relieve symptoms with pain and fever medicines and rest.

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.
