Information for Patients
Many people who chew tobacco or dip snuff think it's safer than smoking. But you don't have to smoke tobacco for it to be dangerous. Chewing or dipping carries risks like
- Cancer of the mouth
- Decay of exposed tooth roots
- Pulling away of the gums from the teeth
- White patches or red sores in the mouth that can turn to cancer
Recent research shows the dangers of smokeless tobacco may go beyond the mouth. It might also play a role in other cancers, heart disease and stroke.
Smokeless tobacco contains more nicotine than cigarettes. Nicotine is a highly addictive drug that makes it hard to stop using tobacco once you start. Having a quit date and a quitting plan can help you stop successfully.

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.
