Information for Patients


Poisoning

A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include

  • Prescription or over-the-counter medicines taken in doses that are too high
  • Overdoses of illegal drugs
  • Carbon monoxide from gas appliances
  • Household products, such as laundry powder or furniture polish
  • Pesticides
  • Indoor or outdoor plants
  • Metals such as lead and mercury

The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.

Self-Harm

Self-harm refers to a person's harming their own body on purpose. About 1 in 100 people hurts himself or herself in this way. More females hurt themselves than males. A person who self-harms usually does not mean to kill himself or herself. But they are at higher risk of attempting suicide if they do not get help.

Self-harm tends to begin in teen or early adult years. Some people may engage in self-harm a few times and then stop. Others engage in it more often and have trouble stopping.

Examples of self-harm include

  • Cutting yourself (such as using a razor blade, knife, or other sharp object to cut the skin)
  • Punching yourself or punching things (like a wall)
  • Burning yourself with cigarettes, matches, or candles
  • Pulling out your hair
  • Poking objects through body openings
  • Breaking your bones or bruising yourself

Many people cut themselves because it gives them a sense of relief. Some people use cutting as a means to cope with a problem. Some teens say that when they hurt themselves, they are trying to stop feeling lonely, angry, or hopeless.

It is possible to overcome the urge to hurt yourself. There are other ways to find relief and cope with your emotions. Counseling may help.

ICD-10 Footnotes

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.
