Information for Patients


Cocaine

Also called: Blow, C, Coca, Coke, Crack, Flake, Snow

Cocaine is a white powder. It can be snorted up the nose or mixed with water and injected with a needle. Cocaine can also be made into small white rocks, called crack. Crack is smoked in a small glass pipe.

Cocaine speeds up your whole body. You may feel full of energy, happy, and excited. But then your mood can change. You can become angry, nervous, and afraid that someone's out to get you. You might do things that make no sense. After the "high" of the cocaine wears off, you can "crash" and feel tired and sad for days. You also get a strong craving to take the drug again to try to feel better.

No matter how cocaine is taken, it is dangerous. Some of the most common serious problems include heart attack and stroke. You are also at risk for HIV/AIDS and hepatitis, from sharing needles or having unsafe sex. Cocaine is more dangerous when combined with other drugs or alcohol.

It is easy to lose control over cocaine use and become addicted. Then, even if you get treatment, it can be hard to stay off the drug. People who stopped using cocaine can still feel strong cravings for the drug, sometimes even years later.

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.

Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
