What is itching?
Itching is an irritating sensation that makes you want to scratch your skin. Sometimes it can feel like pain, but it is different. Often, you feel itchy in one area in your body, but sometimes you may feel itching all over. Along with the itching, you may also have a rash or hives.
What causes itching?
Itching is a symptom of many health conditions. Some common causes are
- Allergic reactions to food, insect bites, pollen, and medicines
- Skin conditions such as eczema, psoriasis, and dry skin
- Irritating chemicals, cosmetics, and other substances
- Parasites such as pinworms, scabies, head and body lice
- Liver, kidney, or thyroid diseases
- Certain cancers or cancer treatments
- Diseases that can affect the nervous system, such as diabetes and shingles
What are the treatments for itching?
Most itching is not serious. To feel better, you could try
- Applying cold compresses
- Using moisturizing lotions
- Taking lukewarm or oatmeal baths
- Using over-the-counter hydrocortisone cream or antihistamines
- Avoiding scratching, wearing irritating fabrics, and exposure to high heat and humidity
Contact your health care provider if your itching is severe, does not go away after a few weeks, or does not have an apparent cause. You may need other treatments, such as medicines or light therapy. If you have an underlying disease that is causing the itching, treating that disease may help.

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.
