Diagnosis Code W57.XXXD
Information for Medical Professionals
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.
The code W57.XXXD is exempt from POA reporting.

Insect Bites and Stings
Also called: Bug bites
Most insect bites are harmless, though they sometimes cause discomfort. Bee, wasp, and hornet stings and fire ant bites usually hurt. Mosquito and flea bites usually itch. Insects can also spread diseases. In the United States, some mosquitoes spread West Nile virus. Travelers outside the United States may be at risk for malaria and other infections.
To prevent insect bites and their complications
- Don't bother insects
- Use insect repellant
- Wear protective clothing
- Be careful when you eat outside because food attracts insects
- If you know you have severe allergic reactions to insect bites and stings (such as anaphylaxis), carry an emergency epinephrine kit
- Bee poison
- Fire ants
- Insect bites and stings
- Wasp sting
Though many people are afraid of spiders, they rarely bite people unless threatened. Most spider bites are harmless. Occasionally, spider bites can cause allergic reactions. And bites by the venomous black widow and brown recluse spiders can be very dangerous to people.
If you are bitten by a spider, you may see a reaction similar to that of a bee sting, including redness, pain and swelling at the site. To treat a spider bite:
- Wash the area well with soap and water
- Apply an ice pack or a wet compress to the area
- Take over-the-counter pain medicine, if needed
- Consider using antihistamines for severe swelling
- Seek medical treatment for small children and adults with severe symptoms
- Black widow spider
- Brown recluse spider
- Funnel-web spider bite
- Tarantula spider
If you spend time outdoors or have pets that go outdoors, you need to beware of ticks. Ticks are small bloodsucking parasites. Many species transmit diseases to animals and people. Some of the diseases you can get from a tick bite are Lyme disease, ehrlichiosis, Rocky Mountain spotted fever and tularemia.
Some ticks are so small that they can be difficult to see. Ticks may get on you if you walk through areas where they live, such as tall grass, leaf litter or shrubs.
Tick-borne diseases occur worldwide, including in your own backyard. To help protect yourself and your family, you should
- Use a chemical repellent with DEET, permethrin or picaridin
- Wear light-colored protective clothing
- Tuck pant legs into socks
- Avoid tick-infested areas
- Check yourself, your children and your pets daily for ticks and carefully remove any ticks you find
- Colorado tick fever
- Rocky Mountain spotted fever
- Tick bite
- Tick paralysis
