Happy Halloween 2018!

Each year, October 31 is celebrated as Halloween day, in remembrance of the dead. With celebrity costumes, scary appearances, witches and spooks, the day will be vibrant, exciting and eerie. However, injuries are also common during Halloween. While documenting such injuries, healthcare providers as well as medical coding companies must be aware of the associated medical codes. Halloween is considered a dangerous time for a pedestrian.

According to a JAMA report, over these Halloweens from 1975 to 2016, a total of 608 pedestrians died – a 43 percent increase compared to random fall nights. Pedestrian traffic risk increases, as celebrations occur at dusk, masks restrict peripheral vision, costumes limit visibility, street-crossing safety is neglected, and some partygoers are impaired by alcohol.

In its recent blog, AAPC discussed some of the ICD-10 codes to document Halloween related injuries. Some of them are funny too.

Get familiar with these codes.
