Pressure Sores
Pressure sores are areas of damaged skin caused by staying in one position for too long. They commonly form where your bones are close to your skin, such as your ankles, back, elbows, heels and hips. You are at risk if you are bedridden, use a wheelchair, or are unable to change your position.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
