Caisson disease

This code represents decompression sickness, also known as caisson disease or "the bends." It is a condition caused by the formation of nitrogen bubbles in the body due to a rapid decrease in ambient pressure, typically experienced by divers or individuals working in pressurized environments. Symptoms can range from joint pain and skin rash to neurological impairment and respiratory distress.

Use this code when documenting a diagnosis of decompression sickness resulting from activities such as scuba diving, deep-sea diving, or working in hyperbaric chambers. Documentation should clearly indicate exposure to pressure changes and the subsequent development of characteristic symptoms consistent with nitrogen bubble formation.

• Differentiate from arterial gas embolism, which is a distinct condition with different causes and treatment.
• Ensure documentation specifies the type of decompression sickness if known (e.g., Type I or Type II).
• Consider sequencing this code as the primary diagnosis when it is the reason for the encounter.
