The ICD-10 Procedure Coding System is a way to classify medical procedures that are done. It assigns a special code to each procedure so that it can be easily tracked, stored, and understood. The codes allow doctors, hospitals, and other healthcare providers to talk to each other about the procedures that have been done. This helps make sure that everyone knows which procedure was done, and when. It also helps to ensure that insurance companies are paying for the right medical services, and that people receive the right treatments.
