If hospitals in a country don’t use the ICD standard, it would cause some problems. First, without a common way to classify diseases, it would be hard to keep accurate records and share information. This would make it tough to see how diseases are changing and plan for public health. Also, not using the ICD standard might mean that insurance claims aren’t paid, since the ICD is important for diagnosing and managing health issues. Not having the ICD standard would make healthcare less efficient and make it harder for different countries to work together on health problems.
