Myth #2: Because there are substantially more codes in ICD-10, it is more complex and difficult to use.

Fact: Complexity and difficulty of use is assumed to be a byproduct of a larger number of codes because it is assumed that physicians and other providers will be burdened by the totality of the number of codes, implying that each provider will have the need to use all the codes. However, physicians and other providers will only use the subset of ICD-10 that is relevant to their patient population (i.e., an ophthalmologist will primarily use only the eye codes).
