"Yes, there are regulatory and accreditation directives that require providers to supply documentation in order to support code assignment. Providers need to have the ability to specifically document the patient's diagnosis, condition and/or problem. It is not appropriate for providers to list the code number or select a code number from a list of codes in place of a written diagnostic statement. ICD-10- CM is a statistical classification, per se, it is not a diagnosis. Some ICD-10-CM codes include multiple different clinical diagnoses and it can be of clinical importance to convey these diagnoses specifically in the record. Also some diagnoses require more than one ICD-10-CM code to fully convey the patient's condition. It is the provider's responsibility to provide clear and legible documentation of a diagnosis, which is then translated to a code for external reporting purposes."
