New to the world of medical coding? ICD-9-CM codes are used throughout the healthcare industry to describe diseases, injuries, symptoms and conditions. CPT codes are used to describe medical and surgical services performed by healthcare providers. ICD-9-CM codes and CPT codes are inherently related, as the diagnosis (ICD-9-CM code) must support the procedure (CPT code). All Medicare claims require a valid ICD-9-CM diagnosis code and a CPT procedure code in order to be reimbursed.
