What is the consequence when a medical practice does not use diagnostic codes?

When a medical practice fails to use diagnostic codes, it can lead to significant issues such as incorrect billing and reimbursement denials from insurance companies. This not only affects the financial stability of the practice but can also hinder patient care by obstructing accurate medical records and treatment planning. Additionally, lack of proper coding may result in compliance issues and potential legal repercussions for failing to meet healthcare regulations.
