Radiology billing in 2026 is one of the most demanding areas of medical revenue cycle management. Tighter CMS enforcement, stricter medical necessity reviews, and payer specific coding rules have increased denial risk across diagnostic and interventional imaging. Even small documentation or modifier errors can now lead to delayed or reduced reimbursement.
Recent Medicare reimbursement changes have intensified the pressure. Cuts to the conversion factor and reduced payments for high volume modalities such as CT and MRI mean radiology practices must maintain near perfect billing accuracy to protect margins. In this environment, outsourcing billing is no longer about convenience. It is about revenue protection, compliance, and long term financial stability.
