Changes to E/M Codes

The CMS has updated the medical coding and documentation requirements to address the administrative workloads of physicians. There are a substantial number of changes in the E/M codes to make sure the practices streamline their administrative work. Here is the detail of the coding changes:

Taxonomy for Artificial Intelligence

The E/M code set for 2023 includes a new appendix for artificial intelligence and its applications. The AMA believes that this will guide how AI-based medical services and solutions based on machine learning and other algorithms will be classified. The taxonomy classifies AI-enabled systems as assistive, augmentative, or autonomous.

Medicare Payments Changes

CMS has announced that there will be a separate coding for chronic care management services. Also, the healthcare professionals who can provide this care are also defined by CMS. In addition, the new HCPCS codes will be used to report chronic care services according to the CMS. Similarly, there are additions in the list of telehealth services offered to patients. Some of the telehealth services will stay temporarily and some will stay permanently in 2023.

The Way Forward

Based on this discussion, it can be inferred that CMS has brought changes in the E/M coding and providers need to stay updated about it. Similarly, medical practices should not lose out on revenue and reimbursements due to these changes. Although CPT coding changes positively affect the revenue cycle by reducing the administrative burden on staff, practices may need professional coders and billers to streamline reimbursements, drive efficiency, and enhance financial performance. Staying aligned with the CPT coding changes help providers achieve financial stability and avoid costly mistakes. So, healthcare providers from all specialties should keep an eye on the latest changes announced by AMA to make sure they avoid coding errors to save their time and money
