Based on extensive market feedback, the AMA confirmed that our long-standing “User” definition works well for many, but not for all, applications where CPT data files are used.

Counting Users for EMR, Patient Billing & Practice Management Vendors

With the goal of addressing some of the cases where counting users was not working well, AMA introduced the User Proxy Model—a method of approximating users using base metrics (e.g., staffed beds) and multipliers based on industry data—to determine the number of users for electronic medical records (EMRs/EHRs), patient billing systems and practice management systems.

The User Proxy Model and its underlying base metrics and multipliers were tested extensively in 2016. Feedback indicated:

  • The User Proxy Model is straightforward to use
  • The User Proxy Model provides a consistent and transparent method to determine appropriate licensure for CPT data files

Based on this feedback, the AMA has designated the User Proxy Model as the standard for determining appropriate licensure for EMRs, patient billing systems and practice management systems.

The AMA uses standard health industry data for the purposes of determining the appropriate number of users for licensing CPT. The sources of data include, but are not limited to, HIMSS Analytics, the American Hospital Association, CMS Attestation Reports and information available in the public domain.
