 ## Code review monthly quota
 
-When you assign {% data variables.product.prodname_copilot_short %} as a reviewer for a pull request—or when you request {% data variables.product.prodname_copilot_short %} to review all of your uncommitted changes in your IDE—your monthly quota of Copilot premium requests is reduced by one. For information about premium requests, see [AUTOTITLE](/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests).
+Each time {% data variables.product.prodname_copilot_short %} reviews a pull request, or reviews files in your IDE that contain changes, your monthly quota of Copilot premium requests is reduced by one. Code review for currently selected text in {% data variables.product.prodname_vscode_shortname %} does not consume a premium request. For information about premium requests, see [AUTOTITLE](/copilot/managing-copilot/monitoring-usage-and-entitlements/about-premium-requests).
 
 If a repository is configured to automatically request a code review from {% data variables.product.prodname_copilot_short %} for all new pull requests, the premium request usage is applied to the quota of the pull request author. If a pull request is created by {% data variables.product.prodname_actions %} or by a bot, the usage will apply to the user who triggered the workflow (if identifiable), or to a designated billing owner.
 
 When you reach your monthly quota you will not be able to get a code review from {% data variables.product.prodname_copilot_short %} until your quota resets—unless you upgrade your {% data variables.product.prodname_copilot_short %} plan or enable additional premium requests.
