November 2025 billing policy updates

We publish billing policies to offer transparency and help you bill claims more accurately to reduce delays in processing claims, as well as avoid rebilling and additional requests for information.

The following billing policies were recently published to or updated in our Provider Manual’s Billing Policies page.

Note: If the effective date is listed as N/A, the policy represents our current system set up and/or expectations for transparency. There are either no changes for you as the policy is already in effect or was recently shared with the network and we’re implementing a clinical edit in alignment with the policy’s language.
