Please don't include any patient information.

Encrypted in transit and at rest. We sign a BAA before any PHI is shared. No spam, ever. What you send is used only to respond to your request and is stored in our access-controlled systems — never sold or shared with advertisers. See our privacy notice.

What changes

  • Sessions delivered past the authorized hours or units

    Authorizations tracked by hours and units so services stay covered

  • Denials from modifier and rendering-provider rules

    Payer- and state-specific modifier and rendering-provider rules applied up front

  • Credentialing gaps holding up new clinicians

    BCBAs, RBTs and clinicians credentialed and re-credentialed on time
