Optum - Change Healthcare outage and payment service update

Optum - Change Healthcare (CHC) is our vendor to print checks, provide electronic explanation of payments (EOPs), and for coordination with banks for claim payments. CHC, a subsidiary of UnitedHealth Group, is experiencing a cyber-security issue.

Once we became aware of the outside threat, in the interest of protecting our partners and members, we took immediate action to disconnect our systems to prevent impact. Click here to stay informed of the situation. UnitedHealth Group is providing regular updates on a newly launched website. For additional information, please read our FAQ guide.

To mitigate the issue and minimize further financial impacts to our providers, starting April 10, 2024, we’re switching from Change Healthcare to InstaMed for payment services.

InstaMed registration information:

  • If you are already registered with InstaMed from any payer, you’re already set up to start receiving payments through Instamed.
  • If you are not registered, InstaMed will issue paper checks.
  • If you would like to avoid paper checks, please see below on how to register with InstaMed.

Important information:

  • Medicaid EFT Payments: EFT payments will temporarily indicate they are from Medica or Dean Health Plan. Please check the first claim on the remit to confirm it is a CCHP or Care4Kids (C4K) remit. The remits will only have CCHP or C4K member payments and will not be combined with Medica or Dean Health Plan members. In most cases a unique identifier is returned to a provider when submitting electronic claims. This unique identifier will be sent back on the remit and automatically post correctly with CCHP as the payer. If there is not a unique identifier it is recommended to check the first claim on the remit to confirm the file posted to the correct payer. Please contact CCHP Provider Services at 1-800-482-8010 with any questions regarding claim payments.
  • Medicaid Paper Checks: Paper checks and paper remits received will temporarily indicate they are from Medica or Dean Health Plan. Please check the first claim on the remit to confirm it is a CCHP or Care4Kids (C4K) payment and remit. The remits will only list CCHP member payments and will not be combined with Medica or Dean Health Plan members. Please contact CCHP Provider Services at 1-800-482-8010 with any questions regarding claim payments.

We are working on removing the reference to Medica and Dean and replacing it with CCHP. We do not have a timeline for this change. We will provide updates as we learn more.

New Provider Auth Portal

Guiding Care important information

CCHP has launched a new Provider Authorization Portal through Guiding Care. No authorizations will be accepted in CareWeb and will need to be submitted in Guiding Care.

Guiding Care updates:

  • Have you watched the training videos and read the how-to guides? We have many resources available to you here.
  • On 5/3 we sent an update regarding our authorization portal incorrectly reading dates for services which has led to improper processing and denial of some claims. Unfortunately, we have continued to face these issues. Our team is working hard to correct this promptly and we will send an update when the issue has been resolved. As a reminder, you are still able to submit authorizations in the meantime and please do not appeal these claims as they will be reprocessed.

Thank you for your ongoing partnership in providing high quality care to our members!

Recredentialing Notice for Wisconsin Health Insurance Providers

To assist practitioners with the challenges to timeliness during COVID, CCHP had extended the recredentialing cycle by two months, going from 36 months to 38 months during the Public Health Emergency (PHE). With the PHE set to expire in May 2023, CCHP will return to the 36 month cycle as designated by law, therefore any practitioner who does not submit their completed recredentialing application within the cycle will be terminated.

APNP – Collaborative Agreement

In compliance with the executive order during the Public Health Emergency, CCHP had waived the collaborative agreement requirement for APNPs. With the PHE set to expire in May 2023, CCHP will once again require a Collaborative Agreement per Wisconsin State law. APNP’s without a collaborative agreement by May 18, 2023 will receive a summary suspension of their network privileges.
