Summary
Illinois Department of Healthcare and Family Services is providing guidance on three billing issues affecting community behavioral health services: rate adjustments for services from January-May 2022, telehealth modifier system fixes for duplicate denials, and non-payment of add-ons with GT modifier. Providers must submit replacement claims or rebill affected claims within specified timeframes.
Action Required
By July 8, 2023 (180 days from notice): Rebill any telehealth claims that were denied as duplicates due to modifier GT or 93 issues for services from October 1, 2021 forward. By original voucher date + 1 year: Submit replacement claims (frequency code 7) for January 1-May 5, 2022 services eligible for increased rates and for GT modifier services from October 1, 2021-December 28, 2022 missing add-on payments. For claims over 1 year old, void with frequency code 8 and rebill as original claims with frequency code 1. Contact community mental health billing consultant at 877-782-5565 (option 1,2,4,8) for timely filing overrides when needed.
